# BMad Method V2
# The BMAD-Method 3.1 (Breakthrough Method of Agile (ai-driven) Development)
V2 was the major fix to the shortcomings of V1.
Old Versions:
[Prior Version 1](https://github.com/bmadcode/BMAD-METHOD/tree/V1)
[Prior Version 2](https://github.com/bmadcode/BMAD-METHOD/tree/V2)
Templates were introduced, and separated from the agents themselves. Also aside from templates, checklists were introduced to give more power in actually vetting the the documents or artifacts being produced were valid and of high quality through a forced round of advanced elicitation.
## Do This First, and all will make sense
During V2, this is where the discovery of the power of Gemini Gems and Custom GPTs came to light, really indicating how powerful and cost effective it can be to utilize the Web for a lot of the initial planning, but doing it in a structured repeatable way!
There are lots of docs here, but I HIGHLY suggest you just try the Web Agent - it takes just a few minutes to set up in Gemini - and you can use the BMad Agent to explain how this method works, how to set up in the IDE, how to set up in the Web, what should be done in the web or ide (although you can choose your own path also!) - all just by talking to the bmad agent!
The Web Agents were all granular and clearly defined - a much simpler system, but also somewhat of a pain to create each agent separately in the web while also having to manually export and reimport each document when going agent to agent.
### Web Quickstart Project Setup (Recommended)
Also one confusing aspect was that there were duplicates of temples and checklists for the web versions and the ide versions.
Orchestrator Uber BMad Agent that does it all - already pre-compiled in the `web-build-sample` folder.
But - overall, this was a very low bar to entry to pick up and start using it - The agent personas were all still pretty self contained, aside from calling out to separate template files for the documents.
- The contents of [Agent Prompt Sample](web-build-sample/agent-prompt.txt) text get pasted into the Gemini Gem, or ChatPGT customGPT 'Instructions' field.
- The remaining files in that same folder folder just need to be attached as shown in the screenshot below. Give it a name (such as BMad Agent) and save it, and you now have the BMad Agent available to help you brainstorm, research, plan, execute on your vision, or understand how this all even works!
- Once its running, start with typing `/help`, and then type option `2` when it presents 3 options to learn about the method!

# BMad Hacker Daily Digest API Reference
This document describes the external APIs consumed by the BMad Hacker Daily Digest application.
## External APIs Consumed
### Algolia Hacker News (HN) Search API
- **Purpose:** Used to fetch the top Hacker News stories and the comments associated with each story.
- **Base URL:** `http://hn.algolia.com/api/v1`
- **Authentication:** None required for public search endpoints.
- **Key Endpoints Used:**
- **`GET /search` (for Top Stories)**
- Description: Retrieves stories based on search parameters. Used here to get top stories from the front page.
- Request Parameters:
- `tags=front_page`: Required to filter for front-page stories.
- `hitsPerPage=10`: Specifies the number of stories to retrieve (adjust as needed, default is typically 20).
- Example Request (Conceptual using native `Workspace`):
```typescript
// Using Node.js native Workspace API
const url =
"[http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10](http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10)";
const response = await fetch(url);
const data = await response.json();
```
- Success Response Schema (Code: `200 OK`): See "Algolia HN API - Story Response Subset" in `docs/data-models.md`. Primarily interested in the `hits` array containing story objects.
- Error Response Schema(s): Standard HTTP errors (e.g., 4xx, 5xx). May return JSON with an error message.
- **`GET /search` (for Comments)**
- Description: Retrieves comments associated with a specific story ID.
- Request Parameters:
- `tags=comment,story_{storyId}`: Required to filter for comments belonging to the specified `storyId`. Replace `{storyId}` with the actual ID (e.g., `story_12345`).
- `hitsPerPage={maxComments}`: Specifies the maximum number of comments to retrieve (value from `.env` `MAX_COMMENTS_PER_STORY`).
- Example Request (Conceptual using native `Workspace`):
```typescript
// Using Node.js native Workspace API
const storyId = "..."; // HN Story ID
const maxComments = 50; // From config
const url = `http://hn.algolia.com/api/v1/search?tags=comment,story_${storyId}&hitsPerPage=${maxComments}`;
const response = await fetch(url);
const data = await response.json();
```
- Success Response Schema (Code: `200 OK`): See "Algolia HN API - Comment Response Subset" in `docs/data-models.md`. Primarily interested in the `hits` array containing comment objects.
- Error Response Schema(s): Standard HTTP errors.
- **Rate Limits:** Subject to Algolia's public API rate limits (typically generous for HN search but not explicitly defined/guaranteed). Implementations should handle potential 429 errors gracefully if encountered.
- **Link to Official Docs:** [https://hn.algolia.com/api](https://hn.algolia.com/api)
### Ollama API (Local Instance)
- **Purpose:** Used to generate text summaries for scraped article content and HN comment discussions using a locally running LLM.
- **Base URL:** Configurable via the `OLLAMA_ENDPOINT_URL` environment variable (e.g., `http://localhost:11434`).
- **Authentication:** None typically required for default local installations.
- **Key Endpoints Used:**
- **`POST /api/generate`**
- Description: Generates text based on a model and prompt. Used here for summarization.
- Request Body Schema: See `OllamaGenerateRequest` in `docs/data-models.md`. Requires `model` (from `.env` `OLLAMA_MODEL`), `prompt`, and `stream: false`.
- Example Request (Conceptual using native `Workspace`):
```typescript
// Using Node.js native Workspace API
const ollamaUrl =
process.env.OLLAMA_ENDPOINT_URL || "http://localhost:11434";
const requestBody: OllamaGenerateRequest = {
model: process.env.OLLAMA_MODEL || "llama3",
prompt: "Summarize this text: ...",
stream: false,
};
const response = await fetch(`${ollamaUrl}/api/generate`, {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify(requestBody),
});
const data: OllamaGenerateResponse | { error: string } =
await response.json();
```
- Success Response Schema (Code: `200 OK`): See `OllamaGenerateResponse` in `docs/data-models.md`. Key field is `response` containing the generated text.
- Error Response Schema(s): May return non-200 status codes or a `200 OK` with a JSON body like `{ "error": "error message..." }` (e.g., if the model is unavailable).
- **Rate Limits:** N/A for a typical local instance. Performance depends on local hardware.
- **Link to Official Docs:** [https://github.com/ollama/ollama/blob/main/docs/api.md](https://github.com/ollama/ollama/blob/main/docs/api.md)
## Internal APIs Provided
- **N/A:** The application is a self-contained CLI tool and does not expose any APIs for other services to consume.
## Cloud Service SDK Usage
- **N/A:** The application runs locally and uses the native Node.js `Workspace` API for HTTP requests, not cloud provider SDKs.

# BMad Hacker Daily Digest Architecture Document
## Technical Summary
The BMad Hacker Daily Digest is a command-line interface (CLI) tool designed to provide users with concise summaries of top Hacker News (HN) stories and their associated comment discussions . Built with TypeScript and Node.js (v22) , it operates entirely on the user's local machine . The core functionality involves a sequential pipeline: fetching story and comment data from the Algolia HN Search API , attempting to scrape linked article content , generating summaries using a local Ollama LLM instance , persisting intermediate data to the local filesystem , and finally assembling and emailing an HTML digest using Nodemailer . The architecture emphasizes modularity and testability, including mandatory standalone scripts for testing each pipeline stage . The project starts from the `bmad-boilerplate` template .
## High-Level Overview
The application follows a simple, sequential pipeline architecture executed via a manual CLI command (`npm run dev` or `npm start`) . There is no persistent database; the local filesystem is used to store intermediate data artifacts (fetched data, scraped text, summaries) between steps within a date-stamped directory . All external HTTP communication (Algolia API, article scraping, Ollama API) utilizes the native Node.js `Workspace` API .

## Component View
The application code (`src/`) is organized into logical modules based on the defined project structure (`docs/project-structure.md`). Key components include:
- **`src/index.ts`**: The main entry point, handling CLI invocation and initiating the pipeline.
- **`src/core/pipeline.ts`**: Orchestrates the sequential execution of the main pipeline stages (fetch, scrape, summarize, email).
- **`src/clients/`**: Modules responsible for interacting with external APIs.
- `algoliaHNClient.ts`: Communicates with the Algolia HN Search API.
- `ollamaClient.ts`: Communicates with the local Ollama API.
- **`src/scraper/articleScraper.ts`**: Handles fetching and extracting text content from article URLs.
- **`src/email/`**: Manages digest assembly, HTML rendering, and email dispatch via Nodemailer.
- `contentAssembler.ts`: Reads persisted data.
- `templates.ts`: Renders HTML.
- `emailSender.ts`: Sends the email.
- **`src/stages/`**: Contains standalone scripts (`Workspace_hn_data.ts`, `scrape_articles.ts`, etc.) for testing individual pipeline stages independently using local data where applicable.
- **`src/utils/`**: Shared utilities for configuration loading (`config.ts`), logging (`logger.ts`), and date handling (`dateUtils.ts`).
- **`src/types/`**: Shared TypeScript interfaces and types.

## Key Architectural Decisions & Patterns
- **Architecture Style:** Simple Sequential Pipeline executed via CLI.
- **Execution Environment:** Local machine only; no cloud deployment, no database for MVP.
- **Data Handling:** Intermediate data persisted to local filesystem in a date-stamped directory.
- **HTTP Client:** Mandatory use of native Node.js v22 `Workspace` API for all external HTTP requests.
- **Modularity:** Code organized into distinct modules for clients, scraping, email, core logic, utilities, and types to promote separation of concerns and testability.
- **Stage Testing:** Mandatory standalone scripts (`src/stages/*`) allow independent testing of each pipeline phase.
- **Configuration:** Environment variables loaded natively from `.env` file; no `dotenv` package required.
- **Error Handling:** Graceful handling of scraping failures (log and continue); basic logging for other API/network errors.
- **Logging:** Basic console logging via a simple wrapper (`src/utils/logger.ts`) for MVP; structured file logging is a post-MVP consideration.
- **Key Libraries:** `@extractus/article-extractor`, `date-fns`, `nodemailer`, `yargs`. (See `docs/tech-stack.md`)

## Infrastructure and Deployment Overview
- **Cloud Provider(s):** N/A. Executes locally on the user's machine.
- **Core Services Used:** N/A (relies on external Algolia API, local Ollama, target websites, SMTP provider).
- **Infrastructure as Code (IaC):** N/A.
- **Deployment Strategy:** Manual execution via CLI (`npm run dev` or `npm run start` after `npm run build`). No CI/CD pipeline required for MVP.
- **Environments:** Single environment: local development machine.

# BMad Hacker Daily Digest Architecture Document
## Technical Summary
The BMad Hacker Daily Digest is a command-line interface (CLI) tool designed to provide users with concise summaries of top Hacker News (HN) stories and their associated comment discussions . Built with TypeScript and Node.js (v22) , it operates entirely on the user's local machine . The core functionality involves a sequential pipeline: fetching story and comment data from the Algolia HN Search API , attempting to scrape linked article content , generating summaries using a local Ollama LLM instance , persisting intermediate data to the local filesystem , and finally assembling and emailing an HTML digest using Nodemailer . The architecture emphasizes modularity and testability, including mandatory standalone scripts for testing each pipeline stage . The project starts from the `bmad-boilerplate` template .
## High-Level Overview
The application follows a simple, sequential pipeline architecture executed via a manual CLI command (`npm run dev` or `npm start`) . There is no persistent database; the local filesystem is used to store intermediate data artifacts (fetched data, scraped text, summaries) between steps within a date-stamped directory . All external HTTP communication (Algolia API, article scraping, Ollama API) utilizes the native Node.js `Workspace` API .

## Component View
The application code (`src/`) is organized into logical modules based on the defined project structure (`docs/project-structure.md`). Key components include:
- **`src/index.ts`**: The main entry point, handling CLI invocation and initiating the pipeline.
- **`src/core/pipeline.ts`**: Orchestrates the sequential execution of the main pipeline stages (fetch, scrape, summarize, email).
- **`src/clients/`**: Modules responsible for interacting with external APIs.
- `algoliaHNClient.ts`: Communicates with the Algolia HN Search API.
- `ollamaClient.ts`: Communicates with the local Ollama API.
- **`src/scraper/articleScraper.ts`**: Handles fetching and extracting text content from article URLs.
- **`src/email/`**: Manages digest assembly, HTML rendering, and email dispatch via Nodemailer.
- `contentAssembler.ts`: Reads persisted data.
- `templates.ts`: Renders HTML.
- `emailSender.ts`: Sends the email.
- **`src/stages/`**: Contains standalone scripts (`Workspace_hn_data.ts`, `scrape_articles.ts`, etc.) for testing individual pipeline stages independently using local data where applicable.
- **`src/utils/`**: Shared utilities for configuration loading (`config.ts`), logging (`logger.ts`), and date handling (`dateUtils.ts`).
- **`src/types/`**: Shared TypeScript interfaces and types.

## Key Architectural Decisions & Patterns
- **Architecture Style:** Simple Sequential Pipeline executed via CLI.
- **Execution Environment:** Local machine only; no cloud deployment, no database for MVP.
- **Data Handling:** Intermediate data persisted to local filesystem in a date-stamped directory.
- **HTTP Client:** Mandatory use of native Node.js v22 `Workspace` API for all external HTTP requests.
- **Modularity:** Code organized into distinct modules for clients, scraping, email, core logic, utilities, and types to promote separation of concerns and testability.
- **Stage Testing:** Mandatory standalone scripts (`src/stages/*`) allow independent testing of each pipeline phase.
- **Configuration:** Environment variables loaded natively from `.env` file; no `dotenv` package required.
- **Error Handling:** Graceful handling of scraping failures (log and continue); basic logging for other API/network errors.
- **Logging:** Basic console logging via a simple wrapper (`src/utils/logger.ts`) for MVP; structured file logging is a post-MVP consideration.
- **Key Libraries:** `@extractus/article-extractor`, `date-fns`, `nodemailer`, `yargs`. (See `docs/tech-stack.md`)

# BMad Hacker Daily Digest Architecture Document
## Technical Summary
This document outlines the technical architecture for the BMad Hacker Daily Digest, a command-line tool built with TypeScript and Node.js v22. It adheres to the structure provided by the "bmad-boilerplate". The system fetches the top 10 Hacker News stories and their comments daily via the Algolia HN API, attempts to scrape linked articles, generates summaries for both articles (if scraped) and discussions using a local Ollama instance, persists intermediate data locally, and sends an HTML digest email via Nodemailer upon manual CLI execution. The architecture emphasizes modularity through distinct clients and processing stages, facilitating independent stage testing as required by the PRD. Execution is strictly local for the MVP.
## High-Level Overview
The application follows a sequential pipeline architecture triggered by a single CLI command (`npm run dev` or `npm start`). Data flows through distinct stages: HN Data Acquisition, Article Scraping, LLM Summarization, and Digest Assembly/Email Dispatch. Each stage persists its output to a date-stamped local directory, allowing subsequent stages to operate on this data and enabling stage-specific testing utilities.
**(Diagram Suggestion for Canvas: Create a flowchart showing the stages below)**
```mermaid
graph TD
A[CLI Trigger (npm run dev/start)] --> B(Initialize: Load Config, Setup Logger, Create Output Dir);
B --> C{Fetch HN Data (Top 10 Stories + Comments)};
C -- Story/Comment Data --> D(Persist HN Data: ./output/YYYY-MM-DD/{storyId}_data.json);
D --> E{Attempt Article Scraping (per story)};
E -- Scraped Text (if successful) --> F(Persist Article Text: ./output/YYYY-MM-DD/{storyId}_article.txt);
F --> G{Generate Summaries (Article + Discussion via Ollama)};
G -- Summaries --> H(Persist Summaries: ./output/YYYY-MM-DD/{storyId}_summary.json);
H --> I{Assemble Digest (Read persisted data)};
I -- HTML Content --> J{Send Email via Nodemailer};
J --> K(Log Final Status & Exit);

E --> |Skip/Fail| G; // If no URL or scrape fails
G --> |Summarization Fail| H; // Persist null summaries
I --> |Assembly Fail| K; // Skip email if assembly fails
```
## Component View
The application logic resides primarily within the `src/` directory, organized into modules responsible for specific pipeline stages or cross-cutting concerns.

_Module Descriptions:_
- **`src/index.ts`**: The main entry point, orchestrating the entire pipeline flow from initialization to final email dispatch. Imports and calls functions from other modules.
- **`src/config.ts`**: Responsible for loading and validating environment variables from the `.env` file using the `dotenv` library.
- **`src/logger.ts`**: Provides a simple console logging utility used throughout the application.
- **`src/clients/algoliaHNClient.ts`**: Encapsulates interaction with the Algolia Hacker News Search API using the native `Workspace` API for fetching stories and comments.
- **`src/clients/ollamaClient.ts`**: Encapsulates interaction with the local Ollama API endpoint using the native `Workspace` API for generating summaries.
- **`src/scraper/articleScraper.ts`**: Handles fetching article HTML using native `Workspace` and extracting text content using `@extractus/article-extractor`. Includes robust error handling for fetch and extraction failures.
- **`src/email/contentAssembler.ts`**: Reads persisted story data and summaries from the local output directory.
- **`src/email/templater.ts` (or integrated)**: Renders the HTML email content using the assembled data.
- **`src/email/emailSender.ts`**: Configures and uses Nodemailer to send the generated HTML email.
- **`src/stages/*.ts`**: Individual scripts designed to run specific pipeline stages independently for testing, using persisted data from previous stages as input where applicable.
## Key Architectural Decisions & Patterns
- **Pipeline Architecture:** A sequential flow where each stage processes data and passes artifacts to the next via the local filesystem. Chosen for simplicity and to easily support independent stage testing.
- **Local Execution & File Persistence:** All execution is local, and intermediate artifacts (`_data.json`, `_article.txt`, `_summary.json`) are stored in a date-stamped `./output` directory. This avoids database setup for MVP and facilitates debugging/stage testing.
- **Native `Workspace` API:** Mandated by constraints for all HTTP requests (Algolia, Ollama, Article Scraping). Ensures usage of the latest Node.js features.
- **Modular Clients:** External interactions (Algolia, Ollama) are encapsulated in dedicated client modules (`src/clients/`). This promotes separation of concerns and makes swapping implementations (e.g., different LLM API) easier.
- **Configuration via `.env`:** Standard approach using `dotenv` for managing API keys, endpoints, and behavioral parameters (as per boilerplate).
- **Stage Testing Utilities:** Dedicated scripts (`src/stages/*.ts`) allow isolated testing of fetching, scraping, summarization, and emailing, fulfilling a key PRD requirement.
- **Graceful Error Handling (Scraping):** Article scraping failures are logged but do not halt the main pipeline, allowing the process to continue with discussion summaries only, as required. Other errors (API, LLM) are logged.

# BMad Hacker Daily Digest Coding Standards and Patterns
This document outlines the coding standards, design patterns, and best practices to be followed during the development of the BMad Hacker Daily Digest project. Adherence to these standards is crucial for maintainability, readability, and collaboration.
## Architectural / Design Patterns Adopted
- **Sequential Pipeline:** The core application follows a linear sequence of steps (fetch, scrape, summarize, email) orchestrated within `src/core/pipeline.ts`.
- **Modular Design:** The application is broken down into distinct modules based on responsibility (e.g., `clients/`, `scraper/`, `email/`, `utils/`) to promote separation of concerns, testability, and maintainability. See `docs/project-structure.md`.
- **Client Abstraction:** External service interactions (Algolia, Ollama) are encapsulated within dedicated client modules in `src/clients/`.
- **Filesystem Persistence:** Intermediate data is persisted to the local filesystem instead of a database, acting as a handoff between pipeline stages.
## Coding Standards
- **Primary Language:** TypeScript (v5.x, as configured in boilerplate)
- **Primary Runtime:** Node.js (v22.x, as required by PRD )
- **Style Guide & Linter:** ESLint and Prettier. Configuration is provided by the `bmad-boilerplate`.
- **Mandatory:** Run `npm run lint` and `npm run format` regularly and before committing code. Code must be free of lint errors.
- **Naming Conventions:**
- Variables & Functions: `camelCase`
- Classes, Types, Interfaces: `PascalCase`
- Constants: `UPPER_SNAKE_CASE`
- Files: `kebab-case.ts` (e.g., `article-scraper.ts`) or `camelCase.ts` (e.g., `ollamaClient.ts`). Be consistent within module types (e.g., all clients follow one pattern, all utils another). Let's default to `camelCase.ts` for consistency with class/module names where applicable (e.g. `ollamaClient.ts`) and `kebab-case.ts` for more descriptive utils or stage runners (e.g. `Workspace-hn-data.ts`).
- Test Files: `*.test.ts` (e.g., `ollamaClient.test.ts`)
- **File Structure:** Adhere strictly to the layout defined in `docs/project-structure.md`.
- **Asynchronous Operations:** **Mandatory:** Use `async`/`await` for all asynchronous operations (e.g., native `Workspace` HTTP calls , `fs/promises` file operations, Ollama client calls, Nodemailer `sendMail`). Avoid using raw Promises `.then()`/`.catch()` syntax where `async/await` provides better readability.
- **Type Safety:** Leverage TypeScript's static typing. Use interfaces and types defined in `src/types/` where appropriate. Assume `strict` mode is enabled in `tsconfig.json` (from boilerplate). Avoid using `any` unless absolutely necessary and justified.
- **Comments & Documentation:**
- Use JSDoc comments for exported functions, classes, and complex logic.
- Keep comments concise and focused on the _why_, not the _what_, unless the code is particularly complex.
- Update READMEs as needed for setup or usage changes.
- **Dependency Management:**
- Use `npm` for package management.
- Keep production dependencies minimal, as required by the PRD . Justify any additions.
- Use `devDependencies` for testing, linting, and build tools.
## Error Handling Strategy
- **General Approach:** Use standard JavaScript `try...catch` blocks for operations that can fail (I/O, network requests, parsing, etc.). Throw specific `Error` objects with descriptive messages. Avoid catching errors without logging or re-throwing unless intentionally handling a specific case.
- **Logging:**
- **Mandatory:** Use the central logger utility (`src/utils/logger.ts`) for all console output (INFO, WARN, ERROR). Do not use `console.log` directly in application logic.
- **Format:** Basic text format for MVP. Structured JSON logging to files is a post-MVP enhancement.
- **Levels:** Use appropriate levels (`logger.info`, `logger.warn`, `logger.error`).
- **Context:** Include relevant context in log messages (e.g., Story ID, function name, URL being processed) to aid debugging.
- **Specific Handling Patterns:**
- **External API Calls (Algolia, Ollama via `Workspace`):**
- Wrap `Workspace` calls in `try...catch`.
- Check `response.ok` status; if false, log the status code and potentially response body text, then treat as an error (e.g., return `null` or throw).
- Log network errors caught by the `catch` block.
- No automated retries required for MVP.
- **Article Scraping (`articleScraper.ts`):**
- Wrap `Workspace` and text extraction (`article-extractor`) logic in `try...catch`.
- Handle non-2xx responses, timeouts, non-HTML content types, and extraction errors.
- **Crucial:** If scraping fails for any reason, log the error/reason using `logger.warn` or `logger.error`, return `null`, and **allow the main pipeline to continue processing the story** (using only comment summary). Do not throw an error that halts the entire application.
- **File I/O (`fs` module):**
- Wrap `fs` operations (especially writes) in `try...catch`. Log any file system errors using `logger.error`.
- **Email Sending (`Nodemailer`):**
- Wrap `transporter.sendMail()` in `try...catch`. Log success (including message ID) or failure clearly using the logger.
- **Configuration Loading (`config.ts`):**
- Check for the presence of all required environment variables at startup. Throw a fatal error and exit if required variables are missing.
- **LLM Interaction (Ollama Client):**
- **LLM Prompts:** Use the standardized prompts defined in `docs/prompts.md` when interacting with the Ollama client for consistency.
- Wrap `generateSummary` calls in `try...catch`. Log errors from the client (which handles API/network issues).
- **Comment Truncation:** Before sending comments for discussion summary, check for the `MAX_COMMENT_CHARS_FOR_SUMMARY` env var. If set to a positive number, truncate the combined comment text block to this length. Log a warning if truncation occurs. If not set, send the full text.
## Security Best Practices
- **Input Sanitization/Validation:** While primarily a local tool, validate critical inputs like external URLs (`story.articleUrl`) before attempting to fetch them. Basic checks (e.g., starts with `http://` or `https://`) are sufficient for MVP .
- **Secrets Management:**
- **Mandatory:** Store sensitive data (`EMAIL_USER`, `EMAIL_PASS`) only in the `.env` file.
- **Mandatory:** Ensure the `.env` file is included in `.gitignore` and is never committed to version control.
- Do not hardcode secrets anywhere in the source code.
- **Dependency Security:** Periodically run `npm audit` to check for known vulnerabilities in dependencies. Consider enabling Dependabot if using GitHub.
- **HTTP Client:** Use the native `Workspace` API as required ; avoid introducing less secure or overly complex HTTP client libraries.
- **Scraping User-Agent:** Set a default User-Agent header in the scraper code (e.g., "BMadHackerDigest/0.1"). Allow overriding this default via the optional SCRAPER_USER_AGENT environment variable.

- Test Files: `*.test.ts` (e.g., `ollamaClient.test.ts`)
- **File Structure:** Adhere strictly to the layout defined in `docs/project-structure.md`.
- **Asynchronous Operations:** **Mandatory:** Use `async`/`await` for all asynchronous operations (e.g., native `Workspace` HTTP calls , `fs/promises` file operations, Ollama client calls, Nodemailer `sendMail`). Avoid using raw Promises `.then()`/`.catch()` syntax where `async/await` provides better readability.
- **Type Safety:** Leverage TypeScript's static typing. Use interfaces and types defined in `src/types/` where appropriate. Assume `strict` mode is enabled in `tsconfig.json` (from boilerplate). Avoid using `any` unless absolutely necessary and justified.
- **Comments & Documentation:**
- Use JSDoc comments for exported functions, classes, and complex logic.
- Keep comments concise and focused on the _why_, not the _what_, unless the code is particularly complex.
- Update READMEs as needed for setup or usage changes.
- **Dependency Management:**
- Use `npm` for package management.
- Keep production dependencies minimal, as required by the PRD . Justify any additions.
- Use `devDependencies` for testing, linting, and build tools.
## Error Handling Strategy
- **General Approach:** Use standard JavaScript `try...catch` blocks for operations that can fail (I/O, network requests, parsing, etc.). Throw specific `Error` objects with descriptive messages. Avoid catching errors without logging or re-throwing unless intentionally handling a specific case.
- **Logging:**
- **Mandatory:** Use the central logger utility (`src/utils/logger.ts`) for all console output (INFO, WARN, ERROR). Do not use `console.log` directly in application logic.
- **Format:** Basic text format for MVP. Structured JSON logging to files is a post-MVP enhancement.
- **Levels:** Use appropriate levels (`logger.info`, `logger.warn`, `logger.error`).
- **Context:** Include relevant context in log messages (e.g., Story ID, function name, URL being processed) to aid debugging.
- **Specific Handling Patterns:**
- **External API Calls (Algolia, Ollama via `Workspace`):**
- Wrap `Workspace` calls in `try...catch`.
- Check `response.ok` status; if false, log the status code and potentially response body text, then treat as an error (e.g., return `null` or throw).
- Log network errors caught by the `catch` block.
- No automated retries required for MVP.
- **Article Scraping (`articleScraper.ts`):**
- Wrap `Workspace` and text extraction (`article-extractor`) logic in `try...catch`.
- Handle non-2xx responses, timeouts, non-HTML content types, and extraction errors.
- **Crucial:** If scraping fails for any reason, log the error/reason using `logger.warn` or `logger.error`, return `null`, and **allow the main pipeline to continue processing the story** (using only comment summary). Do not throw an error that halts the entire application.
- **File I/O (`fs` module):**
- Wrap `fs` operations (especially writes) in `try...catch`. Log any file system errors using `logger.error`.
- **Email Sending (`Nodemailer`):**
- Wrap `transporter.sendMail()` in `try...catch`. Log success (including message ID) or failure clearly using the logger.
- **Configuration Loading (`config.ts`):**
- Check for the presence of all required environment variables at startup. Throw a fatal error and exit if required variables are missing.
- **LLM Interaction (Ollama Client):**
- **LLM Prompts:** Use the standardized prompts defined in `docs/prompts.md` when interacting with the Ollama client for consistency.
- Wrap `generateSummary` calls in `try...catch`. Log errors from the client (which handles API/network issues).
- **Comment Truncation:** Before sending comments for discussion summary, check for the `MAX_COMMENT_CHARS_FOR_SUMMARY` env var. If set to a positive number, truncate the combined comment text block to this length. Log a warning if truncation occurs. If not set, send the full text.
## Security Best Practices
- **Input Sanitization/Validation:** While primarily a local tool, validate critical inputs like external URLs (`story.articleUrl`) before attempting to fetch them. Basic checks (e.g., starts with `http://` or `https://`) are sufficient for MVP .
- **Secrets Management:**
- **Mandatory:** Store sensitive data (`EMAIL_USER`, `EMAIL_PASS`) only in the `.env` file.
- **Mandatory:** Ensure the `.env` file is included in `.gitignore` and is never committed to version control.
- Do not hardcode secrets anywhere in the source code.
- **Dependency Security:** Periodically run `npm audit` to check for known vulnerabilities in dependencies. Consider enabling Dependabot if using GitHub.
- **HTTP Client:** Use the native `Workspace` API as required ; avoid introducing less secure or overly complex HTTP client libraries.
- **Scraping User-Agent:** Set a default User-Agent header in the scraper code (e.g., "BMadHackerDigest/0.1"). Allow overriding this default via the optional SCRAPER_USER_AGENT environment variable.

# Epic 1 file
# Epic 1: Project Initialization & Core Setup
**Goal:** Initialize the project using the "bmad-boilerplate", manage dependencies, setup `.env` and config loading, establish basic CLI entry point, setup basic logging and output directory structure. This provides the foundational setup for all subsequent development work.
## Story List
### Story 1.1: Initialize Project from Boilerplate
- **User Story / Goal:** As a developer, I want to set up the initial project structure using the `bmad-boilerplate`, so that I have the standard tooling (TS, Jest, ESLint, Prettier), configurations, and scripts in place.
- **Detailed Requirements:**
- Copy or clone the contents of the `bmad-boilerplate` into the new project's root directory.
- Initialize a git repository in the project root directory (if not already done by cloning).
- Ensure the `.gitignore` file from the boilerplate is present.
- Run `npm install` to download and install all `devDependencies` specified in the boilerplate's `package.json`.
- Verify that the core boilerplate scripts (`lint`, `format`, `test`, `build`) execute without errors on the initial codebase.
- **Acceptance Criteria (ACs):**
- AC1: The project directory contains the files and structure from `bmad-boilerplate`.
- AC2: A `node_modules` directory exists and contains packages corresponding to `devDependencies`.
- AC3: `npm run lint` command completes successfully without reporting any linting errors.
- AC4: `npm run format` command completes successfully, potentially making formatting changes according to Prettier rules. Running it a second time should result in no changes.
- AC5: `npm run test` command executes Jest successfully (it may report "no tests found" which is acceptable at this stage).
- AC6: `npm run build` command executes successfully, creating a `dist` directory containing compiled JavaScript output.
- AC7: The `.gitignore` file exists and includes entries for `node_modules/`, `.env`, `dist/`, etc. as specified in the boilerplate.
---
### Story 1.2: Setup Environment Configuration
- **User Story / Goal:** As a developer, I want to establish the environment configuration mechanism using `.env` files, so that secrets and settings (like output paths) can be managed outside of version control, following boilerplate conventions.
- **Detailed Requirements:**
- Add a production dependency for loading `.env` files (e.g., `dotenv`). Run `npm install dotenv --save-prod` (or similar library).
- Verify the `.env.example` file exists (from boilerplate).
- Add an initial configuration variable `OUTPUT_DIR_PATH=./output` to `.env.example`.
- Create the `.env` file locally by copying `.env.example`. Populate `OUTPUT_DIR_PATH` if needed (can keep default).
- Implement a utility module (e.g., `src/config.ts`) that loads environment variables from the `.env` file at application startup.
- The utility should export the loaded configuration values (initially just `OUTPUT_DIR_PATH`).
- Ensure the `.env` file is listed in `.gitignore` and is not committed.
- **Acceptance Criteria (ACs):**
- AC1: The chosen `.env` library (e.g., `dotenv`) is listed under `dependencies` in `package.json` and `package-lock.json` is updated.
- AC2: The `.env.example` file exists, is tracked by git, and contains the line `OUTPUT_DIR_PATH=./output`.
- AC3: The `.env` file exists locally but is NOT tracked by git.
- AC4: A configuration module (`src/config.ts` or similar) exists and successfully loads the `OUTPUT_DIR_PATH` value from `.env` when the application starts.
- AC5: The loaded `OUTPUT_DIR_PATH` value is accessible within the application code.
---
### Story 1.3: Implement Basic CLI Entry Point & Execution
- **User Story / Goal:** As a developer, I want a basic `src/index.ts` entry point that can be executed via the boilerplate's `dev` and `start` scripts, providing a working foundation for the application logic.
- **Detailed Requirements:**
- Create the main application entry point file at `src/index.ts`.
- Implement minimal code within `src/index.ts` to:
- Import the configuration loading mechanism (from Story 1.2).
- Log a simple startup message to the console (e.g., "BMad Hacker Daily Digest - Starting Up...").
- (Optional) Log the loaded `OUTPUT_DIR_PATH` to verify config loading.
- Confirm execution using boilerplate scripts.
- **Acceptance Criteria (ACs):**
- AC1: The `src/index.ts` file exists.
- AC2: Running `npm run dev` executes `src/index.ts` via `ts-node` and logs the startup message to the console.
- AC3: Running `npm run build` successfully compiles `src/index.ts` (and any imports) into the `dist` directory.
- AC4: Running `npm start` (after a successful build) executes the compiled code from `dist` and logs the startup message to the console.
---
### Story 1.4: Setup Basic Logging and Output Directory
- **User Story / Goal:** As a developer, I want a basic console logging mechanism and the dynamic creation of a date-stamped output directory, so that the application can provide execution feedback and prepare for storing data artifacts in subsequent epics.
- **Detailed Requirements:**
- Implement a simple, reusable logging utility module (e.g., `src/logger.ts`). Initially, it can wrap `console.log`, `console.warn`, `console.error`.
- Refactor `src/index.ts` to use this `logger` for its startup message(s).
- In `src/index.ts` (or a setup function called by it):
- Retrieve the `OUTPUT_DIR_PATH` from the configuration (loaded in Story 1.2).
- Determine the current date in 'YYYY-MM-DD' format.
- Construct the full path for the date-stamped subdirectory (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`).
- Check if the base output directory exists; if not, create it.
- Check if the date-stamped subdirectory exists; if not, create it recursively. Use Node.js `fs` module (e.g., `fs.mkdirSync(path, { recursive: true })`).
- Log (using the logger) the full path of the output directory being used for the current run (e.g., "Output directory for this run: ./output/2025-05-04").
- **Acceptance Criteria (ACs):**
- AC1: A logger utility module (`src/logger.ts` or similar) exists and is used for console output in `src/index.ts`.
- AC2: Running `npm run dev` or `npm start` logs the startup message via the logger.
- AC3: Running the application creates the base output directory (e.g., `./output` defined in `.env`) if it doesn't already exist.
- AC4: Running the application creates a date-stamped subdirectory (e.g., `./output/2025-05-04`) within the base output directory if it doesn't already exist.
- AC5: The application logs a message indicating the full path to the date-stamped output directory created/used for the current execution.
- AC6: The application exits gracefully after performing these setup steps (for now).

# Epic 2 File
# Epic 2: HN Data Acquisition & Persistence
**Goal:** Implement fetching top 10 stories and their comments (respecting limits) from Algolia HN API, and persist this raw data locally into the date-stamped output directory created in Epic 1. Implement a stage testing utility for fetching.
## Story List
### Story 2.1: Implement Algolia HN API Client
- **User Story / Goal:** As a developer, I want a dedicated client module to interact with the Algolia Hacker News Search API, so that fetching stories and comments is encapsulated, reusable, and uses the required native `Workspace` API.
- **Detailed Requirements:**
- Create a new module: `src/clients/algoliaHNClient.ts`.
- Implement an async function `WorkspaceTopStories` within the client:
- Use native `Workspace` to call the Algolia HN Search API endpoint for front-page stories (e.g., `http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10`). Adjust `hitsPerPage` if needed to ensure 10 stories.
- Parse the JSON response.
- Extract required metadata for each story: `objectID` (use as `storyId`), `title`, `url` (article URL), `points`, `num_comments`. Handle potential missing `url` field gracefully (log warning, maybe skip story later if URL needed).
- Construct the `hnUrl` for each story (e.g., `https://news.ycombinator.com/item?id={storyId}`).
- Return an array of structured story objects.
- Implement a separate async function `WorkspaceCommentsForStory` within the client:
- Accept `storyId` and `maxComments` limit as arguments.
- Use native `Workspace` to call the Algolia HN Search API endpoint for comments of a specific story (e.g., `http://hn.algolia.com/api/v1/search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`).
- Parse the JSON response.
- Extract required comment data: `objectID` (use as `commentId`), `comment_text`, `author`, `created_at`.
- Filter out comments where `comment_text` is null or empty. Ensure only up to `maxComments` are returned.
- Return an array of structured comment objects.
- Implement basic error handling using `try...catch` around `Workspace` calls and check `response.ok` status. Log errors using the logger utility from Epic 1.
- Define TypeScript interfaces/types for the expected structures of API responses (stories, comments) and the data returned by the client functions (e.g., `Story`, `Comment`).
- **Acceptance Criteria (ACs):**
- AC1: The module `src/clients/algoliaHNClient.ts` exists and exports `WorkspaceTopStories` and `WorkspaceCommentsForStory` functions.
- AC2: Calling `WorkspaceTopStories` makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of 10 `Story` objects containing the specified metadata.
- AC3: Calling `WorkspaceCommentsForStory` with a valid `storyId` and `maxComments` limit makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of `Comment` objects (up to `maxComments`), filtering out empty ones.
- AC4: Both functions use the native `Workspace` API internally.
- AC5: Network errors or non-successful API responses (e.g., status 4xx, 5xx) are caught and logged using the logger.
- AC6: Relevant TypeScript types (`Story`, `Comment`, etc.) are defined and used within the client module.
---
### Story 2.2: Integrate HN Data Fetching into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the HN data fetching logic into the main application workflow (`src/index.ts`), so that running the app retrieves the top 10 stories and their comments after completing the setup from Epic 1.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts` (or a main async function called by it).
- Import the `algoliaHNClient` functions.
- Import the configuration module to access `MAX_COMMENTS_PER_STORY`.
- After the Epic 1 setup (config load, logger init, output dir creation), call `WorkspaceTopStories()`.
- Log the number of stories fetched.
- Iterate through the array of fetched `Story` objects.
- For each `Story`, call `WorkspaceCommentsForStory()`, passing the `story.storyId` and the configured `MAX_COMMENTS_PER_STORY`.
- Store the fetched comments within the corresponding `Story` object in memory (e.g., add a `comments: Comment[]` property to the `Story` object).
- Log progress using the logger utility (e.g., "Fetched 10 stories.", "Fetching up to X comments for story {storyId}...").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 setup steps followed by fetching stories and then comments for each story.
- AC2: Logs clearly show the start and successful completion of fetching stories, and the start of fetching comments for each of the 10 stories.
- AC3: The configured `MAX_COMMENTS_PER_STORY` value is read from config and used in the calls to `WorkspaceCommentsForStory`.
- AC4: After successful execution, story objects held in memory contain a nested array of fetched comment objects. (Can be verified via debugger or temporary logging).
---
### Story 2.3: Persist Fetched HN Data Locally
- **User Story / Goal:** As a developer, I want to save the fetched HN stories (including their comments) to JSON files in the date-stamped output directory, so that the raw data is persisted locally for subsequent pipeline stages and debugging.
- **Detailed Requirements:**
- Define a consistent JSON structure for the output file content. Example: `{ storyId: "...", title: "...", url: "...", hnUrl: "...", points: ..., fetchedAt: "ISO_TIMESTAMP", comments: [{ commentId: "...", text: "...", author: "...", createdAt: "ISO_TIMESTAMP", ... }, ...] }`. Include a timestamp for when the data was fetched.
- Import Node.js `fs` (specifically `fs.writeFileSync`) and `path` modules.
- In the main workflow (`src/index.ts`), within the loop iterating through stories (after comments have been fetched and added to the story object in Story 2.2):
- Get the full path to the date-stamped output directory (determined in Epic 1).
- Construct the filename for the story's data: `{storyId}_data.json`.
- Construct the full file path using `path.join()`.
- Serialize the complete story object (including comments and fetch timestamp) to a JSON string using `JSON.stringify(storyObject, null, 2)` for readability.
- Write the JSON string to the file using `fs.writeFileSync()`. Use a `try...catch` block for error handling.
- Log (using the logger) the successful persistence of each story's data file or any errors encountered during file writing.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory (e.g., `./output/YYYY-MM-DD/`) contains exactly 10 files named `{storyId}_data.json`.
- AC2: Each JSON file contains valid JSON representing a single story object, including its metadata, fetch timestamp, and an array of its fetched comments, matching the defined structure.
- AC3: The number of comments in each file's `comments` array does not exceed `MAX_COMMENTS_PER_STORY`.
- AC4: Logs indicate that saving data to a file was attempted for each story, reporting success or specific file writing errors.
---
### Story 2.4: Implement Stage Testing Utility for HN Fetching
- **User Story / Goal:** As a developer, I want a separate, executable script that *only* performs the HN data fetching and persistence, so I can test and trigger this stage independently of the full pipeline.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/fetch_hn_data.ts`.
- This script should perform the essential setup required for this stage: initialize logger, load configuration (`.env`), determine and create output directory (reuse or replicate logic from Epic 1 / `src/index.ts`).
- The script should then execute the core logic of fetching stories via `algoliaHNClient.fetchTopStories`, fetching comments via `algoliaHNClient.fetchCommentsForStory` (using loaded config for limit), and persisting the results to JSON files using `fs.writeFileSync` (replicating logic from Story 2.3).
- The script should log its progress using the logger utility.
- Add a new script command to `package.json` under `"scripts"`: `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/fetch_hn_data.ts` exists.
- AC2: The script `stage:fetch` is defined in `package.json`'s `scripts` section.
- AC3: Running `npm run stage:fetch` executes successfully, performing only the setup, fetch, and persist steps.
- AC4: Running `npm run stage:fetch` creates the same 10 `{storyId}_data.json` files in the correct date-stamped output directory as running the main `npm run dev` command (at the current state of development).
- AC5: Logs generated by `npm run stage:fetch` reflect only the fetching and persisting steps, not subsequent pipeline stages.

# Epic 3 File
# Epic 3: Article Scraping & Persistence
**Goal:** Implement a best-effort article scraping mechanism to fetch and extract plain text content from the external URLs associated with fetched HN stories. Handle failures gracefully and persist successfully scraped text locally. Implement a stage testing utility for scraping.
## Story List
### Story 3.1: Implement Basic Article Scraper Module
- **User Story / Goal:** As a developer, I want a module that attempts to fetch HTML from a URL and extract the main article text using basic methods, handling common failures gracefully, so article content can be prepared for summarization.
- **Detailed Requirements:**
- Create a new module: `src/scraper/articleScraper.ts`.
- Add a suitable HTML parsing/extraction library dependency (e.g., `@extractus/article-extractor` recommended for simplicity, or `cheerio` for more control). Run `npm install @extractus/article-extractor --save-prod` (or chosen alternative).
- Implement an async function `scrapeArticle(url: string): Promise<string | null>` within the module.
- Inside the function:
- Use native `Workspace` to retrieve content from the `url`. Set a reasonable timeout (e.g., 10-15 seconds). Include a `User-Agent` header to mimic a browser.
- Handle potential `Workspace` errors (network errors, timeouts) using `try...catch`.
- Check the `response.ok` status. If not okay, log error and return `null`.
- Check the `Content-Type` header of the response. If it doesn't indicate HTML (e.g., does not include `text/html`), log warning and return `null`.
- If HTML is received, attempt to extract the main article text using the chosen library (`article-extractor` preferred).
- Wrap the extraction logic in a `try...catch` to handle library-specific errors.
- Return the extracted plain text string if successful. Ensure it's just text, not HTML markup.
- Return `null` if extraction fails or results in empty content.
- Log all significant events, errors, or reasons for returning null (e.g., "Scraping URL...", "Fetch failed:", "Non-HTML content type:", "Extraction failed:", "Successfully extracted text") using the logger utility.
- Define TypeScript types/interfaces as needed.
- **Acceptance Criteria (ACs):**
- AC1: The `articleScraper.ts` module exists and exports the `scrapeArticle` function.
- AC2: The chosen scraping library (e.g., `@extractus/article-extractor`) is added to `dependencies` in `package.json`.
- AC3: `scrapeArticle` uses native `Workspace` with a timeout and User-Agent header.
- AC4: `scrapeArticle` correctly handles fetch errors, non-OK responses, and non-HTML content types by logging and returning `null`.
- AC5: `scrapeArticle` uses the chosen library to attempt text extraction from valid HTML content.
- AC6: `scrapeArticle` returns the extracted plain text on success, and `null` on any failure (fetch, non-HTML, extraction error, empty result).
- AC7: Relevant logs are produced for success, failure modes, and errors encountered during the process.
---
### Story 3.2: Integrate Article Scraping into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the article scraper into the main workflow (`src/index.ts`), attempting to scrape the article for each HN story that has a valid URL, after fetching its data.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import the `scrapeArticle` function from `src/scraper/articleScraper.ts`.
- Within the main loop iterating through the fetched stories (after comments are fetched in Epic 2):
- Check if `story.url` exists and appears to be a valid HTTP/HTTPS URL. A simple check for starting with `http://` or `https://` is sufficient.
- If the URL is missing or invalid, log a warning ("Skipping scraping for story {storyId}: Missing or invalid URL") and proceed to the next story's processing step.
- If a valid URL exists, log ("Attempting to scrape article for story {storyId} from {story.url}").
- Call `await scrapeArticle(story.url)`.
- Store the result (the extracted text string or `null`) in memory, associated with the story object (e.g., add property `articleContent: string | null`).
- Log the outcome clearly (e.g., "Successfully scraped article for story {storyId}", "Failed to scrape article for story {storyId}").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 & 2 steps, and then attempts article scraping for stories with valid URLs.
- AC2: Stories with missing or invalid URLs are skipped, and a corresponding log message is generated.
- AC3: For stories with valid URLs, the `scrapeArticle` function is called.
- AC4: Logs clearly indicate the start and success/failure outcome of the scraping attempt for each relevant story.
- AC5: Story objects held in memory after this stage contain an `articleContent` property holding the scraped text (string) or `null` if scraping was skipped or failed.
---
### Story 3.3: Persist Scraped Article Text Locally
- **User Story / Goal:** As a developer, I want to save successfully scraped article text to a separate local file for each story, so that the text content is available as input for the summarization stage.
- **Detailed Requirements:**
- Import Node.js `fs` and `path` modules if not already present in `src/index.ts`.
- In the main workflow (`src/index.ts`), immediately after a successful call to `scrapeArticle` for a story (where the result is a non-null string):
- Retrieve the full path to the current date-stamped output directory.
- Construct the filename: `{storyId}_article.txt`.
- Construct the full file path using `path.join()`.
- Get the successfully scraped article text string (`articleContent`).
- Use `fs.writeFileSync(fullPath, articleContent, 'utf-8')` to save the text to the file. Wrap in `try...catch` for file system errors.
- Log the successful saving of the file (e.g., "Saved scraped article text to {filename}") or any file writing errors encountered.
- Ensure *no* `_article.txt` file is created if `scrapeArticle` returned `null` (due to skipping or failure).
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains `_article.txt` files *only* for those stories where `scrapeArticle` succeeded and returned text content.
- AC2: The name of each article text file is `{storyId}_article.txt`.
- AC3: The content of each `_article.txt` file is the plain text string returned by `scrapeArticle`.
- AC4: Logs confirm the successful writing of each `_article.txt` file or report specific file writing errors.
- AC5: No empty `_article.txt` files are created. Files only exist if scraping was successful.
---
### Story 3.4: Implement Stage Testing Utility for Scraping
- **User Story / Goal:** As a developer, I want a separate script/command to test the article scraping logic using HN story data from local files, allowing independent testing and debugging of the scraper.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/scrape_articles.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `scrapeArticle`.
- The script should:
- Initialize the logger.
- Load configuration (to get `OUTPUT_DIR_PATH`).
- Determine the target date-stamped directory path (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`, using the current date or potentially an optional CLI argument). Ensure this directory exists.
- Read the directory contents and identify all `{storyId}_data.json` files.
- For each `_data.json` file found:
- Read and parse the JSON content.
- Extract the `storyId` and `url`.
- If a valid `url` exists, call `await scrapeArticle(url)`.
- If scraping succeeds (returns text), save the text to `{storyId}_article.txt` in the same directory (using logic from Story 3.3). Overwrite if the file exists.
- Log the progress and outcome (skip/success/fail) for each story processed.
- Add a new script command to `package.json`: `"stage:scrape": "ts-node src/stages/scrape_articles.ts"`. Consider adding argument parsing later if needed to specify a date/directory.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/scrape_articles.ts` exists.
- AC2: The script `stage:scrape` is defined in `package.json`.
- AC3: Running `npm run stage:scrape` (assuming a directory with `_data.json` files exists from a previous `stage:fetch` run) reads these files.
- AC4: The script calls `scrapeArticle` for stories with valid URLs found in the JSON files.
- AC5: The script creates/updates `{storyId}_article.txt` files in the target directory corresponding to successfully scraped articles.
- AC6: The script logs its actions (reading files, attempting scraping, saving results) for each story ID processed.
- AC7: The script operates solely based on local `_data.json` files and fetching from external article URLs; it does not call the Algolia HN API.

- **Prerequisite:** Ensure a local Ollama instance is installed and running, accessible via the URL defined in `.env` (`OLLAMA_ENDPOINT_URL`), and that the model specified in `.env` (`OLLAMA_MODEL`) has been downloaded (e.g., via `ollama pull model_name`). Instructions for this setup should be in the project README.
- Create a new module: `src/clients/ollamaClient.ts`.
- Implement an async function `generateSummary(promptTemplate: string, content: string): Promise<string | null>`. *(Note: Parameter name changed for clarity)*
- Add configuration variables `OLLAMA_ENDPOINT_URL` (e.g., `http://localhost:11434`) and `OLLAMA_MODEL` (e.g., `llama3`) to `.env.example`. Ensure they are loaded via the config module (`src/utils/config.ts`). Update local `.env` with actual values. Add optional `OLLAMA_TIMEOUT_MS` to `.env.example` with a default like `120000`.
- Inside `generateSummary`:
- Construct the full prompt string using the `promptTemplate` and the provided `content` (e.g., replacing a placeholder like `{Content Placeholder}` in the template, or simple concatenation if templates are basic).
- Construct the Ollama API request payload (JSON): `{ model: configured_model, prompt: full_prompt, stream: false }`. Refer to Ollama `/api/generate` documentation and `docs/data-models.md`.
- Use native `Workspace` to send a POST request to the configured Ollama endpoint + `/api/generate`. Set appropriate headers (`Content-Type: application/json`). Use the configured `OLLAMA_TIMEOUT_MS` or a reasonable default (e.g., 2 minutes).
- Handle `Workspace` errors (network, timeout) using `try...catch`.
- Check `response.ok`. If not OK, log the status/error and return `null`.
- Parse the JSON response from Ollama. Extract the generated text (typically in the `response` field). Refer to `docs/data-models.md`.
- Check for potential errors within the Ollama response structure itself (e.g., an `error` field).
- Return the extracted summary string on success. Return `null` on any failure.
- Log key events: initiating request (mention model), receiving response, success, failure reasons, potentially request/response time using the logger.
- Define necessary TypeScript types for the Ollama request payload and expected response structure in `src/types/ollama.ts` (referenced in `docs/data-models.md`).
- **Acceptance Criteria (ACs):**
- AC1: The `ollamaClient.ts` module exists and exports `generateSummary`.
- AC2: `OLLAMA_ENDPOINT_URL` and `OLLAMA_MODEL` are defined in `.env.example`, loaded via config, and used by the client. Optional `OLLAMA_TIMEOUT_MS` is handled.
- AC3: `generateSummary` sends a correctly formatted POST request (model, full prompt based on template and content, stream:false) to the configured Ollama endpoint/path using native `Workspace`.
- AC4: Network errors, timeouts, and non-OK API responses are handled gracefully, logged, and result in a `null` return (given the Prerequisite Ollama service is running).
- AC5: A successful Ollama response is parsed correctly, the generated text is extracted, and returned as a string.
* AC6: Unexpected Ollama response formats or internal errors (e.g., `{"error": "..."}`) are handled, logged, and result in a `null` return.
* AC7: Logs provide visibility into the client's interaction with the Ollama API.

### Story 4.2: Define Summarization Prompts
* **User Story / Goal:** As a developer, I want standardized base prompts for generating article summaries and HN discussion summaries documented centrally, ensuring consistent instructions are sent to the LLM.
* **Detailed Requirements:**
* Define two standardized base prompts (`ARTICLE_SUMMARY_PROMPT`, `DISCUSSION_SUMMARY_PROMPT`) **and document them in `docs/prompts.md`**.
* Ensure these prompts are accessible within the application code, for example, by defining them as exported constants in a dedicated module like `src/utils/prompts.ts`, which reads from or mirrors the content in `docs/prompts.md`.
* **Acceptance Criteria (ACs):**
* AC1: The `ARTICLE_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC2: The `DISCUSSION_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC3: The prompt texts documented in `docs/prompts.md` are available as constants or variables within the application code (e.g., via `src/utils/prompts.ts`) for use by the Ollama client integration.
---
### Story 4.3: Integrate Summarization into Main Workflow
* **User Story / Goal:** As a developer, I want to integrate the Ollama client into the main workflow to generate summaries for each story's scraped article text (if available) and fetched comments, using centrally defined prompts and handling potential comment length limits.
* **Detailed Requirements:**
* Modify the main execution flow in `src/index.ts` or `src/core/pipeline.ts`.
* Import `ollamaClient.generateSummary` and the prompt constants/variables (e.g., from `src/utils/prompts.ts`, which reflect `docs/prompts.md`).
* Load the optional `MAX_COMMENT_CHARS_FOR_SUMMARY` configuration value from `.env` via the config utility.
* Within the main loop iterating through stories (after article scraping/persistence in Epic 3):
* **Article Summary Generation:**
* Check if the `story` object has non-null `articleContent`.
* If yes: log "Attempting article summarization for story {storyId}", call `await generateSummary(ARTICLE_SUMMARY_PROMPT, story.articleContent)`, store the result (string or null) as `story.articleSummary`, log success/failure.
* If no: set `story.articleSummary = null`, log "Skipping article summarization: No content".
* **Discussion Summary Generation:**
* Check if the `story` object has a non-empty `comments` array.
* If yes:
* Format the `story.comments` array into a single text block suitable for the LLM prompt (e.g., concatenating `comment.text` with separators like `---`).
* **Check truncation limit:** If `MAX_COMMENT_CHARS_FOR_SUMMARY` is configured to a positive number and the `formattedCommentsText` length exceeds it, truncate `formattedCommentsText` to the limit and log a warning: "Comment text truncated to {limit} characters for summarization for story {storyId}".
* Log "Attempting discussion summarization for story {storyId}".
* Call `await generateSummary(DISCUSSION_SUMMARY_PROMPT, formattedCommentsText)`. *(Pass the potentially truncated text)*
* Store the result (string or null) as `story.discussionSummary`. Log success/failure.
* If no: set `story.discussionSummary = null`, log "Skipping discussion summarization: No comments".
* **Acceptance Criteria (ACs):**
* AC1: Running `npm run dev` executes steps from Epics 1-3, then attempts summarization using the Ollama client.
* AC2: Article summary is attempted only if `articleContent` exists for a story.
* AC3: Discussion summary is attempted only if `comments` exist for a story.
* AC4: `generateSummary` is called with the correct prompts (sourced consistently with `docs/prompts.md`) and corresponding content (article text or formatted/potentially truncated comments).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and comment text exceeds it, the text passed to `generateSummary` is truncated, and a warning is logged.
* AC6: Logs clearly indicate the start, success, or failure (including null returns from the client) for both article and discussion summarization attempts per story.
* AC7: Story objects in memory now contain `articleSummary` (string/null) and `discussionSummary` (string/null) properties.
---
### Story 4.4: Persist Generated Summaries Locally
*(No changes needed for this story based on recent decisions)*
- **User Story / Goal:** As a developer, I want to save the generated article and discussion summaries (or null placeholders) to a local JSON file for each story, making them available for the email assembly stage.
- **Detailed Requirements:**
- Define the structure for the summary output file: `{storyId}_summary.json`. Content example: `{ "storyId": "...", "articleSummary": "...", "discussionSummary": "...", "summarizedAt": "ISO_TIMESTAMP" }`. Note that `articleSummary` and `discussionSummary` can be `null`.
- Import `fs` and `path` in `src/index.ts` or `src/core/pipeline.ts` if needed.
- In the main workflow loop, after *both* summarization attempts (article and discussion) for a story are complete:
- Create a summary result object containing `storyId`, `articleSummary` (string or null), `discussionSummary` (string or null), and the current ISO timestamp (`new Date().toISOString()`). Add this timestamp to the in-memory `story` object as well (`story.summarizedAt`).
- Get the full path to the date-stamped output directory.
- Construct the filename: `{storyId}_summary.json`.
- Construct the full file path using `path.join()`.
- Serialize the summary result object to JSON (`JSON.stringify(..., null, 2)`).
- Use `fs.writeFileSync` to save the JSON to the file, wrapping in `try...catch`.
- Log the successful saving of the summary file or any file writing errors.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains 10 files named `{storyId}_summary.json`.
- AC2: Each `_summary.json` file contains valid JSON adhering to the defined structure.
- AC3: The `articleSummary` field contains the generated summary string if successful, otherwise `null`.
- AC4: The `discussionSummary` field contains the generated summary string if successful, otherwise `null`.
- AC5: A valid ISO timestamp is present in the `summarizedAt` field.
- AC6: Logs confirm successful writing of each summary file or report file system errors.
---
### Story 4.5: Implement Stage Testing Utility for Summarization
*(Changes needed to reflect prompt sourcing and optional truncation)*
* **User Story / Goal:** As a developer, I want a separate script/command to test the LLM summarization logic using locally persisted data (HN comments, scraped article text), allowing independent testing of prompts and Ollama interaction.
* **Detailed Requirements:**
* Create a new standalone script file: `src/stages/summarize_content.ts`.
* Import necessary modules: `fs`, `path`, `logger`, `config`, `ollamaClient`, prompt constants (e.g., from `src/utils/prompts.ts`).
* The script should:
* Initialize logger, load configuration (Ollama endpoint/model, output dir, **optional `MAX_COMMENT_CHARS_FOR_SUMMARY`**).
* Determine target date-stamped directory path.
* Find all `{storyId}_data.json` files in the directory.
* For each `storyId` found:
* Read `{storyId}_data.json` to get comments. Format them into a single text block.
* *Attempt* to read `{storyId}_article.txt`. Handle file-not-found gracefully. Store content or null.
* Call `ollamaClient.generateSummary` for article text (if not null) using `ARTICLE_SUMMARY_PROMPT`.
* **Apply truncation logic:** If comments exist, check `MAX_COMMENT_CHARS_FOR_SUMMARY` and truncate the formatted comment text block if needed, logging a warning.
* Call `ollamaClient.generateSummary` for formatted comments (if comments exist) using `DISCUSSION_SUMMARY_PROMPT` *(passing potentially truncated text)*.
* Construct the summary result object (with summaries or nulls, and timestamp).
* Save the result object to `{storyId}_summary.json` in the same directory (using logic from Story 4.4), overwriting if exists.
* Log progress (reading files, calling Ollama, truncation warnings, saving results) for each story ID.
* Add script to `package.json`: `"stage:summarize": "ts-node src/stages/summarize_content.ts"`.
* **Acceptance Criteria (ACs):**
* AC1: The file `src/stages/summarize_content.ts` exists.
* AC2: The script `stage:summarize` is defined in `package.json`.
* AC3: Running `npm run stage:summarize` (after `stage:fetch` and `stage:scrape` runs) reads `_data.json` and attempts to read `_article.txt` files from the target directory.
* AC4: The script calls the `ollamaClient` with correct prompts (sourced consistently with `docs/prompts.md`) and content derived *only* from the local files (requires Ollama service running per Story 4.1 prerequisite).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and applicable, comment text is truncated before calling the client, and a warning is logged.
* AC6: The script creates/updates `{storyId}_summary.json` files in the target directory reflecting the results of the Ollama calls (summaries or nulls).
* AC7: Logs show the script processing each story ID found locally, interacting with Ollama, and saving results.
* AC8: The script does not call Algolia API or the article scraper module.

# Epic 5: Digest Assembly & Email Dispatch
**Goal:** Assemble the collected story data and summaries from local files, format them into a readable HTML email digest, and send the email using Nodemailer with configured credentials. Implement a stage testing utility for emailing with a dry-run option.
## Story List
### Story 5.1: Implement Email Content Assembler
- **User Story / Goal:** As a developer, I want a module that reads the persisted story metadata (`_data.json`) and summaries (`_summary.json`) from a specified directory, consolidating the necessary information needed to render the email digest.
- **Detailed Requirements:**
- Create a new module: `src/email/contentAssembler.ts`.
- Define a TypeScript type/interface `DigestData` representing the data needed per story for the email template: `{ storyId: string, title: string, hnUrl: string, articleUrl: string | null, articleSummary: string | null, discussionSummary: string | null }`.
- Implement an async function `assembleDigestData(dateDirPath: string): Promise<DigestData[]>`.
- The function should:
- Use Node.js `fs` to read the contents of the `dateDirPath`.
- Identify all files matching the pattern `{storyId}_data.json`.
- For each `storyId` found:
- Read and parse the `{storyId}_data.json` file. Extract `title`, `hnUrl`, and `url` (use as `articleUrl`). Handle potential file read/parse errors gracefully (log and skip story).
- Attempt to read and parse the corresponding `{storyId}_summary.json` file. Handle file-not-found or parse errors gracefully (treat `articleSummary` and `discussionSummary` as `null`).
- Construct a `DigestData` object for the story, including the extracted metadata and summaries (or nulls).
- Collect all successfully constructed `DigestData` objects into an array.
- Return the array. It should ideally contain 10 items if all previous stages succeeded.
- Log progress (e.g., "Assembling digest data from directory...", "Processing story {storyId}...") and any errors encountered during file processing using the logger.
- **Acceptance Criteria (ACs):**
- AC1: The `contentAssembler.ts` module exists and exports `assembleDigestData` and the `DigestData` type.
- AC2: `assembleDigestData` correctly reads `_data.json` files from the provided directory path.
- AC3: It attempts to read corresponding `_summary.json` files, correctly handling cases where the summary file might be missing or unparseable (resulting in null summaries for that story).
- AC4: The function returns a promise resolving to an array of `DigestData` objects, populated with data extracted from the files.
- AC5: Errors during file reading or JSON parsing are logged, and the function returns data for successfully processed stories.
---
### Story 5.2: Create HTML Email Template & Renderer
- **User Story / Goal:** As a developer, I want a basic HTML email template and a function to render it with the assembled digest data, producing the final HTML content for the email body.
- **Detailed Requirements:**
- Define the HTML structure. This can be done using template literals within a function or potentially using a simple template file (e.g., `src/email/templates/digestTemplate.html`) and `fs.readFileSync`. Template literals are simpler for MVP.
- Create a function `renderDigestHtml(data: DigestData[], digestDate: string): string` (e.g., in `src/email/contentAssembler.ts` or a new `templater.ts`).
- The function should generate an HTML string with:
- A suitable title in the body (e.g., `<h1>Hacker News Top 10 Summaries for ${digestDate}</h1>`).
- A loop through the `data` array.
- For each `story` in `data`:
- Display `<h2><a href="${story.articleUrl || story.hnUrl}">${story.title}</a></h2>`.
- Display `<p><a href="${story.hnUrl}">View HN Discussion</a></p>`.
- Conditionally display `<h3>Article Summary</h3><p>${story.articleSummary}</p>` *only if* `story.articleSummary` is not null/empty.
- Conditionally display `<h3>Discussion Summary</h3><p>${story.discussionSummary}</p>` *only if* `story.discussionSummary` is not null/empty.
- Include a separator (e.g., `<hr style="margin-top: 20px; margin-bottom: 20px;">`).
- Use basic inline CSS for minimal styling (margins, etc.) to ensure readability. Avoid complex layouts.
- Return the complete HTML document as a string.
- **Acceptance Criteria (ACs):**
- AC1: A function `renderDigestHtml` exists that accepts the digest data array and a date string.
- AC2: The function returns a single, complete HTML string.
- AC3: The generated HTML includes a title with the date and correctly iterates through the story data.
- AC4: For each story, the HTML displays the linked title, HN link, and conditionally displays the article and discussion summaries with headings.
- AC5: Basic separators and margins are used for readability. The HTML is simple and likely to render reasonably in most email clients.
---
### Story 5.3: Implement Nodemailer Email Sender
- **User Story / Goal:** As a developer, I want a module to send the generated HTML email using Nodemailer, configured with credentials stored securely in the environment file.
- **Detailed Requirements:**
- Add Nodemailer dependencies: `npm install nodemailer @types/nodemailer --save-prod`.
- Add required configuration variables to `.env.example` (and local `.env`): `EMAIL_HOST`, `EMAIL_PORT` (e.g., 587), `EMAIL_SECURE` (e.g., `false` for STARTTLS on 587, `true` for 465), `EMAIL_USER`, `EMAIL_PASS`, `EMAIL_FROM` (e.g., `"Your Name <you@example.com>"`), `EMAIL_RECIPIENTS` (comma-separated list).
- Create a new module: `src/email/emailSender.ts`.
- Implement an async function `sendDigestEmail(subject: string, htmlContent: string): Promise<boolean>`.
- Inside the function:
- Load the `EMAIL_*` variables from the config module.
- Create a Nodemailer transporter using `nodemailer.createTransport` with the loaded config (host, port, secure flag, auth: { user, pass }).
- Verify transporter configuration using `transporter.verify()` (optional but recommended). Log verification success/failure.
- Parse the `EMAIL_RECIPIENTS` string into an array or comma-separated string suitable for the `to` field.
- Define the `mailOptions`: `{ from: EMAIL_FROM, to: parsedRecipients, subject: subject, html: htmlContent }`.
- Call `await transporter.sendMail(mailOptions)`.
- If `sendMail` succeeds, log the success message including the `messageId` from the result. Return `true`.
- If `sendMail` fails (throws error), log the error using the logger. Return `false`.
- **Acceptance Criteria (ACs):**
- AC1: `nodemailer` and `@types/nodemailer` dependencies are added.
- AC2: `EMAIL_*` variables are defined in `.env.example` and loaded from config.
- AC3: `emailSender.ts` module exists and exports `sendDigestEmail`.
- AC4: `sendDigestEmail` correctly creates a Nodemailer transporter using configuration from `.env`. Transporter verification is attempted (optional AC).
- AC5: The `to` field is correctly populated based on `EMAIL_RECIPIENTS`.
- AC6: `transporter.sendMail` is called with correct `from`, `to`, `subject`, and `html` options.
- AC7: Email sending success (including message ID) or failure is logged clearly.
- AC8: The function returns `true` on successful sending, `false` otherwise.
---
### Story 5.4: Integrate Email Assembly and Sending into Main Workflow
- **User Story / Goal:** As a developer, I want the main application workflow (`src/index.ts`) to orchestrate the final steps: assembling digest data, rendering the HTML, and triggering the email send after all previous stages are complete.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`.
- Execute these steps *after* the main loop (where stories are fetched, scraped, summarized, and persisted) completes:
- Log "Starting final digest assembly and email dispatch...".
- Determine the path to the current date-stamped output directory.
- Call `const digestData = await assembleDigestData(dateDirPath)`.
- Check if `digestData` array is not empty.
- If yes:
- Get the current date string (e.g., 'YYYY-MM-DD').
- `const htmlContent = renderDigestHtml(digestData, currentDate)`.
- `const subject = \`BMad Hacker Daily Digest - ${currentDate}\``.
- `const emailSent = await sendDigestEmail(subject, htmlContent)`.
- Log the final outcome based on `emailSent` ("Digest email sent successfully." or "Failed to send digest email.").
- If no (`digestData` is empty or assembly failed):
- Log an error: "Failed to assemble digest data or no data found. Skipping email."
- Log "BMad Hacker Daily Digest process finished."
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes all stages (Epics 1-4) and then proceeds to email assembly and sending.
- AC2: `assembleDigestData` is called correctly with the output directory path after other processing is done.
- AC3: If data is assembled, `renderDigestHtml` and `sendDigestEmail` are called with the correct data, subject, and HTML.
- AC4: The final success or failure of the email sending step is logged.
- AC5: If `assembleDigestData` returns no data, email sending is skipped, and an appropriate message is logged.
- AC6: The application logs a final completion message.
---
### Story 5.5: Implement Stage Testing Utility for Emailing
- **User Story / Goal:** As a developer, I want a separate script/command to test the email assembly, rendering, and sending logic using persisted local data, including a crucial `--dry-run` option to prevent accidental email sending during tests.
- **Detailed Requirements:**
- Add `yargs` dependency for argument parsing: `npm install yargs @types/yargs --save-dev`.
- Create a new standalone script file: `src/stages/send_digest.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`, `yargs`.
- Use `yargs` to parse command-line arguments, specifically looking for a `--dry-run` boolean flag (defaulting to `false`). Allow an optional argument for specifying the date-stamped directory, otherwise default to current date.
- The script should:
- Initialize logger, load config.
- Determine the target date-stamped directory path (from arg or default). Log the target directory.
- Call `await assembleDigestData(dateDirPath)`.
- If data is assembled and not empty:
- Determine the date string for the subject/title.
- Call `renderDigestHtml(digestData, dateString)` to get HTML.
- Construct the subject string.
- Check the `dryRun` flag:
- If `true`: Log "DRY RUN enabled. Skipping actual email send.". Log the subject. Save the `htmlContent` to a file in the target directory (e.g., `_digest_preview.html`). Log that the preview file was saved.
- If `false`: Log "Live run: Attempting to send email...". Call `await sendDigestEmail(subject, htmlContent)`. Log success/failure based on the return value.
- If data assembly fails or is empty, log the error.
- Add script to `package.json`: `"stage:email": "ts-node src/stages/send_digest.ts --"`. The `--` allows passing arguments like `--dry-run`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/send_digest.ts` exists. `yargs` dependency is added.
- AC2: The script `stage:email` is defined in `package.json` allowing arguments.
- AC3: Running `npm run stage:email -- --dry-run` reads local data, renders HTML, logs the intent, saves `_digest_preview.html` locally, and does *not* call `sendDigestEmail`.
- AC4: Running `npm run stage:email` (without `--dry-run`) reads local data, renders HTML, and *does* call `sendDigestEmail`, logging the outcome.
- AC5: The script correctly identifies and acts upon the `--dry-run` flag.
- AC6: Logs clearly distinguish between dry runs and live runs and report success/failure.
- AC7: The script operates using only local files and the email configuration/service; it does not invoke prior pipeline stages (Algolia, scraping, Ollama).

# Epic 1: Project Initialization & Core Setup
**Goal:** Initialize the project using the "bmad-boilerplate", manage dependencies, setup `.env` and config loading, establish basic CLI entry point, setup basic logging and output directory structure. This provides the foundational setup for all subsequent development work.
## Story List
### Story 1.1: Initialize Project from Boilerplate
- **User Story / Goal:** As a developer, I want to set up the initial project structure using the `bmad-boilerplate`, so that I have the standard tooling (TS, Jest, ESLint, Prettier), configurations, and scripts in place.
- **Detailed Requirements:**
- Copy or clone the contents of the `bmad-boilerplate` into the new project's root directory.
- Initialize a git repository in the project root directory (if not already done by cloning).
- Ensure the `.gitignore` file from the boilerplate is present.
- Run `npm install` to download and install all `devDependencies` specified in the boilerplate's `package.json`.
- Verify that the core boilerplate scripts (`lint`, `format`, `test`, `build`) execute without errors on the initial codebase.
- **Acceptance Criteria (ACs):**
- AC1: The project directory contains the files and structure from `bmad-boilerplate`.
- AC2: A `node_modules` directory exists and contains packages corresponding to `devDependencies`.
- AC3: `npm run lint` command completes successfully without reporting any linting errors.
- AC4: `npm run format` command completes successfully, potentially making formatting changes according to Prettier rules. Running it a second time should result in no changes.
- AC5: `npm run test` command executes Jest successfully (it may report "no tests found" which is acceptable at this stage).
- AC6: `npm run build` command executes successfully, creating a `dist` directory containing compiled JavaScript output.
- AC7: The `.gitignore` file exists and includes entries for `node_modules/`, `.env`, `dist/`, etc. as specified in the boilerplate.
---
### Story 1.2: Setup Environment Configuration
- **User Story / Goal:** As a developer, I want to establish the environment configuration mechanism using `.env` files, so that secrets and settings (like output paths) can be managed outside of version control, following boilerplate conventions.
- **Detailed Requirements:**
- Add a production dependency for loading `.env` files (e.g., `dotenv`). Run `npm install dotenv --save-prod` (or similar library).
- Verify the `.env.example` file exists (from boilerplate).
- Add an initial configuration variable `OUTPUT_DIR_PATH=./output` to `.env.example`.
- Create the `.env` file locally by copying `.env.example`. Populate `OUTPUT_DIR_PATH` if needed (can keep default).
- Implement a utility module (e.g., `src/config.ts`) that loads environment variables from the `.env` file at application startup.
- The utility should export the loaded configuration values (initially just `OUTPUT_DIR_PATH`).
- Ensure the `.env` file is listed in `.gitignore` and is not committed.
- **Acceptance Criteria (ACs):**
- AC1: The chosen `.env` library (e.g., `dotenv`) is listed under `dependencies` in `package.json` and `package-lock.json` is updated.
- AC2: The `.env.example` file exists, is tracked by git, and contains the line `OUTPUT_DIR_PATH=./output`.
- AC3: The `.env` file exists locally but is NOT tracked by git.
- AC4: A configuration module (`src/config.ts` or similar) exists and successfully loads the `OUTPUT_DIR_PATH` value from `.env` when the application starts.
- AC5: The loaded `OUTPUT_DIR_PATH` value is accessible within the application code.
---
### Story 1.3: Implement Basic CLI Entry Point & Execution
- **User Story / Goal:** As a developer, I want a basic `src/index.ts` entry point that can be executed via the boilerplate's `dev` and `start` scripts, providing a working foundation for the application logic.
- **Detailed Requirements:**
- Create the main application entry point file at `src/index.ts`.
- Implement minimal code within `src/index.ts` to:
- Import the configuration loading mechanism (from Story 1.2).
- Log a simple startup message to the console (e.g., "BMad Hacker Daily Digest - Starting Up...").
- (Optional) Log the loaded `OUTPUT_DIR_PATH` to verify config loading.
- Confirm execution using boilerplate scripts.
- **Acceptance Criteria (ACs):**
- AC1: The `src/index.ts` file exists.
- AC2: Running `npm run dev` executes `src/index.ts` via `ts-node` and logs the startup message to the console.
- AC3: Running `npm run build` successfully compiles `src/index.ts` (and any imports) into the `dist` directory.
- AC4: Running `npm start` (after a successful build) executes the compiled code from `dist` and logs the startup message to the console.
---
### Story 1.4: Setup Basic Logging and Output Directory
- **User Story / Goal:** As a developer, I want a basic console logging mechanism and the dynamic creation of a date-stamped output directory, so that the application can provide execution feedback and prepare for storing data artifacts in subsequent epics.
- **Detailed Requirements:**
- Implement a simple, reusable logging utility module (e.g., `src/logger.ts`). Initially, it can wrap `console.log`, `console.warn`, `console.error`.
- Refactor `src/index.ts` to use this `logger` for its startup message(s).
- In `src/index.ts` (or a setup function called by it):
- Retrieve the `OUTPUT_DIR_PATH` from the configuration (loaded in Story 1.2).
- Determine the current date in 'YYYY-MM-DD' format.
- Construct the full path for the date-stamped subdirectory (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`).
- Check if the base output directory exists; if not, create it.
- Check if the date-stamped subdirectory exists; if not, create it recursively. Use Node.js `fs` module (e.g., `fs.mkdirSync(path, { recursive: true })`).
- Log (using the logger) the full path of the output directory being used for the current run (e.g., "Output directory for this run: ./output/2025-05-04").
- **Acceptance Criteria (ACs):**
- AC1: A logger utility module (`src/logger.ts` or similar) exists and is used for console output in `src/index.ts`.
- AC2: Running `npm run dev` or `npm start` logs the startup message via the logger.
- AC3: Running the application creates the base output directory (e.g., `./output` defined in `.env`) if it doesn't already exist.
- AC4: Running the application creates a date-stamped subdirectory (e.g., `./output/2025-05-04`) within the base output directory if it doesn't already exist.
- AC5: The application logs a message indicating the full path to the date-stamped output directory created/used for the current execution.
- AC6: The application exits gracefully after performing these setup steps (for now).

# Epic 2: HN Data Acquisition & Persistence
**Goal:** Implement fetching top 10 stories and their comments (respecting limits) from Algolia HN API, and persist this raw data locally into the date-stamped output directory created in Epic 1. Implement a stage testing utility for fetching.
## Story List
### Story 2.1: Implement Algolia HN API Client
- **User Story / Goal:** As a developer, I want a dedicated client module to interact with the Algolia Hacker News Search API, so that fetching stories and comments is encapsulated, reusable, and uses the required native `Workspace` API.
- **Detailed Requirements:**
- Create a new module: `src/clients/algoliaHNClient.ts`.
- Implement an async function `WorkspaceTopStories` within the client:
- Use native `Workspace` to call the Algolia HN Search API endpoint for front-page stories (e.g., `http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10`). Adjust `hitsPerPage` if needed to ensure 10 stories.
- Parse the JSON response.
- Extract required metadata for each story: `objectID` (use as `storyId`), `title`, `url` (article URL), `points`, `num_comments`. Handle potential missing `url` field gracefully (log warning, maybe skip story later if URL needed).
- Construct the `hnUrl` for each story (e.g., `https://news.ycombinator.com/item?id={storyId}`).
- Return an array of structured story objects.
- Implement a separate async function `WorkspaceCommentsForStory` within the client:
- Accept `storyId` and `maxComments` limit as arguments.
- Use native `Workspace` to call the Algolia HN Search API endpoint for comments of a specific story (e.g., `http://hn.algolia.com/api/v1/search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`).
- Parse the JSON response.
- Extract required comment data: `objectID` (use as `commentId`), `comment_text`, `author`, `created_at`.
- Filter out comments where `comment_text` is null or empty. Ensure only up to `maxComments` are returned.
- Return an array of structured comment objects.
- Implement basic error handling using `try...catch` around `Workspace` calls and check `response.ok` status. Log errors using the logger utility from Epic 1.
- Define TypeScript interfaces/types for the expected structures of API responses (stories, comments) and the data returned by the client functions (e.g., `Story`, `Comment`).
- **Acceptance Criteria (ACs):**
- AC1: The module `src/clients/algoliaHNClient.ts` exists and exports `WorkspaceTopStories` and `WorkspaceCommentsForStory` functions.
- AC2: Calling `WorkspaceTopStories` makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of 10 `Story` objects containing the specified metadata.
- AC3: Calling `WorkspaceCommentsForStory` with a valid `storyId` and `maxComments` limit makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of `Comment` objects (up to `maxComments`), filtering out empty ones.
- AC4: Both functions use the native `Workspace` API internally.
- AC5: Network errors or non-successful API responses (e.g., status 4xx, 5xx) are caught and logged using the logger.
- AC6: Relevant TypeScript types (`Story`, `Comment`, etc.) are defined and used within the client module.
---
### Story 2.2: Integrate HN Data Fetching into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the HN data fetching logic into the main application workflow (`src/index.ts`), so that running the app retrieves the top 10 stories and their comments after completing the setup from Epic 1.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts` (or a main async function called by it).
- Import the `algoliaHNClient` functions.
- Import the configuration module to access `MAX_COMMENTS_PER_STORY`.
- After the Epic 1 setup (config load, logger init, output dir creation), call `WorkspaceTopStories()`.
- Log the number of stories fetched.
- Iterate through the array of fetched `Story` objects.
- For each `Story`, call `WorkspaceCommentsForStory()`, passing the `story.storyId` and the configured `MAX_COMMENTS_PER_STORY`.
- Store the fetched comments within the corresponding `Story` object in memory (e.g., add a `comments: Comment[]` property to the `Story` object).
- Log progress using the logger utility (e.g., "Fetched 10 stories.", "Fetching up to X comments for story {storyId}...").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 setup steps followed by fetching stories and then comments for each story.
- AC2: Logs clearly show the start and successful completion of fetching stories, and the start of fetching comments for each of the 10 stories.
- AC3: The configured `MAX_COMMENTS_PER_STORY` value is read from config and used in the calls to `WorkspaceCommentsForStory`.
- AC4: After successful execution, story objects held in memory contain a nested array of fetched comment objects. (Can be verified via debugger or temporary logging).
---
### Story 2.3: Persist Fetched HN Data Locally
- **User Story / Goal:** As a developer, I want to save the fetched HN stories (including their comments) to JSON files in the date-stamped output directory, so that the raw data is persisted locally for subsequent pipeline stages and debugging.
- **Detailed Requirements:**
- Define a consistent JSON structure for the output file content. Example: `{ storyId: "...", title: "...", url: "...", hnUrl: "...", points: ..., fetchedAt: "ISO_TIMESTAMP", comments: [{ commentId: "...", text: "...", author: "...", createdAt: "ISO_TIMESTAMP", ... }, ...] }`. Include a timestamp for when the data was fetched.
- Import Node.js `fs` (specifically `fs.writeFileSync`) and `path` modules.
- In the main workflow (`src/index.ts`), within the loop iterating through stories (after comments have been fetched and added to the story object in Story 2.2):
- Get the full path to the date-stamped output directory (determined in Epic 1).
- Construct the filename for the story's data: `{storyId}_data.json`.
- Construct the full file path using `path.join()`.
- Serialize the complete story object (including comments and fetch timestamp) to a JSON string using `JSON.stringify(storyObject, null, 2)` for readability.
- Write the JSON string to the file using `fs.writeFileSync()`. Use a `try...catch` block for error handling.
- Log (using the logger) the successful persistence of each story's data file or any errors encountered during file writing.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory (e.g., `./output/YYYY-MM-DD/`) contains exactly 10 files named `{storyId}_data.json`.
- AC2: Each JSON file contains valid JSON representing a single story object, including its metadata, fetch timestamp, and an array of its fetched comments, matching the defined structure.
- AC3: The number of comments in each file's `comments` array does not exceed `MAX_COMMENTS_PER_STORY`.
- AC4: Logs indicate that saving data to a file was attempted for each story, reporting success or specific file writing errors.
---
### Story 2.4: Implement Stage Testing Utility for HN Fetching
- **User Story / Goal:** As a developer, I want a separate, executable script that *only* performs the HN data fetching and persistence, so I can test and trigger this stage independently of the full pipeline.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/fetch_hn_data.ts`.
- This script should perform the essential setup required for this stage: initialize logger, load configuration (`.env`), determine and create output directory (reuse or replicate logic from Epic 1 / `src/index.ts`).
- The script should then execute the core logic of fetching stories via `algoliaHNClient.fetchTopStories`, fetching comments via `algoliaHNClient.fetchCommentsForStory` (using loaded config for limit), and persisting the results to JSON files using `fs.writeFileSync` (replicating logic from Story 2.3).
- The script should log its progress using the logger utility.
- Add a new script command to `package.json` under `"scripts"`: `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/fetch_hn_data.ts` exists.
- AC2: The script `stage:fetch` is defined in `package.json`'s `scripts` section.
- AC3: Running `npm run stage:fetch` executes successfully, performing only the setup, fetch, and persist steps.
- AC4: Running `npm run stage:fetch` creates the same 10 `{storyId}_data.json` files in the correct date-stamped output directory as running the main `npm run dev` command (at the current state of development).
- AC5: Logs generated by `npm run stage:fetch` reflect only the fetching and persisting steps, not subsequent pipeline stages.

# Epic 3 File
# Epic 3: Article Scraping & Persistence
**Goal:** Implement a best-effort article scraping mechanism to fetch and extract plain text content from the external URLs associated with fetched HN stories. Handle failures gracefully and persist successfully scraped text locally. Implement a stage testing utility for scraping.
## Story List
### Story 3.1: Implement Basic Article Scraper Module
- **User Story / Goal:** As a developer, I want a module that attempts to fetch HTML from a URL and extract the main article text using basic methods, handling common failures gracefully, so article content can be prepared for summarization.
- **Detailed Requirements:**
- Create a new module: `src/scraper/articleScraper.ts`.
- Add a suitable HTML parsing/extraction library dependency (e.g., `@extractus/article-extractor` recommended for simplicity, or `cheerio` for more control). Run `npm install @extractus/article-extractor --save-prod` (or chosen alternative).
- Implement an async function `scrapeArticle(url: string): Promise<string | null>` within the module.
- Inside the function:
- Use native `Workspace` to retrieve content from the `url`. Set a reasonable timeout (e.g., 10-15 seconds). Include a `User-Agent` header to mimic a browser.
- Handle potential `Workspace` errors (network errors, timeouts) using `try...catch`.
- Check the `response.ok` status. If not okay, log error and return `null`.
- Check the `Content-Type` header of the response. If it doesn't indicate HTML (e.g., does not include `text/html`), log warning and return `null`.
- If HTML is received, attempt to extract the main article text using the chosen library (`article-extractor` preferred).
- Wrap the extraction logic in a `try...catch` to handle library-specific errors.
- Return the extracted plain text string if successful. Ensure it's just text, not HTML markup.
- Return `null` if extraction fails or results in empty content.
- Log all significant events, errors, or reasons for returning null (e.g., "Scraping URL...", "Fetch failed:", "Non-HTML content type:", "Extraction failed:", "Successfully extracted text") using the logger utility.
- Define TypeScript types/interfaces as needed.
- **Acceptance Criteria (ACs):**
- AC1: The `articleScraper.ts` module exists and exports the `scrapeArticle` function.
- AC2: The chosen scraping library (e.g., `@extractus/article-extractor`) is added to `dependencies` in `package.json`.
- AC3: `scrapeArticle` uses native `Workspace` with a timeout and User-Agent header.
- AC4: `scrapeArticle` correctly handles fetch errors, non-OK responses, and non-HTML content types by logging and returning `null`.
- AC5: `scrapeArticle` uses the chosen library to attempt text extraction from valid HTML content.
- AC6: `scrapeArticle` returns the extracted plain text on success, and `null` on any failure (fetch, non-HTML, extraction error, empty result).
- AC7: Relevant logs are produced for success, failure modes, and errors encountered during the process.
---
### Story 3.2: Integrate Article Scraping into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the article scraper into the main workflow (`src/index.ts`), attempting to scrape the article for each HN story that has a valid URL, after fetching its data.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import the `scrapeArticle` function from `src/scraper/articleScraper.ts`.
- Within the main loop iterating through the fetched stories (after comments are fetched in Epic 2):
- Check if `story.url` exists and appears to be a valid HTTP/HTTPS URL. A simple check for starting with `http://` or `https://` is sufficient.
- If the URL is missing or invalid, log a warning ("Skipping scraping for story {storyId}: Missing or invalid URL") and proceed to the next story's processing step.
- If a valid URL exists, log ("Attempting to scrape article for story {storyId} from {story.url}").
- Call `await scrapeArticle(story.url)`.
- Store the result (the extracted text string or `null`) in memory, associated with the story object (e.g., add property `articleContent: string | null`).
- Log the outcome clearly (e.g., "Successfully scraped article for story {storyId}", "Failed to scrape article for story {storyId}").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 & 2 steps, and then attempts article scraping for stories with valid URLs.
- AC2: Stories with missing or invalid URLs are skipped, and a corresponding log message is generated.
- AC3: For stories with valid URLs, the `scrapeArticle` function is called.
- AC4: Logs clearly indicate the start and success/failure outcome of the scraping attempt for each relevant story.
- AC5: Story objects held in memory after this stage contain an `articleContent` property holding the scraped text (string) or `null` if scraping was skipped or failed.
---
### Story 3.3: Persist Scraped Article Text Locally
- **User Story / Goal:** As a developer, I want to save successfully scraped article text to a separate local file for each story, so that the text content is available as input for the summarization stage.
- **Detailed Requirements:**
- Import Node.js `fs` and `path` modules if not already present in `src/index.ts`.
- In the main workflow (`src/index.ts`), immediately after a successful call to `scrapeArticle` for a story (where the result is a non-null string):
- Retrieve the full path to the current date-stamped output directory.
- Construct the filename: `{storyId}_article.txt`.
- Construct the full file path using `path.join()`.
- Get the successfully scraped article text string (`articleContent`).
- Use `fs.writeFileSync(fullPath, articleContent, 'utf-8')` to save the text to the file. Wrap in `try...catch` for file system errors.
- Log the successful saving of the file (e.g., "Saved scraped article text to {filename}") or any file writing errors encountered.
- Ensure *no* `_article.txt` file is created if `scrapeArticle` returned `null` (due to skipping or failure).
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains `_article.txt` files *only* for those stories where `scrapeArticle` succeeded and returned text content.
- AC2: The name of each article text file is `{storyId}_article.txt`.
- AC3: The content of each `_article.txt` file is the plain text string returned by `scrapeArticle`.
- AC4: Logs confirm the successful writing of each `_article.txt` file or report specific file writing errors.
- AC5: No empty `_article.txt` files are created. Files only exist if scraping was successful.
---
### Story 3.4: Implement Stage Testing Utility for Scraping
- **User Story / Goal:** As a developer, I want a separate script/command to test the article scraping logic using HN story data from local files, allowing independent testing and debugging of the scraper.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/scrape_articles.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `scrapeArticle`.
- The script should:
- Initialize the logger.
- Load configuration (to get `OUTPUT_DIR_PATH`).
- Determine the target date-stamped directory path (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`, using the current date or potentially an optional CLI argument). Ensure this directory exists.
- Read the directory contents and identify all `{storyId}_data.json` files.
- For each `_data.json` file found:
- Read and parse the JSON content.
- Extract the `storyId` and `url`.
- If a valid `url` exists, call `await scrapeArticle(url)`.
- If scraping succeeds (returns text), save the text to `{storyId}_article.txt` in the same directory (using logic from Story 3.3). Overwrite if the file exists.
- Log the progress and outcome (skip/success/fail) for each story processed.
- Add a new script command to `package.json`: `"stage:scrape": "ts-node src/stages/scrape_articles.ts"`. Consider adding argument parsing later if needed to specify a date/directory.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/scrape_articles.ts` exists.
- AC2: The script `stage:scrape` is defined in `package.json`.
- AC3: Running `npm run stage:scrape` (assuming a directory with `_data.json` files exists from a previous `stage:fetch` run) reads these files.
- AC4: The script calls `scrapeArticle` for stories with valid URLs found in the JSON files.
- AC5: The script creates/updates `{storyId}_article.txt` files in the target directory corresponding to successfully scraped articles.
- AC6: The script logs its actions (reading files, attempting scraping, saving results) for each story ID processed.
- AC7: The script operates solely based on local `_data.json` files and fetching from external article URLs; it does not call the Algolia HN API.

# Epic 4 File
# Epic 4: LLM Summarization & Persistence
**Goal:** Integrate with the configured local Ollama instance to generate summaries for successfully scraped article text and fetched comments. Persist these summaries locally. Implement a stage testing utility for summarization.
## Story List
### Story 4.1: Implement Ollama Client Module
- **User Story / Goal:** As a developer, I want a client module to interact with the configured Ollama API endpoint via HTTP, handling requests and responses for text generation, so that summaries can be generated programmatically.
- **Detailed Requirements:**
- **Prerequisite:** Ensure a local Ollama instance is installed and running, accessible via the URL defined in `.env` (`OLLAMA_ENDPOINT_URL`), and that the model specified in `.env` (`OLLAMA_MODEL`) has been downloaded (e.g., via `ollama pull model_name`). Instructions for this setup should be in the project README.
- Create a new module: `src/clients/ollamaClient.ts`.
- Implement an async function `generateSummary(promptTemplate: string, content: string): Promise<string | null>`. *(Note: Parameter name changed for clarity)*
- Add configuration variables `OLLAMA_ENDPOINT_URL` (e.g., `http://localhost:11434`) and `OLLAMA_MODEL` (e.g., `llama3`) to `.env.example`. Ensure they are loaded via the config module (`src/utils/config.ts`). Update local `.env` with actual values. Add optional `OLLAMA_TIMEOUT_MS` to `.env.example` with a default like `120000`.
- Inside `generateSummary`:
- Construct the full prompt string using the `promptTemplate` and the provided `content` (e.g., replacing a placeholder like `{Content Placeholder}` in the template, or simple concatenation if templates are basic).
- Construct the Ollama API request payload (JSON): `{ model: configured_model, prompt: full_prompt, stream: false }`. Refer to Ollama `/api/generate` documentation and `docs/data-models.md`.
- Use native `Workspace` to send a POST request to the configured Ollama endpoint + `/api/generate`. Set appropriate headers (`Content-Type: application/json`). Use the configured `OLLAMA_TIMEOUT_MS` or a reasonable default (e.g., 2 minutes).
- Handle `Workspace` errors (network, timeout) using `try...catch`.
- Check `response.ok`. If not OK, log the status/error and return `null`.
- Parse the JSON response from Ollama. Extract the generated text (typically in the `response` field). Refer to `docs/data-models.md`.
- Check for potential errors within the Ollama response structure itself (e.g., an `error` field).
- Return the extracted summary string on success. Return `null` on any failure.
- Log key events: initiating request (mention model), receiving response, success, failure reasons, potentially request/response time using the logger.
- Define necessary TypeScript types for the Ollama request payload and expected response structure in `src/types/ollama.ts` (referenced in `docs/data-models.md`).
- **Acceptance Criteria (ACs):**
- AC1: The `ollamaClient.ts` module exists and exports `generateSummary`.
- AC2: `OLLAMA_ENDPOINT_URL` and `OLLAMA_MODEL` are defined in `.env.example`, loaded via config, and used by the client. Optional `OLLAMA_TIMEOUT_MS` is handled.
- AC3: `generateSummary` sends a correctly formatted POST request (model, full prompt based on template and content, stream:false) to the configured Ollama endpoint/path using native `Workspace`.
- AC4: Network errors, timeouts, and non-OK API responses are handled gracefully, logged, and result in a `null` return (given the Prerequisite Ollama service is running).
- AC5: A successful Ollama response is parsed correctly, the generated text is extracted, and returned as a string.
* AC6: Unexpected Ollama response formats or internal errors (e.g., `{"error": "..."}`) are handled, logged, and result in a `null` return.
* AC7: Logs provide visibility into the client's interaction with the Ollama API.
---
### Story 4.2: Define Summarization Prompts
* **User Story / Goal:** As a developer, I want standardized base prompts for generating article summaries and HN discussion summaries documented centrally, ensuring consistent instructions are sent to the LLM.
* **Detailed Requirements:**
* Define two standardized base prompts (`ARTICLE_SUMMARY_PROMPT`, `DISCUSSION_SUMMARY_PROMPT`) **and document them in `docs/prompts.md`**.
* Ensure these prompts are accessible within the application code, for example, by defining them as exported constants in a dedicated module like `src/utils/prompts.ts`, which reads from or mirrors the content in `docs/prompts.md`.
* **Acceptance Criteria (ACs):**
* AC1: The `ARTICLE_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC2: The `DISCUSSION_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC3: The prompt texts documented in `docs/prompts.md` are available as constants or variables within the application code (e.g., via `src/utils/prompts.ts`) for use by the Ollama client integration.
---
### Story 4.3: Integrate Summarization into Main Workflow
* **User Story / Goal:** As a developer, I want to integrate the Ollama client into the main workflow to generate summaries for each story's scraped article text (if available) and fetched comments, using centrally defined prompts and handling potential comment length limits.
* **Detailed Requirements:**
* Modify the main execution flow in `src/index.ts` or `src/core/pipeline.ts`.
* Import `ollamaClient.generateSummary` and the prompt constants/variables (e.g., from `src/utils/prompts.ts`, which reflect `docs/prompts.md`).
* Load the optional `MAX_COMMENT_CHARS_FOR_SUMMARY` configuration value from `.env` via the config utility.
* Within the main loop iterating through stories (after article scraping/persistence in Epic 3):
* **Article Summary Generation:**
* Check if the `story` object has non-null `articleContent`.
* If yes: log "Attempting article summarization for story {storyId}", call `await generateSummary(ARTICLE_SUMMARY_PROMPT, story.articleContent)`, store the result (string or null) as `story.articleSummary`, log success/failure.
* If no: set `story.articleSummary = null`, log "Skipping article summarization: No content".
* **Discussion Summary Generation:**
* Check if the `story` object has a non-empty `comments` array.
* If yes:
* Format the `story.comments` array into a single text block suitable for the LLM prompt (e.g., concatenating `comment.text` with separators like `---`).
* **Check truncation limit:** If `MAX_COMMENT_CHARS_FOR_SUMMARY` is configured to a positive number and the `formattedCommentsText` length exceeds it, truncate `formattedCommentsText` to the limit and log a warning: "Comment text truncated to {limit} characters for summarization for story {storyId}".
* Log "Attempting discussion summarization for story {storyId}".
* Call `await generateSummary(DISCUSSION_SUMMARY_PROMPT, formattedCommentsText)`. *(Pass the potentially truncated text)*
* Store the result (string or null) as `story.discussionSummary`. Log success/failure.
* If no: set `story.discussionSummary = null`, log "Skipping discussion summarization: No comments".
* **Acceptance Criteria (ACs):**
* AC1: Running `npm run dev` executes steps from Epics 1-3, then attempts summarization using the Ollama client.
* AC2: Article summary is attempted only if `articleContent` exists for a story.
* AC3: Discussion summary is attempted only if `comments` exist for a story.
* AC4: `generateSummary` is called with the correct prompts (sourced consistently with `docs/prompts.md`) and corresponding content (article text or formatted/potentially truncated comments).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and comment text exceeds it, the text passed to `generateSummary` is truncated, and a warning is logged.
* AC6: Logs clearly indicate the start, success, or failure (including null returns from the client) for both article and discussion summarization attempts per story.
* AC7: Story objects in memory now contain `articleSummary` (string/null) and `discussionSummary` (string/null) properties.
---
### Story 4.4: Persist Generated Summaries Locally
*(No changes needed for this story based on recent decisions)*
- **User Story / Goal:** As a developer, I want to save the generated article and discussion summaries (or null placeholders) to a local JSON file for each story, making them available for the email assembly stage.
- **Detailed Requirements:**
- Define the structure for the summary output file: `{storyId}_summary.json`. Content example: `{ "storyId": "...", "articleSummary": "...", "discussionSummary": "...", "summarizedAt": "ISO_TIMESTAMP" }`. Note that `articleSummary` and `discussionSummary` can be `null`.
- Import `fs` and `path` in `src/index.ts` or `src/core/pipeline.ts` if needed.
- In the main workflow loop, after *both* summarization attempts (article and discussion) for a story are complete:
- Create a summary result object containing `storyId`, `articleSummary` (string or null), `discussionSummary` (string or null), and the current ISO timestamp (`new Date().toISOString()`). Add this timestamp to the in-memory `story` object as well (`story.summarizedAt`).
- Get the full path to the date-stamped output directory.
- Construct the filename: `{storyId}_summary.json`.
- Construct the full file path using `path.join()`.
- Serialize the summary result object to JSON (`JSON.stringify(..., null, 2)`).
- Use `fs.writeFileSync` to save the JSON to the file, wrapping in `try...catch`.
- Log the successful saving of the summary file or any file writing errors.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains 10 files named `{storyId}_summary.json`.
- AC2: Each `_summary.json` file contains valid JSON adhering to the defined structure.
- AC3: The `articleSummary` field contains the generated summary string if successful, otherwise `null`.
- AC4: The `discussionSummary` field contains the generated summary string if successful, otherwise `null`.
- AC5: A valid ISO timestamp is present in the `summarizedAt` field.
- AC6: Logs confirm successful writing of each summary file or report file system errors.
---
### Story 4.5: Implement Stage Testing Utility for Summarization
*(Changes needed to reflect prompt sourcing and optional truncation)*
* **User Story / Goal:** As a developer, I want a separate script/command to test the LLM summarization logic using locally persisted data (HN comments, scraped article text), allowing independent testing of prompts and Ollama interaction.
* **Detailed Requirements:**
* Create a new standalone script file: `src/stages/summarize_content.ts`.
* Import necessary modules: `fs`, `path`, `logger`, `config`, `ollamaClient`, prompt constants (e.g., from `src/utils/prompts.ts`).
* The script should:
* Initialize logger, load configuration (Ollama endpoint/model, output dir, **optional `MAX_COMMENT_CHARS_FOR_SUMMARY`**).
* Determine target date-stamped directory path.
* Find all `{storyId}_data.json` files in the directory.
* For each `storyId` found:
* Read `{storyId}_data.json` to get comments. Format them into a single text block.
* *Attempt* to read `{storyId}_article.txt`. Handle file-not-found gracefully. Store content or null.
* Call `ollamaClient.generateSummary` for article text (if not null) using `ARTICLE_SUMMARY_PROMPT`.
* **Apply truncation logic:** If comments exist, check `MAX_COMMENT_CHARS_FOR_SUMMARY` and truncate the formatted comment text block if needed, logging a warning.
* Call `ollamaClient.generateSummary` for formatted comments (if comments exist) using `DISCUSSION_SUMMARY_PROMPT` *(passing potentially truncated text)*.
* Construct the summary result object (with summaries or nulls, and timestamp).
* Save the result object to `{storyId}_summary.json` in the same directory (using logic from Story 4.4), overwriting if exists.
* Log progress (reading files, calling Ollama, truncation warnings, saving results) for each story ID.
* Add script to `package.json`: `"stage:summarize": "ts-node src/stages/summarize_content.ts"`.
* **Acceptance Criteria (ACs):**
* AC1: The file `src/stages/summarize_content.ts` exists.
* AC2: The script `stage:summarize` is defined in `package.json`.
* AC3: Running `npm run stage:summarize` (after `stage:fetch` and `stage:scrape` runs) reads `_data.json` and attempts to read `_article.txt` files from the target directory.
* AC4: The script calls the `ollamaClient` with correct prompts (sourced consistently with `docs/prompts.md`) and content derived *only* from the local files (requires Ollama service running per Story 4.1 prerequisite).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and applicable, comment text is truncated before calling the client, and a warning is logged.
* AC6: The script creates/updates `{storyId}_summary.json` files in the target directory reflecting the results of the Ollama calls (summaries or nulls).
* AC7: Logs show the script processing each story ID found locally, interacting with Ollama, and saving results.
* AC8: The script does not call Algolia API or the article scraper module.

# Epic 5: Digest Assembly & Email Dispatch
**Goal:** Assemble the collected story data and summaries from local files, format them into a readable HTML email digest, and send the email using Nodemailer with configured credentials. Implement a stage testing utility for emailing with a dry-run option.
## Story List
### Story 5.1: Implement Email Content Assembler
- **User Story / Goal:** As a developer, I want a module that reads the persisted story metadata (`_data.json`) and summaries (`_summary.json`) from a specified directory, consolidating the necessary information needed to render the email digest.
- **Detailed Requirements:**
- Create a new module: `src/email/contentAssembler.ts`.
- Define a TypeScript type/interface `DigestData` representing the data needed per story for the email template: `{ storyId: string, title: string, hnUrl: string, articleUrl: string | null, articleSummary: string | null, discussionSummary: string | null }`.
- Implement an async function `assembleDigestData(dateDirPath: string): Promise<DigestData[]>`.
- The function should:
- Use Node.js `fs` to read the contents of the `dateDirPath`.
- Identify all files matching the pattern `{storyId}_data.json`.
- For each `storyId` found:
- Read and parse the `{storyId}_data.json` file. Extract `title`, `hnUrl`, and `url` (use as `articleUrl`). Handle potential file read/parse errors gracefully (log and skip story).
- Attempt to read and parse the corresponding `{storyId}_summary.json` file. Handle file-not-found or parse errors gracefully (treat `articleSummary` and `discussionSummary` as `null`).
- Construct a `DigestData` object for the story, including the extracted metadata and summaries (or nulls).
- Collect all successfully constructed `DigestData` objects into an array.
- Return the array. It should ideally contain 10 items if all previous stages succeeded.
- Log progress (e.g., "Assembling digest data from directory...", "Processing story {storyId}...") and any errors encountered during file processing using the logger.
- **Acceptance Criteria (ACs):**
- AC1: The `contentAssembler.ts` module exists and exports `assembleDigestData` and the `DigestData` type.
- AC2: `assembleDigestData` correctly reads `_data.json` files from the provided directory path.
- AC3: It attempts to read corresponding `_summary.json` files, correctly handling cases where the summary file might be missing or unparseable (resulting in null summaries for that story).
- AC4: The function returns a promise resolving to an array of `DigestData` objects, populated with data extracted from the files.
- AC5: Errors during file reading or JSON parsing are logged, and the function returns data for successfully processed stories.
---
### Story 5.2: Create HTML Email Template & Renderer
- **User Story / Goal:** As a developer, I want a basic HTML email template and a function to render it with the assembled digest data, producing the final HTML content for the email body.
- **Detailed Requirements:**
- Define the HTML structure. This can be done using template literals within a function or potentially using a simple template file (e.g., `src/email/templates/digestTemplate.html`) and `fs.readFileSync`. Template literals are simpler for MVP.
- Create a function `renderDigestHtml(data: DigestData[], digestDate: string): string` (e.g., in `src/email/contentAssembler.ts` or a new `templater.ts`).
- The function should generate an HTML string with:
- A suitable title in the body (e.g., `<h1>Hacker News Top 10 Summaries for ${digestDate}</h1>`).
- A loop through the `data` array.
- For each `story` in `data`:
- Display `<h2><a href="${story.articleUrl || story.hnUrl}">${story.title}</a></h2>`.
- Display `<p><a href="${story.hnUrl}">View HN Discussion</a></p>`.
- Conditionally display `<h3>Article Summary</h3><p>${story.articleSummary}</p>` *only if* `story.articleSummary` is not null/empty.
- Conditionally display `<h3>Discussion Summary</h3><p>${story.discussionSummary}</p>` *only if* `story.discussionSummary` is not null/empty.
- Include a separator (e.g., `<hr style="margin-top: 20px; margin-bottom: 20px;">`).
- Use basic inline CSS for minimal styling (margins, etc.) to ensure readability. Avoid complex layouts.
- Return the complete HTML document as a string.
- **Acceptance Criteria (ACs):**
- AC1: A function `renderDigestHtml` exists that accepts the digest data array and a date string.
- AC2: The function returns a single, complete HTML string.
- AC3: The generated HTML includes a title with the date and correctly iterates through the story data.
- AC4: For each story, the HTML displays the linked title, HN link, and conditionally displays the article and discussion summaries with headings.
- AC5: Basic separators and margins are used for readability. The HTML is simple and likely to render reasonably in most email clients.
---
### Story 5.3: Implement Nodemailer Email Sender
- **User Story / Goal:** As a developer, I want a module to send the generated HTML email using Nodemailer, configured with credentials stored securely in the environment file.
- **Detailed Requirements:**
- Add Nodemailer dependencies: `npm install nodemailer @types/nodemailer --save-prod`.
- Add required configuration variables to `.env.example` (and local `.env`): `EMAIL_HOST`, `EMAIL_PORT` (e.g., 587), `EMAIL_SECURE` (e.g., `false` for STARTTLS on 587, `true` for 465), `EMAIL_USER`, `EMAIL_PASS`, `EMAIL_FROM` (e.g., `"Your Name <you@example.com>"`), `EMAIL_RECIPIENTS` (comma-separated list).
- Create a new module: `src/email/emailSender.ts`.
- Implement an async function `sendDigestEmail(subject: string, htmlContent: string): Promise<boolean>`.
- Inside the function:
- Load the `EMAIL_*` variables from the config module.
- Create a Nodemailer transporter using `nodemailer.createTransport` with the loaded config (host, port, secure flag, auth: { user, pass }).
- Verify transporter configuration using `transporter.verify()` (optional but recommended). Log verification success/failure.
- Parse the `EMAIL_RECIPIENTS` string into an array or comma-separated string suitable for the `to` field.
- Define the `mailOptions`: `{ from: EMAIL_FROM, to: parsedRecipients, subject: subject, html: htmlContent }`.
- Call `await transporter.sendMail(mailOptions)`.
- If `sendMail` succeeds, log the success message including the `messageId` from the result. Return `true`.
- If `sendMail` fails (throws error), log the error using the logger. Return `false`.
- **Acceptance Criteria (ACs):**
- AC1: `nodemailer` and `@types/nodemailer` dependencies are added.
- AC2: `EMAIL_*` variables are defined in `.env.example` and loaded from config.
- AC3: `emailSender.ts` module exists and exports `sendDigestEmail`.
- AC4: `sendDigestEmail` correctly creates a Nodemailer transporter using configuration from `.env`. Transporter verification is attempted (optional AC).
- AC5: The `to` field is correctly populated based on `EMAIL_RECIPIENTS`.
- AC6: `transporter.sendMail` is called with correct `from`, `to`, `subject`, and `html` options.
- AC7: Email sending success (including message ID) or failure is logged clearly.
- AC8: The function returns `true` on successful sending, `false` otherwise.
---
### Story 5.4: Integrate Email Assembly and Sending into Main Workflow
- **User Story / Goal:** As a developer, I want the main application workflow (`src/index.ts`) to orchestrate the final steps: assembling digest data, rendering the HTML, and triggering the email send after all previous stages are complete.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`.
- Execute these steps *after* the main loop (where stories are fetched, scraped, summarized, and persisted) completes:
- Log "Starting final digest assembly and email dispatch...".
- Determine the path to the current date-stamped output directory.
- Call `const digestData = await assembleDigestData(dateDirPath)`.
- Check if `digestData` array is not empty.
- If yes:
- Get the current date string (e.g., 'YYYY-MM-DD').
- `const htmlContent = renderDigestHtml(digestData, currentDate)`.
- `const subject = \`BMad Hacker Daily Digest - ${currentDate}\``.
- `const emailSent = await sendDigestEmail(subject, htmlContent)`.
- Log the final outcome based on `emailSent` ("Digest email sent successfully." or "Failed to send digest email.").
- If no (`digestData` is empty or assembly failed):
- Log an error: "Failed to assemble digest data or no data found. Skipping email."
- Log "BMad Hacker Daily Digest process finished."
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes all stages (Epics 1-4) and then proceeds to email assembly and sending.
- AC2: `assembleDigestData` is called correctly with the output directory path after other processing is done.
- AC3: If data is assembled, `renderDigestHtml` and `sendDigestEmail` are called with the correct data, subject, and HTML.
- AC4: The final success or failure of the email sending step is logged.
- AC5: If `assembleDigestData` returns no data, email sending is skipped, and an appropriate message is logged.
- AC6: The application logs a final completion message.
---
### Story 5.5: Implement Stage Testing Utility for Emailing
- **User Story / Goal:** As a developer, I want a separate script/command to test the email assembly, rendering, and sending logic using persisted local data, including a crucial `--dry-run` option to prevent accidental email sending during tests.
- **Detailed Requirements:**
- Add `yargs` dependency for argument parsing: `npm install yargs @types/yargs --save-dev`.
- Create a new standalone script file: `src/stages/send_digest.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`, `yargs`.
- Use `yargs` to parse command-line arguments, specifically looking for a `--dry-run` boolean flag (defaulting to `false`). Allow an optional argument for specifying the date-stamped directory, otherwise default to current date.
- The script should:
- Initialize logger, load config.
- Determine the target date-stamped directory path (from arg or default). Log the target directory.
- Call `await assembleDigestData(dateDirPath)`.
- If data is assembled and not empty:
- Determine the date string for the subject/title.
- Call `renderDigestHtml(digestData, dateString)` to get HTML.
- Construct the subject string.
- Check the `dryRun` flag:
- If `true`: Log "DRY RUN enabled. Skipping actual email send.". Log the subject. Save the `htmlContent` to a file in the target directory (e.g., `_digest_preview.html`). Log that the preview file was saved.
- If `false`: Log "Live run: Attempting to send email...". Call `await sendDigestEmail(subject, htmlContent)`. Log success/failure based on the return value.
- If data assembly fails or is empty, log the error.
- Add script to `package.json`: `"stage:email": "ts-node src/stages/send_digest.ts --"`. The `--` allows passing arguments like `--dry-run`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/send_digest.ts` exists. `yargs` dependency is added.
- AC2: The script `stage:email` is defined in `package.json` allowing arguments.
- AC3: Running `npm run stage:email -- --dry-run` reads local data, renders HTML, logs the intent, saves `_digest_preview.html` locally, and does *not* call `sendDigestEmail`.
- AC4: Running `npm run stage:email` (without `--dry-run`) reads local data, renders HTML, and *does* call `sendDigestEmail`, logging the outcome.
- AC5: The script correctly identifies and acts upon the `--dry-run` flag.
- AC6: Logs clearly distinguish between dry runs and live runs and report success/failure.
- AC7: The script operates using only local files and the email configuration/service; it does not invoke prior pipeline stages (Algolia, scraping, Ollama).

# Demonstration of the Full BMad Workflow Agent Gem Usage
**Welcome to the complete end-to-end walkthrough of the BMad Method V2!** This demonstration showcases the power of AI-assisted software development using a phased agent approach. You'll see how each specialized agent (BA, PM, Architect, PO/SM) contributes to the project lifecycle - from initial concept to implementation-ready plans.
Each section includes links to **full Gemini interaction transcripts**, allowing you to witness the remarkable collaborative process between human and AI. The demo folder contains all output artifacts that flow between agents, creating a cohesive development pipeline.
What makes this V2 methodology exceptional is how the agents work in **interactive phases**, pausing at key decision points for your input rather than dumping massive documents at once. This creates a truly collaborative experience where you shape the outcome while the AI handles the heavy lifting.
Follow along from concept to code-ready project plan and see how this workflow transforms software development!
## BA Brainstorming
The following link shows the full chat thread with the BA demonstrating many features of this amazing agent. I started out not even knowing what to build, and it helped me ideate with the goal of something interesting for tutorial purposes, refine it, do some deep research (in thinking mode, I did not switch models), gave some great alternative details and ideas, prompted me section by section eventually to produce the brief. It worked amazingly well. You can read the full transcript and output here:
https://gemini.google.com/share/fec063449737
## PM Brainstorming (Oops it was not the PM LOL)
I took the final output md brief with prompt for the PM at the end of the last chat and created a google doc to make it easier to share with the PM (I could have probably just pasted it into the new chat, but it's easier if I want to start over). In Google Docs it's so easy to just create a new doc, right click and select 'Paste from Markdown', then click in the title and it will automatically name and save it with the title of the document. I then started a chat with the 2-PM Gem, also in Gemini 2.5 Pro thinking mode by attaching the Google doc and telling it to reference the prompt. This is the transcript. I realized that I accidentally had pasted the BA prompt also into the PM prompt, so this actually ended up producing a pretty nicely refined brief 2.0 instead LOL

So I took that output file and put it into the actual BA again to produce a new version with prompt as seen in [this file](final-brief-with-pm-prompt.txt) ([md version](final-brief-with-pm-prompt.md)).
## PM Brainstorming Take 2
I will be going forward with the rest of the process not use Google Docs even though it's preferred and instead attach txt attachments of previous phase documents, this is required or else the link will be un-sharable.
Of note here is how I am not passive in this process and you should not be either - I looked at its proposed epics in its first PRD draft after answering the initial questions and spotting something really dumb, it had a final epic for doing file output and logging all the way at the end - when really this should be happening incrementally with each epic. The Architect or PO I hope would have caught this later and the PM might also if I let it get to the checklist phase, but if you can work with it you will have quicker results and better outcomes.
Also notice, since we came to the PM with the amazing brief + prompt embedded in it - it only had like 1 question before producing the first draft - amazing!!!
The PM did a great job of asking the right questions, and producing the [Draft PRD](prd.txt) ([md version](prd.md)), and each epic, [1](epic1.txt) ([md version](epic1.md)), [2](epic2.txt) ([md version](epic2.md)), [3](epic3.txt) ([md version](epic3.md)), [4](epic4.txt) ([md version](epic4.md)), [5](epic5.txt) ([md version](epic5.md)).
The beauty of these new V2 Agents is they pause for you to answer questions or review the document generation section by section - this is so much better than receiving a massive document dump all at once and trying to take it all in. in between each piece you can ask questions or ask for changes - so easy - so powerful!
After the drafts were done, it then ran the checklist - which is the other big game changer feature of the V2 BMAD Method. Waiting for the output final decision from the checklist run can be exciting haha!
Getting that final PRD & EPIC VALIDATION SUMMARY and seeing it all passing is a great feeling.
[Here is the full chat summary](https://g.co/gemini/share/abbdff18316b).
## Architect (Terrible Architect - already fired and replaced in take 2)
I gave the architect the drafted PRD and epics. I call them all still drafts because the architect or PO could still have some findings or updates - but hopefully not for this very simple project.
I started off the fun with the architect by saying 'the prompt to respond to is in the PRD at the end in a section called 'Initial Architect Prompt' and we are in architecture creation mode - all PRD and epics planned by the PM are attached'
NOTE - The architect just plows through and produces everything at once and runs the checklist - need to improve the gem and agent to be more workflow focused in a future update! Here is the [initial crap it produced](botched-architecture.md) - don't worry I fixed it, it's much better in take 2!
There is one thing that is a pain with both Gemini and ChatGPT - output of markdown with internal markdown or mermaid sections screws up the output formatting where it thinks the start of inner markdown is the end to its total output block - this is because the reality is everything you are seeing in response from the LLM is already markdown, just being rendered by the UI! So the fix is simple - I told it "Since you already default respond in markdown - can you not use markdown blocks and just give the document as standard chat output" - this worked perfect, and nested markdown was properly still wrapped!
I updated the agent at this point to fix this output formatting for all gems and adjusted the architect to progress document by document prompting in between to get clarifications, suggest tradeoffs or what it put in place, etc., and then confirm with me if I like all the draft docs we got 1 by 1 and then confirm I am ready for it to run the checklist assessment. Improved usage of this is shown in the next section Architect Take 2 next.
If you want to see my annoying chat with this lame architect gem that is now much better - [here you go](https://g.co/gemini/share/0a029a45d70b).
{I corrected the interaction model and added YOLO mode to the architect, and tried a fresh start with the improved gem in take 2.}
## Architect Take 2 (Our amazing new architect)
Same initial prompt as before but with the new and improved architect! I submitted that first prompt again and waited in anticipation to see if it would go insane again.
So far success - it confirmed it was not to go all YOLO on me!
Our new architect is SO much better, and also fun '(Pirate voice) Aye, yargs be a fine choice, matey!' - firing the previous architect was a great decision!
It gave us our [tech stack](tech-stack.txt) ([md version](tech-stack.md)) - the tech-stack looks great, it did not produce wishy-washy ambiguous selections like the previous architect would!
I did mention we should call out the specific decisions to not use axios and dotenv so the LLM would not try to use it later. Also I suggested adding Winston and it helped me know it had a better simpler idea for MVP for file logging! Such a great helper now! I really hope I never see that old V1 architect again, I don't think he was at all qualified to even mop the floors.
When I got the [project structure document](project-structure.txt) ([md version](project-structure.md)), I was blown away - you will see in the chat transcript how it was formatted - I was able to copy the whole response put it in an md file and no more issues with sub sections, just removed the text basically saying here is your file! Once confirmed it was md, I changed it to txt for pass off later potentially to the PO.
Here are the remaining docs it did with me one at a time before running the checklist:
- [Architecture](architecture.txt) ([md version](architecture.md)) - the 'Core Workflow / Sequence Diagram (Main Pipeline)' diagram was impressive - one other diagram had a mermaid bugs - I updated the agent and fixed the bugs, these should hopefully not occur again - it was the most common LLM mermaid bug I have gotten across models
- [Data Models](data-models.txt) ([md version](data-models.md)) - another complex file easy to just get the end of message ... copy the response and paste into markdown, perfect result!
- [API Reference](api-reference.txt) ([md version](api-reference.md))
- [Env Vars](environment-vars.txt) ([md version](environment-vars.md))
- [Coding Standards](coding-standards.txt) ([md version](coding-standards.md))
- [Testing Strategy](testing-strategy.txt) ([md version](testing-strategy.md)) - It really nailed this one, even having me ensure it captured by concerns about testing each epic with scripts incrementally - which I did confirm was awesome!
It then confirmed it was done with all the artifacts and ready to assess with its checklist! Here are the results: 5 minor points and great questions - some I answered, one I didn't understand and it explained it to me in detail!
I made the updates, and it also proposed a new file for this project specifically! [Prompts](prompts.txt) ([md version](prompts.md)) - I did have it take the output from that to ensure its referenced where needed including epic 4 and coding standards, it helped me regenerate epic 4 with the changes.
We were done, I told it great job, the output it gave me next was perfect showing the complete function of the multiphased agent! Here is a snippet!
```text
Next Steps:
The project can now move into the implementation phase, using these architecture documents as the blueprint. Development agents can be tasked with implementing the stories within each Epic, following the defined structure, standards, and testing strategy.
As the 3-Architect, I can switch to Mode 3: Master Architect Advisory if you need further assistance during development, such as:
Explaining architectural concepts.
Advising on implementation challenges.
Evaluating potential changes or enhancements.
Helping manage technical debt.
```
Here is the [full massive architecture discussion link](https://g.co/gemini/share/4fedc292e068)!
## PO-SM
This mode is WILD in Gemini 2.5 Pro with its massive 1 million context window - holy crap! It was able to analyze every artifact together - since there is a 10 document attach limit I created a [Combined Artifacts](combined-artifacts-for-posm.txt) ([md version](combined-artifacts-for-posm.md)) which adds all 5 epic files in it.
There was a ton of output running through the checklist - but the amazing part is it considered it all and output this (in better formatted markdown I didn't capture here well). TL;DR of the following - it caught two great finds! It called out that story 1.2 still calls for dotenv which we are not going to use after working with the architect, and also it is looking for a prompts.md that is called out - but I forgot to attach it, so it caught that! So I corrected story 1.2 and we are ready to proceed with development!

Recommendations
While not critical, Story 1.2 could explicitly state npm install {dotenv library} rather than just referencing the library name, for absolute clarity, although the plan specifies native Node.js .env support which negates the need for a library [111, 549]. Correction: The plan correctly states native support is used and no external package is needed [549], removing this minor concern. The reference to installing dotenv in Story 1.2 [111-112] seems contradictory to the environment-vars.txt [549] and tech-stack.txt [867] which state native support is used and dotenv is not needed. This should be clarified/corrected in Story 1.2. Update: Reviewing Story 1.2 [111], it does explicitly require installing dotenv, which contradicts ENV [549], ARCH [72], TS [867], and PRD [752] (which implies native support via .env.example). This inconsistency needs resolution. Decision: Assuming ENV, ARCH, TS, PRD are correct and Story 1.2 requirement for dotenv package is an error. Will proceed assuming NO dotenv package required.
Consider adding a docs/prompts.md file explicitly, as referenced in ARCH [89] and E4 Story 4.2 [321], even if prompts are simple initially. Update: E4 Story 4.2 [321-325] does require creating docs/prompts.md and referencing it. This seems sufficient.
Final Decision
APPROVED: The plan is comprehensive, meticulously detailed across PRD, Architecture, Epics, and supporting documents. The sequencing is logical, dependencies are managed, risks acknowledged, and the scope aligns tightly with MVP goals. The technical constraints are respected, and the use of stage testing utilities significantly enhances testability and validation. The identified inconsistency regarding the dotenv package is noted but assumed resolved in favour of native Node.js support based on multiple other document references. The plan is ready for implementation.
Transitioning to SM Mode can proceed upon user confirmation or if auto-proceeding.

## PO-SM Story Generation
This is only for demonstration as I do not like to work this way, at this point I want to be into the project - but for fun and testing, I wanted to verify the gem can produce quality stories, potentially multiple at once in case someone were wanting to use this more like taskmaster.
The output looks decent, I still prefer doing this in the IDE with Sonnet 3.5/3.7 though 1 story at a time with the SM, then use the Dev. Mainly because it's still possible you might want to change something story to story - but this is just a preference, and this method of generating all the stories at once might work well for you - experiment and let me know what you find!
- [Story Drafts Epic 1](epic-1-stories-demo.md)
- [Story Drafts Epic 2](epic-2-stories-demo.md)
- [Story Drafts Epic 3](epic-3-stories-demo.md)
etc...
Here is the full [4-POSM chat record](https://g.co/gemini/share/9ab02d1baa18).
Ill post the link to the video and final project here if you want to see the final results of the app build - but I am beyond extatic at how well this planning workflow is now tuned with V2.
Thanks if you read this far.

# BMad Hacker Daily Digest Environment Variables
## Configuration Loading Mechanism
Environment variables for this project are managed using a standard `.env` file in the project root. The application leverages the native support for `.env` files built into Node.js (v20.6.0 and later) , meaning **no external `dotenv` package is required**.
Variables defined in the `.env` file are automatically loaded into `process.env` when the Node.js application starts. Accessing and potentially validating these variables should be centralized, ideally within the `src/utils/config.ts` module .
## Required Variables
The following table lists the environment variables used by the application. An `.env.example` file should be maintained in the repository with these variables set to placeholder or default values .
| Variable Name | Description | Example / Default Value | Required? | Sensitive? | Source |
| :------------------------------ | :---------------------------------------------------------------- | :--------------------------------------- | :-------- | :--------- | :------------ |
| `OUTPUT_DIR_PATH` | Filesystem path for storing output data artifacts | `./output` | Yes | No | Epic 1 |
| `MAX_COMMENTS_PER_STORY` | Maximum number of comments to fetch per HN story | `50` | Yes | No | PRD |
| `OLLAMA_ENDPOINT_URL` | Base URL for the local Ollama API instance | `http://localhost:11434` | Yes | No | Epic 4 |
| `OLLAMA_MODEL` | Name of the Ollama model to use for summarization | `llama3` | Yes | No | Epic 4 |

## Notes
- **Secrets Management:** Sensitive variables (`EMAIL_USER`, `EMAIL_PASS`) must **never** be committed to version control. The `.env` file should be included in `.gitignore` (as per boilerplate ).
- **`.env.example`:** Maintain an `.env.example` file in the repository mirroring the variables above, using placeholders or default values for documentation and local setup .
- **Validation:** It is recommended to implement validation logic in `src/utils/config.ts` to ensure required variables are present and potentially check their format on application startup .

Okay, transitioning to **SM Mode**.
I will now generate the stories for **Epic 1: Project Initialization & Core Setup**, as requested for demonstration purposes.
I will use the details from Epic 1 in `combined-artifacts-for-posm.txt`, the `story-template.txt`, and extract relevant technical context from the supporting documents (`architecture.txt`, `project-structure.txt`, `tech-stack.txt`, `environment-vars.txt`, `testing-strategy.txt`).
**Note:** As identified during PO Mode validation, Story 1.2 contained a requirement to install the `dotenv` package [111-112], which contradicts multiple other documents stating native Node.js support is used and the package is unnecessary (`ENV` [549], `ARCH` [72], `TS` [867], `PRD` [752]). The following story for 1.2 has been generated based on the **correction** that the `dotenv` package is **not required** and native Node.js functionality should be used.
Here is the report containing the generated stories for Epic 1:

## **Stories Report: Epic 1**
**File: ai/stories/1.1.story.md**
```markdown
# Story 1.1: Initialize Project from Boilerplate
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to set up the initial project structure using the `bmad-boilerplate`, so that I have the standard tooling (TS, Jest, ESLint, Prettier), configurations, and scripts in place. [96]
**Context:** This is the foundational story for the entire project. It establishes the core development environment, tooling, and standard scripts based on the `bmad-boilerplate` template, as required by the PRD [706, 713, 784] and Architecture [43]. All subsequent development relies on the successful completion of this setup.
## Detailed Requirements
- Copy or clone the contents of the `bmad-boilerplate` into the new project's root directory. [97]
- Initialize a git repository in the project root directory (if not already done by cloning). [98]
- Ensure the `.gitignore` file from the boilerplate is present. [99]
- Run `npm install` to download and install all `devDependencies` specified in the boilerplate's `package.json`. [100]
- Verify that the core boilerplate scripts (`lint`, `format`, `test`, `build`) execute without errors on the initial codebase. [101]
## Acceptance Criteria (ACs)
- AC1: The project directory contains the files and structure from `bmad-boilerplate`. [102]
- AC2: A `node_modules` directory exists and contains packages corresponding to `devDependencies`. [103]
- AC3: `npm run lint` command completes successfully without reporting any linting errors. [104]
- AC4: `npm run format` command completes successfully, potentially making formatting changes according to Prettier rules. [105] Running it a second time should result in no changes. [106]
- AC5: `npm run test` command executes Jest successfully (it may report "no tests found" which is acceptable at this stage). [107]
- AC6: `npm run build` command executes successfully, creating a `dist` directory containing compiled JavaScript output. [108]
- AC7: The `.gitignore` file exists and includes entries for `node_modules/`, `.env`, `dist/`, etc. as specified in the boilerplate. [109, 632]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create/Copy: All files from `bmad-boilerplate` (e.g., `package.json`, `tsconfig.json`, `.eslintrc.js`, `.prettierrc.js`, `.gitignore`, initial `src/` structure if any).
- Files to Modify: None initially, verification via script execution.
- _(Hint: See `docs/project-structure.md` [813-825] for the target overall layout derived from the boilerplate)._
- **Key Technologies:**
- Node.js 22.x [851], npm [100], Git [98], TypeScript [846], Jest [889], ESLint [893], Prettier [896].
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- N/A for this story.
- **Data Structures:**
- N/A for this story.
- **Environment Variables:**
- N/A directly used, but `.gitignore` [109] should cover `.env`. Boilerplate includes `.env.example` [112].
- _(Hint: See `docs/environment-vars.md` [548-638] for all variables)._
- **Coding Standards Notes:**
- Ensure boilerplate scripts (`lint`, `format`) run successfully. [101]
- Adhere to ESLint/Prettier rules defined in the boilerplate. [746]
## Tasks / Subtasks
- [ ] Obtain the `bmad-boilerplate` content (clone or copy).
- [ ] Place boilerplate content into the project's root directory.
- [ ] Initialize git repository (`git init`).
- [ ] Verify `.gitignore` exists and is correctly sourced from boilerplate.
- [ ] Run `npm install` to install dependencies.
- [ ] Execute `npm run lint` and verify successful completion without errors.
- [ ] Execute `npm run format` and verify successful completion. Run again to confirm no further changes.
- [ ] Execute `npm run test` and verify successful execution (no tests found is OK).
- [ ] Execute `npm run build` and verify `dist/` directory creation and successful completion.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** N/A for this story (focus is project setup). [915]
- **Integration Tests:** N/A for this story. [921]
- **Manual/CLI Verification:**
- Verify file structure matches boilerplate (AC1).
- Check for `node_modules/` directory (AC2).
- Run `npm run lint` (AC3).
- Run `npm run format` twice (AC4).
- Run `npm run test` (AC5).
- Run `npm run build`, check for `dist/` (AC6).
- Inspect `.gitignore` contents (AC7).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 1.2: Setup Environment Configuration
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to establish the environment configuration mechanism using `.env` files, so that secrets and settings (like output paths) can be managed outside of version control, following boilerplate conventions and utilizing native Node.js support. [110, 549]
**Context:** This story builds on the initialized project (Story 1.1). It sets up the critical mechanism for managing configuration parameters like API keys and file paths using standard `.env` files, which is essential for security and flexibility. It leverages Node.js's built-in `.env` file loading [549, 867], meaning **no external package installation is required**. This corrects the original requirement [111-112] based on `docs/environment-vars.md` [549] and `docs/tech-stack.md` [867].
## Detailed Requirements
- Verify the `.env.example` file exists (from boilerplate). [112]
- Add an initial configuration variable `OUTPUT_DIR_PATH=./output` to `.env.example`. [113]
- Create the `.env` file locally by copying `.env.example`. Populate `OUTPUT_DIR_PATH` if needed (can keep default). [114]
- Implement a utility module (e.g., `src/utils/config.ts`) that reads environment variables **directly from `process.env`** (populated natively by Node.js from the `.env` file at startup). [115, 550]
- The utility should export the loaded configuration values (initially just `OUTPUT_DIR_PATH`). [116] It is recommended to include basic validation (e.g., checking if required variables are present). [634]
- Ensure the `.env` file is listed in `.gitignore` and is not committed. [117, 632]
## Acceptance Criteria (ACs)
- AC1: **(Removed)** The chosen `.env` library... is listed under `dependencies`. (Package not needed [549]).
- AC2: The `.env.example` file exists, is tracked by git, and contains the line `OUTPUT_DIR_PATH=./output`. [119]
- AC3: The `.env` file exists locally but is NOT tracked by git. [120]
- AC4: A configuration module (`src/utils/config.ts` or similar) exists and successfully reads the `OUTPUT_DIR_PATH` value **from `process.env`** when the application starts. [121]
- AC5: The loaded `OUTPUT_DIR_PATH` value is accessible within the application code via the config module. [122]
- AC6: The `.env` file is listed in the `.gitignore` file. [117]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/utils/config.ts`.
- Files to Modify: `.env.example`, `.gitignore` (verify inclusion of `.env`). Create local `.env`.
- _(Hint: See `docs/project-structure.md` [822] for utils location)._
- **Key Technologies:**
- Node.js 22.x (Native `.env` support >=20.6) [549, 851]. TypeScript [846].
- **No `dotenv` package required.** [549, 867]
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- N/A for this story.
- **Data Structures:**
- Potentially an interface for the exported configuration object in `config.ts`.
- _(Hint: See `docs/data-models.md` [498-547] for key project data structures)._
- **Environment Variables:**
- Reads `OUTPUT_DIR_PATH` from `process.env`. [116]
- Defines `OUTPUT_DIR_PATH` in `.env.example`. [113]
- _(Hint: See `docs/environment-vars.md` [559] for this variable)._
- **Coding Standards Notes:**
- `config.ts` should export configuration values clearly.
- Consider adding validation logic in `config.ts` to check for the presence of required environment variables on startup. [634]

- [ ] Verify `bmad-boilerplate` provided `.env.example`.
- [ ] Add `OUTPUT_DIR_PATH=./output` to `.env.example`.
- [ ] Create `.env` file by copying `.env.example`.
- [ ] Verify `.env` is included in `.gitignore`.
- [ ] Create `src/utils/config.ts`.
- [ ] Implement logic in `config.ts` to read `OUTPUT_DIR_PATH` directly from `process.env`.
- [ ] Export the loaded `OUTPUT_DIR_PATH` value from `config.ts`.
- [ ] (Optional but Recommended) Add validation in `config.ts` to ensure `OUTPUT_DIR_PATH` is defined in `process.env`.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:**
- Write unit tests for `src/utils/config.ts`. [915]
- Use `process.env` manipulation (e.g., temporarily setting `process.env.OUTPUT_DIR_PATH` within the test) to verify the module reads and exports the value correctly.
- Test validation logic (e.g., if it throws an error when a required variable is missing). [920]
- **Integration Tests:** N/A for this story. [921]
- **Manual/CLI Verification:**
- Check `.env.example` content (AC2).
- Verify `.env` exists locally but not in git status (AC3, AC6).
- Code inspection of `src/utils/config.ts` (AC4).
- Later stories (1.3, 1.4) will consume this module, verifying AC5 implicitly.
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._
## Story Wrap Up (Agent Populates After Execution)
- **Agent Model Used:** `<Agent Model Name/Version>`
- **Completion Notes:** {Implemented using native Node.js .env support, no external package installed. Added basic validation.}
- **Change Log:**
- Initial Draft (Corrected requirement to use native .env support instead of installing `dotenv` package).

# Story 1.3: Implement Basic CLI Entry Point & Execution
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a basic `src/index.ts` entry point that can be executed via the boilerplate's `dev` and `start` scripts, providing a working foundation for the application logic. [123]
**Context:** This story builds upon the project setup (Story 1.1) and environment configuration (Story 1.2). It creates the main starting point (`src/index.ts`) for the CLI application. This file will be executed by the `npm run dev` (using `ts-node`) and `npm run start` (using compiled code) scripts provided by the boilerplate. It verifies that the basic execution flow and configuration loading are functional. [730, 755]
## Detailed Requirements
- Create the main application entry point file at `src/index.ts`. [124]
- Implement minimal code within `src/index.ts` to:
- Import the configuration loading mechanism (from Story 1.2, e.g., `import config from './utils/config';`). [125]
- Log a simple startup message to the console (e.g., "BMad Hacker Daily Digest - Starting Up..."). [126]
- (Optional) Log the loaded `OUTPUT_DIR_PATH` from the imported config object to verify config loading. [127]
- Confirm execution using boilerplate scripts (`npm run dev`, `npm run build`, `npm run start`). [127]
## Acceptance Criteria (ACs)
- AC1: The `src/index.ts` file exists. [128]
- AC2: Running `npm run dev` executes `src/index.ts` via `ts-node` and logs the startup message to the console. [129]
- AC3: Running `npm run build` successfully compiles `src/index.ts` (and any imports like `config.ts`) into the `dist` directory. [130]
- AC4: Running `npm start` (after a successful build) executes the compiled code from `dist` and logs the startup message to the console. [131]
- AC5: (If implemented) The loaded `OUTPUT_DIR_PATH` is logged to the console during execution via `npm run dev` or `npm run start`. [127]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/index.ts`.
- Files to Modify: None.
- _(Hint: See `docs/project-structure.md` [822] for entry point location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Uses scripts from `package.json` (`dev`, `start`, `build`) defined in the boilerplate.
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- N/A for this story.
- **Data Structures:**
- Imports configuration object from `src/utils/config.ts` (Story 1.2).
- _(Hint: See `docs/data-models.md` [498-547] for key project data structures)._
- **Environment Variables:**
- Implicitly uses variables loaded by `config.ts` if the optional logging step [127] is implemented.
- _(Hint: See `docs/environment-vars.md` [548-638] for all variables)._
- **Coding Standards Notes:**
- Use standard `import` statements.
- Use `console.log` initially for the startup message (Logger setup is in Story 1.4).
## Tasks / Subtasks
- [ ] Create the file `src/index.ts`.
- [ ] Add import statement for the configuration module (`src/utils/config.ts`).
- [ ] Add `console.log("BMad Hacker Daily Digest - Starting Up...");` (or similar).
- [ ] (Optional) Add `console.log(\`Output directory: \${config.OUTPUT_DIR_PATH}\`);`
- [ ] Run `npm run dev` and verify console output (AC2, AC5 optional).
- [ ] Run `npm run build` and verify successful compilation to `dist/` (AC3).
- [ ] Run `npm start` and verify console output from compiled code (AC4, AC5 optional).
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** Low value for this specific story, as it's primarily wiring and execution setup. Testing `config.ts` was covered in Story 1.2. [915]
- **Integration Tests:** N/A for this story. [921]
- **Manual/CLI Verification:**
- Verify `src/index.ts` exists (AC1).
- Run `npm run dev`, check console output (AC2, AC5 opt).
- Run `npm run build`, check `dist/` exists (AC3).
- Run `npm start`, check console output (AC4, AC5 opt).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 1.4: Setup Basic Logging and Output Directory
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a basic console logging mechanism and the dynamic creation of a date-stamped output directory, so that the application can provide execution feedback and prepare for storing data artifacts in subsequent epics. [132]
**Context:** This story refines the basic execution setup from Story 1.3. It introduces a simple, reusable logger utility (`src/utils/logger.ts`) for standardized console output [871] and implements the logic to create the necessary date-stamped output directory (`./output/YYYY-MM-DD/`) based on the `OUTPUT_DIR_PATH` configured in Story 1.2. This directory is crucial for persisting intermediate data in later epics (Epics 2, 3, 4). [68, 538, 734, 788]
## Detailed Requirements
- Implement a simple, reusable logging utility module (e.g., `src/utils/logger.ts`). [133] Initially, it can wrap `console.log`, `console.warn`, `console.error`. Provide simple functions like `logInfo`, `logWarn`, `logError`. [134]
- Refactor `src/index.ts` to use this `logger` for its startup message(s) instead of `console.log`. [134]
- In `src/index.ts` (or a setup function called by it):
- Retrieve the `OUTPUT_DIR_PATH` from the configuration (imported from `src/utils/config.ts` - Story 1.2). [135]
- Determine the current date in 'YYYY-MM-DD' format (e.g., using `date-fns` library is recommended [878], needs installation `npm install date-fns --save-prod`). [136]
- Construct the full path for the date-stamped subdirectory (e.g., `${OUTPUT_DIR_PATH}/${formattedDate}`). [137]
- Check if the base output directory exists; if not, create it. [138]
- Check if the date-stamped subdirectory exists; if not, create it recursively. [139] Use Node.js `fs` module (e.g., `fs.mkdirSync(path, { recursive: true })`). Need to import `fs`. [140]
- Log (using the new logger utility) the full path of the output directory being used for the current run (e.g., "Output directory for this run: ./output/2025-05-04"). [141]
- The application should exit gracefully after performing these setup steps (for now). [147]
## Acceptance Criteria (ACs)
- AC1: A logger utility module (`src/utils/logger.ts` or similar) exists and is used for console output in `src/index.ts`. [142]
- AC2: Running `npm run dev` or `npm start` logs the startup message via the logger. [143]
- AC3: Running the application creates the base output directory (e.g., `./output` defined in `.env`) if it doesn't already exist. [144]
- AC4: Running the application creates a date-stamped subdirectory (e.g., `./output/2025-05-04`, based on current date) within the base output directory if it doesn't already exist. [145]
- AC5: The application logs a message via the logger indicating the full path to the date-stamped output directory created/used for the current execution. [146]
- AC6: The application exits gracefully after performing these setup steps (for now). [147]
- AC7: `date-fns` library is added as a production dependency.
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/utils/logger.ts`, `src/utils/dateUtils.ts` (recommended for date formatting logic).
- Files to Modify: `src/index.ts`, `package.json` (add `date-fns`), `package-lock.json`.
- _(Hint: See `docs/project-structure.md` [822] for utils location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], `fs` module (native) [140], `path` module (native, for joining paths).
- `date-fns` library [876] for date formatting (needs `npm install date-fns --save-prod`).
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- Node.js `fs.mkdirSync`. [140]
- **Data Structures:**
- N/A specific to this story, uses config from 1.2.
- _(Hint: See `docs/data-models.md` [498-547] for key project data structures)._
- **Environment Variables:**
- Uses `OUTPUT_DIR_PATH` loaded via `config.ts`. [135]
- _(Hint: See `docs/environment-vars.md` [559] for this variable)._
- **Coding Standards Notes:**
- Logger should provide simple info/warn/error functions. [134]
- Use `path.join` to construct file paths reliably.
- Handle potential errors during directory creation (e.g., permissions) using try/catch, logging errors via the new logger.
## Tasks / Subtasks
- [ ] Install `date-fns`: `npm install date-fns --save-prod`.
- [ ] Create `src/utils/logger.ts` wrapping `console` methods (e.g., `logInfo`, `logWarn`, `logError`).
- [ ] Create `src/utils/dateUtils.ts` (optional but recommended) with a function to get current date as 'YYYY-MM-DD' using `date-fns`.
- [ ] Refactor `src/index.ts` to import and use the `logger` instead of `console.log`.
- [ ] In `src/index.ts`, import `fs` and `path`.
- [ ] In `src/index.ts`, import and use the date formatting function.
- [ ] In `src/index.ts`, retrieve `OUTPUT_DIR_PATH` from config.
- [ ] In `src/index.ts`, construct the full date-stamped directory path using `path.join`.
- [ ] In `src/index.ts`, add logic using `fs.mkdirSync` (with `{ recursive: true }`) inside a try/catch block to create the directory. Log errors using the logger.
- [ ] In `src/index.ts`, log the full path of the created/used directory using the logger.
- [ ] Ensure the script completes and exits after these steps.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:**
- Test `src/utils/logger.ts` functions (can spy on `console` methods). [915]
- Test `src/utils/dateUtils.ts` function for correct date formatting.
- Testing `fs` operations in unit tests can be complex; consider focusing on integration or manual verification for directory creation. Mocking `fs` is an option but might be brittle. [918]
- **Integration Tests:**
- Could write a test that runs the core logic of `src/index.ts` (directory creation part) and uses `mock-fs` or actual file system checks (with cleanup) to verify directory creation. [921, 924]
- **Manual/CLI Verification:**
- Run `npm run dev` or `npm start`.
- Check console output uses the logger format (AC1, AC2).
- Verify the base output directory (e.g., `./output`) is created if it didn't exist (AC3).
- Verify the date-stamped subdirectory (e.g., `./output/2025-05-04`) is created (AC4). Use current date. Delete directories before re-running to confirm creation.
- Check console log for the message confirming the output directory path (AC5).
- Confirm the process exits cleanly (AC6).
- Check `package.json` for `date-fns` dependency (AC7).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.1: Implement Algolia HN API Client
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a dedicated client module to interact with the Algolia Hacker News Search API, so that fetching stories and comments is encapsulated, reusable, and uses the required native `Workspace` API. [155]
**Context:** This story creates the primary interface for retrieving data from the external Hacker News API provided by Algolia. It encapsulates the specific API calls (`GET /search` for stories and comments) and data extraction logic into a reusable module (`src/clients/algoliaHNClient.ts`). This client will be used by the main pipeline (Story 2.2) and the stage testing utility (Story 2.4). It builds upon the logger created in Epic 1 (Story 1.4). [54, 60, 62, 77]
## Detailed Requirements
- Create a new module: `src/clients/algoliaHNClient.ts`. [156]
- Implement an async function `WorkspaceTopStories` within the client: [157]
- Use native `Workspace` [749] to call the Algolia HN Search API endpoint for front-page stories (`http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10`). [4, 6, 7, 157] Adjust `hitsPerPage` if needed to ensure 10 stories.
- Parse the JSON response. [158]
- Extract required metadata for each story: `objectID` (use as `storyId`), `title`, `url` (use as `articleUrl`), `points`, `num_comments`. [159, 522] Handle potential missing `url` field gracefully (log warning using logger from Story 1.4, treat as null). [160]
- Construct the `hnUrl` for each story (e.g., `https://news.ycombinator.com/item?id={storyId}`). [161]
- Return an array of structured story objects (define a `Story` type, potentially in `src/types/hn.ts`). [162, 506-511]
- Implement a separate async function `WorkspaceCommentsForStory` within the client: [163]
- Accept `storyId` (string) and `maxComments` limit (number) as arguments. [163]
- Use native `Workspace` to call the Algolia HN Search API endpoint for comments of a specific story (`http://hn.algolia.com/api/v1/search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`). [12, 13, 14, 164]
- Parse the JSON response. [165]
- Extract required comment data: `objectID` (use as `commentId`), `comment_text`, `author`, `created_at`. [165, 524]
- Filter out comments where `comment_text` is null or empty. Ensure only up to `maxComments` are returned. [166]
- Return an array of structured comment objects (define a `Comment` type, potentially in `src/types/hn.ts`). [167, 500-505]
- Implement basic error handling using `try...catch` around `Workspace` calls and check `response.ok` status. [168] Log errors using the logger utility from Epic 1 (Story 1.4). [169]
- Define TypeScript interfaces/types for the expected structures of API responses (subset needed) and the data returned by the client functions (`Story`, `Comment`). Place these in `src/types/hn.ts`. [169, 821]
## Acceptance Criteria (ACs)
- AC1: The module `src/clients/algoliaHNClient.ts` exists and exports `WorkspaceTopStories` and `WorkspaceCommentsForStory` functions. [170]
- AC2: Calling `WorkspaceTopStories` makes a network request to the correct Algolia endpoint (`search?tags=front_page&hitsPerPage=10`) and returns a promise resolving to an array of 10 `Story` objects containing the specified metadata (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `num_comments`). [171]
- AC3: Calling `WorkspaceCommentsForStory` with a valid `storyId` and `maxComments` limit makes a network request to the correct Algolia endpoint (`search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`) and returns a promise resolving to an array of `Comment` objects (up to `maxComments`), filtering out empty ones. [172]
- AC4: Both functions use the native `Workspace` API internally. [173]
- AC5: Network errors or non-successful API responses (e.g., status 4xx, 5xx) are caught and logged using the logger from Story 1.4. [174] Functions should likely return an empty array or throw a specific error in failure cases for the caller to handle.
- AC6: Relevant TypeScript types (`Story`, `Comment`) are defined in `src/types/hn.ts` and used within the client module. [175]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/clients/algoliaHNClient.ts`, `src/types/hn.ts`.
- Files to Modify: Potentially `src/types/index.ts` if using a barrel file.
- _(Hint: See `docs/project-structure.md` [817, 821] for location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], Native `Workspace` API [863].
- Uses `logger` utility from Epic 1 (Story 1.4).
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- Algolia HN Search API `GET /search` endpoint. [2]
- Base URL: `http://hn.algolia.com/api/v1` [3]
- Parameters: `tags=front_page`, `hitsPerPage=10` (for stories) [6, 7]; `tags=comment,story_{storyId}`, `hitsPerPage={maxComments}` (for comments) [13, 14].
- Check `response.ok` and parse JSON response (`response.json()`). [168, 158, 165]
- Handle potential network errors with `try...catch`. [168]
- No authentication required. [3]
- _(Hint: See `docs/api-reference.md` [2-21] for details)._
- **Data Structures:**
- Define `Comment` interface: `{ commentId: string, commentText: string | null, author: string | null, createdAt: string }`. [501-505]
- Define `Story` interface (initial fields): `{ storyId: string, title: string, articleUrl: string | null, hnUrl: string, points?: number, numComments?: number }`. [507-511]
- (These types will be augmented in later stories [512-517]).
- Reference Algolia response subset schemas in `docs/data-models.md` [521-525].
- _(Hint: See `docs/data-models.md` for full details)._
- **Environment Variables:**
- No direct environment variables needed for this client itself (uses hardcoded base URL, fetches comment limit via argument).
- _(Hint: See `docs/environment-vars.md` [548-638] for all variables)._
- **Coding Standards Notes:**
- Use `async/await` for `Workspace` calls.
- Use logger for errors and significant events (e.g., warning if `url` is missing). [160]
- Export types and functions clearly.
## Tasks / Subtasks
- [ ] Create `src/types/hn.ts` and define `Comment` and initial `Story` interfaces.
- [ ] Create `src/clients/algoliaHNClient.ts`.
- [ ] Import necessary types and the logger utility.

- [ ] Export functions and types as needed.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Write unit tests for `src/clients/algoliaHNClient.ts`. [919]
- Mock the native `Workspace` function (e.g., using `jest.spyOn(global, 'fetch')`). [918]
- Test `WorkspaceTopStories`: Provide mock successful responses (valid JSON matching Algolia structure [521-523]) and verify correct parsing, mapping to `Story` objects [171], and `hnUrl` construction. Test with missing `url` field. Test mock error responses (network error, non-OK status) and verify error logging [174] and return value.
- Test `WorkspaceCommentsForStory`: Provide mock successful responses [524-525] and verify correct parsing, mapping to `Comment` objects, filtering of empty comments, and limiting by `maxComments` [172]. Test mock error responses and verify logging [174].

# Story 2.2: Integrate HN Data Fetching into Main Workflow
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to integrate the HN data fetching logic into the main application workflow (`src/index.ts`), so that running the app retrieves the top 10 stories and their comments after completing the setup from Epic 1. [176]
**Context:** This story connects the HN API client created in Story 2.1 to the main application entry point (`src/index.ts`) established in Epic 1 (Story 1.3). It modifies the main execution flow to call the client functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`) after the initial setup (logger, config, output directory). It uses the `MAX_COMMENTS_PER_STORY` configuration value loaded in Story 1.2. The fetched data (stories and their associated comments) is held in memory at the end of this stage. [46, 77]
## Detailed Requirements
- Modify the main execution flow in `src/index.ts` (or a main async function called by it, potentially moving logic to `src/core/pipeline.ts` as suggested by `ARCH` [46, 53] and `PS` [818]). **Recommendation:** Create `src/core/pipeline.ts` and a `runPipeline` async function, then call this function from `src/index.ts`.
- Import the `algoliaHNClient` functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`) from Story 2.1. [177]
- Import the configuration module (`src/utils/config.ts`) to access `MAX_COMMENTS_PER_STORY`. [177, 563] Also import the logger.
- In the main pipeline function, after the Epic 1 setup (config load, logger init, output dir creation):
- Call `await fetchTopStories()`. [178]
- Log the number of stories fetched (e.g., "Fetched X stories."). [179] Use the logger from Story 1.4.
- Retrieve the `MAX_COMMENTS_PER_STORY` value from the config module. Ensure it's parsed as a number. Provide a default if necessary (e.g., 50, matching `ENV` [564]).
- Iterate through the array of fetched `Story` objects. [179]
- For each `Story`:
- Log progress (e.g., "Fetching up to Y comments for story {storyId}..."). [182]
- Call `await fetchCommentsForStory()`, passing the `story.storyId` and the configured `MAX_COMMENTS_PER_STORY` value. [180]
- Store the fetched comments (the returned `Comment[]`) within the corresponding `Story` object in memory (e.g., add a `comments: Comment[]` property to the `Story` type/object). [181] Augment the `Story` type definition in `src/types/hn.ts`. [512]
- Ensure errors from the client functions are handled appropriately (e.g., log error and potentially skip comment fetching for that story).
## Acceptance Criteria (ACs)
- AC1: Running `npm run dev` executes Epic 1 setup steps followed by fetching stories and then comments for each story using the `algoliaHNClient`. [183]
- AC2: Logs (via logger) clearly show the start and successful completion of fetching stories, and the start of fetching comments for each of the 10 stories. [184]
- AC3: The configured `MAX_COMMENTS_PER_STORY` value is read from config, parsed as a number, and used in the calls to `WorkspaceCommentsForStory`. [185]
- AC4: After successful execution (before persistence in Story 2.3), `Story` objects held in memory contain a `comments` property populated with an array of fetched `Comment` objects. [186] (Verification via debugger or temporary logging).
- AC5: The `Story` type definition in `src/types/hn.ts` is updated to include the `comments: Comment[]` field. [512]
- AC6: (If implemented) Core logic is moved to `src/core/pipeline.ts` and called from `src/index.ts`. [818]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/core/pipeline.ts` (recommended).
- Files to Modify: `src/index.ts`, `src/types/hn.ts`.
- _(Hint: See `docs/project-structure.md` [818, 821, 822])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Uses `algoliaHNClient` (Story 2.1), `config` (Story 1.2), `logger` (Story 1.4).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `algoliaHNClient.fetchTopStories()` and `algoliaHNClient.fetchCommentsForStory()`.
- **Data Structures:**
- Augment `Story` interface in `src/types/hn.ts` to include `comments: Comment[]`. [512]
- Manipulates arrays of `Story` and `Comment` objects in memory.
- _(Hint: See `docs/data-models.md` [500-517])._
- **Environment Variables:**
- Reads `MAX_COMMENTS_PER_STORY` via `config.ts`. [177, 563]
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Use `async/await` for calling client functions.
- Structure fetching logic cleanly (e.g., within a loop).
- Use the logger for progress and error reporting. [182, 184]
- Consider putting the main loop logic inside the `runPipeline` function in `src/core/pipeline.ts`.
## Tasks / Subtasks
- [ ] (Recommended) Create `src/core/pipeline.ts` and define an async `runPipeline` function.
- [ ] Modify `src/index.ts` to import and call `runPipeline`. Move existing setup logic (logger init, config load, dir creation) into `runPipeline` or ensure it runs before it.
- [ ] In `pipeline.ts` (or `index.ts`), import `WorkspaceTopStories`, `WorkspaceCommentsForStory` from `algoliaHNClient`.
- [ ] Import `config` and `logger`.
- [ ] Call `WorkspaceTopStories` after initial setup. Log count.
- [ ] Retrieve `MAX_COMMENTS_PER_STORY` from `config`, ensuring it's a number.
- [ ] Update `Story` type in `src/types/hn.ts` to include `comments: Comment[]`.
- [ ] Loop through the fetched stories:
- [ ] Log comment fetching start for the story ID.
- [ ] Call `WorkspaceCommentsForStory` with `storyId` and `maxComments`.
- [ ] Handle potential errors from the client function call.
- [ ] Assign the returned comments array to the `comments` property of the current story object.
- [ ] Add temporary logging or use debugger to verify stories in memory contain comments (AC4).
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- If logic is moved to `src/core/pipeline.ts`, unit test `runPipeline`. [916]
- Mock `algoliaHNClient` functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`). [918]
- Mock `config` to provide `MAX_COMMENTS_PER_STORY`.
- Mock `logger`.
- Verify `WorkspaceTopStories` is called once.
- Verify `WorkspaceCommentsForStory` is called for each story returned by the mocked `WorkspaceTopStories`, and that it receives the correct `storyId` and `maxComments` value from config [185].
- Verify the results from mocked `WorkspaceCommentsForStory` are correctly assigned to the `comments` property of the story objects.
- **Integration Tests:**
- Could have an integration test for the fetch stage that uses the real `algoliaHNClient` (or a lightly mocked version checking calls) and verifies the in-memory data structure, but this is largely covered by the stage runner (Story 2.4). [921]
- **Manual/CLI Verification:**
- Run `npm run dev`.
- Check logs for fetching stories and comments messages [184].
- Use debugger or temporary `console.log` in the pipeline code to inspect a story object after the loop and confirm its `comments` property is populated [186].
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.3: Persist Fetched HN Data Locally
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to save the fetched HN stories (including their comments) to JSON files in the date-stamped output directory, so that the raw data is persisted locally for subsequent pipeline stages and debugging. [187]
**Context:** This story follows Story 2.2 where HN data (stories with comments) was fetched and stored in memory. Now, this data needs to be saved to the local filesystem. It uses the date-stamped output directory created in Epic 1 (Story 1.4) and writes one JSON file per story, containing the story metadata and its comments. This persisted data (`{storyId}_data.json`) is the input for subsequent stages (Scraping - Epic 3, Summarization - Epic 4, Email Assembly - Epic 5). [48, 734, 735]
## Detailed Requirements
- Define a consistent JSON structure for the output file content. [188] Example from `docs/data-models.md` [539]: `{ storyId: "...", title: "...", articleUrl: "...", hnUrl: "...", points: ..., numComments: ..., fetchedAt: "ISO_TIMESTAMP", comments: [{ commentId: "...", commentText: "...", author: "...", createdAt: "...", ... }, ...] }`. Include a timestamp (`WorkspaceedAt`) for when the data was fetched/saved. [190]
- Import Node.js `fs` (specifically `writeFileSync`) and `path` modules in the pipeline module (`src/core/pipeline.ts` or `src/index.ts`). [190] Import `date-fns` or use `new Date().toISOString()` for timestamp.
- In the main workflow (`pipeline.ts`), within the loop iterating through stories (immediately after comments have been fetched and added to the story object in Story 2.2): [191]
- Get the full path to the date-stamped output directory (this path should be determined/passed from the initial setup logic from Story 1.4). [191]
- Generate the current timestamp in ISO 8601 format (e.g., `new Date().toISOString()`) and add it to the story object as `WorkspaceedAt`. [190] Update `Story` type in `src/types/hn.ts`. [516]
- Construct the filename for the story's data: `{storyId}_data.json`. [192]
- Construct the full file path using `path.join()`. [193]
- Prepare the data object to be saved, matching the defined JSON structure (including `storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`, `WorkspaceedAt`, `comments`).
- Serialize the prepared story data object to a JSON string using `JSON.stringify(storyData, null, 2)` for readability. [194]
- Write the JSON string to the file using `fs.writeFileSync()`. Use a `try...catch` block for error handling around the file write. [195]
- Log (using the logger) the successful persistence of each story's data file or any errors encountered during file writing. [196]
## Acceptance Criteria (ACs)
- AC1: After running `npm run dev`, the date-stamped output directory (e.g., `./output/YYYY-MM-DD/`) contains exactly 10 files named `{storyId}_data.json` (assuming 10 stories were fetched successfully). [197]
- AC2: Each JSON file contains valid JSON representing a single story object, including its metadata (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`), a `WorkspaceedAt` ISO timestamp, and an array of its fetched `comments`, matching the structure defined in `docs/data-models.md` [538-540]. [198]
- AC3: The number of comments in each file's `comments` array does not exceed `MAX_COMMENTS_PER_STORY`. [199]
- AC4: Logs indicate that saving data to a file was attempted for each story, reporting success or specific file writing errors. [200]
- AC5: The `Story` type definition in `src/types/hn.ts` is updated to include the `WorkspaceedAt: string` field. [516]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Modify: `src/core/pipeline.ts` (or `src/index.ts`), `src/types/hn.ts`.
- _(Hint: See `docs/project-structure.md` [818, 821, 822])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Native `fs` module (`writeFileSync`) [190].
- Native `path` module (`join`) [193].
- `JSON.stringify` [194].
- Uses `logger` (Story 1.4).
- Uses output directory path created in Story 1.4 logic.
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- `fs.writeFileSync(filePath, jsonDataString, 'utf-8')`. [195]
- **Data Structures:**
- Uses `Story` and `Comment` types from `src/types/hn.ts`.
- Augment `Story` type to include `WorkspaceedAt: string`. [516]
- Creates JSON structure matching `{storyId}_data.json` schema in `docs/data-models.md`. [538-540]
- _(Hint: See `docs/data-models.md`)._
- **Environment Variables:**
- N/A directly, but relies on `OUTPUT_DIR_PATH` being available from config (Story 1.2) used by the directory creation logic (Story 1.4).
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Use `try...catch` for `writeFileSync` calls. [195]
- Use `JSON.stringify` with indentation (`null, 2`) for readability. [194]
- Log success/failure clearly using the logger. [196]
## Tasks / Subtasks
- [ ] In `pipeline.ts` (or `index.ts`), import `fs` and `path`.
- [ ] Update `Story` type in `src/types/hn.ts` to include `WorkspaceedAt: string`.
- [ ] Ensure the full path to the date-stamped output directory is available within the story processing loop.
- [ ] Inside the loop (after comments are fetched for a story):
- [ ] Get the current ISO timestamp (`new Date().toISOString()`).
- [ ] Add the timestamp to the story object as `WorkspaceedAt`.
- [ ] Construct the output filename: `{storyId}_data.json`.
- [ ] Construct the full file path using `path.join(outputDirPath, filename)`.
- [ ] Create the data object matching the specified JSON structure, including comments.
- [ ] Serialize the data object using `JSON.stringify(data, null, 2)`.
- [ ] Use `try...catch` block:
- [ ] Inside `try`: Call `fs.writeFileSync(fullPath, jsonString, 'utf-8')`.
- [ ] Inside `try`: Log success message with filename.
- [ ] Inside `catch`: Log file writing error with filename.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Testing file system interactions directly in unit tests can be brittle. [918]
- Focus unit tests on the data preparation logic: ensure the object created before `JSON.stringify` has the correct structure (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`, `WorkspaceedAt`, `comments`) based on a sample input `Story` object. [920]
- Verify the `WorkspaceedAt` timestamp is added correctly.
- **Integration Tests:** [921]
- Could test the file writing aspect using `mock-fs` or actual file system writes within a temporary directory (created during setup, removed during teardown). [924]
- Verify that the correct filename is generated and the content written to the mock/temporary file matches the expected JSON structure [538-540] and content.
- **Manual/CLI Verification:** [912]
- Run `npm run dev`.
- Inspect the `output/YYYY-MM-DD/` directory (use current date).
- Verify 10 files named `{storyId}_data.json` exist (AC1).
- Open a few files, visually inspect the JSON structure, check for all required fields (metadata, `WorkspaceedAt`, `comments` array), and verify comment count <= `MAX_COMMENTS_PER_STORY` (AC2, AC3).
- Check console logs for success messages for file writing or any errors (AC4).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.4: Implement Stage Testing Utility for HN Fetching
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a separate, executable script that _only_ performs the HN data fetching and persistence, so I can test and trigger this stage independently of the full pipeline. [201]
**Context:** This story addresses the PRD requirement [736] for stage-specific testing utilities [764]. It creates a standalone Node.js script (`src/stages/fetch_hn_data.ts`) that replicates the core logic of Stories 2.1, 2.2 (partially), and 2.3. This script will initialize necessary components (logger, config), call the `algoliaHNClient` to fetch stories and comments, and persist the results to the date-stamped output directory, just like the main pipeline does up to this point. This allows isolated testing of the Algolia API interaction and data persistence without running subsequent scraping, summarization, or emailing stages. [57, 62, 912]
## Detailed Requirements
- Create a new standalone script file: `src/stages/fetch_hn_data.ts`. [202]
- This script should perform the essential setup required _for this stage_:
- Initialize the logger utility (from Story 1.4). [203]
- Load configuration using the config utility (from Story 1.2) to get `MAX_COMMENTS_PER_STORY` and `OUTPUT_DIR_PATH`. [203]
- Determine the current date ('YYYY-MM-DD') using the utility from Story 1.4. [203]
- Construct the date-stamped output directory path. [203]
- Ensure the output directory exists (create it recursively if not, reusing logic/utility from Story 1.4). [203]
- The script should then execute the core logic of fetching and persistence:
- Import and use `algoliaHNClient.fetchTopStories` and `algoliaHNClient.fetchCommentsForStory` (from Story 2.1). [204]
- Import `fs` and `path`.
- Replicate the fetch loop logic from Story 2.2 (fetch stories, then loop to fetch comments for each using loaded `MAX_COMMENTS_PER_STORY` limit). [204]
- Replicate the persistence logic from Story 2.3 (add `WorkspaceedAt` timestamp, prepare data object, `JSON.stringify`, `fs.writeFileSync` to `{storyId}_data.json` in the date-stamped directory). [204]
- The script should log its progress (e.g., "Starting HN data fetch stage...", "Fetching stories...", "Fetching comments for story X...", "Saving data for story X...") using the logger utility. [205]
- Add a new script command to `package.json` under `"scripts"`: `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"`. [206]
## Acceptance Criteria (ACs)
- AC1: The file `src/stages/fetch_hn_data.ts` exists. [207]
- AC2: The script `stage:fetch` is defined in `package.json`'s `scripts` section. [208]
- AC3: Running `npm run stage:fetch` executes successfully, performing only the setup (logger, config, output dir), fetch (stories, comments), and persist steps (to JSON files). [209]
- AC4: Running `npm run stage:fetch` creates the same 10 `{storyId}_data.json` files in the correct date-stamped output directory as running the main `npm run dev` command (up to the end of Epic 2 functionality). [210]
- AC5: Logs generated by `npm run stage:fetch` reflect only the fetching and persisting steps, not subsequent pipeline stages (scraping, summarizing, emailing). [211]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/stages/fetch_hn_data.ts`.
- Files to Modify: `package.json`.
- _(Hint: See `docs/project-structure.md` [820] for stage runner location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], `ts-node` (via `npm run` script).
- Uses `logger` (Story 1.4), `config` (Story 1.2), date util (Story 1.4), directory creation logic (Story 1.4), `algoliaHNClient` (Story 2.1), `fs`/`path` (Story 2.3).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `algoliaHNClient` functions.
- Uses `fs.writeFileSync`.
- **Data Structures:**
- Uses `Story`, `Comment` types.
- Generates `{storyId}_data.json` files [538-540].
- _(Hint: See `docs/data-models.md`)._
- **Environment Variables:**
- Reads `MAX_COMMENTS_PER_STORY` and `OUTPUT_DIR_PATH` via `config.ts`.
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Structure the script clearly (setup, fetch, persist).
- Use `async/await`.
- Use logger extensively for progress indication. [205]
- Consider wrapping the main logic in an `async` IIFE (Immediately Invoked Function Expression) or a main function call.
## Tasks / Subtasks
- [ ] Create `src/stages/fetch_hn_data.ts`.
- [ ] Add imports for logger, config, date util, `algoliaHNClient`, `fs`, `path`.
- [ ] Implement setup logic: initialize logger, load config, get output dir path, ensure directory exists.
- [ ] Implement main fetch logic:
- [ ] Call `WorkspaceTopStories`.
- [ ] Get `MAX_COMMENTS_PER_STORY` from config.
- [ ] Loop through stories:
- [ ] Call `WorkspaceCommentsForStory`.
- [ ] Add comments to story object.
- [ ] Add `WorkspaceedAt` timestamp.
- [ ] Prepare data object for saving.
- [ ] Construct full file path for `{storyId}_data.json`.
- [ ] Serialize and write to file using `fs.writeFileSync` within `try...catch`.
- [ ] Log progress/success/errors.
- [ ] Add script `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"` to `package.json`.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** Unit tests for the underlying components (logger, config, client, utils) should already exist from previous stories. Unit testing the stage script itself might have limited value beyond checking basic setup calls if the core logic is just orchestrating tested components. [915]
- **Integration Tests:** N/A specifically for the script, as it _is_ an integration test itself. [921]
- **Manual/CLI Verification (Primary Test Method for this Story):** [912, 927]
- Run `npm run stage:fetch`. [209]
- Verify successful execution without errors.
- Check console logs for messages specific to fetching and persisting [211].
- Inspect the `output/YYYY-MM-DD/` directory and verify the content of the generated `{storyId}_data.json` files match expectations (similar to verification for Story 2.3) [210].
- Modify `package.json` to add the script (AC2).
- _(Hint: See `docs/testing-strategy.md` [907-950] which identifies Stage Runners as a key part of Acceptance Testing)._

# Story 2.1: Implement Algolia HN API Client
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a dedicated client module to interact with the Algolia Hacker News Search API, so that fetching stories and comments is encapsulated, reusable, and uses the required native `Workspace` API. [155]
**Context:** This story creates the primary interface for retrieving data from the external Hacker News API provided by Algolia. It encapsulates the specific API calls (`GET /search` for stories and comments) and data extraction logic into a reusable module (`src/clients/algoliaHNClient.ts`). This client will be used by the main pipeline (Story 2.2) and the stage testing utility (Story 2.4). It builds upon the logger created in Epic 1 (Story 1.4). [54, 60, 62, 77]
## Detailed Requirements
- Create a new module: `src/clients/algoliaHNClient.ts`. [156]
- Implement an async function `WorkspaceTopStories` within the client: [157]
- Use native `Workspace` [749] to call the Algolia HN Search API endpoint for front-page stories (`http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10`). [4, 6, 7, 157] Adjust `hitsPerPage` if needed to ensure 10 stories.
- Parse the JSON response. [158]
- Extract required metadata for each story: `objectID` (use as `storyId`), `title`, `url` (use as `articleUrl`), `points`, `num_comments`. [159, 522] Handle potential missing `url` field gracefully (log warning using logger from Story 1.4, treat as null). [160]
- Construct the `hnUrl` for each story (e.g., `https://news.ycombinator.com/item?id={storyId}`). [161]
- Return an array of structured story objects (define a `Story` type, potentially in `src/types/hn.ts`). [162, 506-511]
- Implement a separate async function `WorkspaceCommentsForStory` within the client: [163]
- Accept `storyId` (string) and `maxComments` limit (number) as arguments. [163]
- Use native `Workspace` to call the Algolia HN Search API endpoint for comments of a specific story (`http://hn.algolia.com/api/v1/search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`). [12, 13, 14, 164]
- Parse the JSON response. [165]
- Extract required comment data: `objectID` (use as `commentId`), `comment_text`, `author`, `created_at`. [165, 524]
- Filter out comments where `comment_text` is null or empty. Ensure only up to `maxComments` are returned. [166]
- Return an array of structured comment objects (define a `Comment` type, potentially in `src/types/hn.ts`). [167, 500-505]
- Implement basic error handling using `try...catch` around `Workspace` calls and check `response.ok` status. [168] Log errors using the logger utility from Epic 1 (Story 1.4). [169]
- Define TypeScript interfaces/types for the expected structures of API responses (subset needed) and the data returned by the client functions (`Story`, `Comment`). Place these in `src/types/hn.ts`. [169, 821]
## Acceptance Criteria (ACs)
- AC1: The module `src/clients/algoliaHNClient.ts` exists and exports `WorkspaceTopStories` and `WorkspaceCommentsForStory` functions. [170]
- AC2: Calling `WorkspaceTopStories` makes a network request to the correct Algolia endpoint (`search?tags=front_page&hitsPerPage=10`) and returns a promise resolving to an array of 10 `Story` objects containing the specified metadata (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `num_comments`). [171]
- AC3: Calling `WorkspaceCommentsForStory` with a valid `storyId` and `maxComments` limit makes a network request to the correct Algolia endpoint (`search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`) and returns a promise resolving to an array of `Comment` objects (up to `maxComments`), filtering out empty ones. [172]
- AC4: Both functions use the native `Workspace` API internally. [173]
- AC5: Network errors or non-successful API responses (e.g., status 4xx, 5xx) are caught and logged using the logger from Story 1.4. [174] Functions should likely return an empty array or throw a specific error in failure cases for the caller to handle.
- AC6: Relevant TypeScript types (`Story`, `Comment`) are defined in `src/types/hn.ts` and used within the client module. [175]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/clients/algoliaHNClient.ts`, `src/types/hn.ts`.
- Files to Modify: Potentially `src/types/index.ts` if using a barrel file.
- _(Hint: See `docs/project-structure.md` [817, 821] for location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], Native `Workspace` API [863].
- Uses `logger` utility from Epic 1 (Story 1.4).
- _(Hint: See `docs/tech-stack.md` [839-905] for full list)._
- **API Interactions / SDK Usage:**
- Algolia HN Search API `GET /search` endpoint. [2]
- Base URL: `http://hn.algolia.com/api/v1` [3]
- Parameters: `tags=front_page`, `hitsPerPage=10` (for stories) [6, 7]; `tags=comment,story_{storyId}`, `hitsPerPage={maxComments}` (for comments) [13, 14].
- Check `response.ok` and parse JSON response (`response.json()`). [168, 158, 165]
- Handle potential network errors with `try...catch`. [168]
- No authentication required. [3]
- _(Hint: See `docs/api-reference.md` [2-21] for details)._
- **Data Structures:**
- Define `Comment` interface: `{ commentId: string, commentText: string | null, author: string | null, createdAt: string }`. [501-505]
- Define `Story` interface (initial fields): `{ storyId: string, title: string, articleUrl: string | null, hnUrl: string, points?: number, numComments?: number }`. [507-511]
- (These types will be augmented in later stories [512-517]).
- Reference Algolia response subset schemas in `docs/data-models.md` [521-525].
- _(Hint: See `docs/data-models.md` for full details)._
- **Environment Variables:**
- No direct environment variables needed for this client itself (uses hardcoded base URL, fetches comment limit via argument).
- _(Hint: See `docs/environment-vars.md` [548-638] for all variables)._
- **Coding Standards Notes:**
- Use `async/await` for `Workspace` calls.
- Use logger for errors and significant events (e.g., warning if `url` is missing). [160]
- Export types and functions clearly.
## Tasks / Subtasks
- [ ] Create `src/types/hn.ts` and define `Comment` and initial `Story` interfaces.
- [ ] Create `src/clients/algoliaHNClient.ts`.

## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Write unit tests for `src/clients/algoliaHNClient.ts`. [919]
- Mock the native `Workspace` function (e.g., using `jest.spyOn(global, 'fetch')`). [918]
- Test `WorkspaceTopStories`: Provide mock successful responses (valid JSON matching Algolia structure [521-523]) and verify correct parsing, mapping to `Story` objects [171], and `hnUrl` construction. Test with missing `url` field. Test mock error responses (network error, non-OK status) and verify error logging [174] and return value.
- Test `WorkspaceCommentsForStory`: Provide mock successful responses [524-525] and verify correct parsing, mapping to `Comment` objects, filtering of empty comments, and limiting by `maxComments` [172]. Test mock error responses and verify logging [174].
- Verify `Workspace` was called with the correct URLs and parameters [171, 172].
- **Integration Tests:** N/A for this client module itself, but it will be used in pipeline integration tests later. [921]
- **Manual/CLI Verification:** Tested indirectly via Story 2.2 execution and directly via Story 2.4 stage runner. [912]
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.2: Integrate HN Data Fetching into Main Workflow
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to integrate the HN data fetching logic into the main application workflow (`src/index.ts`), so that running the app retrieves the top 10 stories and their comments after completing the setup from Epic 1. [176]
**Context:** This story connects the HN API client created in Story 2.1 to the main application entry point (`src/index.ts`) established in Epic 1 (Story 1.3). It modifies the main execution flow to call the client functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`) after the initial setup (logger, config, output directory). It uses the `MAX_COMMENTS_PER_STORY` configuration value loaded in Story 1.2. The fetched data (stories and their associated comments) is held in memory at the end of this stage. [46, 77]
## Detailed Requirements
- Modify the main execution flow in `src/index.ts` (or a main async function called by it, potentially moving logic to `src/core/pipeline.ts` as suggested by `ARCH` [46, 53] and `PS` [818]). **Recommendation:** Create `src/core/pipeline.ts` and a `runPipeline` async function, then call this function from `src/index.ts`.
- Import the `algoliaHNClient` functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`) from Story 2.1. [177]
- Import the configuration module (`src/utils/config.ts`) to access `MAX_COMMENTS_PER_STORY`. [177, 563] Also import the logger.
- In the main pipeline function, after the Epic 1 setup (config load, logger init, output dir creation):
- Call `await fetchTopStories()`. [178]
- Log the number of stories fetched (e.g., "Fetched X stories."). [179] Use the logger from Story 1.4.
- Retrieve the `MAX_COMMENTS_PER_STORY` value from the config module. Ensure it's parsed as a number. Provide a default if necessary (e.g., 50, matching `ENV` [564]).
- Iterate through the array of fetched `Story` objects. [179]
- For each `Story`:
- Log progress (e.g., "Fetching up to Y comments for story {storyId}..."). [182]
- Call `await fetchCommentsForStory()`, passing the `story.storyId` and the configured `MAX_COMMENTS_PER_STORY` value. [180]
- Store the fetched comments (the returned `Comment[]`) within the corresponding `Story` object in memory (e.g., add a `comments: Comment[]` property to the `Story` type/object). [181] Augment the `Story` type definition in `src/types/hn.ts`. [512]
- Ensure errors from the client functions are handled appropriately (e.g., log error and potentially skip comment fetching for that story).
## Acceptance Criteria (ACs)
- AC1: Running `npm run dev` executes Epic 1 setup steps followed by fetching stories and then comments for each story using the `algoliaHNClient`. [183]
- AC2: Logs (via logger) clearly show the start and successful completion of fetching stories, and the start of fetching comments for each of the 10 stories. [184]
- AC3: The configured `MAX_COMMENTS_PER_STORY` value is read from config, parsed as a number, and used in the calls to `WorkspaceCommentsForStory`. [185]
- AC4: After successful execution (before persistence in Story 2.3), `Story` objects held in memory contain a `comments` property populated with an array of fetched `Comment` objects. [186] (Verification via debugger or temporary logging).
- AC5: The `Story` type definition in `src/types/hn.ts` is updated to include the `comments: Comment[]` field. [512]
- AC6: (If implemented) Core logic is moved to `src/core/pipeline.ts` and called from `src/index.ts`. [818]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/core/pipeline.ts` (recommended).
- Files to Modify: `src/index.ts`, `src/types/hn.ts`.
- _(Hint: See `docs/project-structure.md` [818, 821, 822])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Uses `algoliaHNClient` (Story 2.1), `config` (Story 1.2), `logger` (Story 1.4).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `algoliaHNClient.fetchTopStories()` and `algoliaHNClient.fetchCommentsForStory()`.
- **Data Structures:**
- Augment `Story` interface in `src/types/hn.ts` to include `comments: Comment[]`. [512]
- Manipulates arrays of `Story` and `Comment` objects in memory.
- _(Hint: See `docs/data-models.md` [500-517])._
- **Environment Variables:**
- Reads `MAX_COMMENTS_PER_STORY` via `config.ts`. [177, 563]
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Use `async/await` for calling client functions.
- Structure fetching logic cleanly (e.g., within a loop).
- Use the logger for progress and error reporting. [182, 184]
- Consider putting the main loop logic inside the `runPipeline` function in `src/core/pipeline.ts`.
## Tasks / Subtasks
- [ ] (Recommended) Create `src/core/pipeline.ts` and define an async `runPipeline` function.
- [ ] Modify `src/index.ts` to import and call `runPipeline`. Move existing setup logic (logger init, config load, dir creation) into `runPipeline` or ensure it runs before it.
- [ ] In `pipeline.ts` (or `index.ts`), import `WorkspaceTopStories`, `WorkspaceCommentsForStory` from `algoliaHNClient`.
- [ ] Import `config` and `logger`.
- [ ] Call `WorkspaceTopStories` after initial setup. Log count.
- [ ] Retrieve `MAX_COMMENTS_PER_STORY` from `config`, ensuring it's a number.
- [ ] Update `Story` type in `src/types/hn.ts` to include `comments: Comment[]`.
- [ ] Loop through the fetched stories:
- [ ] Log comment fetching start for the story ID.
- [ ] Call `WorkspaceCommentsForStory` with `storyId` and `maxComments`.
- [ ] Handle potential errors from the client function call.
- [ ] Assign the returned comments array to the `comments` property of the current story object.
- [ ] Add temporary logging or use debugger to verify stories in memory contain comments (AC4).
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- If logic is moved to `src/core/pipeline.ts`, unit test `runPipeline`. [916]
- Mock `algoliaHNClient` functions (`WorkspaceTopStories`, `WorkspaceCommentsForStory`). [918]
- Mock `config` to provide `MAX_COMMENTS_PER_STORY`.
- Mock `logger`.
- Verify `WorkspaceTopStories` is called once.
- Verify `WorkspaceCommentsForStory` is called for each story returned by the mocked `WorkspaceTopStories`, and that it receives the correct `storyId` and `maxComments` value from config [185].
- Verify the results from mocked `WorkspaceCommentsForStory` are correctly assigned to the `comments` property of the story objects.
- **Integration Tests:**
- Could have an integration test for the fetch stage that uses the real `algoliaHNClient` (or a lightly mocked version checking calls) and verifies the in-memory data structure, but this is largely covered by the stage runner (Story 2.4). [921]
- **Manual/CLI Verification:**
- Run `npm run dev`.
- Check logs for fetching stories and comments messages [184].
- Use debugger or temporary `console.log` in the pipeline code to inspect a story object after the loop and confirm its `comments` property is populated [186].
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.3: Persist Fetched HN Data Locally
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to save the fetched HN stories (including their comments) to JSON files in the date-stamped output directory, so that the raw data is persisted locally for subsequent pipeline stages and debugging. [187]
**Context:** This story follows Story 2.2 where HN data (stories with comments) was fetched and stored in memory. Now, this data needs to be saved to the local filesystem. It uses the date-stamped output directory created in Epic 1 (Story 1.4) and writes one JSON file per story, containing the story metadata and its comments. This persisted data (`{storyId}_data.json`) is the input for subsequent stages (Scraping - Epic 3, Summarization - Epic 4, Email Assembly - Epic 5). [48, 734, 735]
## Detailed Requirements
- Define a consistent JSON structure for the output file content. [188] Example from `docs/data-models.md` [539]: `{ storyId: "...", title: "...", articleUrl: "...", hnUrl: "...", points: ..., numComments: ..., fetchedAt: "ISO_TIMESTAMP", comments: [{ commentId: "...", commentText: "...", author: "...", createdAt: "...", ... }, ...] }`. Include a timestamp (`WorkspaceedAt`) for when the data was fetched/saved. [190]
- Import Node.js `fs` (specifically `writeFileSync`) and `path` modules in the pipeline module (`src/core/pipeline.ts` or `src/index.ts`). [190] Import `date-fns` or use `new Date().toISOString()` for timestamp.
- In the main workflow (`pipeline.ts`), within the loop iterating through stories (immediately after comments have been fetched and added to the story object in Story 2.2): [191]
- Get the full path to the date-stamped output directory (this path should be determined/passed from the initial setup logic from Story 1.4). [191]
- Generate the current timestamp in ISO 8601 format (e.g., `new Date().toISOString()`) and add it to the story object as `WorkspaceedAt`. [190] Update `Story` type in `src/types/hn.ts`. [516]
- Construct the filename for the story's data: `{storyId}_data.json`. [192]
- Construct the full file path using `path.join()`. [193]
- Prepare the data object to be saved, matching the defined JSON structure (including `storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`, `WorkspaceedAt`, `comments`).
- Serialize the prepared story data object to a JSON string using `JSON.stringify(storyData, null, 2)` for readability. [194]
- Write the JSON string to the file using `fs.writeFileSync()`. Use a `try...catch` block for error handling around the file write. [195]
- Log (using the logger) the successful persistence of each story's data file or any errors encountered during file writing. [196]
## Acceptance Criteria (ACs)
- AC1: After running `npm run dev`, the date-stamped output directory (e.g., `./output/YYYY-MM-DD/`) contains exactly 10 files named `{storyId}_data.json` (assuming 10 stories were fetched successfully). [197]
- AC2: Each JSON file contains valid JSON representing a single story object, including its metadata (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`), a `WorkspaceedAt` ISO timestamp, and an array of its fetched `comments`, matching the structure defined in `docs/data-models.md` [538-540]. [198]
- AC3: The number of comments in each file's `comments` array does not exceed `MAX_COMMENTS_PER_STORY`. [199]
- AC4: Logs indicate that saving data to a file was attempted for each story, reporting success or specific file writing errors. [200]
- AC5: The `Story` type definition in `src/types/hn.ts` is updated to include the `WorkspaceedAt: string` field. [516]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Modify: `src/core/pipeline.ts` (or `src/index.ts`), `src/types/hn.ts`.
- _(Hint: See `docs/project-structure.md` [818, 821, 822])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Native `fs` module (`writeFileSync`) [190].
- Native `path` module (`join`) [193].
- `JSON.stringify` [194].
- Uses `logger` (Story 1.4).
- Uses output directory path created in Story 1.4 logic.
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- `fs.writeFileSync(filePath, jsonDataString, 'utf-8')`. [195]
- **Data Structures:**
- Uses `Story` and `Comment` types from `src/types/hn.ts`.
- Augment `Story` type to include `WorkspaceedAt: string`. [516]
- Creates JSON structure matching `{storyId}_data.json` schema in `docs/data-models.md`. [538-540]
- _(Hint: See `docs/data-models.md`)._
- **Environment Variables:**
- N/A directly, but relies on `OUTPUT_DIR_PATH` being available from config (Story 1.2) used by the directory creation logic (Story 1.4).
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Use `try...catch` for `writeFileSync` calls. [195]
- Use `JSON.stringify` with indentation (`null, 2`) for readability. [194]
- Log success/failure clearly using the logger. [196]
## Tasks / Subtasks
- [ ] In `pipeline.ts` (or `index.ts`), import `fs` and `path`.
- [ ] Update `Story` type in `src/types/hn.ts` to include `WorkspaceedAt: string`.
- [ ] Ensure the full path to the date-stamped output directory is available within the story processing loop.
- [ ] Inside the loop (after comments are fetched for a story):
- [ ] Get the current ISO timestamp (`new Date().toISOString()`).
- [ ] Add the timestamp to the story object as `WorkspaceedAt`.
- [ ] Construct the output filename: `{storyId}_data.json`.
- [ ] Construct the full file path using `path.join(outputDirPath, filename)`.
- [ ] Create the data object matching the specified JSON structure, including comments.
- [ ] Serialize the data object using `JSON.stringify(data, null, 2)`.
- [ ] Use `try...catch` block:
- [ ] Inside `try`: Call `fs.writeFileSync(fullPath, jsonString, 'utf-8')`.
- [ ] Inside `try`: Log success message with filename.
- [ ] Inside `catch`: Log file writing error with filename.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Testing file system interactions directly in unit tests can be brittle. [918]
- Focus unit tests on the data preparation logic: ensure the object created before `JSON.stringify` has the correct structure (`storyId`, `title`, `articleUrl`, `hnUrl`, `points`, `numComments`, `WorkspaceedAt`, `comments`) based on a sample input `Story` object. [920]
- Verify the `WorkspaceedAt` timestamp is added correctly.
- **Integration Tests:** [921]
- Could test the file writing aspect using `mock-fs` or actual file system writes within a temporary directory (created during setup, removed during teardown). [924]
- Verify that the correct filename is generated and the content written to the mock/temporary file matches the expected JSON structure [538-540] and content.
- **Manual/CLI Verification:** [912]
- Run `npm run dev`.
- Inspect the `output/YYYY-MM-DD/` directory (use current date).
- Verify 10 files named `{storyId}_data.json` exist (AC1).
- Open a few files, visually inspect the JSON structure, check for all required fields (metadata, `WorkspaceedAt`, `comments` array), and verify comment count <= `MAX_COMMENTS_PER_STORY` (AC2, AC3).
- Check console logs for success messages for file writing or any errors (AC4).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 2.4: Implement Stage Testing Utility for HN Fetching
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a separate, executable script that _only_ performs the HN data fetching and persistence, so I can test and trigger this stage independently of the full pipeline. [201]
**Context:** This story addresses the PRD requirement [736] for stage-specific testing utilities [764]. It creates a standalone Node.js script (`src/stages/fetch_hn_data.ts`) that replicates the core logic of Stories 2.1, 2.2 (partially), and 2.3. This script will initialize necessary components (logger, config), call the `algoliaHNClient` to fetch stories and comments, and persist the results to the date-stamped output directory, just like the main pipeline does up to this point. This allows isolated testing of the Algolia API interaction and data persistence without running subsequent scraping, summarization, or emailing stages. [57, 62, 912]
## Detailed Requirements
- Create a new standalone script file: `src/stages/fetch_hn_data.ts`. [202]
- This script should perform the essential setup required _for this stage_:
- Initialize the logger utility (from Story 1.4). [203]
- Load configuration using the config utility (from Story 1.2) to get `MAX_COMMENTS_PER_STORY` and `OUTPUT_DIR_PATH`. [203]
- Determine the current date ('YYYY-MM-DD') using the utility from Story 1.4. [203]
- Construct the date-stamped output directory path. [203]
- Ensure the output directory exists (create it recursively if not, reusing logic/utility from Story 1.4). [203]
- The script should then execute the core logic of fetching and persistence:
- Import and use `algoliaHNClient.fetchTopStories` and `algoliaHNClient.fetchCommentsForStory` (from Story 2.1). [204]
- Import `fs` and `path`.
- Replicate the fetch loop logic from Story 2.2 (fetch stories, then loop to fetch comments for each using loaded `MAX_COMMENTS_PER_STORY` limit). [204]
- Replicate the persistence logic from Story 2.3 (add `WorkspaceedAt` timestamp, prepare data object, `JSON.stringify`, `fs.writeFileSync` to `{storyId}_data.json` in the date-stamped directory). [204]
- The script should log its progress (e.g., "Starting HN data fetch stage...", "Fetching stories...", "Fetching comments for story X...", "Saving data for story X...") using the logger utility. [205]
- Add a new script command to `package.json` under `"scripts"`: `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"`. [206]
## Acceptance Criteria (ACs)
- AC1: The file `src/stages/fetch_hn_data.ts` exists. [207]
- AC2: The script `stage:fetch` is defined in `package.json`'s `scripts` section. [208]
- AC3: Running `npm run stage:fetch` executes successfully, performing only the setup (logger, config, output dir), fetch (stories, comments), and persist steps (to JSON files). [209]
- AC4: Running `npm run stage:fetch` creates the same 10 `{storyId}_data.json` files in the correct date-stamped output directory as running the main `npm run dev` command (up to the end of Epic 2 functionality). [210]
- AC5: Logs generated by `npm run stage:fetch` reflect only the fetching and persisting steps, not subsequent pipeline stages (scraping, summarizing, emailing). [211]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/stages/fetch_hn_data.ts`.
- Files to Modify: `package.json`.
- _(Hint: See `docs/project-structure.md` [820] for stage runner location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], `ts-node` (via `npm run` script).
- Uses `logger` (Story 1.4), `config` (Story 1.2), date util (Story 1.4), directory creation logic (Story 1.4), `algoliaHNClient` (Story 2.1), `fs`/`path` (Story 2.3).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `algoliaHNClient` functions.
- Uses `fs.writeFileSync`.
- **Data Structures:**
- Uses `Story`, `Comment` types.
- Generates `{storyId}_data.json` files [538-540].
- _(Hint: See `docs/data-models.md`)._
- **Environment Variables:**
- Reads `MAX_COMMENTS_PER_STORY` and `OUTPUT_DIR_PATH` via `config.ts`.
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Structure the script clearly (setup, fetch, persist).
- Use `async/await`.
- Use logger extensively for progress indication. [205]
- Consider wrapping the main logic in an `async` IIFE (Immediately Invoked Function Expression) or a main function call.
## Tasks / Subtasks
- [ ] Create `src/stages/fetch_hn_data.ts`.
- [ ] Add imports for logger, config, date util, `algoliaHNClient`, `fs`, `path`.
- [ ] Implement setup logic: initialize logger, load config, get output dir path, ensure directory exists.
- [ ] Implement main fetch logic:
- [ ] Call `WorkspaceTopStories`.
- [ ] Get `MAX_COMMENTS_PER_STORY` from config.
- [ ] Loop through stories:
- [ ] Call `WorkspaceCommentsForStory`.
- [ ] Add comments to story object.
- [ ] Add `WorkspaceedAt` timestamp.
- [ ] Prepare data object for saving.
- [ ] Construct full file path for `{storyId}_data.json`.
- [ ] Serialize and write to file using `fs.writeFileSync` within `try...catch`.
- [ ] Log progress/success/errors.
- [ ] Add script `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"` to `package.json`.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** Unit tests for the underlying components (logger, config, client, utils) should already exist from previous stories. Unit testing the stage script itself might have limited value beyond checking basic setup calls if the core logic is just orchestrating tested components. [915]
- **Integration Tests:** N/A specifically for the script, as it _is_ an integration test itself. [921]
- **Manual/CLI Verification (Primary Test Method for this Story):** [912, 927]
- Run `npm run stage:fetch`. [209]
- Verify successful execution without errors.
- Check console logs for messages specific to fetching and persisting [211].
- Inspect the `output/YYYY-MM-DD/` directory and verify the content of the generated `{storyId}_data.json` files match expectations (similar to verification for Story 2.3) [210].
- Modify `package.json` to add the script (AC2).
- _(Hint: See `docs/testing-strategy.md` [907-950] which identifies Stage Runners as a key part of Acceptance Testing)._

# Story 3.1: Implement Basic Article Scraper Module
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a module that attempts to fetch HTML from a URL and extract the main article text using basic methods, handling common failures gracefully, so article content can be prepared for summarization. [220]
**Context:** This story introduces the article scraping capability. It creates a dedicated module (`src/scraper/articleScraper.ts`) responsible for fetching content from external article URLs (found in the `{storyId}_data.json` files from Epic 2) and extracting plain text. It emphasizes using native `Workspace` and a simple extraction library (`@extractus/article-extractor` is recommended [222, 873]), and crucially, handling failures robustly (timeouts, non-HTML content, extraction errors) as required by the PRD [723, 724, 741]. This module will be used by the main pipeline (Story 3.2) and the stage tester (Story 3.4). [47, 55, 60, 63, 65]
## Detailed Requirements
- Create a new module: `src/scraper/articleScraper.ts`. [221]
- Add `@extractus/article-extractor` dependency: `npm install @extractus/article-extractor --save-prod`. [222, 223, 873]
- Implement an async function `scrapeArticle(url: string): Promise<string | null>` within the module. [223, 224]
- Inside the function:
- Use native `Workspace` [749] to retrieve content from the `url`. [224] Set a reasonable timeout (e.g., 15 seconds via `AbortSignal.timeout()`, configure via `SCRAPE_TIMEOUT_MS` [615] if needed). Include a `User-Agent` header (e.g., `"BMadHackerDigest/0.1"` or configurable via `SCRAPER_USER_AGENT` [629]). [225]
- Handle potential `Workspace` errors (network errors, timeouts) using `try...catch`. Log error using logger (from Story 1.4) and return `null`. [226]
- Check the `response.ok` status. If not okay, log error (including status code) and return `null`. [226, 227]
- Check the `Content-Type` header of the response. If it doesn't indicate HTML (e.g., does not include `text/html`), log warning and return `null`. [227, 228]
- If HTML is received (`response.text()`), attempt to extract the main article text using `@extractus/article-extractor`. [229]
- Wrap the extraction logic (`await articleExtractor.extract(htmlContent)`) in a `try...catch` to handle library-specific errors. Log error and return `null` on failure. [230]
- Return the extracted plain text (`article.content`) if successful and not empty. Ensure it's just text, not HTML markup. [231]
- Return `null` if extraction fails or results in empty content. [232]
- Log all significant events, errors, or reasons for returning null (e.g., "Scraping URL...", "Fetch failed:", "Non-OK status:", "Non-HTML content type:", "Extraction failed:", "Successfully extracted text for {url}") using the logger utility. [233]
- Define TypeScript types/interfaces as needed (though `article-extractor` types might suffice). [234]
## Acceptance Criteria (ACs)
- AC1: The `src/scraper/articleScraper.ts` module exists and exports the `scrapeArticle` function. [234]
- AC2: The `@extractus/article-extractor` library is added to `dependencies` in `package.json` and `package-lock.json` is updated. [235]
- AC3: `scrapeArticle` uses native `Workspace` with a timeout (default or configured) and a User-Agent header. [236]
- AC4: `scrapeArticle` correctly handles fetch errors (network, timeout), non-OK responses, and non-HTML content types by logging the specific reason and returning `null`. [237]
- AC5: `scrapeArticle` uses `@extractus/article-extractor` to attempt text extraction from valid HTML content fetched via `response.text()`. [238]
- AC6: `scrapeArticle` returns the extracted plain text string on success, and `null` on any failure (fetch, non-HTML, extraction error, empty result). [239]
- AC7: Relevant logs are produced using the logger for success, different failure modes, and errors encountered during the process. [240]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/scraper/articleScraper.ts`.
- Files to Modify: `package.json`, `package-lock.json`. Add optional env vars to `.env.example`.
- _(Hint: See `docs/project-structure.md` [819] for scraper location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], Native `Workspace` API [863].
- `@extractus/article-extractor` library. [873]
- Uses `logger` utility (Story 1.4).
- Uses `config` utility (Story 1.2) if implementing configurable timeout/user-agent.

- Mock native `Workspace`. Test different scenarios:
- Successful fetch (200 OK, HTML content type) -> Mock `articleExtractor` success -> Verify returned text [239].
- Successful fetch -> Mock `articleExtractor` failure/empty content -> Verify `null` return and logs [239, 240].
- Fetch returns non-OK status (e.g., 404, 500) -> Verify `null` return and logs [237, 240].
- Fetch returns non-HTML content type -> Verify `null` return and logs [237, 240].
- Fetch throws network error/timeout -> Verify `null` return and logs [237, 240].

# Story 3.2: Integrate Article Scraping into Main Workflow
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to integrate the article scraper into the main workflow (`src/core/pipeline.ts`), attempting to scrape the article for each HN story that has a valid URL, after fetching its data. [241]
**Context:** This story connects the scraper module (`articleScraper.ts` from Story 3.1) into the main application pipeline (`src/core/pipeline.ts`) developed in Epic 2. It modifies the main loop over the fetched stories (which contain data loaded in Story 2.2) to include a call to `scrapeArticle` for stories that have an article URL. The result (scraped text or null) is then stored in memory, associated with the story object. [47, 78, 79]
## Detailed Requirements
- Modify the main execution flow in `src/core/pipeline.ts` (assuming logic moved here in Story 2.2). [242]
- Import the `scrapeArticle` function from `src/scraper/articleScraper.ts`. [243] Import the logger.
- Within the main loop iterating through the fetched `Story` objects (after comments are fetched in Story 2.2 and before persistence in Story 2.3):
- Check if `story.articleUrl` exists and appears to be a valid HTTP/HTTPS URL. A simple check for starting with `http://` or `https://` is sufficient. [243, 244]
- If the URL is missing or invalid, log a warning using the logger ("Skipping scraping for story {storyId}: Missing or invalid URL") and proceed to the next step for this story (e.g., summarization in Epic 4, or persistence in Story 3.3). Set an internal placeholder for scraped content to `null`. [245]
- If a valid URL exists:
- Log ("Attempting to scrape article for story {storyId} from {story.articleUrl}"). [246]
- Call `await scrapeArticle(story.articleUrl)`. [247]
- Store the result (the extracted text string or `null`) in memory, associated with the story object. Define/add property `articleContent: string | null` to the `Story` type in `src/types/hn.ts`. [247, 513]
- Log the outcome clearly using the logger (e.g., "Successfully scraped article for story {storyId}", "Failed to scrape article for story {storyId}"). [248]
## Acceptance Criteria (ACs)
- AC1: Running `npm run dev` executes Epic 1 & 2 steps, and then attempts article scraping for stories with valid `articleUrl`s within the main pipeline loop. [249]
- AC2: Stories with missing or invalid `articleUrl`s are skipped by the scraping step, and a corresponding warning message is logged via the logger. [250]
- AC3: For stories with valid URLs, the `scrapeArticle` function from `src/scraper/articleScraper.ts` is called with the correct URL. [251]
- AC4: Logs (via logger) clearly indicate the start ("Attempting to scrape...") and the success/failure outcome of the scraping attempt for each relevant story. [252]
- AC5: Story objects held in memory after this stage contain an `articleContent` property holding the scraped text (string) or `null` if scraping was skipped or failed. [253] (Verify via debugger/logging).
- AC6: The `Story` type definition in `src/types/hn.ts` is updated to include the `articleContent: string | null` field. [513]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Modify: `src/core/pipeline.ts`, `src/types/hn.ts`.
- _(Hint: See `docs/project-structure.md` [818, 821])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Uses `articleScraper.scrapeArticle` (Story 3.1), `logger` (Story 1.4).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `scrapeArticle(url)`.
- **Data Structures:**
- Operates on `Story[]` fetched in Epic 2.
- Augment `Story` interface in `src/types/hn.ts` to include `articleContent: string | null`. [513]
- Checks `story.articleUrl`.
- _(Hint: See `docs/data-models.md` [506-517])._
- **Environment Variables:**
- N/A directly, but `scrapeArticle` might use them (Story 3.1).
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Perform the URL check before calling the scraper. [244]
- Clearly log skipping, attempt, success, failure for scraping. [245, 246, 248]
- Ensure the `articleContent` property is always set (either to the result string or explicitly to `null`).
## Tasks / Subtasks
- [ ] Update `Story` type in `src/types/hn.ts` to include `articleContent: string | null`.
- [ ] Modify the main loop in `src/core/pipeline.ts` where stories are processed.
- [ ] Import `scrapeArticle` from `src/scraper/articleScraper.ts`.
- [ ] Import `logger`.
- [ ] Inside the loop (after comment fetching, before persistence steps):
- [ ] Check if `story.articleUrl` exists and starts with `http`.
- [ ] If invalid/missing:
- [ ] Log warning message.
- [ ] Set `story.articleContent = null`.
- [ ] If valid:
- [ ] Log attempt message.
- [ ] Call `const scrapedContent = await scrapeArticle(story.articleUrl)`.
- [ ] Set `story.articleContent = scrapedContent`.
- [ ] Log success (if `scrapedContent` is not null) or failure (if `scrapedContent` is null).
- [ ] Add temporary logging or use debugger to verify `articleContent` property in story objects (AC5).
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Unit test the modified pipeline logic in `src/core/pipeline.ts`. [916]
- Mock the `scrapeArticle` function. [918]
- Provide mock `Story` objects with and without valid `articleUrl`s.
- Verify that `scrapeArticle` is called only for stories with valid URLs [251].
- Verify that the correct URL is passed to `scrapeArticle`.
- Verify that the return value (mocked text or mocked null) from `scrapeArticle` is correctly assigned to the `story.articleContent` property [253].
- Verify that appropriate logs (skip warning, attempt, success/fail) are called based on the URL validity and mocked `scrapeArticle` result [250, 252].
- **Integration Tests:** Less emphasis here; Story 3.4 provides better integration testing for scraping. [921]
- **Manual/CLI Verification:** [912]
- Run `npm run dev`.
- Check console logs for "Attempting to scrape...", "Successfully scraped...", "Failed to scrape...", and "Skipping scraping..." messages [250, 252].
- Use debugger or temporary logging to inspect `story.articleContent` values during or after the pipeline run [253].
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 3.3: Persist Scraped Article Text Locally
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want to save successfully scraped article text to a separate local file for each story, so that the text content is available as input for the summarization stage. [254]
**Context:** This story adds the persistence step for the article content scraped in Story 3.2. Following a successful scrape (where `story.articleContent` is not null), this logic writes the plain text content to a `.txt` file (`{storyId}_article.txt`) within the date-stamped output directory created in Epic 1. This ensures the scraped text is available for the next stage (Summarization - Epic 4) even if the main script is run in stages or needs to be restarted. No file should be created if scraping failed or was skipped. [49, 734, 735]
## Detailed Requirements
- Import Node.js `fs` (`writeFileSync`) and `path` modules if not already present in `src/core/pipeline.ts`. [255] Import logger.
- In the main workflow (`src/core/pipeline.ts`), within the loop processing each story, _after_ the scraping attempt (Story 3.2) is complete: [256]
- Check if `story.articleContent` is a non-null, non-empty string.
- If yes (scraping was successful and yielded content):
- Retrieve the full path to the current date-stamped output directory (available from setup). [256]
- Construct the filename: `{storyId}_article.txt`. [257]
- Construct the full file path using `path.join()`. [257]
- Get the successfully scraped article text string (`story.articleContent`). [258]
- Use `fs.writeFileSync(fullPath, story.articleContent, 'utf-8')` to save the text to the file. [259] Wrap this call in a `try...catch` block for file system errors. [260]
- Log the successful saving of the file (e.g., "Saved scraped article text to {filename}") or any file writing errors encountered, using the logger. [260]
- If `story.articleContent` is null or empty (scraping skipped or failed), ensure _no_ `_article.txt` file is created for this story. [261]
## Acceptance Criteria (ACs)
- AC1: After running `npm run dev`, the date-stamped output directory contains `_article.txt` files _only_ for those stories where `scrapeArticle` (from Story 3.1) succeeded and returned non-empty text content during the pipeline run (Story 3.2). [262]
- AC2: The name of each article text file is `{storyId}_article.txt`. [263]
- AC3: The content of each existing `_article.txt` file is the plain text string stored in `story.articleContent`. [264]
- AC4: Logs confirm the successful writing of each `_article.txt` file or report specific file writing errors. [265]
- AC5: No empty `_article.txt` files are created. Files only exist if scraping was successful and returned content. [266]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Modify: `src/core/pipeline.ts`.
- _(Hint: See `docs/project-structure.md` [818])._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851].
- Native `fs` module (`writeFileSync`). [259]
- Native `path` module (`join`). [257]
- Uses `logger` (Story 1.4).
- Uses output directory path (from Story 1.4 logic).
- Uses `story.articleContent` populated in Story 3.2.
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- `fs.writeFileSync(fullPath, articleContentString, 'utf-8')`. [259]
- **Data Structures:**
- Checks `story.articleContent` (string | null).
- Defines output file format `{storyId}_article.txt` [541].
- _(Hint: See `docs/data-models.md` [506-517, 541])._
- **Environment Variables:**
- Relies on `OUTPUT_DIR_PATH` being available (from Story 1.2/1.4).
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Place the file writing logic immediately after the scraping result is known for a story.
- Use a clear `if (story.articleContent)` check. [256]
- Use `try...catch` around `fs.writeFileSync`. [260]
- Log success/failure clearly. [260]
## Tasks / Subtasks
- [ ] In `src/core/pipeline.ts`, ensure `fs` and `path` are imported. Ensure logger is imported.
- [ ] Ensure the output directory path is available within the story processing loop.
- [ ] Inside the loop, after `story.articleContent` is set (from Story 3.2):
- [ ] Add an `if (story.articleContent)` condition.
- [ ] Inside the `if` block:
- [ ] Construct filename: `{storyId}_article.txt`.
- [ ] Construct full path using `path.join`.
- [ ] Implement `try...catch`:
- [ ] `try`: Call `fs.writeFileSync(fullPath, story.articleContent, 'utf-8')`.
- [ ] `try`: Log success message.
- [ ] `catch`: Log error message.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** [915]
- Difficult to unit test filesystem writes effectively. Focus on testing the _conditional logic_ within the pipeline function. [918]
- Mock `fs.writeFileSync`. Provide mock `Story` objects where `articleContent` is sometimes a string and sometimes null.
- Verify `fs.writeFileSync` is called _only when_ `articleContent` is a non-empty string. [262]
- Verify it's called with the correct path (`path.join(outputDir, storyId + '_article.txt')`) and content (`story.articleContent`). [263, 264]
- **Integration Tests:** [921]
- Use `mock-fs` or temporary directory setup/teardown. [924]
- Run the pipeline segment responsible for scraping (mocked) and saving.
- Verify that `.txt` files are created only for stories where the mocked scraper returned text.
- Verify file contents match the mocked text.
- **Manual/CLI Verification:** [912]
- Run `npm run dev`.
- Inspect the `output/YYYY-MM-DD/` directory.
- Check which `{storyId}_article.txt` files exist. Compare this against the console logs indicating successful/failed scraping attempts for corresponding story IDs. Verify files only exist for successful scrapes (AC1, AC5).
- Check filenames are correct (AC2).
- Open a few existing `.txt` files and spot-check the content (AC3).
- Check logs for file saving success/error messages (AC4).
- _(Hint: See `docs/testing-strategy.md` [907-950] for the overall approach)._

# Story 3.4: Implement Stage Testing Utility for Scraping
**Status:** Draft
## Goal & Context
**User Story:** As a developer, I want a separate script/command to test the article scraping logic using HN story data from local files, allowing independent testing and debugging of the scraper. [267]
**Context:** This story implements the standalone stage testing utility for Epic 3, as required by the PRD [736, 764]. It creates `src/stages/scrape_articles.ts`, which reads story data (specifically URLs) from the `{storyId}_data.json` files generated in Epic 2 (or by `stage:fetch`), calls the `scrapeArticle` function (from Story 3.1) for each URL, and persists any successfully scraped text to `{storyId}_article.txt` files (replicating Story 3.3 logic). This allows testing the scraping functionality against real websites using previously fetched story lists, without running the full pipeline or the HN fetching stage. [57, 63, 820, 912, 930]
## Detailed Requirements
- Create a new standalone script file: `src/stages/scrape_articles.ts`. [268]
- Import necessary modules: `fs` (e.g., `readdirSync`, `readFileSync`, `writeFileSync`, `existsSync`, `statSync`), `path`, `logger` (Story 1.4), `config` (Story 1.2), `scrapeArticle` (Story 3.1), date util (Story 1.4). [269]
- The script should:
- Initialize the logger. [270]
- Load configuration (to get `OUTPUT_DIR_PATH`). [271]
- Determine the target date-stamped directory path (e.g., using current date via date util, or potentially allow override via CLI arg later - current date default is fine for now). [271] Ensure this base output directory exists. Log the target directory.
- Check if the target date-stamped directory exists. If not, log an error and exit ("Directory {path} not found. Run fetch stage first?").
- Read the directory contents and identify all files ending with `_data.json`. [272] Use `fs.readdirSync` and filter.
- For each `_data.json` file found:
- Construct the full path and read its content using `fs.readFileSync`. [273]
- Parse the JSON content. Handle potential parse errors gracefully (log error, skip file). [273]
- Extract the `storyId` and `articleUrl` from the parsed data. [274]
- If a valid `articleUrl` exists (starts with `http`): [274]
- Log the attempt: "Attempting scrape for story {storyId} from {url}...".
- Call `await scrapeArticle(articleUrl)`. [274]
- If scraping succeeds (returns a non-null string):
- Construct the output filename `{storyId}_article.txt`. [275]
- Construct the full output path. [275]
- Save the text to the file using `fs.writeFileSync` (replicating logic from Story 3.3, including try/catch and logging). [275] Overwrite if the file exists. [276]
- Log success outcome.
- If scraping fails (`scrapeArticle` returns null):
- Log failure outcome.
- If `articleUrl` is missing or invalid:
- Log skipping message.
- Log overall completion: "Scraping stage finished processing {N} data files.".
- Add a new script command to `package.json`: `"stage:scrape": "ts-node src/stages/scrape_articles.ts"`. [277]
## Acceptance Criteria (ACs)
- AC1: The file `src/stages/scrape_articles.ts` exists. [279]
- AC2: The script `stage:scrape` is defined in `package.json`'s `scripts` section. [280]
- AC3: Running `npm run stage:scrape` (assuming a date-stamped directory with `_data.json` files exists from a previous fetch run) successfully reads these JSON files. [281]
- AC4: The script calls `scrapeArticle` for stories with valid `articleUrl`s found in the JSON files. [282]
- AC5: The script creates or updates `{storyId}_article.txt` files in the _same_ date-stamped directory, corresponding only to successfully scraped articles. [283]
- AC6: The script logs its actions (reading files, attempting scraping, skipping, saving results/failures) for each story ID processed based on the found `_data.json` files. [284]
- AC7: The script operates solely based on local `_data.json` files as input and fetching from external article URLs via `scrapeArticle`; it does not call the Algolia HN API client. [285, 286]
## Technical Implementation Context
**Guidance:** Use the following details for implementation. Refer to the linked `docs/` files for broader context if needed.
- **Relevant Files:**
- Files to Create: `src/stages/scrape_articles.ts`.
- Files to Modify: `package.json`.
- _(Hint: See `docs/project-structure.md` [820] for stage runner location)._
- **Key Technologies:**
- TypeScript [846], Node.js 22.x [851], `ts-node`.
- Native `fs` module (`readdirSync`, `readFileSync`, `writeFileSync`, `existsSync`, `statSync`). [269]
- Native `path` module. [269]
- Uses `logger` (Story 1.4), `config` (Story 1.2), date util (Story 1.4), `scrapeArticle` (Story 3.1), persistence logic (Story 3.3).
- _(Hint: See `docs/tech-stack.md` [839-905])._
- **API Interactions / SDK Usage:**
- Calls internal `scrapeArticle(url)`.
- Uses `fs` module extensively for reading directory, reading JSON, writing TXT.
- **Data Structures:**
- Reads JSON structure from `_data.json` files [538-540]. Extracts `storyId`, `articleUrl`.
- Creates `{storyId}_article.txt` files [541].
- _(Hint: See `docs/data-models.md`)._
- **Environment Variables:**
- Reads `OUTPUT_DIR_PATH` via `config.ts`. `scrapeArticle` might use others.
- _(Hint: See `docs/environment-vars.md` [548-638])._
- **Coding Standards Notes:**
- Structure script clearly (setup, read data files, loop, process/scrape/save).
- Use `async/await` for `scrapeArticle`.
- Implement robust error handling for file IO (reading dir, reading files, parsing JSON, writing files) using `try...catch` and logging.
- Use logger for detailed progress reporting. [284]
- Wrap main logic in an async IIFE or main function.
## Tasks / Subtasks
- [ ] Create `src/stages/scrape_articles.ts`.
- [ ] Add imports: `fs`, `path`, `logger`, `config`, `scrapeArticle`, date util.
- [ ] Implement setup: Init logger, load config, get output path, get target date-stamped path.
- [ ] Check if target date-stamped directory exists, log error and exit if not.
- [ ] Use `fs.readdirSync` to get list of files in the target directory.
- [ ] Filter the list to get only files ending in `_data.json`.
- [ ] Loop through the `_data.json` filenames:
- [ ] Construct full path for the JSON file.
- [ ] Use `try...catch` for reading and parsing the JSON file:
- [ ] `try`: Read file (`fs.readFileSync`). Parse JSON (`JSON.parse`).
- [ ] `catch`: Log error (read/parse), continue to next file.
- [ ] Extract `storyId` and `articleUrl`.
- [ ] Check if `articleUrl` is valid (starts with `http`).
- [ ] If valid:
- [ ] Log attempt.
- [ ] Call `content = await scrapeArticle(articleUrl)`.
- [ ] `if (content)`:
- [ ] Construct `.txt` output path.
- [ ] Use `try...catch` to write file (`fs.writeFileSync`). Log success/error.
- [ ] `else`: Log scrape failure.
- [ ] If URL invalid: Log skip.
- [ ] Log completion message.
- [ ] Add `"stage:scrape": "ts-node src/stages/scrape_articles.ts"` to `package.json`.
## Testing Requirements
**Guidance:** Verify implementation against the ACs using the following tests.
- **Unit Tests:** Difficult to unit test the entire script effectively due to heavy FS and orchestration logic. Focus on unit testing the core `scrapeArticle` module (Story 3.1) and utilities. [915]
- **Integration Tests:** N/A for the script itself. [921]
- **Manual/CLI Verification (Primary Test Method):** [912, 927, 930]
- Ensure `_data.json` files exist from `npm run stage:fetch` or `npm run dev`.
- Run `npm run stage:scrape`. [281]
- Verify successful execution.
- Check logs for reading files, skipping, attempting scrapes, success/failure messages, and saving messages [284].
- Inspect the `output/YYYY-MM-DD/` directory for newly created/updated `{storyId}_article.txt` files. Verify they correspond to stories where scraping succeeded according to logs [283, 285].
- Verify the script _only_ performed scraping actions based on local files (AC7).
- Modify `package.json` to add the script (AC2).
- _(Hint: See `docs/testing-strategy.md` [907-950] which identifies Stage Runners as a key part of Acceptance Testing)._

# Epic 1: Project Initialization & Core Setup
**Goal:** Initialize the project using the "bmad-boilerplate", manage dependencies, setup `.env` and config loading, establish basic CLI entry point, setup basic logging and output directory structure. This provides the foundational setup for all subsequent development work.
## Story List
### Story 1.1: Initialize Project from Boilerplate
- **User Story / Goal:** As a developer, I want to set up the initial project structure using the `bmad-boilerplate`, so that I have the standard tooling (TS, Jest, ESLint, Prettier), configurations, and scripts in place.
- **Detailed Requirements:**
- Copy or clone the contents of the `bmad-boilerplate` into the new project's root directory.
- Initialize a git repository in the project root directory (if not already done by cloning).
- Ensure the `.gitignore` file from the boilerplate is present.
- Run `npm install` to download and install all `devDependencies` specified in the boilerplate's `package.json`.
- Verify that the core boilerplate scripts (`lint`, `format`, `test`, `build`) execute without errors on the initial codebase.
- **Acceptance Criteria (ACs):**
- AC1: The project directory contains the files and structure from `bmad-boilerplate`.
- AC2: A `node_modules` directory exists and contains packages corresponding to `devDependencies`.
- AC3: `npm run lint` command completes successfully without reporting any linting errors.
- AC4: `npm run format` command completes successfully, potentially making formatting changes according to Prettier rules. Running it a second time should result in no changes.
- AC5: `npm run test` command executes Jest successfully (it may report "no tests found" which is acceptable at this stage).
- AC6: `npm run build` command executes successfully, creating a `dist` directory containing compiled JavaScript output.
- AC7: The `.gitignore` file exists and includes entries for `node_modules/`, `.env`, `dist/`, etc. as specified in the boilerplate.
---
### Story 1.2: Setup Environment Configuration
- **User Story / Goal:** As a developer, I want to establish the environment configuration mechanism using `.env` files, so that secrets and settings (like output paths) can be managed outside of version control, following boilerplate conventions.
- **Detailed Requirements:**
- Verify the `.env.example` file exists (from boilerplate).
- Add an initial configuration variable `OUTPUT_DIR_PATH=./output` to `.env.example`.
- Create the `.env` file locally by copying `.env.example`. Populate `OUTPUT_DIR_PATH` if needed (can keep default).
- Implement a utility module (e.g., `src/config.ts`) that loads environment variables from the `.env` file at application startup.
- The utility should export the loaded configuration values (initially just `OUTPUT_DIR_PATH`).
- Ensure the `.env` file is listed in `.gitignore` and is not committed.
- **Acceptance Criteria (ACs):**
- AC1: Handle `.env` files with native node 22 support, no need for `dotenv`
- AC2: The `.env.example` file exists, is tracked by git, and contains the line `OUTPUT_DIR_PATH=./output`.
- AC3: The `.env` file exists locally but is NOT tracked by git.
- AC4: A configuration module (`src/config.ts` or similar) exists and successfully loads the `OUTPUT_DIR_PATH` value from `.env` when the application starts.
- AC5: The loaded `OUTPUT_DIR_PATH` value is accessible within the application code.
---
### Story 1.3: Implement Basic CLI Entry Point & Execution
- **User Story / Goal:** As a developer, I want a basic `src/index.ts` entry point that can be executed via the boilerplate's `dev` and `start` scripts, providing a working foundation for the application logic.
- **Detailed Requirements:**
- Create the main application entry point file at `src/index.ts`.
- Implement minimal code within `src/index.ts` to:
- Import the configuration loading mechanism (from Story 1.2).
- Log a simple startup message to the console (e.g., "BMad Hacker Daily Digest - Starting Up...").
- (Optional) Log the loaded `OUTPUT_DIR_PATH` to verify config loading.
- Confirm execution using boilerplate scripts.
- **Acceptance Criteria (ACs):**
- AC1: The `src/index.ts` file exists.
- AC2: Running `npm run dev` executes `src/index.ts` via `ts-node` and logs the startup message to the console.
- AC3: Running `npm run build` successfully compiles `src/index.ts` (and any imports) into the `dist` directory.
- AC4: Running `npm start` (after a successful build) executes the compiled code from `dist` and logs the startup message to the console.
---
### Story 1.4: Setup Basic Logging and Output Directory
- **User Story / Goal:** As a developer, I want a basic console logging mechanism and the dynamic creation of a date-stamped output directory, so that the application can provide execution feedback and prepare for storing data artifacts in subsequent epics.
- **Detailed Requirements:**
- Implement a simple, reusable logging utility module (e.g., `src/logger.ts`). Initially, it can wrap `console.log`, `console.warn`, `console.error`.
- Refactor `src/index.ts` to use this `logger` for its startup message(s).
- In `src/index.ts` (or a setup function called by it):
- Retrieve the `OUTPUT_DIR_PATH` from the configuration (loaded in Story 1.2).
- Determine the current date in 'YYYY-MM-DD' format.
- Construct the full path for the date-stamped subdirectory (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`).
- Check if the base output directory exists; if not, create it.
- Check if the date-stamped subdirectory exists; if not, create it recursively. Use Node.js `fs` module (e.g., `fs.mkdirSync(path, { recursive: true })`).
- Log (using the logger) the full path of the output directory being used for the current run (e.g., "Output directory for this run: ./output/2025-05-04").
- **Acceptance Criteria (ACs):**
- AC1: A logger utility module (`src/logger.ts` or similar) exists and is used for console output in `src/index.ts`.
- AC2: Running `npm run dev` or `npm start` logs the startup message via the logger.
- AC3: Running the application creates the base output directory (e.g., `./output` defined in `.env`) if it doesn't already exist.
- AC4: Running the application creates a date-stamped subdirectory (e.g., `./output/2025-05-04`) within the base output directory if it doesn't already exist.
- AC5: The application logs a message indicating the full path to the date-stamped output directory created/used for the current execution.
- AC6: The application exits gracefully after performing these setup steps (for now).

# Epic 2: HN Data Acquisition & Persistence
**Goal:** Implement fetching top 10 stories and their comments (respecting limits) from Algolia HN API, and persist this raw data locally into the date-stamped output directory created in Epic 1. Implement a stage testing utility for fetching.
## Story List
### Story 2.1: Implement Algolia HN API Client
- **User Story / Goal:** As a developer, I want a dedicated client module to interact with the Algolia Hacker News Search API, so that fetching stories and comments is encapsulated, reusable, and uses the required native `Workspace` API.
- **Detailed Requirements:**
- Create a new module: `src/clients/algoliaHNClient.ts`.
- Implement an async function `WorkspaceTopStories` within the client:
- Use native `Workspace` to call the Algolia HN Search API endpoint for front-page stories (e.g., `http://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=10`). Adjust `hitsPerPage` if needed to ensure 10 stories.
- Parse the JSON response.
- Extract required metadata for each story: `objectID` (use as `storyId`), `title`, `url` (article URL), `points`, `num_comments`. Handle potential missing `url` field gracefully (log warning, maybe skip story later if URL needed).
- Construct the `hnUrl` for each story (e.g., `https://news.ycombinator.com/item?id={storyId}`).
- Return an array of structured story objects.
- Implement a separate async function `WorkspaceCommentsForStory` within the client:
- Accept `storyId` and `maxComments` limit as arguments.
- Use native `Workspace` to call the Algolia HN Search API endpoint for comments of a specific story (e.g., `http://hn.algolia.com/api/v1/search?tags=comment,story_{storyId}&hitsPerPage={maxComments}`).
- Parse the JSON response.
- Extract required comment data: `objectID` (use as `commentId`), `comment_text`, `author`, `created_at`.
- Filter out comments where `comment_text` is null or empty. Ensure only up to `maxComments` are returned.
- Return an array of structured comment objects.
- Implement basic error handling using `try...catch` around `Workspace` calls and check `response.ok` status. Log errors using the logger utility from Epic 1.
- Define TypeScript interfaces/types for the expected structures of API responses (stories, comments) and the data returned by the client functions (e.g., `Story`, `Comment`).
- **Acceptance Criteria (ACs):**
- AC1: The module `src/clients/algoliaHNClient.ts` exists and exports `WorkspaceTopStories` and `WorkspaceCommentsForStory` functions.
- AC2: Calling `WorkspaceTopStories` makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of 10 `Story` objects containing the specified metadata.
- AC3: Calling `WorkspaceCommentsForStory` with a valid `storyId` and `maxComments` limit makes a network request to the correct Algolia endpoint and returns a promise resolving to an array of `Comment` objects (up to `maxComments`), filtering out empty ones.
- AC4: Both functions use the native `Workspace` API internally.
- AC5: Network errors or non-successful API responses (e.g., status 4xx, 5xx) are caught and logged using the logger.
- AC6: Relevant TypeScript types (`Story`, `Comment`, etc.) are defined and used within the client module.
---
### Story 2.2: Integrate HN Data Fetching into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the HN data fetching logic into the main application workflow (`src/index.ts`), so that running the app retrieves the top 10 stories and their comments after completing the setup from Epic 1.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts` (or a main async function called by it).
- Import the `algoliaHNClient` functions.
- Import the configuration module to access `MAX_COMMENTS_PER_STORY`.
- After the Epic 1 setup (config load, logger init, output dir creation), call `WorkspaceTopStories()`.
- Log the number of stories fetched.
- Iterate through the array of fetched `Story` objects.
- For each `Story`, call `WorkspaceCommentsForStory()`, passing the `story.storyId` and the configured `MAX_COMMENTS_PER_STORY`.
- Store the fetched comments within the corresponding `Story` object in memory (e.g., add a `comments: Comment[]` property to the `Story` object).
- Log progress using the logger utility (e.g., "Fetched 10 stories.", "Fetching up to X comments for story {storyId}...").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 setup steps followed by fetching stories and then comments for each story.
- AC2: Logs clearly show the start and successful completion of fetching stories, and the start of fetching comments for each of the 10 stories.
- AC3: The configured `MAX_COMMENTS_PER_STORY` value is read from config and used in the calls to `WorkspaceCommentsForStory`.
- AC4: After successful execution, story objects held in memory contain a nested array of fetched comment objects. (Can be verified via debugger or temporary logging).
---
### Story 2.3: Persist Fetched HN Data Locally
- **User Story / Goal:** As a developer, I want to save the fetched HN stories (including their comments) to JSON files in the date-stamped output directory, so that the raw data is persisted locally for subsequent pipeline stages and debugging.
- **Detailed Requirements:**
- Define a consistent JSON structure for the output file content. Example: `{ storyId: "...", title: "...", url: "...", hnUrl: "...", points: ..., fetchedAt: "ISO_TIMESTAMP", comments: [{ commentId: "...", text: "...", author: "...", createdAt: "ISO_TIMESTAMP", ... }, ...] }`. Include a timestamp for when the data was fetched.
- Import Node.js `fs` (specifically `fs.writeFileSync`) and `path` modules.
- In the main workflow (`src/index.ts`), within the loop iterating through stories (after comments have been fetched and added to the story object in Story 2.2):
- Get the full path to the date-stamped output directory (determined in Epic 1).
- Construct the filename for the story's data: `{storyId}_data.json`.
- Construct the full file path using `path.join()`.
- Serialize the complete story object (including comments and fetch timestamp) to a JSON string using `JSON.stringify(storyObject, null, 2)` for readability.
- Write the JSON string to the file using `fs.writeFileSync()`. Use a `try...catch` block for error handling.
- Log (using the logger) the successful persistence of each story's data file or any errors encountered during file writing.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory (e.g., `./output/YYYY-MM-DD/`) contains exactly 10 files named `{storyId}_data.json`.
- AC2: Each JSON file contains valid JSON representing a single story object, including its metadata, fetch timestamp, and an array of its fetched comments, matching the defined structure.
- AC3: The number of comments in each file's `comments` array does not exceed `MAX_COMMENTS_PER_STORY`.
- AC4: Logs indicate that saving data to a file was attempted for each story, reporting success or specific file writing errors.
---
### Story 2.4: Implement Stage Testing Utility for HN Fetching
- **User Story / Goal:** As a developer, I want a separate, executable script that *only* performs the HN data fetching and persistence, so I can test and trigger this stage independently of the full pipeline.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/fetch_hn_data.ts`.
- This script should perform the essential setup required for this stage: initialize logger, load configuration (`.env`), determine and create output directory (reuse or replicate logic from Epic 1 / `src/index.ts`).
- The script should then execute the core logic of fetching stories via `algoliaHNClient.fetchTopStories`, fetching comments via `algoliaHNClient.fetchCommentsForStory` (using loaded config for limit), and persisting the results to JSON files using `fs.writeFileSync` (replicating logic from Story 2.3).
- The script should log its progress using the logger utility.
- Add a new script command to `package.json` under `"scripts"`: `"stage:fetch": "ts-node src/stages/fetch_hn_data.ts"`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/fetch_hn_data.ts` exists.
- AC2: The script `stage:fetch` is defined in `package.json`'s `scripts` section.
- AC3: Running `npm run stage:fetch` executes successfully, performing only the setup, fetch, and persist steps.
- AC4: Running `npm run stage:fetch` creates the same 10 `{storyId}_data.json` files in the correct date-stamped output directory as running the main `npm run dev` command (at the current state of development).
- AC5: Logs generated by `npm run stage:fetch` reflect only the fetching and persisting steps, not subsequent pipeline stages.

# Epic 3: Article Scraping & Persistence
**Goal:** Implement a best-effort article scraping mechanism to fetch and extract plain text content from the external URLs associated with fetched HN stories. Handle failures gracefully and persist successfully scraped text locally. Implement a stage testing utility for scraping.
## Story List
### Story 3.1: Implement Basic Article Scraper Module
- **User Story / Goal:** As a developer, I want a module that attempts to fetch HTML from a URL and extract the main article text using basic methods, handling common failures gracefully, so article content can be prepared for summarization.
- **Detailed Requirements:**
- Create a new module: `src/scraper/articleScraper.ts`.
- Add a suitable HTML parsing/extraction library dependency (e.g., `@extractus/article-extractor` recommended for simplicity, or `cheerio` for more control). Run `npm install @extractus/article-extractor --save-prod` (or chosen alternative).
- Implement an async function `scrapeArticle(url: string): Promise<string | null>` within the module.
- Inside the function:
- Use native `Workspace` to retrieve content from the `url`. Set a reasonable timeout (e.g., 10-15 seconds). Include a `User-Agent` header to mimic a browser.
- Handle potential `Workspace` errors (network errors, timeouts) using `try...catch`.
- Check the `response.ok` status. If not okay, log error and return `null`.
- Check the `Content-Type` header of the response. If it doesn't indicate HTML (e.g., does not include `text/html`), log warning and return `null`.
- If HTML is received, attempt to extract the main article text using the chosen library (`article-extractor` preferred).
- Wrap the extraction logic in a `try...catch` to handle library-specific errors.
- Return the extracted plain text string if successful. Ensure it's just text, not HTML markup.
- Return `null` if extraction fails or results in empty content.
- Log all significant events, errors, or reasons for returning null (e.g., "Scraping URL...", "Fetch failed:", "Non-HTML content type:", "Extraction failed:", "Successfully extracted text") using the logger utility.
- Define TypeScript types/interfaces as needed.
- **Acceptance Criteria (ACs):**
- AC1: The `articleScraper.ts` module exists and exports the `scrapeArticle` function.
- AC2: The chosen scraping library (e.g., `@extractus/article-extractor`) is added to `dependencies` in `package.json`.
- AC3: `scrapeArticle` uses native `Workspace` with a timeout and User-Agent header.
- AC4: `scrapeArticle` correctly handles fetch errors, non-OK responses, and non-HTML content types by logging and returning `null`.
- AC5: `scrapeArticle` uses the chosen library to attempt text extraction from valid HTML content.
- AC6: `scrapeArticle` returns the extracted plain text on success, and `null` on any failure (fetch, non-HTML, extraction error, empty result).
- AC7: Relevant logs are produced for success, failure modes, and errors encountered during the process.

### Story 3.2: Integrate Article Scraping into Main Workflow
- **User Story / Goal:** As a developer, I want to integrate the article scraper into the main workflow (`src/index.ts`), attempting to scrape the article for each HN story that has a valid URL, after fetching its data.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import the `scrapeArticle` function from `src/scraper/articleScraper.ts`.
- Within the main loop iterating through the fetched stories (after comments are fetched in Epic 2):
- Check if `story.url` exists and appears to be a valid HTTP/HTTPS URL. A simple check for starting with `http://` or `https://` is sufficient.
- If the URL is missing or invalid, log a warning ("Skipping scraping for story {storyId}: Missing or invalid URL") and proceed to the next story's processing step.
- If a valid URL exists, log ("Attempting to scrape article for story {storyId} from {story.url}").
- Call `await scrapeArticle(story.url)`.
- Store the result (the extracted text string or `null`) in memory, associated with the story object (e.g., add property `articleContent: string | null`).
- Log the outcome clearly (e.g., "Successfully scraped article for story {storyId}", "Failed to scrape article for story {storyId}").
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes Epic 1 & 2 steps, and then attempts article scraping for stories with valid URLs.
- AC2: Stories with missing or invalid URLs are skipped, and a corresponding log message is generated.
- AC3: For stories with valid URLs, the `scrapeArticle` function is called.
- AC4: Logs clearly indicate the start and success/failure outcome of the scraping attempt for each relevant story.
- AC5: Story objects held in memory after this stage contain an `articleContent` property holding the scraped text (string) or `null` if scraping was skipped or failed.
---
### Story 3.3: Persist Scraped Article Text Locally
- **User Story / Goal:** As a developer, I want to save successfully scraped article text to a separate local file for each story, so that the text content is available as input for the summarization stage.
- **Detailed Requirements:**
- Import Node.js `fs` and `path` modules if not already present in `src/index.ts`.
- In the main workflow (`src/index.ts`), immediately after a successful call to `scrapeArticle` for a story (where the result is a non-null string):
- Retrieve the full path to the current date-stamped output directory.
- Construct the filename: `{storyId}_article.txt`.
- Construct the full file path using `path.join()`.
- Get the successfully scraped article text string (`articleContent`).
- Use `fs.writeFileSync(fullPath, articleContent, 'utf-8')` to save the text to the file. Wrap in `try...catch` for file system errors.
- Log the successful saving of the file (e.g., "Saved scraped article text to {filename}") or any file writing errors encountered.
- Ensure *no* `_article.txt` file is created if `scrapeArticle` returned `null` (due to skipping or failure).
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains `_article.txt` files *only* for those stories where `scrapeArticle` succeeded and returned text content.
- AC2: The name of each article text file is `{storyId}_article.txt`.
- AC3: The content of each `_article.txt` file is the plain text string returned by `scrapeArticle`.
- AC4: Logs confirm the successful writing of each `_article.txt` file or report specific file writing errors.
- AC5: No empty `_article.txt` files are created. Files only exist if scraping was successful.
---
### Story 3.4: Implement Stage Testing Utility for Scraping
- **User Story / Goal:** As a developer, I want a separate script/command to test the article scraping logic using HN story data from local files, allowing independent testing and debugging of the scraper.
- **Detailed Requirements:**
- Create a new standalone script file: `src/stages/scrape_articles.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `scrapeArticle`.
- The script should:
- Initialize the logger.
- Load configuration (to get `OUTPUT_DIR_PATH`).
- Determine the target date-stamped directory path (e.g., `${OUTPUT_DIR_PATH}/YYYY-MM-DD`, using the current date or potentially an optional CLI argument). Ensure this directory exists.
- Read the directory contents and identify all `{storyId}_data.json` files.
- For each `_data.json` file found:
- Read and parse the JSON content.
- Extract the `storyId` and `url`.
- If a valid `url` exists, call `await scrapeArticle(url)`.
- If scraping succeeds (returns text), save the text to `{storyId}_article.txt` in the same directory (using logic from Story 3.3). Overwrite if the file exists.
- Log the progress and outcome (skip/success/fail) for each story processed.
- Add a new script command to `package.json`: `"stage:scrape": "ts-node src/stages/scrape_articles.ts"`. Consider adding argument parsing later if needed to specify a date/directory.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/scrape_articles.ts` exists.
- AC2: The script `stage:scrape` is defined in `package.json`.
- AC3: Running `npm run stage:scrape` (assuming a directory with `_data.json` files exists from a previous `stage:fetch` run) reads these files.
- AC4: The script calls `scrapeArticle` for stories with valid URLs found in the JSON files.
- AC5: The script creates/updates `{storyId}_article.txt` files in the target directory corresponding to successfully scraped articles.
- AC6: The script logs its actions (reading files, attempting scraping, saving results) for each story ID processed.
- AC7: The script operates solely based on local `_data.json` files and fetching from external article URLs; it does not call the Algolia HN API.

# Epic 4: LLM Summarization & Persistence
**Goal:** Integrate with the configured local Ollama instance to generate summaries for successfully scraped article text and fetched comments. Persist these summaries locally. Implement a stage testing utility for summarization.
## Story List
### Story 4.1: Implement Ollama Client Module
- **User Story / Goal:** As a developer, I want a client module to interact with the configured Ollama API endpoint via HTTP, handling requests and responses for text generation, so that summaries can be generated programmatically.
- **Detailed Requirements:**
- **Prerequisite:** Ensure a local Ollama instance is installed and running, accessible via the URL defined in `.env` (`OLLAMA_ENDPOINT_URL`), and that the model specified in `.env` (`OLLAMA_MODEL`) has been downloaded (e.g., via `ollama pull model_name`). Instructions for this setup should be in the project README.
- Create a new module: `src/clients/ollamaClient.ts`.
- Implement an async function `generateSummary(promptTemplate: string, content: string): Promise<string | null>`. *(Note: Parameter name changed for clarity)*
- Add configuration variables `OLLAMA_ENDPOINT_URL` (e.g., `http://localhost:11434`) and `OLLAMA_MODEL` (e.g., `llama3`) to `.env.example`. Ensure they are loaded via the config module (`src/utils/config.ts`). Update local `.env` with actual values. Add optional `OLLAMA_TIMEOUT_MS` to `.env.example` with a default like `120000`.
- Inside `generateSummary`:
- Construct the full prompt string using the `promptTemplate` and the provided `content` (e.g., replacing a placeholder like `{Content Placeholder}` in the template, or simple concatenation if templates are basic).
- Construct the Ollama API request payload (JSON): `{ model: configured_model, prompt: full_prompt, stream: false }`. Refer to Ollama `/api/generate` documentation and `docs/data-models.md`.
- Use native `Workspace` to send a POST request to the configured Ollama endpoint + `/api/generate`. Set appropriate headers (`Content-Type: application/json`). Use the configured `OLLAMA_TIMEOUT_MS` or a reasonable default (e.g., 2 minutes).
- Handle `Workspace` errors (network, timeout) using `try...catch`.
- Check `response.ok`. If not OK, log the status/error and return `null`.
- Parse the JSON response from Ollama. Extract the generated text (typically in the `response` field). Refer to `docs/data-models.md`.
- Check for potential errors within the Ollama response structure itself (e.g., an `error` field).
- Return the extracted summary string on success. Return `null` on any failure.
- Log key events: initiating request (mention model), receiving response, success, failure reasons, potentially request/response time using the logger.
- Define necessary TypeScript types for the Ollama request payload and expected response structure in `src/types/ollama.ts` (referenced in `docs/data-models.md`).
- **Acceptance Criteria (ACs):**
- AC1: The `ollamaClient.ts` module exists and exports `generateSummary`.
- AC2: `OLLAMA_ENDPOINT_URL` and `OLLAMA_MODEL` are defined in `.env.example`, loaded via config, and used by the client. Optional `OLLAMA_TIMEOUT_MS` is handled.
- AC3: `generateSummary` sends a correctly formatted POST request (model, full prompt based on template and content, stream:false) to the configured Ollama endpoint/path using native `Workspace`.
- AC4: Network errors, timeouts, and non-OK API responses are handled gracefully, logged, and result in a `null` return (given the Prerequisite Ollama service is running).
- AC5: A successful Ollama response is parsed correctly, the generated text is extracted, and returned as a string.
* AC6: Unexpected Ollama response formats or internal errors (e.g., `{"error": "..."}`) are handled, logged, and result in a `null` return.
* AC7: Logs provide visibility into the client's interaction with the Ollama API.
---
### Story 4.2: Define Summarization Prompts
* **User Story / Goal:** As a developer, I want standardized base prompts for generating article summaries and HN discussion summaries documented centrally, ensuring consistent instructions are sent to the LLM.
* **Detailed Requirements:**
* Define two standardized base prompts (`ARTICLE_SUMMARY_PROMPT`, `DISCUSSION_SUMMARY_PROMPT`) **and document them in `docs/prompts.md`**.
* Ensure these prompts are accessible within the application code, for example, by defining them as exported constants in a dedicated module like `src/utils/prompts.ts`, which reads from or mirrors the content in `docs/prompts.md`.
* **Acceptance Criteria (ACs):**
* AC1: The `ARTICLE_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC2: The `DISCUSSION_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC3: The prompt texts documented in `docs/prompts.md` are available as constants or variables within the application code (e.g., via `src/utils/prompts.ts`) for use by the Ollama client integration.
---
### Story 4.3: Integrate Summarization into Main Workflow
* **User Story / Goal:** As a developer, I want to integrate the Ollama client into the main workflow to generate summaries for each story's scraped article text (if available) and fetched comments, using centrally defined prompts and handling potential comment length limits.
* **Detailed Requirements:**
* Modify the main execution flow in `src/index.ts` or `src/core/pipeline.ts`.
* Import `ollamaClient.generateSummary` and the prompt constants/variables (e.g., from `src/utils/prompts.ts`, which reflect `docs/prompts.md`).
* Load the optional `MAX_COMMENT_CHARS_FOR_SUMMARY` configuration value from `.env` via the config utility.
* Within the main loop iterating through stories (after article scraping/persistence in Epic 3):
* **Article Summary Generation:**
* Check if the `story` object has non-null `articleContent`.
* If yes: log "Attempting article summarization for story {storyId}", call `await generateSummary(ARTICLE_SUMMARY_PROMPT, story.articleContent)`, store the result (string or null) as `story.articleSummary`, log success/failure.
* If no: set `story.articleSummary = null`, log "Skipping article summarization: No content".
* **Discussion Summary Generation:**
* Check if the `story` object has a non-empty `comments` array.
* If yes:
* Format the `story.comments` array into a single text block suitable for the LLM prompt (e.g., concatenating `comment.text` with separators like `---`).
* **Check truncation limit:** If `MAX_COMMENT_CHARS_FOR_SUMMARY` is configured to a positive number and the `formattedCommentsText` length exceeds it, truncate `formattedCommentsText` to the limit and log a warning: "Comment text truncated to {limit} characters for summarization for story {storyId}".
* Log "Attempting discussion summarization for story {storyId}".
* Call `await generateSummary(DISCUSSION_SUMMARY_PROMPT, formattedCommentsText)`. *(Pass the potentially truncated text)*
* Store the result (string or null) as `story.discussionSummary`. Log success/failure.
* If no: set `story.discussionSummary = null`, log "Skipping discussion summarization: No comments".
* **Acceptance Criteria (ACs):**
* AC1: Running `npm run dev` executes steps from Epics 1-3, then attempts summarization using the Ollama client.
* AC2: Article summary is attempted only if `articleContent` exists for a story.
* AC3: Discussion summary is attempted only if `comments` exist for a story.
* AC4: `generateSummary` is called with the correct prompts (sourced consistently with `docs/prompts.md`) and corresponding content (article text or formatted/potentially truncated comments).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and comment text exceeds it, the text passed to `generateSummary` is truncated, and a warning is logged.
* AC6: Logs clearly indicate the start, success, or failure (including null returns from the client) for both article and discussion summarization attempts per story.
* AC7: Story objects in memory now contain `articleSummary` (string/null) and `discussionSummary` (string/null) properties.
---
### Story 4.4: Persist Generated Summaries Locally
*(No changes needed for this story based on recent decisions)*
- **User Story / Goal:** As a developer, I want to save the generated article and discussion summaries (or null placeholders) to a local JSON file for each story, making them available for the email assembly stage.
- **Detailed Requirements:**
- Define the structure for the summary output file: `{storyId}_summary.json`. Content example: `{ "storyId": "...", "articleSummary": "...", "discussionSummary": "...", "summarizedAt": "ISO_TIMESTAMP" }`. Note that `articleSummary` and `discussionSummary` can be `null`.
- Import `fs` and `path` in `src/index.ts` or `src/core/pipeline.ts` if needed.
- In the main workflow loop, after *both* summarization attempts (article and discussion) for a story are complete:
- Create a summary result object containing `storyId`, `articleSummary` (string or null), `discussionSummary` (string or null), and the current ISO timestamp (`new Date().toISOString()`). Add this timestamp to the in-memory `story` object as well (`story.summarizedAt`).
- Get the full path to the date-stamped output directory.
- Construct the filename: `{storyId}_summary.json`.
- Construct the full file path using `path.join()`.
- Serialize the summary result object to JSON (`JSON.stringify(..., null, 2)`).
- Use `fs.writeFileSync` to save the JSON to the file, wrapping in `try...catch`.
- Log the successful saving of the summary file or any file writing errors.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains 10 files named `{storyId}_summary.json`.
- AC2: Each `_summary.json` file contains valid JSON adhering to the defined structure.
- AC3: The `articleSummary` field contains the generated summary string if successful, otherwise `null`.
- AC4: The `discussionSummary` field contains the generated summary string if successful, otherwise `null`.
- AC5: A valid ISO timestamp is present in the `summarizedAt` field.
- AC6: Logs confirm successful writing of each summary file or report file system errors.
---
### Story 4.5: Implement Stage Testing Utility for Summarization
*(Changes needed to reflect prompt sourcing and optional truncation)*
* **User Story / Goal:** As a developer, I want a separate script/command to test the LLM summarization logic using locally persisted data (HN comments, scraped article text), allowing independent testing of prompts and Ollama interaction.
* **Detailed Requirements:**
* Create a new standalone script file: `src/stages/summarize_content.ts`.
* Import necessary modules: `fs`, `path`, `logger`, `config`, `ollamaClient`, prompt constants (e.g., from `src/utils/prompts.ts`).
* The script should:
* Initialize logger, load configuration (Ollama endpoint/model, output dir, **optional `MAX_COMMENT_CHARS_FOR_SUMMARY`**).
* Determine target date-stamped directory path.
* Find all `{storyId}_data.json` files in the directory.
* For each `storyId` found:
* Read `{storyId}_data.json` to get comments. Format them into a single text block.
* *Attempt* to read `{storyId}_article.txt`. Handle file-not-found gracefully. Store content or null.
* Call `ollamaClient.generateSummary` for article text (if not null) using `ARTICLE_SUMMARY_PROMPT`.
* **Apply truncation logic:** If comments exist, check `MAX_COMMENT_CHARS_FOR_SUMMARY` and truncate the formatted comment text block if needed, logging a warning.
* Call `ollamaClient.generateSummary` for formatted comments (if comments exist) using `DISCUSSION_SUMMARY_PROMPT` *(passing potentially truncated text)*.
* Construct the summary result object (with summaries or nulls, and timestamp).
* Save the result object to `{storyId}_summary.json` in the same directory (using logic from Story 4.4), overwriting if exists.
* Log progress (reading files, calling Ollama, truncation warnings, saving results) for each story ID.
* Add script to `package.json`: `"stage:summarize": "ts-node src/stages/summarize_content.ts"`.
* **Acceptance Criteria (ACs):**
* AC1: The file `src/stages/summarize_content.ts` exists.
* AC2: The script `stage:summarize` is defined in `package.json`.
* AC3: Running `npm run stage:summarize` (after `stage:fetch` and `stage:scrape` runs) reads `_data.json` and attempts to read `_article.txt` files from the target directory.
* AC4: The script calls the `ollamaClient` with correct prompts (sourced consistently with `docs/prompts.md`) and content derived *only* from the local files (requires Ollama service running per Story 4.1 prerequisite).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and applicable, comment text is truncated before calling the client, and a warning is logged.
* AC6: The script creates/updates `{storyId}_summary.json` files in the target directory reflecting the results of the Ollama calls (summaries or nulls).
* AC7: Logs show the script processing each story ID found locally, interacting with Ollama, and saving results.
* AC8: The script does not call Algolia API or the article scraper module.

**Goal:** Integrate with the configured local Ollama instance to generate summaries for successfully scraped article text and fetched comments. Persist these summaries locally. Implement a stage testing utility for summarization.
## Story List
### Story 4.1: Implement Ollama Client Module
- **User Story / Goal:** As a developer, I want a client module to interact with the configured Ollama API endpoint via HTTP, handling requests and responses for text generation, so that summaries can be generated programmatically.
- **Detailed Requirements:**
- **Prerequisite:** Ensure a local Ollama instance is installed and running, accessible via the URL defined in `.env` (`OLLAMA_ENDPOINT_URL`), and that the model specified in `.env` (`OLLAMA_MODEL`) has been downloaded (e.g., via `ollama pull model_name`). Instructions for this setup should be in the project README.
- Create a new module: `src/clients/ollamaClient.ts`.
- Implement an async function `generateSummary(promptTemplate: string, content: string): Promise<string | null>`. *(Note: Parameter name changed for clarity)*
- Add configuration variables `OLLAMA_ENDPOINT_URL` (e.g., `http://localhost:11434`) and `OLLAMA_MODEL` (e.g., `llama3`) to `.env.example`. Ensure they are loaded via the config module (`src/utils/config.ts`). Update local `.env` with actual values. Add optional `OLLAMA_TIMEOUT_MS` to `.env.example` with a default like `120000`.
- Inside `generateSummary`:
- Construct the full prompt string using the `promptTemplate` and the provided `content` (e.g., replacing a placeholder like `{Content Placeholder}` in the template, or simple concatenation if templates are basic).
- Construct the Ollama API request payload (JSON): `{ model: configured_model, prompt: full_prompt, stream: false }`. Refer to Ollama `/api/generate` documentation and `docs/data-models.md`.
- Use native `Workspace` to send a POST request to the configured Ollama endpoint + `/api/generate`. Set appropriate headers (`Content-Type: application/json`). Use the configured `OLLAMA_TIMEOUT_MS` or a reasonable default (e.g., 2 minutes).
- Handle `Workspace` errors (network, timeout) using `try...catch`.
- Check `response.ok`. If not OK, log the status/error and return `null`.
- Parse the JSON response from Ollama. Extract the generated text (typically in the `response` field). Refer to `docs/data-models.md`.
- Check for potential errors within the Ollama response structure itself (e.g., an `error` field).
- Return the extracted summary string on success. Return `null` on any failure.
- Log key events: initiating request (mention model), receiving response, success, failure reasons, potentially request/response time using the logger.
- Define necessary TypeScript types for the Ollama request payload and expected response structure in `src/types/ollama.ts` (referenced in `docs/data-models.md`).
- **Acceptance Criteria (ACs):**
- AC1: The `ollamaClient.ts` module exists and exports `generateSummary`.
- AC2: `OLLAMA_ENDPOINT_URL` and `OLLAMA_MODEL` are defined in `.env.example`, loaded via config, and used by the client. Optional `OLLAMA_TIMEOUT_MS` is handled.
- AC3: `generateSummary` sends a correctly formatted POST request (model, full prompt based on template and content, stream:false) to the configured Ollama endpoint/path using native `Workspace`.
- AC4: Network errors, timeouts, and non-OK API responses are handled gracefully, logged, and result in a `null` return (given the Prerequisite Ollama service is running).
- AC5: A successful Ollama response is parsed correctly, the generated text is extracted, and returned as a string.
* AC6: Unexpected Ollama response formats or internal errors (e.g., `{"error": "..."}`) are handled, logged, and result in a `null` return.
* AC7: Logs provide visibility into the client's interaction with the Ollama API.
---
### Story 4.2: Define Summarization Prompts
* **User Story / Goal:** As a developer, I want standardized base prompts for generating article summaries and HN discussion summaries documented centrally, ensuring consistent instructions are sent to the LLM.
* **Detailed Requirements:**
* Define two standardized base prompts (`ARTICLE_SUMMARY_PROMPT`, `DISCUSSION_SUMMARY_PROMPT`) **and document them in `docs/prompts.md`**.
* Ensure these prompts are accessible within the application code, for example, by defining them as exported constants in a dedicated module like `src/utils/prompts.ts`, which reads from or mirrors the content in `docs/prompts.md`.
* **Acceptance Criteria (ACs):**
* AC1: The `ARTICLE_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC2: The `DISCUSSION_SUMMARY_PROMPT` text is defined in `docs/prompts.md` with appropriate instructional content.
* AC3: The prompt texts documented in `docs/prompts.md` are available as constants or variables within the application code (e.g., via `src/utils/prompts.ts`) for use by the Ollama client integration.
---
### Story 4.3: Integrate Summarization into Main Workflow
* **User Story / Goal:** As a developer, I want to integrate the Ollama client into the main workflow to generate summaries for each story's scraped article text (if available) and fetched comments, using centrally defined prompts and handling potential comment length limits.
* **Detailed Requirements:**
* Modify the main execution flow in `src/index.ts` or `src/core/pipeline.ts`.
* Import `ollamaClient.generateSummary` and the prompt constants/variables (e.g., from `src/utils/prompts.ts`, which reflect `docs/prompts.md`).
* Load the optional `MAX_COMMENT_CHARS_FOR_SUMMARY` configuration value from `.env` via the config utility.
* Within the main loop iterating through stories (after article scraping/persistence in Epic 3):
* **Article Summary Generation:**
* Check if the `story` object has non-null `articleContent`.
* If yes: log "Attempting article summarization for story {storyId}", call `await generateSummary(ARTICLE_SUMMARY_PROMPT, story.articleContent)`, store the result (string or null) as `story.articleSummary`, log success/failure.
* If no: set `story.articleSummary = null`, log "Skipping article summarization: No content".
* **Discussion Summary Generation:**
* Check if the `story` object has a non-empty `comments` array.
* If yes:
* Format the `story.comments` array into a single text block suitable for the LLM prompt (e.g., concatenating `comment.text` with separators like `---`).
* **Check truncation limit:** If `MAX_COMMENT_CHARS_FOR_SUMMARY` is configured to a positive number and the `formattedCommentsText` length exceeds it, truncate `formattedCommentsText` to the limit and log a warning: "Comment text truncated to {limit} characters for summarization for story {storyId}".
* Log "Attempting discussion summarization for story {storyId}".
* Call `await generateSummary(DISCUSSION_SUMMARY_PROMPT, formattedCommentsText)`. *(Pass the potentially truncated text)*
* Store the result (string or null) as `story.discussionSummary`. Log success/failure.
* If no: set `story.discussionSummary = null`, log "Skipping discussion summarization: No comments".
* **Acceptance Criteria (ACs):**
* AC1: Running `npm run dev` executes steps from Epics 1-3, then attempts summarization using the Ollama client.
* AC2: Article summary is attempted only if `articleContent` exists for a story.
* AC3: Discussion summary is attempted only if `comments` exist for a story.
* AC4: `generateSummary` is called with the correct prompts (sourced consistently with `docs/prompts.md`) and corresponding content (article text or formatted/potentially truncated comments).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and comment text exceeds it, the text passed to `generateSummary` is truncated, and a warning is logged.
* AC6: Logs clearly indicate the start, success, or failure (including null returns from the client) for both article and discussion summarization attempts per story.
* AC7: Story objects in memory now contain `articleSummary` (string/null) and `discussionSummary` (string/null) properties.
---
### Story 4.4: Persist Generated Summaries Locally
*(No changes needed for this story based on recent decisions)*
- **User Story / Goal:** As a developer, I want to save the generated article and discussion summaries (or null placeholders) to a local JSON file for each story, making them available for the email assembly stage.
- **Detailed Requirements:**
- Define the structure for the summary output file: `{storyId}_summary.json`. Content example: `{ "storyId": "...", "articleSummary": "...", "discussionSummary": "...", "summarizedAt": "ISO_TIMESTAMP" }`. Note that `articleSummary` and `discussionSummary` can be `null`.
- Import `fs` and `path` in `src/index.ts` or `src/core/pipeline.ts` if needed.
- In the main workflow loop, after *both* summarization attempts (article and discussion) for a story are complete:
- Create a summary result object containing `storyId`, `articleSummary` (string or null), `discussionSummary` (string or null), and the current ISO timestamp (`new Date().toISOString()`). Add this timestamp to the in-memory `story` object as well (`story.summarizedAt`).
- Get the full path to the date-stamped output directory.
- Construct the filename: `{storyId}_summary.json`.
- Construct the full file path using `path.join()`.
- Serialize the summary result object to JSON (`JSON.stringify(..., null, 2)`).
- Use `fs.writeFileSync` to save the JSON to the file, wrapping in `try...catch`.
- Log the successful saving of the summary file or any file writing errors.
- **Acceptance Criteria (ACs):**
- AC1: After running `npm run dev`, the date-stamped output directory contains 10 files named `{storyId}_summary.json`.
- AC2: Each `_summary.json` file contains valid JSON adhering to the defined structure.
- AC3: The `articleSummary` field contains the generated summary string if successful, otherwise `null`.
- AC4: The `discussionSummary` field contains the generated summary string if successful, otherwise `null`.
- AC5: A valid ISO timestamp is present in the `summarizedAt` field.
- AC6: Logs confirm successful writing of each summary file or report file system errors.
---
### Story 4.5: Implement Stage Testing Utility for Summarization
*(Changes needed to reflect prompt sourcing and optional truncation)*
* **User Story / Goal:** As a developer, I want a separate script/command to test the LLM summarization logic using locally persisted data (HN comments, scraped article text), allowing independent testing of prompts and Ollama interaction.
* **Detailed Requirements:**
* Create a new standalone script file: `src/stages/summarize_content.ts`.
* Import necessary modules: `fs`, `path`, `logger`, `config`, `ollamaClient`, prompt constants (e.g., from `src/utils/prompts.ts`).
* The script should:
* Initialize logger, load configuration (Ollama endpoint/model, output dir, **optional `MAX_COMMENT_CHARS_FOR_SUMMARY`**).
* Determine target date-stamped directory path.
* Find all `{storyId}_data.json` files in the directory.
* For each `storyId` found:
* Read `{storyId}_data.json` to get comments. Format them into a single text block.
* *Attempt* to read `{storyId}_article.txt`. Handle file-not-found gracefully. Store content or null.
* Call `ollamaClient.generateSummary` for article text (if not null) using `ARTICLE_SUMMARY_PROMPT`.
* **Apply truncation logic:** If comments exist, check `MAX_COMMENT_CHARS_FOR_SUMMARY` and truncate the formatted comment text block if needed, logging a warning.
* Call `ollamaClient.generateSummary` for formatted comments (if comments exist) using `DISCUSSION_SUMMARY_PROMPT` *(passing potentially truncated text)*.
* Construct the summary result object (with summaries or nulls, and timestamp).
* Save the result object to `{storyId}_summary.json` in the same directory (using logic from Story 4.4), overwriting if exists.
* Log progress (reading files, calling Ollama, truncation warnings, saving results) for each story ID.
* Add script to `package.json`: `"stage:summarize": "ts-node src/stages/summarize_content.ts"`.
* **Acceptance Criteria (ACs):**
* AC1: The file `src/stages/summarize_content.ts` exists.
* AC2: The script `stage:summarize` is defined in `package.json`.
* AC3: Running `npm run stage:summarize` (after `stage:fetch` and `stage:scrape` runs) reads `_data.json` and attempts to read `_article.txt` files from the target directory.
* AC4: The script calls the `ollamaClient` with correct prompts (sourced consistently with `docs/prompts.md`) and content derived *only* from the local files (requires Ollama service running per Story 4.1 prerequisite).
* AC5: If `MAX_COMMENT_CHARS_FOR_SUMMARY` is set and applicable, comment text is truncated before calling the client, and a warning is logged.
* AC6: The script creates/updates `{storyId}_summary.json` files in the target directory reflecting the results of the Ollama calls (summaries or nulls).
* AC7: Logs show the script processing each story ID found locally, interacting with Ollama, and saving results.
* AC8: The script does not call Algolia API or the article scraper module.

# Epic 5: Digest Assembly & Email Dispatch
**Goal:** Assemble the collected story data and summaries from local files, format them into a readable HTML email digest, and send the email using Nodemailer with configured credentials. Implement a stage testing utility for emailing with a dry-run option.
## Story List
### Story 5.1: Implement Email Content Assembler
- **User Story / Goal:** As a developer, I want a module that reads the persisted story metadata (`_data.json`) and summaries (`_summary.json`) from a specified directory, consolidating the necessary information needed to render the email digest.
- **Detailed Requirements:**
- Create a new module: `src/email/contentAssembler.ts`.
- Define a TypeScript type/interface `DigestData` representing the data needed per story for the email template: `{ storyId: string, title: string, hnUrl: string, articleUrl: string | null, articleSummary: string | null, discussionSummary: string | null }`.
- Implement an async function `assembleDigestData(dateDirPath: string): Promise<DigestData[]>`.
- The function should:
- Use Node.js `fs` to read the contents of the `dateDirPath`.
- Identify all files matching the pattern `{storyId}_data.json`.
- For each `storyId` found:
- Read and parse the `{storyId}_data.json` file. Extract `title`, `hnUrl`, and `url` (use as `articleUrl`). Handle potential file read/parse errors gracefully (log and skip story).
- Attempt to read and parse the corresponding `{storyId}_summary.json` file. Handle file-not-found or parse errors gracefully (treat `articleSummary` and `discussionSummary` as `null`).
- Construct a `DigestData` object for the story, including the extracted metadata and summaries (or nulls).
- Collect all successfully constructed `DigestData` objects into an array.
- Return the array. It should ideally contain 10 items if all previous stages succeeded.
- Log progress (e.g., "Assembling digest data from directory...", "Processing story {storyId}...") and any errors encountered during file processing using the logger.
- **Acceptance Criteria (ACs):**
- AC1: The `contentAssembler.ts` module exists and exports `assembleDigestData` and the `DigestData` type.
- AC2: `assembleDigestData` correctly reads `_data.json` files from the provided directory path.
- AC3: It attempts to read corresponding `_summary.json` files, correctly handling cases where the summary file might be missing or unparseable (resulting in null summaries for that story).
- AC4: The function returns a promise resolving to an array of `DigestData` objects, populated with data extracted from the files.
- AC5: Errors during file reading or JSON parsing are logged, and the function returns data for successfully processed stories.
---
### Story 5.2: Create HTML Email Template & Renderer
- **User Story / Goal:** As a developer, I want a basic HTML email template and a function to render it with the assembled digest data, producing the final HTML content for the email body.
- **Detailed Requirements:**
- Define the HTML structure. This can be done using template literals within a function or potentially using a simple template file (e.g., `src/email/templates/digestTemplate.html`) and `fs.readFileSync`. Template literals are simpler for MVP.
- Create a function `renderDigestHtml(data: DigestData[], digestDate: string): string` (e.g., in `src/email/contentAssembler.ts` or a new `templater.ts`).
- The function should generate an HTML string with:
- A suitable title in the body (e.g., `<h1>Hacker News Top 10 Summaries for ${digestDate}</h1>`).
- A loop through the `data` array.
- For each `story` in `data`:
- Display `<h2><a href="${story.articleUrl || story.hnUrl}">${story.title}</a></h2>`.
- Display `<p><a href="${story.hnUrl}">View HN Discussion</a></p>`.
- Conditionally display `<h3>Article Summary</h3><p>${story.articleSummary}</p>` *only if* `story.articleSummary` is not null/empty.
- Conditionally display `<h3>Discussion Summary</h3><p>${story.discussionSummary}</p>` *only if* `story.discussionSummary` is not null/empty.
- Include a separator (e.g., `<hr style="margin-top: 20px; margin-bottom: 20px;">`).
- Use basic inline CSS for minimal styling (margins, etc.) to ensure readability. Avoid complex layouts.
- Return the complete HTML document as a string.
- **Acceptance Criteria (ACs):**
- AC1: A function `renderDigestHtml` exists that accepts the digest data array and a date string.
- AC2: The function returns a single, complete HTML string.
- AC3: The generated HTML includes a title with the date and correctly iterates through the story data.
- AC4: For each story, the HTML displays the linked title, HN link, and conditionally displays the article and discussion summaries with headings.
- AC5: Basic separators and margins are used for readability. The HTML is simple and likely to render reasonably in most email clients.
---
### Story 5.3: Implement Nodemailer Email Sender
- **User Story / Goal:** As a developer, I want a module to send the generated HTML email using Nodemailer, configured with credentials stored securely in the environment file.
- **Detailed Requirements:**
- Add Nodemailer dependencies: `npm install nodemailer @types/nodemailer --save-prod`.
- Add required configuration variables to `.env.example` (and local `.env`): `EMAIL_HOST`, `EMAIL_PORT` (e.g., 587), `EMAIL_SECURE` (e.g., `false` for STARTTLS on 587, `true` for 465), `EMAIL_USER`, `EMAIL_PASS`, `EMAIL_FROM` (e.g., `"Your Name <you@example.com>"`), `EMAIL_RECIPIENTS` (comma-separated list).
- Create a new module: `src/email/emailSender.ts`.
- Implement an async function `sendDigestEmail(subject: string, htmlContent: string): Promise<boolean>`.
- Inside the function:
- Load the `EMAIL_*` variables from the config module.
- Create a Nodemailer transporter using `nodemailer.createTransport` with the loaded config (host, port, secure flag, auth: { user, pass }).
- Verify transporter configuration using `transporter.verify()` (optional but recommended). Log verification success/failure.
- Parse the `EMAIL_RECIPIENTS` string into an array or comma-separated string suitable for the `to` field.
- Define the `mailOptions`: `{ from: EMAIL_FROM, to: parsedRecipients, subject: subject, html: htmlContent }`.
- Call `await transporter.sendMail(mailOptions)`.
- If `sendMail` succeeds, log the success message including the `messageId` from the result. Return `true`.
- If `sendMail` fails (throws error), log the error using the logger. Return `false`.
- **Acceptance Criteria (ACs):**
- AC1: `nodemailer` and `@types/nodemailer` dependencies are added.
- AC2: `EMAIL_*` variables are defined in `.env.example` and loaded from config.
- AC3: `emailSender.ts` module exists and exports `sendDigestEmail`.
- AC4: `sendDigestEmail` correctly creates a Nodemailer transporter using configuration from `.env`. Transporter verification is attempted (optional AC).
- AC5: The `to` field is correctly populated based on `EMAIL_RECIPIENTS`.
- AC6: `transporter.sendMail` is called with correct `from`, `to`, `subject`, and `html` options.
- AC7: Email sending success (including message ID) or failure is logged clearly.
- AC8: The function returns `true` on successful sending, `false` otherwise.
---
### Story 5.4: Integrate Email Assembly and Sending into Main Workflow
- **User Story / Goal:** As a developer, I want the main application workflow (`src/index.ts`) to orchestrate the final steps: assembling digest data, rendering the HTML, and triggering the email send after all previous stages are complete.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`.
- Execute these steps *after* the main loop (where stories are fetched, scraped, summarized, and persisted) completes:
- Log "Starting final digest assembly and email dispatch...".
- Determine the path to the current date-stamped output directory.
- Call `const digestData = await assembleDigestData(dateDirPath)`.
- Check if `digestData` array is not empty.
- If yes:
- Get the current date string (e.g., 'YYYY-MM-DD').
- `const htmlContent = renderDigestHtml(digestData, currentDate)`.
- `const subject = \`BMad Hacker Daily Digest - ${currentDate}\``.
- `const emailSent = await sendDigestEmail(subject, htmlContent)`.
- Log the final outcome based on `emailSent` ("Digest email sent successfully." or "Failed to send digest email.").
- If no (`digestData` is empty or assembly failed):
- Log an error: "Failed to assemble digest data or no data found. Skipping email."
- Log "BMad Hacker Daily Digest process finished."
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes all stages (Epics 1-4) and then proceeds to email assembly and sending.
- AC2: `assembleDigestData` is called correctly with the output directory path after other processing is done.
- AC3: If data is assembled, `renderDigestHtml` and `sendDigestEmail` are called with the correct data, subject, and HTML.
- AC4: The final success or failure of the email sending step is logged.
- AC5: If `assembleDigestData` returns no data, email sending is skipped, and an appropriate message is logged.
- AC6: The application logs a final completion message.
---
### Story 5.5: Implement Stage Testing Utility for Emailing
- **User Story / Goal:** As a developer, I want a separate script/command to test the email assembly, rendering, and sending logic using persisted local data, including a crucial `--dry-run` option to prevent accidental email sending during tests.
- **Detailed Requirements:**
- Add `yargs` dependency for argument parsing: `npm install yargs @types/yargs --save-dev`.
- Create a new standalone script file: `src/stages/send_digest.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`, `yargs`.
- Use `yargs` to parse command-line arguments, specifically looking for a `--dry-run` boolean flag (defaulting to `false`). Allow an optional argument for specifying the date-stamped directory, otherwise default to current date.
- The script should:
- Initialize logger, load config.
- Determine the target date-stamped directory path (from arg or default). Log the target directory.
- Call `await assembleDigestData(dateDirPath)`.
- If data is assembled and not empty:
- Determine the date string for the subject/title.
- Call `renderDigestHtml(digestData, dateString)` to get HTML.
- Construct the subject string.
- Check the `dryRun` flag:
- If `true`: Log "DRY RUN enabled. Skipping actual email send.". Log the subject. Save the `htmlContent` to a file in the target directory (e.g., `_digest_preview.html`). Log that the preview file was saved.
- If `false`: Log "Live run: Attempting to send email...". Call `await sendDigestEmail(subject, htmlContent)`. Log success/failure based on the return value.
- If data assembly fails or is empty, log the error.
- Add script to `package.json`: `"stage:email": "ts-node src/stages/send_digest.ts --"`. The `--` allows passing arguments like `--dry-run`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/send_digest.ts` exists. `yargs` dependency is added.
- AC2: The script `stage:email` is defined in `package.json` allowing arguments.
- AC3: Running `npm run stage:email -- --dry-run` reads local data, renders HTML, logs the intent, saves `_digest_preview.html` locally, and does *not* call `sendDigestEmail`.
- AC4: Running `npm run stage:email` (without `--dry-run`) reads local data, renders HTML, and *does* call `sendDigestEmail`, logging the outcome.
- AC5: The script correctly identifies and acts upon the `--dry-run` flag.
- AC6: Logs clearly distinguish between dry runs and live runs and report success/failure.
- AC7: The script operates using only local files and the email configuration/service; it does not invoke prior pipeline stages (Algolia, scraping, Ollama).

- Add required configuration variables to `.env.example` (and local `.env`): `EMAIL_HOST`, `EMAIL_PORT` (e.g., 587), `EMAIL_SECURE` (e.g., `false` for STARTTLS on 587, `true` for 465), `EMAIL_USER`, `EMAIL_PASS`, `EMAIL_FROM` (e.g., `"Your Name <you@example.com>"`), `EMAIL_RECIPIENTS` (comma-separated list).
- Create a new module: `src/email/emailSender.ts`.
- Implement an async function `sendDigestEmail(subject: string, htmlContent: string): Promise<boolean>`.
- Inside the function:
- Load the `EMAIL_*` variables from the config module.
- Create a Nodemailer transporter using `nodemailer.createTransport` with the loaded config (host, port, secure flag, auth: { user, pass }).
- Verify transporter configuration using `transporter.verify()` (optional but recommended). Log verification success/failure.
- Parse the `EMAIL_RECIPIENTS` string into an array or comma-separated string suitable for the `to` field.
- Define the `mailOptions`: `{ from: EMAIL_FROM, to: parsedRecipients, subject: subject, html: htmlContent }`.
- Call `await transporter.sendMail(mailOptions)`.
- If `sendMail` succeeds, log the success message including the `messageId` from the result. Return `true`.
- If `sendMail` fails (throws error), log the error using the logger. Return `false`.
- **Acceptance Criteria (ACs):**
- AC1: `nodemailer` and `@types/nodemailer` dependencies are added.
- AC2: `EMAIL_*` variables are defined in `.env.example` and loaded from config.
- AC3: `emailSender.ts` module exists and exports `sendDigestEmail`.
- AC4: `sendDigestEmail` correctly creates a Nodemailer transporter using configuration from `.env`. Transporter verification is attempted (optional AC).
- AC5: The `to` field is correctly populated based on `EMAIL_RECIPIENTS`.
- AC6: `transporter.sendMail` is called with correct `from`, `to`, `subject`, and `html` options.
- AC7: Email sending success (including message ID) or failure is logged clearly.
- AC8: The function returns `true` on successful sending, `false` otherwise.

### Story 5.4: Integrate Email Assembly and Sending into Main Workflow
- **User Story / Goal:** As a developer, I want the main application workflow (`src/index.ts`) to orchestrate the final steps: assembling digest data, rendering the HTML, and triggering the email send after all previous stages are complete.
- **Detailed Requirements:**
- Modify the main execution flow in `src/index.ts`.
- Import `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`.
- Execute these steps *after* the main loop (where stories are fetched, scraped, summarized, and persisted) completes:
- Log "Starting final digest assembly and email dispatch...".
- Determine the path to the current date-stamped output directory.
- Call `const digestData = await assembleDigestData(dateDirPath)`.
- Check if `digestData` array is not empty.
- If yes:
- Get the current date string (e.g., 'YYYY-MM-DD').
- `const htmlContent = renderDigestHtml(digestData, currentDate)`.
- `const subject = \`BMad Hacker Daily Digest - ${currentDate}\``.
- `const emailSent = await sendDigestEmail(subject, htmlContent)`.
- Log the final outcome based on `emailSent` ("Digest email sent successfully." or "Failed to send digest email.").
- If no (`digestData` is empty or assembly failed):
- Log an error: "Failed to assemble digest data or no data found. Skipping email."
- Log "BMad Hacker Daily Digest process finished."
- **Acceptance Criteria (ACs):**
- AC1: Running `npm run dev` executes all stages (Epics 1-4) and then proceeds to email assembly and sending.
- AC2: `assembleDigestData` is called correctly with the output directory path after other processing is done.
- AC3: If data is assembled, `renderDigestHtml` and `sendDigestEmail` are called with the correct data, subject, and HTML.
- AC4: The final success or failure of the email sending step is logged.
- AC5: If `assembleDigestData` returns no data, email sending is skipped, and an appropriate message is logged.
- AC6: The application logs a final completion message.
---
### Story 5.5: Implement Stage Testing Utility for Emailing
- **User Story / Goal:** As a developer, I want a separate script/command to test the email assembly, rendering, and sending logic using persisted local data, including a crucial `--dry-run` option to prevent accidental email sending during tests.
- **Detailed Requirements:**
- Add `yargs` dependency for argument parsing: `npm install yargs @types/yargs --save-dev`.
- Create a new standalone script file: `src/stages/send_digest.ts`.
- Import necessary modules: `fs`, `path`, `logger`, `config`, `assembleDigestData`, `renderDigestHtml`, `sendDigestEmail`, `yargs`.
- Use `yargs` to parse command-line arguments, specifically looking for a `--dry-run` boolean flag (defaulting to `false`). Allow an optional argument for specifying the date-stamped directory, otherwise default to current date.
- The script should:
- Initialize logger, load config.
- Determine the target date-stamped directory path (from arg or default). Log the target directory.
- Call `await assembleDigestData(dateDirPath)`.
- If data is assembled and not empty:
- Determine the date string for the subject/title.
- Call `renderDigestHtml(digestData, dateString)` to get HTML.
- Construct the subject string.
- Check the `dryRun` flag:
- If `true`: Log "DRY RUN enabled. Skipping actual email send.". Log the subject. Save the `htmlContent` to a file in the target directory (e.g., `_digest_preview.html`). Log that the preview file was saved.
- If `false`: Log "Live run: Attempting to send email...". Call `await sendDigestEmail(subject, htmlContent)`. Log success/failure based on the return value.
- If data assembly fails or is empty, log the error.
- Add script to `package.json`: `"stage:email": "ts-node src/stages/send_digest.ts --"`. The `--` allows passing arguments like `--dry-run`.
- **Acceptance Criteria (ACs):**
- AC1: The file `src/stages/send_digest.ts` exists. `yargs` dependency is added.
- AC2: The script `stage:email` is defined in `package.json` allowing arguments.
- AC3: Running `npm run stage:email -- --dry-run` reads local data, renders HTML, logs the intent, saves `_digest_preview.html` locally, and does *not* call `sendDigestEmail`.
- AC4: Running `npm run stage:email` (without `--dry-run`) reads local data, renders HTML, and *does* call `sendDigestEmail`, logging the outcome.
- AC5: The script correctly identifies and acts upon the `--dry-run` flag.
- AC6: Logs clearly distinguish between dry runs and live runs and report success/failure.
- AC7: The script operates using only local files and the email configuration/service; it does not invoke prior pipeline stages (Algolia, scraping, Ollama).

# Project Brief: BMad Hacker Daily Digest
## Introduction / Problem Statement
Hacker News (HN) comment threads contain valuable insights but can be prohibitively long to read thoroughly. The BMad Hacker Daily Digest project aims to solve this by providing a time-efficient way to stay informed about the collective intelligence within HN discussions. The service will automatically fetch the top 10 HN stories daily, retrieve a manageable subset of their comments using the Algolia HN API, generate concise summaries of both the linked article (when possible) and the comment discussion using an LLM, and deliver these summaries in a daily email briefing. This project also serves as a practical learning exercise focused on agent-driven development, TypeScript, Node.js backend services, API integration, and local LLM usage with Ollama.
## Vision & Goals
- **Vision:** To provide a quick, reliable, and automated way for users to stay informed about the key insights and discussions happening within the Hacker News community without needing to read lengthy comment threads.
- **Primary Goals (MVP - SMART):**
- **Fetch HN Story Data:** Successfully retrieve the IDs and metadata (title, URL, HN link) of the top 10 Hacker News stories using the Algolia HN Search API when triggered.
- **Retrieve Limited Comments:** For each fetched story, retrieve a predefined, limited set of associated comments using the Algolia HN Search API.
- **Attempt Article Scraping:** For each story's external URL, attempt to fetch the raw HTML and extract the main article text using basic methods (Node.js native fetch, article-extractor/Cheerio), handling failures gracefully.
- **Generate Summaries (LLM):** Using a local LLM (via Ollama, configured endpoint), generate: an "Article Summary" from scraped text (if successful), and a separate "Discussion Summary" from fetched comments.
- **Assemble & Send Digest (Manual Trigger):** Format results for 10 stories into a single HTML email and successfully send it to recipients (list defined in config) using Nodemailer when manually triggered via CLI.
- **Success Metrics (Initial Ideas for MVP):**
- **Successful Execution:** The entire process completes successfully without crashing when manually triggered via CLI for 3 different test runs.
- **Digest Content:** The generated email contains results for 10 stories (correct links, discussion summary, article summary where possible). Spot checks confirm relevance.
- **Error Handling:** Scraping failures are logged, and the process continues using only comment summaries for affected stories without halting the script.
## Target Audience / Users
**Primary User (MVP):** The developer undertaking this project. The primary motivation is learning and demonstrating agent-driven development, TypeScript, Node.js (v22), API integration (Algolia, LLM, Email), local LLMs (Ollama), and configuration management ( .env ). The key need is an interesting, achievable project scope utilizing these technologies.
**Secondary User (Potential):** Time-constrained HN readers/tech enthusiasts needing automated discussion summaries. Addressing their needs fully is outside MVP scope but informs potential future direction.
## Key Features / Scope (High-Level Ideas for MVP)
- Fetch Top HN Stories (Algolia API).
- Fetch Limited Comments (Algolia API).
- Local File Storage (Date-stamped folder, structured text/JSON files).
- Attempt Basic Article Scraping (Node.js v22 native fetch, basic extraction).
- Handle Scraping Failures (Log error, proceed with comment-only summary).
- Generate Summaries (Local Ollama via configured endpoint: Article Summary if scraped, Discussion Summary always).
- Format Digest Email (HTML: Article Summary (opt.), Discussion Summary, HN link, Article link).
- Manual Email Dispatch (Nodemailer, credentials from .env , recipient list from .env ).
- CLI Trigger (Manual command to run full process).
**Explicitly OUT of Scope for MVP:** Advanced scraping (JS render, anti-bot), processing _all_ comments/MapReduce summaries, automated scheduling (cron), database integration, cloud deployment/web frontend, user management (sign-ups etc.), production-grade error handling/monitoring/deliverability, fine-tuning LLM prompts, sophisticated retry logic.
## Known Technical Constraints or Preferences
- **Constraints/Preferences:**
- **Language/Runtime:** TypeScript running on Node.js v22.
- **Execution Environment:** Local machine execution for MVP.
- **Trigger Mechanism:** Manual CLI trigger only for MVP.
- **Configuration Management:** Use a `.env` file for configuration: LLM endpoint URL, email credentials, recipient email list, potentially comment fetch limits etc.
- **HTTP Requests:** Use Node.js v22 native fetch API (no Axios).
- **HN Data Source:** Algolia HN Search API.
- **Web Scraping:** Basic, best-effort only (native fetch + static HTML extraction). Must handle failures gracefully.
- **LLM Integration:** Local Ollama via configurable endpoint for MVP. Design for potential swap to cloud LLMs. Functionality over quality for MVP.
- **Summarization Strategy:** Separate Article/Discussion summaries. Limit comments processed per story (configurable). No MapReduce.
- **Data Storage:** Local file system (structured text/JSON in date-stamped folders). No database.
- **Email Delivery:** Nodemailer. Read credentials and recipient list from `.env`. Basic setup, no production deliverability focus.
- **Primary Goal Context:** Focus on functional pipeline for learning/demonstration.
- **Risks:**
- Algolia HN API Issues: Changes, rate limits, availability.
- Web Scraping Fragility: High likelihood of failure limiting Article Summaries.
- LLM Variability & Quality: Inconsistent performance/quality from local Ollama; potential errors.
*Incomplete Discussion Capture: Limited comment fetching may miss key insights.
*Email Configuration/Deliverability: Fragility of personal credentials; potential spam filtering.
*Manual Trigger Dependency: Digest only generated on manual execution.
*Configuration Errors: Incorrect `.env` settings could break the application.
_(User Note: Risks acknowledged and accepted given the project's learning goals.)_
## Relevant Research (Optional)
Feasibility: Core concept confirmed technically feasible with available APIs/libraries.
Existing Tools & Market Context: Similar tools exist (validating interest), but daily email format appears distinct.
API Selection: Algolia HN Search API chosen for filtering/sorting capabilities.
Identified Technical Challenges: Confirmed complexities of scraping and handling large comment volumes within LLM limits, informing MVP scope.
Local LLM Viability: Ollama confirmed as viable for local MVP development/testing, with potential for future swapping.
## PM Prompt
**PM Agent Handoff Prompt: BMad Hacker Daily Digest**
**Summary of Key Insights:**
This Project Brief outlines the "BMad Hacker Daily Digest," a command-line tool designed to provide daily email summaries of discussions from top Hacker News (HN) comment threads. The core problem is the time required to read lengthy but valuable HN discussions. The MVP aims to fetch the top 10 HN stories, retrieve a limited set of comments via the Algolia HN API, attempt basic scraping of linked articles (with fallback), generate separate summaries for articles (if scraped) and comments using a local LLM (Ollama), and email the digest to the developer using Nodemailer. This project primarily serves as a learning exercise and demonstration of agent-driven development in TypeScript.
**Areas Requiring Special Attention (for PRD):**
- **Comment Selection Logic:** Define the specific criteria for selecting the "limited set" of comments from Algolia (e.g., number of comments, recency, token count limit).
- **Basic Scraping Implementation:** Detail the exact steps for the basic article scraping attempt (libraries like Node.js native fetch, article-extractor/Cheerio), including specific error handling and the fallback mechanism.
- **LLM Prompting:** Define the precise prompts for generating the "Article Summary" and the "Discussion Summary" separately.
- **Email Formatting:** Specify the exact structure, layout, and content presentation within the daily HTML email digest.
- **CLI Interface:** Define the specific command(s), arguments, and expected output/feedback for the manual trigger.
- **Local File Structure:** Define the structure for storing intermediate data and logs in local text files within date-stamped folders.
**Development Context:**
This brief was developed through iterative discussion, starting from general app ideas and refining scope based on user interest (HN discussions) and technical feasibility for a learning/demo project. Key decisions include prioritizing comment summarization, using the Algolia HN API, starting with local execution (Ollama, Nodemailer), and including only a basic, best-effort scraping attempt in the MVP.
**Guidance on PRD Detail:**
- Focus detailed requirements and user stories on the core data pipeline: HN API Fetch -> Comment Selection -> Basic Scrape Attempt -> LLM Summarization (x2) -> Email Formatting/Sending -> CLI Trigger.
- Keep potential post-MVP enhancements (cloud deployment, frontend, database, advanced scraping, scheduling) as high-level future considerations.
- Technical implementation details for API/LLM interaction should allow flexibility for potential future swapping (e.g., Ollama to cloud LLM).
**User Preferences:**
- Execution: Manual CLI trigger for MVP.
- Data Storage: Local text files for MVP.
- LLM: Ollama for local development/MVP. Ability to potentially switch to cloud API later.
- Summaries: Generate separate summaries for article (if available) and comments.
- API: Use Algolia HN Search API.
- Email: Use Nodemailer for self-send in MVP.
- Tech Stack: TypeScript, Node.js v22.

# BMad Hacker Daily Digest Product Requirements Document (PRD)
## Intro
The BMad Hacker Daily Digest is a command-line tool designed to address the time-consuming nature of reading extensive Hacker News (HN) comment threads. It aims to provide users with a time-efficient way to grasp the collective intelligence and key insights from discussions on top HN stories. The service will fetch the top 10 HN stories daily, retrieve a configurable number of comments for each, attempt to scrape the linked article, generate separate summaries for the article (if scraped) and the comment discussion using a local LLM, and deliver these summaries in a single daily email briefing triggered manually. This project also serves as a practical learning exercise in agent-driven development, TypeScript, Node.js, API integration, and local LLM usage, starting from the provided "bmad-boilerplate" template.
## Goals and Context
- **Project Objectives:**
- Provide a quick, reliable, automated way to stay informed about key HN discussions without reading full threads.
- Successfully fetch top 10 HN story metadata via Algolia HN API.
- Retrieve a _configurable_ number of comments per story (default 50) via Algolia HN API.
- Attempt basic scraping of linked article content, handling failures gracefully.
- Generate distinct Article Summaries (if scraped) and Discussion Summaries using a local LLM (Ollama).
- Assemble summaries for 10 stories into an HTML email and send via Nodemailer upon manual CLI trigger.
- Serve as a learning platform for agent-driven development, TypeScript, Node.js v22, API integration, local LLMs, and configuration management, leveraging the "bmad-boilerplate" structure and tooling.
- **Measurable Outcomes:**
- The tool completes its full process (fetch, scrape attempt, summarize, email) without crashing on manual CLI trigger across multiple test runs.
- The generated email digest consistently contains results for 10 stories, including correct links, discussion summaries, and article summaries where scraping was successful.
- Errors during article scraping are logged, and the process continues for affected stories using only comment summaries, without halting the script.
- **Success Criteria:**
- Successful execution of the end-to-end process via CLI trigger for 3 consecutive test runs.
- Generated email is successfully sent and received, containing summaries for all 10 fetched stories (article summary optional based on scraping success).
- Scraping failures are logged appropriately without stopping the overall process.
- **Key Performance Indicators (KPIs):**
- Successful Runs / Total Runs (Target: 100% for MVP tests)
- Stories with Article Summaries / Total Stories (Measures scraping effectiveness)
- Stories with Discussion Summaries / Total Stories (Target: 100%)
* Manual Qualitative Check: Relevance and coherence of summaries in the digest.
## Scope and Requirements (MVP / Current Version)
### Functional Requirements (High-Level)
- **HN Story Fetching:** Retrieve IDs and metadata (title, URL, HN link) for the top 10 stories from Algolia HN Search API.
- **HN Comment Fetching:** For each story, retrieve comments from Algolia HN Search API up to a maximum count defined in a `.env` configuration variable (`MAX_COMMENTS_PER_STORY`, default 50).
- **Article Content Scraping:** Attempt to fetch HTML and extract main text content from the story's external URL using basic methods (e.g., Node.js native fetch, optionally `article-extractor` or similar basic library).
- **Scraping Failure Handling:** If scraping fails, log the error and proceed with generating only the Discussion Summary for that story.
- **LLM Summarization:**
- Generate an "Article Summary" from scraped text (if successful) using a configured local LLM (Ollama endpoint).
- Generate a "Discussion Summary" from the fetched comments using the same LLM.
- Initial Prompts (Placeholders - refine in Epics):
- _Article Prompt:_ "Summarize the key points of the following article text: {Article Text}"
- _Discussion Prompt:_ "Summarize the main themes, viewpoints, and key insights from the following Hacker News comments: {Comment Texts}"
- **Digest Formatting:** Combine results for the 10 stories into a single HTML email. Each story entry should include: Story Title, HN Link, Article Link, Article Summary (if available), Discussion Summary.
- **Email Dispatch:** Send the formatted HTML email using Nodemailer to a recipient list defined in `.env`. Use credentials also stored in `.env`.
- **Main Execution Trigger:** Initiate the _entire implemented pipeline_ via a manual command-line interface (CLI) trigger, using the standard scripts defined in the boilerplate (`npm run dev`, `npm start` after build). Each functional epic should add its capability to this main execution flow.
- **Configuration:** Manage external parameters (Algolia API details (if needed), LLM endpoint URL, `MAX_COMMENTS_PER_STORY`, Nodemailer credentials, recipient email list, output directory path) via a `.env` file, based on the provided `.env.example`.
- **Incremental Logging & Data Persistence:**
- Implement basic console logging for key steps and errors throughout the pipeline.
- Persist intermediate data artifacts (fetched stories/comments, scraped text, generated summaries) to local files within a configurable, date-stamped directory structure (e.g., `./output/YYYY-MM-DD/`).
- This persistence should be implemented incrementally within the relevant functional epics (Data Acquisition, Scraping, Summarization).
- **Stage Testing Utilities:**
- Provide separate utility scripts or CLI commands to allow testing individual pipeline stages in isolation (e.g., fetching HN data, scraping URLs, summarizing text, sending email).
- These utilities should support using locally saved files as input (e.g., test scraping using a file containing story URLs, test summarization using a file containing text). This facilitates development and debugging.
### Non-Functional Requirements (NFRs)
- **Performance:** MVP focuses on functionality over speed. Should complete within a reasonable time (e.g., < 5 minutes) on a typical developer machine for local LLM use. No specific response time targets.
- **Scalability:** Designed for single-user, local execution. No scaling requirements for MVP.
- **Reliability/Availability:**
- The script must handle article scraping failures gracefully (log and continue).
- Basic error handling for API calls (e.g., log network errors).
- Local LLM interaction may fail; basic error logging is sufficient for MVP.
- No requirement for automated retries or production-grade error handling.
- **Security:**
- Email credentials must be stored securely via `.env` file and not committed to version control (as per boilerplate `.gitignore`).
- No other specific security requirements for local MVP.
- **Maintainability:**
- Code should be well-structured TypeScript.
- Adherence to the linting (ESLint) and formatting (Prettier) rules configured in the "bmad-boilerplate" is required. Use `npm run lint` and `npm run format`.
- Modularity is desired to potentially swap LLM providers later and facilitate stage testing.
- **Usability/Accessibility:** N/A (CLI tool for developer).
- **Other Constraints:**
- Must use TypeScript and Node.js v22.
- Must run locally on the developer's machine.
- Must use Node.js v22 native `Workspace` API for HTTP requests.
- Must use Algolia HN Search API for HN data.
- Must use a local Ollama instance via a configurable HTTP endpoint.
- Must use Nodemailer for email dispatch.
- Must use `.env` for configuration based on `.env.example`.
- Must use local file system for logging and intermediate data storage. Ensure output/log directories are gitignored.
- Focus on a functional pipeline for learning/demonstration.
### User Experience (UX) Requirements (High-Level)
- The primary UX goal is to deliver a time-saving digest.
- For the developer user, the main CLI interaction should be simple: using standard boilerplate scripts like `npm run dev` or `npm start` to trigger the full process.
- Feedback during CLI execution (e.g., "Fetching stories...", "Summarizing story X/10...", "Sending email...") is desirable via console logging.
- Separate CLI commands/scripts for testing individual stages should provide clear input/output mechanisms.
### Integration Requirements (High-Level)
- **Algolia HN Search API:** Fetching top stories and comments. Requires understanding API structure and query parameters.
- **Ollama Service:** Sending text (article content, comments) and receiving summaries via its API endpoint. Endpoint URL must be configurable.
- **SMTP Service (via Nodemailer):** Sending the final digest email. Requires valid SMTP credentials and recipient list configured in `.env`.
### Testing Requirements (High-Level)
- MVP success relies on manual end-to-end test runs confirming successful execution and valid email output.
- Unit/integration tests are encouraged using the **Jest framework configured in the boilerplate**. Focus testing effort on the core pipeline components. Use `npm run test`.

## Initial Architect Prompt
### Technical Infrastructure
- **Starter Project/Template:** **Mandatory: Use the provided "bmad-boilerplate".** This includes TypeScript setup, Node.js v22 compatibility, Jest, ESLint, Prettier, `ts-node`, `.env` handling via `.env.example`, and standard scripts (`dev`, `build`, `test`, `lint`, `format`).
- **Hosting/Cloud Provider:** Local machine execution only for MVP. No cloud deployment.
- **Frontend Platform:** N/A (CLI tool).
- **Backend Platform:** Node.js v22 with TypeScript (as provided by the boilerplate). No specific Node.js framework mandated, but structure should support modularity and align with boilerplate setup.
- **Database Requirements:** None. Local file system for intermediate data storage and logging only. Structure TBD (e.g., `./output/YYYY-MM-DD/`). Ensure output directory is configurable via `.env` and gitignored.
### Technical Constraints
- Must adhere to the structure and tooling provided by "bmad-boilerplate".
- Must use Node.js v22 native `Workspace` for HTTP requests.
- Must use the Algolia HN Search API for fetching HN data.
- Must integrate with a local Ollama instance via a configurable HTTP endpoint. Design should allow potential swapping to other LLM APIs later.
- Must use Nodemailer for sending email.
- Configuration (LLM endpoint, email credentials, recipients, `MAX_COMMENTS_PER_STORY`, output dir path) must be managed via a `.env` file based on `.env.example`.
- Article scraping must be basic, best-effort, and handle failures gracefully without stopping the main process.
- Intermediate data must be persisted locally incrementally.
- Code must adhere to the ESLint and Prettier configurations within the boilerplate.
### Deployment Considerations
- Execution is manual via CLI trigger only, using `npm run dev` or `npm start`.
- No CI/CD required for MVP.
- Single environment: local development machine.
### Local Development & Testing Requirements
- The entire application runs locally.
- The main CLI command (`npm run dev`/`start`) should execute the _full implemented pipeline_.
- **Separate utility scripts/commands MUST be provided** for testing individual pipeline stages (fetch, scrape, summarize, email) potentially using local file I/O. Architecture should facilitate creating these stage runners. (e.g., `npm run stage:fetch`, `npm run stage:scrape -- --inputFile <path>`, `npm run stage:summarize -- --inputFile <path>`, `npm run stage:email -- --inputFile <path> [--dry-run]`).
- The boilerplate provides `npm run test` using Jest for running automated unit/integration tests.
- The boilerplate provides `npm run lint` and `npm run format` for code quality checks.
- Basic console logging is required. File logging can be considered by the architect.
- Testability of individual modules (API clients, scraper, summarizer, emailer) is crucial and should leverage the Jest setup and stage testing utilities.
### Other Technical Considerations
- **Modularity:** Design components (HN client, scraper, LLM client, emailer) with clear interfaces to facilitate potential future modifications (e.g., changing LLM provider) and independent stage testing.
- **Error Handling:** Focus on robust handling of scraping failures and basic handling of API/network errors. Implement within the boilerplate structure. Logging should clearly indicate errors.
- **Resource Management:** Be mindful of local resources when interacting with the LLM, although optimization is not a primary MVP goal.
- **Dependency Management:** Add necessary production dependencies (e.g., `nodemailer`, potentially `article-extractor`, libraries for date handling or file system operations if needed) to the boilerplate's `package.json`. Keep dependencies minimal.
- **Configuration Loading:** Implement a robust way to load and validate settings from the `.env` file early in the application startup.

# BMad Hacker Daily Digest Product Requirements Document (PRD)
## Intro
The BMad Hacker Daily Digest is a command-line tool designed to address the time-consuming nature of reading extensive Hacker News (HN) comment threads. It aims to provide users with a time-efficient way to grasp the collective intelligence and key insights from discussions on top HN stories. The service will fetch the top 10 HN stories daily, retrieve a configurable number of comments for each, attempt to scrape the linked article, generate separate summaries for the article (if scraped) and the comment discussion using a local LLM, and deliver these summaries in a single daily email briefing triggered manually. This project also serves as a practical learning exercise in agent-driven development, TypeScript, Node.js, API integration, and local LLM usage, starting from the provided "bmad-boilerplate" template.
## Goals and Context
- **Project Objectives:**
- Provide a quick, reliable, automated way to stay informed about key HN discussions without reading full threads.
- Successfully fetch top 10 HN story metadata via Algolia HN API.
- Retrieve a _configurable_ number of comments per story (default 50) via Algolia HN API.
- Attempt basic scraping of linked article content, handling failures gracefully.
- Generate distinct Article Summaries (if scraped) and Discussion Summaries using a local LLM (Ollama).
- Assemble summaries for 10 stories into an HTML email and send via Nodemailer upon manual CLI trigger.
- Serve as a learning platform for agent-driven development, TypeScript, Node.js v22, API integration, local LLMs, and configuration management, leveraging the "bmad-boilerplate" structure and tooling.
- **Measurable Outcomes:**
- The tool completes its full process (fetch, scrape attempt, summarize, email) without crashing on manual CLI trigger across multiple test runs.
- The generated email digest consistently contains results for 10 stories, including correct links, discussion summaries, and article summaries where scraping was successful.
- Errors during article scraping are logged, and the process continues for affected stories using only comment summaries, without halting the script.
- **Success Criteria:**
- Successful execution of the end-to-end process via CLI trigger for 3 consecutive test runs.
- Generated email is successfully sent and received, containing summaries for all 10 fetched stories (article summary optional based on scraping success).
- Scraping failures are logged appropriately without stopping the overall process.
- **Key Performance Indicators (KPIs):**
- Successful Runs / Total Runs (Target: 100% for MVP tests)
- Stories with Article Summaries / Total Stories (Measures scraping effectiveness)
- Stories with Discussion Summaries / Total Stories (Target: 100%)
* Manual Qualitative Check: Relevance and coherence of summaries in the digest.
## Scope and Requirements (MVP / Current Version)
### Functional Requirements (High-Level)
- **HN Story Fetching:** Retrieve IDs and metadata (title, URL, HN link) for the top 10 stories from Algolia HN Search API.
- **HN Comment Fetching:** For each story, retrieve comments from Algolia HN Search API up to a maximum count defined in a `.env` configuration variable (`MAX_COMMENTS_PER_STORY`, default 50).
- **Article Content Scraping:** Attempt to fetch HTML and extract main text content from the story's external URL using basic methods (e.g., Node.js native fetch, optionally `article-extractor` or similar basic library).
- **Scraping Failure Handling:** If scraping fails, log the error and proceed with generating only the Discussion Summary for that story.
- **LLM Summarization:**
- Generate an "Article Summary" from scraped text (if successful) using a configured local LLM (Ollama endpoint).
- Generate a "Discussion Summary" from the fetched comments using the same LLM.
- Initial Prompts (Placeholders - refine in Epics):
- _Article Prompt:_ "Summarize the key points of the following article text: {Article Text}"
- _Discussion Prompt:_ "Summarize the main themes, viewpoints, and key insights from the following Hacker News comments: {Comment Texts}"
- **Digest Formatting:** Combine results for the 10 stories into a single HTML email. Each story entry should include: Story Title, HN Link, Article Link, Article Summary (if available), Discussion Summary.
- **Email Dispatch:** Send the formatted HTML email using Nodemailer to a recipient list defined in `.env`. Use credentials also stored in `.env`.
- **Main Execution Trigger:** Initiate the _entire implemented pipeline_ via a manual command-line interface (CLI) trigger, using the standard scripts defined in the boilerplate (`npm run dev`, `npm start` after build). Each functional epic should add its capability to this main execution flow.
- **Configuration:** Manage external parameters (Algolia API details (if needed), LLM endpoint URL, `MAX_COMMENTS_PER_STORY`, Nodemailer credentials, recipient email list, output directory path) via a `.env` file, based on the provided `.env.example`.
- **Incremental Logging & Data Persistence:**
- Implement basic console logging for key steps and errors throughout the pipeline.
- Persist intermediate data artifacts (fetched stories/comments, scraped text, generated summaries) to local files within a configurable, date-stamped directory structure (e.g., `./output/YYYY-MM-DD/`).
- This persistence should be implemented incrementally within the relevant functional epics (Data Acquisition, Scraping, Summarization).
- **Stage Testing Utilities:**
- Provide separate utility scripts or CLI commands to allow testing individual pipeline stages in isolation (e.g., fetching HN data, scraping URLs, summarizing text, sending email).
- These utilities should support using locally saved files as input (e.g., test scraping using a file containing story URLs, test summarization using a file containing text). This facilitates development and debugging.
### Non-Functional Requirements (NFRs)
- **Performance:** MVP focuses on functionality over speed. Should complete within a reasonable time (e.g., < 5 minutes) on a typical developer machine for local LLM use. No specific response time targets.
- **Scalability:** Designed for single-user, local execution. No scaling requirements for MVP.
- **Reliability/Availability:**
- The script must handle article scraping failures gracefully (log and continue).
- Basic error handling for API calls (e.g., log network errors).
- Local LLM interaction may fail; basic error logging is sufficient for MVP.
- No requirement for automated retries or production-grade error handling.
- **Security:**
- Email credentials must be stored securely via `.env` file and not committed to version control (as per boilerplate `.gitignore`).
- No other specific security requirements for local MVP.
- **Maintainability:**
- Code should be well-structured TypeScript.
- Adherence to the linting (ESLint) and formatting (Prettier) rules configured in the "bmad-boilerplate" is required. Use `npm run lint` and `npm run format`.
- Modularity is desired to potentially swap LLM providers later and facilitate stage testing.
- **Usability/Accessibility:** N/A (CLI tool for developer).
- **Other Constraints:**
- Must use TypeScript and Node.js v22.
- Must run locally on the developer's machine.
- Must use Node.js v22 native `Workspace` API for HTTP requests.
- Must use Algolia HN Search API for HN data.
- Must use a local Ollama instance via a configurable HTTP endpoint.
- Must use Nodemailer for email dispatch.
- Must use `.env` for configuration based on `.env.example`.
- Must use local file system for logging and intermediate data storage. Ensure output/log directories are gitignored.
- Focus on a functional pipeline for learning/demonstration.
### User Experience (UX) Requirements (High-Level)
- The primary UX goal is to deliver a time-saving digest.
- For the developer user, the main CLI interaction should be simple: using standard boilerplate scripts like `npm run dev` or `npm start` to trigger the full process.
- Feedback during CLI execution (e.g., "Fetching stories...", "Summarizing story X/10...", "Sending email...") is desirable via console logging.
- Separate CLI commands/scripts for testing individual stages should provide clear input/output mechanisms.
### Integration Requirements (High-Level)
- **Algolia HN Search API:** Fetching top stories and comments. Requires understanding API structure and query parameters.
- **Ollama Service:** Sending text (article content, comments) and receiving summaries via its API endpoint. Endpoint URL must be configurable.
- **SMTP Service (via Nodemailer):** Sending the final digest email. Requires valid SMTP credentials and recipient list configured in `.env`.
### Testing Requirements (High-Level)
- MVP success relies on manual end-to-end test runs confirming successful execution and valid email output.
- Unit/integration tests are encouraged using the **Jest framework configured in the boilerplate**. Focus testing effort on the core pipeline components. Use `npm run test`.
- **Stage-specific testing utilities (as defined in Functional Requirements) are required** to support development and verification of individual pipeline components.

- `src/`: Main application source code.
- `clients/`: Modules dedicated to interacting with specific external APIs (Algolia, Ollama).
- `core/`: Orchestrates the main application pipeline steps.
- `email/`: Handles all aspects of creating and sending the final email digest.
- `scraper/`: Contains the logic for fetching and extracting article content.
- `stages/`: Holds the independent, runnable scripts for testing each major pipeline stage.
- `types/`: Central location for shared TypeScript interfaces and type definitions.
- `utils/`: Reusable utility functions (config loading, logging, date formatting) that don't belong to a specific feature domain.

## Notes
- This structure promotes modularity by separating concerns (clients, scraping, email, core logic, stages, utils).
- Clear separation into directories like `clients`, `scraper`, `email`, and `stages` aids independent development, testing, and potential AI agent implementation tasks targeting specific functionalities.
- Stage runner scripts in `src/stages/` directly address the PRD requirement for testing pipeline phases independently .

## Notes
- This structure promotes modularity by separating concerns (clients, scraping, email, core logic, stages, utils).
- Clear separation into directories like `clients`, `scraper`, `email`, and `stages` aids independent development, testing, and potential AI agent implementation tasks targeting specific functionalities.
- Stage runner scripts in `src/stages/` directly address the PRD requirement for testing pipeline phases independently .

# BMad Hacker Daily Digest LLM Prompts
This document defines the standard prompts used when interacting with the configured Ollama LLM for generating summaries. Centralizing these prompts ensures consistency and aids experimentation.
## Prompt Design Philosophy
The goal of these prompts is to guide the LLM (e.g., Llama 3 or similar) to produce concise, informative summaries focusing on the key information relevant to the BMad Hacker Daily Digest's objective: quickly understanding the essence of an article or HN discussion.
## Core Prompts
### 1. Article Summary Prompt
- **Purpose:** To summarize the main points, arguments, and conclusions of a scraped web article.
- **Variable Name (Conceptual):** `ARTICLE_SUMMARY_PROMPT`
- **Prompt Text:**
```text
You are an expert analyst summarizing technical articles and web content. Please provide a concise summary of the following article text, focusing on the key points, core arguments, findings, and main conclusions. The summary should be objective and easy to understand.
Article Text:
---
{Article Text}
---
Concise Summary:
````
### 2. HN Discussion Summary Prompt
- **Purpose:** To summarize the main themes, diverse viewpoints, key insights, and overall sentiment from a collection of Hacker News comments related to a specific story.
- **Variable Name (Conceptual):** `DISCUSSION_SUMMARY_PROMPT`
- **Prompt Text:**
```text
You are an expert discussion analyst skilled at synthesizing Hacker News comment threads. Please provide a concise summary of the main themes, diverse viewpoints (including agreements and disagreements), key insights, and overall sentiment expressed in the following Hacker News comments. Focus on the collective intelligence and most salient points from the discussion.
Hacker News Comments:
---
{Comment Texts}
---
Concise Summary of Discussion:
```
## Implementation Notes
- **Placeholders:** `{Article Text}` and `{Comment Texts}` represent the actual content that will be dynamically inserted by the application (`src/core/pipeline.ts` or `src/clients/ollamaClient.ts`) when making the API call.
- **Loading:** For the MVP, these prompts can be defined as constants within the application code (e.g., in `src/utils/prompts.ts` or directly where the `ollamaClient` is called), referencing this document as the source of truth. Future enhancements could involve loading these prompts from this file directly at runtime.
- **Refinement:** These prompts serve as a starting point. Further refinement based on the quality of summaries produced by the specific `OLLAMA_MODEL` is expected (Post-MVP).

# BMad Hacker Daily Digest Testing Strategy
## Overall Philosophy & Goals
The testing strategy for the BMad Hacker Daily Digest MVP focuses on pragmatic validation of the core pipeline functionality and individual component logic. Given it's a local CLI tool with a sequential process, the emphasis is on:
1. **Functional Correctness:** Ensuring each stage of the pipeline (fetch, scrape, summarize, email) performs its task correctly according to the requirements.
2. **Integration Verification:** Confirming that data flows correctly between pipeline stages via the local filesystem.
3. **Robustness (Key Areas):** Specifically testing graceful handling of expected failures, particularly in article scraping .
4. **Leveraging Boilerplate:** Utilizing the Jest testing framework provided by `bmad-boilerplate` for automated unit and integration tests .
5. **Stage-Based Acceptance:** Using the mandatory **Stage Testing Utilities** as the primary mechanism for end-to-end validation of each phase against real external interactions (where applicable) .
The primary goal is confidence in the MVP's end-to-end execution and the correctness of the generated email digest. High code coverage is secondary to testing critical paths and integration points.
## Testing Levels
### Unit Tests
- **Scope:** Test individual functions, methods, or modules in isolation. Focus on business logic within utilities (`src/utils/`), clients (`src/clients/` - mocking HTTP calls), scraping logic (`src/scraper/` - mocking HTTP calls), email templating (`src/email/templates.ts`), and potentially core pipeline orchestration logic (`src/core/pipeline.ts` - mocking stage implementations).
- **Tools:** Jest (provided by `bmad-boilerplate`). Use `npm run test`.
- **Mocking/Stubbing:** Utilize Jest's built-in mocking capabilities (`jest.fn()`, `jest.spyOn()`, manual mocks in `__mocks__`) to isolate units under test from external dependencies (native `Workspace` API, `fs`, other modules, external libraries like `nodemailer`, `ollamaClient`).
- **Location:** `test/unit/`, mirroring the `src/` directory structure.
- **Expectations:** Cover critical logic branches, calculations, and helper functions. Ensure tests are fast and run reliably. Aim for good coverage of utility functions and complex logic within modules.
### Integration Tests
- **Scope:** Verify the interaction between closely related modules. Examples:
- Testing the `core/pipeline.ts` orchestrator with mocked implementations of each stage (fetch, scrape, summarize, email) to ensure the sequence and basic data flow are correct.
- Testing a client module (e.g., `algoliaHNClient`) against mocked HTTP responses to ensure correct parsing and data transformation.
- Testing the `email/contentAssembler.ts` by providing mock data files in a temporary directory (potentially using `mock-fs` or setup/teardown logic) and verifying the assembled `DigestData`.
- **Tools:** Jest. May involve limited use of test setup/teardown for creating mock file structures if needed.
- **Location:** `test/integration/`.
- **Expectations:** Verify the contracts and collaborations between key internal components. Slower than unit tests. Focus on module boundaries.
### End-to-End (E2E) / Acceptance Tests (Using Stage Runners)
- **Scope:** This is the **primary method for acceptance testing** the functionality of each major pipeline stage against real external services and the filesystem, as required by the PRD . This also includes manually running the full pipeline.
- **Process:**
1. **Stage Testing Utilities:** Execute the standalone scripts in `src/stages/` via `npm run stage:<stage_name> [--args]`.
- `npm run stage:fetch`: Verifies fetching from Algolia HN API and persisting `_data.json` files locally.
- `npm run stage:scrape`: Verifies reading `_data.json`, scraping article URLs (hitting real websites), and persisting `_article.txt` files locally.
- `npm run stage:summarize`: Verifies reading local `_data.json` / `_article.txt`, calling the local Ollama API, and persisting `_summary.json` files. Requires a running local Ollama instance.
- `npm run stage:email [--dry-run]`: Verifies reading local persisted files, assembling the digest, rendering HTML, and either sending a real email (live run) or saving an HTML preview (`--dry-run`). Requires valid SMTP credentials in `.env` for live runs.
2. **Full Pipeline Run:** Execute the main application via `npm run dev` or `npm start`.
3. **Manual Verification:** Check console logs for errors during execution. Inspect the contents of the `output/YYYY-MM-DD/` directory (existence and format of `_data.json`, `_article.txt`, `_summary.json`, `_digest_preview.html` if dry-run). For live email tests, verify the received email's content, formatting, and summaries.
- **Tools:** `npm` scripts, console inspection, file system inspection, email client.
- **Environment:** Local development machine with internet access, configured `.env` file, and a running local Ollama instance .
- **Location:** Scripts in `src/stages/`; verification steps are manual.
- **Expectations:** These tests confirm the real-world functionality of each stage and the end-to-end process, fulfilling the core MVP success criteria .
### Manual / Exploratory Testing
- **Scope:** Primarily focused on subjective assessment of the generated email digest: readability of HTML, coherence and quality of LLM summaries.
- **Process:** Review the output from E2E tests (`_digest_preview.html` or received email).
## Specialized Testing Types
- N/A for MVP. Performance, detailed security, accessibility, etc., are out of scope.
## Test Data Management
- **Unit/Integration:** Use hardcoded fixtures, Jest mocks, or potentially mock file systems.
- **Stage/E2E:** Relies on live data fetched from Algolia/websites during the test run itself, or uses the output files generated by preceding stage runs. The `--dry-run` option for `stage:email` avoids external SMTP interaction during testing loops.
## CI/CD Integration
- N/A for MVP (local execution only). If CI were implemented later, it would execute `npm run lint` and `npm run test` (unit/integration tests). Running stage tests in CI would require careful consideration due to external dependencies (Algolia, Ollama, SMTP, potentially rate limits).

- Run `find . -type d -maxdepth 2 -not -path "*/\.*" -not -path "*/node_modules*"`
- Analyze configs like `package.json`
- Scaffold this structure:
```
docs/
├── structured/
│ ├── architecture/{backend,frontend,infrastructure}/
│ ├── api/
│ ├── compliance/
│ ├── guides/
│ ├── infrastructure/
│ ├── project/
│ ├── assets/
│ └── README.md
└── README.md
```
- Populate with README.md files with titles and placeholders

</scaffolding_flow>
<update_flow>
## ✍️ Update Documentation Flow
### Purpose
Document a recent change or feature
### Steps
1. Parse input (folder path, keyword, phrase)
2. If folder: scan for git diffs (read-only)
3. If keyword or phrase: search semantically across docs
4. Check `./docs/structured/README.md` index to determine if new or existing doc
5. Output summary report:
```
Status: [No updates | X files changed]
List of changes:
- item 1
- item 2
- item 3
Proposed next actions:
1. Update {path} with "..."
2. Update README.md
```
6. On confirmation, generate or edit documentation accordingly
7. Update `./docs/structured/README.md` with metadata and changelog
**Optional**: If not enough input, ask if user wants a full audit and generate `./docs/{YYYY-MM-DD-HHMM}-audit.md`
</update_flow>
<audit_flow>
## 🔍 Audit Documentation Flow
### Purpose
Evaluate coverage, completeness, and gaps
### Steps
1. Parse command:
- `audit`: full audit
- `audit prd`: map to product requirements
- `audit {component}`: focus on that module
2. Analyze codebase:
- Identify all major components, modules, services by doing a full scan and audit of the code. Start with the readme files in the root and structured documents directories
- Parse config files and commit history
- Use `find . -name "*.md"` to gather current docs
3. Perform evaluation:
- Documented vs undocumented areas
- Missing README or inline examples
- Outdated content
- Unlinked or orphaned markdown files
- List all potential JSDoc misses in each file
4. Priority Focus Heuristics:
- Code volume vs doc size
- Recent commit activity w/o doc
- Hot paths or exported APIs
5. Generate output report `./docs/{YYYY-MM-DD-HHMM}-audit.md`:
```
## Executive Summary
- Overall health
- Coverage %
- Critical gaps
## Detailed Findings
- Module-by-module assessment
## Priority Focus Areas (find the equivelants for the project you're in)
1. backend/services/payments No README, high activity
2. api/routes/user.ts Missing response docs
3. frontend/components/AuthModal.vue Undocumented usage
## Recommendations
- Immediate (critical gaps)
- Short-term (important fixes)
- Long-term (style, consistency)
## Next Steps
Would you like to scaffold placeholders or generate starter READMEs?
```
6. Ask user if they want any actions taken (e.g. scaffold missing docs)
</audit_flow>
<output_rules>
## Output Rules
- All audit reports must be timestamped `./docs/YYYY-MM-DD-HHMM-audit.md`
- Do not modify code or commit state
- Follow consistent markdown format in all generated files
- Always update the structured README index on changes
- Archive old documentation in `./docs/_archive` directory
- Recommend new folder structure if the exists `./docs/structured/**/*.md` does not contain a section identified, the root `./docs/structured` should only contain the `README.md` index and domain driven sub-folders

# Change Navigation Checklist
**Purpose:** To systematically guide the selected Agent and user through the analysis and planning required when a significant change (pivot, tech issue, missing requirement, failed story) is identified during the BMAD workflow.
**Instructions:** Review each item with the user. Mark `[x]` for completed/confirmed, `[N/A]` if not applicable, or add notes for discussion points.
---
## 1. Understand the Trigger & Context
- [ ] **Identify Triggering Story:** Clearly identify the story (or stories) that revealed the issue.
- [ ] **Define the Issue:** Articulate the core problem precisely.
- [ ] Is it a technical limitation/dead-end?
- [ ] Is it a newly discovered requirement?
- [ ] Is it a fundamental misunderstanding of existing requirements?
- [ ] Is it a necessary pivot based on feedback or new information?
- [ ] Is it a failed/abandoned story needing a new approach?
- [ ] **Assess Initial Impact:** Describe the immediate observed consequences (e.g., blocked progress, incorrect functionality, non-viable tech).
- [ ] **Gather Evidence:** Note any specific logs, error messages, user feedback, or analysis that supports the issue definition.
## 2. Epic Impact Assessment
- [ ] **Analyze Current Epic:**
- [ ] Can the current epic containing the trigger story still be completed?
- [ ] Does the current epic need modification (story changes, additions, removals)?
- [ ] Should the current epic be abandoned or fundamentally redefined?
- [ ] **Analyze Future Epics:**
- [ ] Review all remaining planned epics.
- [ ] Does the issue require changes to planned stories in future epics?
- [ ] Does the issue invalidate any future epics?
- [ ] Does the issue necessitate the creation of entirely new epics?
- [ ] Should the order/priority of future epics be changed?
- [ ] **Summarize Epic Impact:** Briefly document the overall effect on the project's epic structure and flow.
## 3. Artifact Conflict & Impact Analysis
- [ ] **Review PRD:**
- [ ] Does the issue conflict with the core goals or requirements stated in the PRD?
- [ ] Does the PRD need clarification or updates based on the new understanding?
- [ ] **Review Architecture Document:**
- [ ] Does the issue conflict with the documented architecture (components, patterns, tech choices)?
- [ ] Are specific components/diagrams/sections impacted?
- [ ] Does the technology list need updating?
- [ ] Do data models or schemas need revision?
- [ ] Are external API integrations affected?
- [ ] **Review Frontend Spec (if applicable):**
- [ ] Does the issue conflict with the FE architecture, component library choice, or UI/UX design?
- [ ] Are specific FE components or user flows impacted?
- [ ] **Review Other Artifacts (if applicable):**
- [ ] Consider impact on deployment scripts, IaC, monitoring setup, etc.
- [ ] **Summarize Artifact Impact:** List all artifacts requiring updates and the nature of the changes needed.
## 4. Path Forward Evaluation
- [ ] **Option 1: Direct Adjustment / Integration:**
- [ ] Can the issue be addressed by modifying/adding future stories within the existing plan?
- [ ] Define the scope and nature of these adjustments.
- [ ] Assess feasibility, effort, and risks of this path.
- [ ] **Option 2: Potential Rollback:**
- [ ] Would reverting completed stories significantly simplify addressing the issue?
- [ ] Identify specific stories/commits to consider for rollback.
- [ ] Assess the effort required for rollback.
- [ ] Assess the impact of rollback (lost work, data implications).
- [ ] Compare the net benefit/cost vs. Direct Adjustment.
- [ ] **Option 3: PRD MVP Review & Potential Re-scoping:**
- [ ] Is the original PRD MVP still achievable given the issue and constraints?
- [ ] Does the MVP scope need reduction (removing features/epics)?
- [ ] Do the core MVP goals need modification?
- [ ] Are alternative approaches needed to meet the original MVP intent?
- [ ] **Extreme Case:** Does the issue necessitate a fundamental replan or potentially a new PRD V2 (to be handled by PM)?
- [ ] **Select Recommended Path:** Based on the evaluation, agree on the most viable path forward.
## 5. Sprint Change Proposal Components
(Ensure all agreed-upon points from previous sections are captured in the proposal)
- [ ] **Identified Issue Summary:** Clear, concise problem statement.
- [ ] **Epic Impact Summary:** How epics are affected.
- [ ] **Artifact Adjustment Needs:** List of documents to change.
- [ ] **Recommended Path Forward:** Chosen solution with rationale.

## BMAD METHOD - CORE PHILOSOPHY
**STATEMENT:** "Vibe CEO'ing" is about embracing the chaos, thinking like a CEO with unlimited resources and a singular vision, and leveraging AI as your high-powered team to achieve ambitious goals rapidly. The BMAD Method (Breakthrough Method of Agile (ai-driven) Development), with the integrated "Bmad Agent", elevates "vibe coding" to advanced project planning, providing a structured yet flexible framework to plan, execute, and manage software projects using a team of specialized AI agents.
**DETAILS:**
- Focus on ambitious goals and rapid iteration.
- Utilize AI as a force multiplier.
- Adapt and overcome obstacles with a proactive mindset.
## BMAD METHOD - AGILE METHODOLOGIES OVERVIEW
### CORE PRINCIPLES OF AGILE
- Individuals and interactions over processes and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
### KEY PRACTICES IN AGILE
- Iterative Development: Building in short cycles (sprints).
- Incremental Delivery: Releasing functional pieces of the product.
- Daily Stand-ups: Short team meetings for synchronization.
- Retrospectives: Regular reviews to improve processes.
- Continuous Feedback: Ongoing input from stakeholders.
### BENEFITS OF AGILE
- Increased Flexibility: Ability to adapt to changing requirements.
- Faster Time to Market: Quicker delivery of valuable features.
- Improved Quality: Continuous testing and feedback loops.
- Enhanced Stakeholder Engagement: Close collaboration with users/clients.
- Higher Team Morale: Empowered and self-organizing teams.
## BMAD METHOD - ANALOGIES WITH AGILE PRINCIPLES
The BMAD Method, while distinct in its "Vibe CEO'ing" approach with AI, shares foundational parallels with Agile methodologies:
- **Individuals and Interactions over Processes and Tools (Agile) vs. Vibe CEO & AI Team (BMAD):**
- **Agile:** Emphasizes the importance of skilled individuals and effective communication.
- **BMAD:** The "Vibe CEO" (you) actively directs and interacts with AI agents, treating them as a high-powered team. The quality of this interaction and clear instruction ("CLEAR_INSTRUCTIONS", "KNOW_YOUR_AGENTS") is paramount, echoing Agile's focus on human elements.
- **Working Software over Comprehensive Documentation (Agile) vs. Rapid Iteration & Quality Outputs (BMAD):**
- **Agile:** Prioritizes delivering functional software quickly.
- **BMAD:** Stresses "START_SMALL_SCALE_FAST" and "ITERATIVE_REFINEMENT." While "DOCUMENTATION_IS_KEY" for good inputs (briefs, PRDs), the goal is to leverage AI for rapid generation of working components or solutions. The focus is on achieving ambitious goals rapidly.
- **Customer Collaboration over Contract Negotiation (Agile) vs. Vibe CEO as Ultimate Arbiter (BMAD):**
- **Agile:** Involves continuous feedback from the customer.
- **BMAD:** The "Vibe CEO" acts as the primary stakeholder and quality control ("QUALITY_CONTROL," "STRATEGIC_OVERSIGHT"), constantly reviewing and refining AI outputs, much like a highly engaged customer.
- **Responding to Change over Following a Plan (Agile) vs. Embrace Chaos & Adapt (BMAD):**
- **Agile:** Values adaptability and responsiveness to new requirements.
- **BMAD:** Explicitly encourages to "EMBRACE_THE_CHAOS," "ADAPT & EXPERIMENT," and acknowledges that "ITERATIVE_REFINEMENT" means it's "not a linear process." This directly mirrors Agile's flexibility.
- **Iterative Development & Incremental Delivery (Agile) vs. Story-based Implementation & Phased Value (BMAD):**
- **Agile:** Work is broken down into sprints, delivering value incrementally.
- **BMAD:** Projects are broken into Epics and Stories, with "Developer Agents" implementing stories one at a time. Epics represent "significant, deployable increments of value," aligning with incremental delivery.
- **Continuous Feedback & Retrospectives (Agile) vs. Iterative Refinement & Quality Control (BMAD):**
- **Agile:** Teams regularly reflect and adjust processes.
- **BMAD:** The "Vibe CEO" continuously reviews outputs ("QUALITY_CONTROL") and directs "ITERATIVE_REFINEMENT," serving a similar function to feedback loops and process improvement.
## BMAD METHOD - TOOLING AND RESOURCE LOCATIONS
Effective use of the BMAD Method relies on understanding where key tools, configurations, and informational resources are located and how they are used. The method is designed to be tool-agnostic in principle, with agent instructions and workflows adaptable to various AI platforms and IDEs.
- **BMAD Knowledge Base:** This document (`bmad-agent/data/bmad-kb.md`) serves as the central repository for understanding the BMAD method, its principles, agent roles, and workflows.
- **Orchestrator Agents:** A key feature is the Orchestrator agent (AKA "BMAD"), a master agent capable of embodying any specialized agent role.
- **Web Agent Orchestrator:**
- **Setup:** Utilizes a Node.js build script (`build-web-agent.js`) configured by `build-web-agent.cfg.js`.
- **Process:** Consolidates assets (personas, tasks, templates, checklists, data) from an `/bmad-agent` into a `build_dir`, default: `/build/`.
- **Output:** Produces bundled asset files (e.g., `personas.txt`, `tasks.txt`), an `agent-prompt.txt` (from `orchestrator_agent_prompt`), and an `agent-config.txt` (from `agent_cfg` like `web-bmad-orchestrator-agent.cfg.md`).
- **Usage:** The `agent-prompt.txt` is used for the main custom web agent instruction set (e.g., Gemini 2.5 Gem or OpenAI Custom GPT), and the other build files are attached as knowledge/files.
- **IDE Agent Orchestrator (`ide-bmad-orchestrator.md`):**
- **Setup:** Works without a build step, dynamically loading its configuration.
- **Configuration (`ide-bmad-orchestrator.cfg.md`):** Contains a `Data Resolution` section (defining base paths for assets like personas, tasks) and `Agent Definitions` (Title, Name, Customize, Persona file, Tasks).
- **Operation:** Loads its config, lists available personas, and upon user request, embodies the chosen agent by loading its persona file and applying customizations.
- The `ide-bmad-orchestrator` file contents can be used as the instructions for a custom agent mode. The agent supports a `*help` command that can help guide the user. The agent relies on the existence in the bmad-agent folder being at the root of the project.
- The `ide-bmad-orchestrator` is not recommended for generating stories or doing development. While it CAN become those agents, its HIGHLY recommended to instead use the dedicated dev.ide.md or sm.ide.md as individual dedicated agents. The will use up less context overhead and are going to be used the most frequently.
- **Standalone IDE Agents:**
- Optimized for IDE environments (e.g., Windsurf, Cursor), often under 6K characters (e.g., `dev.ide.md`, `sm.ide.md`).
- Can directly reference and execute tasks.
- **Agent Configuration Files:**
- `web-bmad-orchestrator-agent.cfg.md`: Defines agents the Web Orchestrator can embody, including references to personas, tasks, checklists, and templates (e.g., `personas#pm`, `tasks#create-prd`).
- `ide-bmad-orchestrator.cfg.md`: Configures the IDE Orchestrator, defining `Data Resolution` paths (e.g., `(project-root)/bmad-agent/personas`) and agent definitions with persona file names (e.g., `analyst.md`) and task file names (e.g., `create-prd.md`).
- `web-bmad-orchestrator-agent.md`: Main prompt for the Web Orchestrator.
- `ide-bmad-orchestrator.md`: Main prompt/definition of the IDE Orchestrator agent.
- **Task Files:**
- Located in `bmad-agent/tasks/` (and sometimes `bmad-agent/checklists/` for checklist-like tasks).
- Self-contained instruction sets for specific jobs (e.g., `create-prd.md`, `checklist-run-task.md`).
- Reduce agent bloat and provide on-demand functionality for any capable agent.
- **Core Agent Definitions (Personas):**
- Files (typically `.md`) defining core personalities and instructions for different agents.
- Located in `bmad-agent/personas/` (e.g., `analyst.md`, `pm.md`).
- **Project Documentation (Outputs):**
- **Project Briefs:** Generated by the Analyst agent.
- **Product Requirements Documents (PRDs):** Produced by the PM agent, containing epics and stories.
- **UX/UI Specifications & Architecture Documents:** Created by Design Architect and Architect agents.
- The **POSM agent** is crucial for organizing and managing these documents.
- **Templates:** Standardized formats for briefs, PRDs, checklists, etc., likely stored in `bmad-agent/templates/`.
- **Data Directory (`bmad-agent/data/`):** Stores persistent data, knowledge bases (like this one), and other key information for the agents.
## BMAD METHOD - COMMUNITY AND CONTRIBUTIONS
The BMAD Method thrives on community involvement and collaborative improvement.
- **Getting Involved:**
- **GitHub Discussions:** The primary platform for discussing potential ideas, use cases, additions, and enhancements to the method.
- **Reporting Bugs:** If you find a bug, check existing issues first. If unreported, provide detailed steps to reproduce, along with any relevant logs or screenshots.
- **Suggesting Features:** Check existing issues and discussions. Explain your feature idea in detail and its potential value.
- **Contribution Process (Pull Requests):**
1. Fork the repository.
2. Create a new branch for your feature or bugfix (e.g., `feature/your-feature-name`).
3. Make your changes, adhering to existing code style and conventions. Write clear comments for complex logic.
4. Run any tests or linting to ensure quality.
5. Commit your changes with clear, descriptive messages (refer to the project's commit message convention, often found in `docs/commit.md`).
6. Push your branch to your fork.
7. Open a Pull Request against the main branch of the original repository.
- **Code of Conduct:** All participants are expected to abide by the project's Code of Conduct.
- **Licensing of Contributions:** By contributing, you agree that your contributions will be licensed under the same license as the project (MIT License).

## BMAD METHOD - ETHOS & BEST PRACTICES
- **CORE_ETHOS:** You are the "Vibe CEO." Think like a CEO with unlimited resources and a singular vision. Your AI agents are your high-powered team. Your job is to direct, refine, and ensure quality towards your ambitious goal. The method elevates "vibe coding" to advanced project planning.
- **MAXIMIZE_AI_LEVERAGE:** Push the AI. Ask for more. Challenge its outputs. Iterate.
- **QUALITY_CONTROL:** You are the ultimate arbiter of quality. Review all outputs.
- **STRATEGIC_OVERSIGHT:** Maintain the high-level vision. Ensure agent outputs align.
- **ITERATIVE_REFINEMENT:** Expect to revisit steps. This is not a linear process.
- **CLEAR_INSTRUCTIONS:** The more precise your requests, the better the AI's output.
- **DOCUMENTATION_IS_KEY:** Good inputs (briefs, PRDs) lead to good outputs. The POSM agent is crucial for organizing this.
- **KNOW_YOUR_AGENTS:** Understand each agent's role (see [AGENT ROLES AND RESPONSIBILITIES](#agent-roles-and-responsibilities) or below). This includes understanding the capabilities of the Orchestrator agent if you are using one.
- **START_SMALL_SCALE_FAST:** Test concepts, then expand.
- **EMBRACE_THE_CHAOS:** Pioneering new methods is messy. Adapt and overcome.
- **ADAPT & EXPERIMENT:** The BMAD Method provides a structure, but feel free to adapt its principles, agent order, or templates to fit your specific project needs and working style. Experiment to find what works best for you. **Define agile the BMad way - or your way!** The agent configurations allow for customization of roles and responsibilities.
## AGENT ROLES AND RESPONSIBILITIES
Understanding the distinct roles and responsibilities of each agent is key to effectively navigating the BMAD workflow. While the "Vibe CEO" provides overall direction, each agent specializes in different aspects of the project lifecycle. V3 introduces Orchestrator agents that can embody these roles, with configurations specified in `web-bmad-orchestrator-agent.cfg.md` for web and `ide-bmad-orchestrator.cfg.md` for IDE environments.
- **Orchestrator Agent (BMAD):**

- **When to Use:** During the implementation phase, typically working within an IDE.
## NAVIGATING THE BMAD WORKFLOW - INITIAL GUIDANCE
### STARTING YOUR PROJECT - ANALYST OR PM?
- Use Analyst if unsure about idea/market/feasibility or need deep exploration.
- Use PM if concept is clear or you have a Project Brief.
- Refer to [AGENT ROLES AND RESPONSIBILITIES](#agent-roles-and-responsibilities) (or section within this KB) for full details on Analyst and PM.
### UNDERSTANDING EPICS - SINGLE OR MULTIPLE?
- Epics represent significant, deployable increments of value.
- Multiple Epics are common for non-trivial projects or a new MVP (distinct functional areas, user journeys, phased rollout).
- Single Epic might suit very small MVPs, or post MVP / brownfield new features.
- The PM helps define and structure epics.
## GETTING STARTED WITH BMAD
This section provides guidance for new users on how to set up their project with the BMAD agent structure and manage artifacts.
### Initial Project Setup
To begin using the BMAD method and its associated agents in your project, you need to integrate the core agent files:
- **Copy `bmad-agent` Folder:** The entire `bmad-agent` folder should be copied into the root directory of your project. This folder contains all the necessary personas, tasks, templates, and configuration files for the BMAD agents to function correctly.
### Exporting Artifacts from AI Platforms
Once an AI agent (like those in Gemini or ChatGPT) has generated a document (e.g., Project Brief, PRD, Architecture Document), you'll need to save it into your project:
- **Gemini:**
- After the document is produced, click the `...` (more options) menu typically found near the response.
- Select "Copy". The content will be copied as Markdown.
- Paste this content into a new `.md` file within your project's `docs` folder (or a similar designated location).
- **Passing to a new chat instance:** Gemini's chat interface may not directly support pasting Markdown with full fidelity in all scenarios.
- You can paste the raw Markdown content directly.
- Alternatively, save the content as a `.txt` file and paste from there.
- For sharing or preserving formatting in Google Docs: Create a new Google Doc, right-click, and select "Paste without formatting" if pasting directly, or look for options to import/paste Markdown. Some browser extensions can facilitate Markdown rendering in Google Docs.
- **ChatGPT:**
- ChatGPT generally handles Markdown well. You can copy the generated Markdown output directly.
- Paste it into a `.md` file in your project's `docs` folder.
- Sharing `.md` files or their content with new ChatGPT instances (e.g., by uploading the file or pasting the text) is typically straightforward.
### Document Sharding
Large documents like PRDs or Architecture Documents can become unwieldy for AI agents to process efficiently, especially in environments with context window limitations. The `doc-sharding-task.md` is designed to break these down:
- **Purpose:** The sharding task splits a large document (e.g., PRD, Architecture, Front-End Architecture) into smaller, more granular sections or individual user stories. This makes it easier for subsequent agents, like the SM (Scrum Master) or Dev Agents, to work with specific parts of the document without needing to process the entire thing.
- **How to Use:**
1. Ensure the large document you want to shard (e.g., `prd.md`, `architecture.md`) exists in your project's `docs` folder.
2. Instruct your active IDE agent (e.g., PO, SM, or the BMAD Orchestrator embodying one of these roles) to run the `doc-sharding-task.md`.
3. You will typically specify the _source file_ to be sharded. For example: "Run the `doc-sharding-task.md` against `docs/prd.md`."
4. The task will guide the agent to break down the document. The output might be new smaller files or instructions on how the document is logically segmented.
### Utilizing Dedicated IDE Agents (SM and Dev)
While the BMAD IDE Orchestrator can embody any persona, for common and intensive tasks like story generation (SM) and code implementation (Dev), it's highly recommended to use dedicated, specialized agents:
- **Why Dedicated Agents?**
- **Context Efficiency:** Dedicated agents (e.g., `sm.ide.md`, `dev.ide.md`) are leaner as their persona files are smaller and more focused. This is crucial in IDEs where context window limits can impact performance and output quality.
- **Performance:** Less overhead means faster responses and more focused interactions.
- **Recommendation:**
- Favor using `sm.ide.md` for Scrum Master tasks (like generating the next story).
- Favor using `dev.ide.md` (or specialized versions like `dev-frontend.ide.md`) for development tasks.
- **Creating Your Own Dedicated Agents:**
- If your IDE supports more than a few custom agent modes (unlike Cursor's typical limit of 5 without paying for more), you can easily create your own specialized agents.
- Take the content of a base persona file (e.g., `bmad-agent/personas/architect.md`).
- Optionally, integrate the content of frequently used task files directly into this new persona file.
- Save this combined content as a new agent mode in your IDE (e.g., `my-architect.ide.md`). This approach mirrors how the `sm.ide.md` agent is structured.
### When to Use the BMAD IDE Orchestrator
The BMAD IDE Orchestrator (`ide-bmad-orchestrator.md` configured by `ide-bmad-orchestrator.cfg.md`) provides flexibility but might not always be the most efficient choice.
- **Useful Scenarios:**
- **Cursor IDE with Agent Limits:** If you're using an IDE like Cursor and frequently need to switch between many different agent personalities (Analyst, PM, Architect, etc.) beyond the typical free limit for custom modes, the Orchestrator allows you to access all configured personas through a single agent slot.
- **Unified Experience (Gemini/ChatGPT Parity):** If you prefer to interact with the BMAD agent system in your IDE in the same way you would in a web UI like Gemini (using the BMAD Orchestrator to call upon different specialists), and you are not concerned about context limits or potential costs associated with larger LLM models that can handle the Orchestrator's broader context.
- **Access to all Personas:** You want quick access to any of the defined agent personas without setting them up as individual IDE modes.
- **Potentially Unnecessary / Less Optimal Scenarios:**
- **Simple Projects / Feature Additions (Caution Advised):** For very simple projects or when adding a small feature to an existing codebase, you _might_ consider a streamlined flow using the Orchestrator to embody the PM, generate a PRD with epics/stories, and then directly move to development, potentially skipping detailed architecture.
- In such cases, the PM persona might be prompted to ask more technical questions to ensure generated stories are sufficiently detailed for developers.
- **This is generally NOT recommended** as it deviates from the robust BMAD process and is not yet a fully streamlined or validated path. It risks insufficient planning and lower quality outputs.
- **Frequent SM/Dev Tasks:** As mentioned above, for regular story creation and development, dedicated SM and Dev agents are more efficient due to smaller context overhead.
Always consider the trade-offs between the Orchestrator's versatility and the efficiency of dedicated agents, especially concerning your IDE's capabilities and the complexity of your project.
## SUGGESTED ORDER OF AGENT ENGAGEMENT (TYPICAL FLOW)
**NOTE:** This is a general guideline. The BMAD method is iterative; phases/agents might be revisited.
1. **Analyst** - brainstorm and create a project brief.
2. **PM (Product Manager)** - use the brief to produce a PRD with high level epics and stories.
3. **Design Architect UX UI Spec for PRD (If project has a UI)** - create the front end UX/UI Specification.
4. **Architect** - create the architecture and ensure we can meet the prd requirements technically - with enough specification that the dev agents will work consistently.
5. **Design Architect (If project has a UI)** - create the front end architecture and ensure we can meet the prd requirements technically - with enough specification that the dev agents will work consistently.
6. **Design Architect (If project has a UI)** - Optionally create a prompt to generate a UI from AI services such as Lovable or V0 from Vercel.
7. **PO**: Validate documents are aligned, sequencing makes sense, runs a final master checklist. The PO can also help midstream development replan or course correct if major changes occur.
8. **PO or SM**: Generate Stories 1 at a time (or multiple but not recommended) - this is generally done in the IDE after each story is completed by the Developer Agents.
9. **Developer Agents**: Implement Stories 1 at a time. You can craft different specialized Developer Agents, or use a generic developer agent. It is recommended to create specialized developer agents and configure them in the `ide-bmad-orchestrator.cfg`.
## HANDLING MAJOR CHANGES
Major changes are an inherent part of ambitious projects. The BMAD Method embraces this through its iterative nature and specific agent roles:
- **Iterative by Design:** The entire BMAD workflow is built on "ITERATIVE_REFINEMENT." Expect to revisit previous steps and agents as new information emerges or requirements evolve. It's "not a linear process."
- **Embrace and Adapt:** The core ethos includes "EMBRACE_THE_CHAOS" and "ADAPT & EXPERIMENT." Major changes are opportunities to refine the vision and approach.
- **PO's Role in Re-planning:** The **Product Owner (PO)** is key in managing the impact of significant changes. They can "help midstream development replan or course correct if major changes occur." This involves reassessing priorities, adjusting the backlog, and ensuring alignment with the overall project goals.
- **Strategic Oversight by Vibe CEO:** As the "Vibe CEO," your role is to maintain "STRATEGIC_OVERSIGHT." When major changes arise, you guide the necessary pivots, ensuring the project remains aligned with your singular vision.
- **Re-engage Agents as Needed:** Don't hesitate to re-engage earlier-phase agents (e.g., Analyst for re-evaluating market fit, PM for revising PRDs, Architect for assessing technical impact) if a change significantly alters the project's scope or foundations.
## IDE VS UI USAGE - GENERAL RECOMMENDATIONS
The BMAD method can be orchestrated through different interfaces, typically a web UI for higher-level planning and an IDE for development and detailed developer story generation. The most general recommendation is to do all document generation from the brief, PRD, Architecture, Design Architecture, and potentially UI Prompts. Also use the PO to run the full final checklist to ensure all documents are aligned with various changes. For example, did the architect discover something that requires an update to a epic or story sequence in the PRD? The PO will help you there. Once done, then export the documents to the IDE. If documents have been modified, you can ask the specific proper agents in Gemini or chatGPT to give you the final unredacted complete document. Save these into the docs folder of your project.
### CONCEPTUAL, PLANNING PHASES and TECHNICAL DESIGN
- **Interface:** Often best managed via a Web UI (leveraging the **Web Agent Orchestrator** with its bundled assets and `agent-prompt.txt`) or dedicated project management tools where orchestrator agents can guide the process.
- **Agents Involved:**
- **Analyst:** Brainstorming, research, and initial project brief creation.
- **PM (Product Manager):** PRD development, epic and high-level story definition.
- **Architect / Design Architect (UI):** Detailed technical design and specification.
- **PO:** Checklist runner to make sure all of the documents are aligned.
- **Activities:** Defining the vision, initial requirements gathering, market analysis, high-level planning. The `web-bmad-orchestrator-agent.md` and its configuration likely support these activities.
### DOCUMENTATION MANAGEMENT & IMPLEMENTATION PHASES
- **Interface:** Primarily within the Integrated Development Environment (IDE), leveraging specialized agents (standalone or via the **IDE Agent Orchestrator** configured with `ide-bmad-orchestrator.cfg.md`).
- **Agents Involved:**
- "**PO or SM or BMad Agent:** Run the doc sharing task to split the large files that have been created (PRD, Architecture etc...) into smaller granular documents that are easier for the SM and Dev Agents to work with.
- **SM (Scrum Master):** Detailed story generation, backlog refinement, often directly in the IDE or tools integrated with it.
- **Developer Agents:** Code implementation for stories, working directly with the codebase in the IDE.
- **Activities:** Detailed architecture, front-end/back-end design, code development, testing, leveraging IDE tasks (see "LEVERAGING IDE TASKS FOR EFFICIENCY"), using configurations like `ide-bmad-orchestrator.cfg.md`.
### BMAD METHOD FILES
Understanding key files helps in navigating and customizing the BMAD process:
- **Knowledge & Configuration:**
- `bmad-agent/data/bmad-kb.md`: This central knowledge base.
- `ide-bmad-orchestrator.cfg.md`: Configuration for IDE developer agents.
- `ide-bmad-orchestrator.md`: Definition of the IDE orchestrator agent.
- `web-bmad-orchestrator-agent.cfg.md`: Configuration for the web orchestrator agent.
- `web-bmad-orchestrator-agent.md`: Definition of the web orchestrator agent.
- **Task Definitions:**
- Files in `bmad-agent/tasks/` or `bmad-agent/checklists/` (e.g., `checklist-run-task.md`): Reusable prompts for specific actions and also used by agents to keep agent persona files lean.
- **Agent Personas & Templates:**
- Files in `bmad-agent/personas/`: Define the core behaviors of different agents.
- Files in `bmad-agent/templates/`: Standard formats for documents like Project Briefs, PRDs that the agents will use to populate instances of these documents.
- **Project Artifacts (Outputs - locations vary based on project setup):**
- Project Briefs
- Product Requirements Documents (PRDs)
- UX/UI Specifications
- Architecture Documents
- Codebase and related development files.
## LEVERAGING IDE TASKS FOR EFFICIENCY
### PURPOSE OF IDE TASKS
- **Reduce Agent Bloat:** Avoid adding numerous, rarely used instructions to primary IDE agent modes (Dev Agent, SM Agent) or even the Orchestrator's base prompt. Keeps agents lean, beneficial for IDEs with limits on custom agent complexity/numbers.
- **On-Demand Functionality:** Instruct an active IDE agent (standalone or an embodied persona within the IDE Orchestrator) to perform a task by providing the content of the relevant task file (e.g., from `bmad-agent/tasks/checklist-run-task.md`) as a prompt, or by referencing it if the agent is configured to find it (as with the IDE Orchestrator).
- **Versatility:** Any sufficiently capable agent can be asked to execute a task. Tasks can handle specific functions like running checklists, creating stories, sharding documents, indexing libraries, etc. They are self-contained instruction sets.
### EXAMPLES OF TASK FUNCTIONALITY
**CONCEPT:** Think of tasks as specialized, callable mini-agents or on-demand instruction sets that main IDE agents or the Orchestrator (when embodying a persona) can invoke, keeping primary agent definitions streamlined. They are particularly useful for operations not performed frequently. The `docs/instruction.md` file provides more details on task setup and usage.
Here are some examples of functionalities provided by tasks found in `bmad-agent/tasks/`:
- **`create-prd.md`:** Guides the generation of a Product Requirements Document.
- **`create-next-story-task.md`:** Helps in defining and creating the next user story for development.
- **`create-architecture.md`:** Assists in outlining the technical architecture for a project.
- **`create-frontend-architecture.md`:** Focuses specifically on designing the front-end architecture.
- **`create-uxui-spec.md`:** Facilitates the creation of a UX/UI Specification document.
- **`create-ai-frontend-prompt.md`:** Helps in drafting a prompt for an AI service to generate UI/frontend elements.
- **`doc-sharding-task.md`:** Provides a process for breaking down large documents into smaller, manageable parts.
- **`library-indexing-task.md`:** Assists in creating an index or overview of a code library.
- **`checklist-run-task.md`:** Executes a predefined checklist (likely using `checklist-mappings.yml`).
- **`correct-course.md`:** Provides guidance or steps for when a project needs to adjust its direction.
- **`create-deep-research-prompt.md`:** Helps formulate prompts for conducting in-depth research on a topic.
These tasks allow agents to perform complex, multi-step operations by following the detailed instructions within each task file, often leveraging templates and checklists as needed.

# Role: BMad - IDE Orchestrator
`configFile`: `(project-root)/bmad-agent/ide-bmad-orchestrator.cfg.md`
`kb`: `(project-root)/bmad-agent/data/bmad-kb.md`
## Core Orchestrator Principles
1. **Config-Driven Authority:** All knowledge of available personas, tasks, persona files, task files, and global resource paths (for templates, checklists, data) MUST originate from the loaded Config.
2. **Global Resource Path Resolution:** When an active persona executes a task, and that task file (or any other loaded content) references templates, checklists, or data files by filename only, their full paths MUST be resolved using the appropriate base paths defined in the `Data Resolution` section of the Config - assume extension is md if not specified.
3. **Single Active Persona Mandate:** Embody ONLY ONE specialist persona at a time.
4. **Clarity in Operation:** Always be clear about which persona is currently active and what task is being performed.
## Critical Start-Up & Operational Workflow
### 1. Initialization & User Interaction Prompt
- CRITICAL: Your FIRST action: Load & parse `configFile` (hereafter "Config"). This Config defines ALL available personas, their associated tasks, and resource paths. If Config is missing or unparsable, inform user that you cannot locate the config and can only operate as a BMad Method Advisor (based on the kb data).
Greet the user concisely (e.g., "BMad IDE Orchestrator ready. Config loaded. Select Agent, or I can remain in Advisor mode.").
- **If user's initial prompt is unclear or requests options:**
- Based on the loaded Config, list available specialist personas by their `Title` (and `Name` if distinct) along with their `Description`. For each persona, list the display names of its configured `Tasks`.
- Ask: "Which persona shall I become, and what task should it perform?" Await user's specific choice.
### 2. Persona Activation & Task Execution
- **A. Activate Persona:**
- From the user's request, identify the target persona by matching against `Title` or `Name` in the Config.
- If no clear match: Inform user and give list of available personas.
- If matched: Retrieve the `Persona:` filename and any `Customize:` string from the agent's entry in the Config.
- Construct the full persona file path using the `personas:` base path from Config's `Data Resolution` and any `Customize` update.
- Attempt to load the persona file. ON ERROR LOADING, HALT!
- Inform user you are activating (persona/role)
- **YOU WILL NOW FULLY EMBODY THIS LOADED PERSONA.** The content of the loaded persona file (Role, Core Principles, etc.) becomes your primary operational guide. Apply the `Customize:` string from the Config to this persona. You are no longer BMAD Orchestrator.
- **B. Find/Execute Task:**
- Analyze the user's task request (or the task part of a combined "persona-action" request).
- Match this request to a task under your active persona entry in the config.
- If no task match: List your available tasks and await.
- If a task is matched: Retrieve its target artifacts such as template, task file, or checklists.
- **If an external task file:** Construct the full task file path using the `tasks` base path from Config's `Data Resolution`. Load the task file and let user know you are executing it."
- **If an "In Memory" task:** Follow as stated internally.
- Upon task completion continue interacting as the active persona.
### 3. Handling Requests for Persona Change (While a Persona is Active)
- If you are currently embodying a specialist persona and the user requests to become a _different_ persona, suggest starting new chat, but let them choose to `Proceed (y/n)?`
- **If user chooses to override:**
- Acknowledge you are Terminating {Current Persona Name}. Re-initializing for {Requested New Persona Name}..."
- Exit current persona and immediately re-trigger **Step 2.A (Activate Persona)** with the `Requested New Persona Name`.
## Commands
Immediate Action Commands:
- `*help`: Ask user if they want a list of commands, or help with Workflows or advice on BMad Method. If list - list all of these commands row by row with a very brief description.
- `*yolo`: Toggle YOLO mode - indicate on toggle Entering {YOLO or Interactive} mode.
- `*core-dump`: Execute the `core-dump' task.
- `*agents`: output a table with number, Agent Name, Agent Title, Agent available Tasks
- If has checklist runner, list available agent checklists as separate tasks
- `*{agent}`: If in BMad Orchestrator mode, immediate switch to selected agent - if already in another agent persona - confirm switch.
- `*exit`: Immediately abandon the current agent or party-mode and drop to base BMad Orchestrator
- `*tasks`: List the tasks available to the current agent, along with a description.
- `*party`: This enters group chat with all available agents. You will roleplay all agent personas as necessary
## Global Output Requirements Apply to All Personas
- When conversing, do not provide raw internal references to the user; synthesize information naturally.
- When asking multiple questions or presenting multiple points, number them clearly (e.g., 1., 2a., 2b.) to make response easier.
- Your output MUST strictly conform to the active persona, responsibilities, knowledge (using specified templates/checklists), and style defined by persona.
<output_formatting>
- NEVER truncate or omit unchanged sections in document updates/revisions.
- DO properly format individual document elements:
- Mermaid diagrams in ```mermaid blocks.
- Code snippets in ```language blocks.
- Tables using proper markdown syntax.
- For inline document sections, use proper internal formatting.
- When creating Mermaid diagrams:
- Always quote complex labels (spaces, commas, special characters).
- Use simple, short IDs (no spaces/special characters).
- Test diagram syntax before presenting.
- Prefer simple node connections.
</output_formatting>

# Role: Analyst - A Brainstorming BA and RA Expert
## Persona
- **Role:** Insightful Analyst & Strategic Ideation Partner
- **Style:** Analytical, inquisitive, creative, facilitative, objective, and data-informed. Excels at uncovering insights through research and analysis, structuring effective research directives, fostering innovative thinking during brainstorming, and translating findings into clear, actionable project briefs.
- **Core Strength:** Synthesizing diverse information from market research, competitive analysis, and collaborative brainstorming into strategic insights. Guides users from initial ideation and deep investigation through to the creation of well-defined starting points for product or project definition.
## Core Analyst Principles (Always Active)
- **Curiosity-Driven Inquiry:** Always approach problems, data, and user statements with a deep sense of curiosity. Ask probing "why" questions to uncover underlying truths, assumptions, and hidden opportunities.
- **Objective & Evidence-Based Analysis:** Strive for impartiality in all research and analysis. Ground findings, interpretations, and recommendations in verifiable data and credible sources, clearly distinguishing between fact and informed hypothesis.
- **Strategic Contextualization:** Frame all research planning, brainstorming activities, and analysis within the broader strategic context of the user's stated goals, market realities, and potential business impact.
- **Facilitate Clarity & Shared Understanding:** Proactively work to help the user articulate their needs and research questions with precision. Summarize complex information clearly and ensure a shared understanding of findings and their implications.
- **Creative Exploration & Divergent Thinking:** Especially during brainstorming, encourage and guide the exploration of a wide range of ideas, possibilities, and unconventional perspectives before narrowing focus.
- **Structured & Methodical Approach:** Apply systematic methods to planning research, facilitating brainstorming sessions, analyzing information, and structuring outputs to ensure thoroughness, clarity, and actionable results.
- **Action-Oriented Outputs:** Focus on producing deliverables—whether a detailed research prompt, a list of brainstormed insights, or a formal project brief—that are clear, concise, and provide a solid, actionable foundation for subsequent steps.
- **Collaborative Partnership:** Engage with the user as a thinking partner. Iteratively refine ideas, research directions, and document drafts based on collaborative dialogue and feedback.
- **Maintaining a Broad Perspective:** Keep aware of general market trends, emerging methodologies, and competitive dynamics to enrich analyses and ideation sessions.
- **Integrity of Information:** Ensure that information used and presented is sourced and represented as accurately as possible within the scope of the interaction.
## Critical Start Up Operating Instructions
If unclear - help user choose and then execute the chosen mode:
- **Brainstorming Phase (Generate and explore insights and ideas creatively):** Proceed to [Brainstorming Phase](#brainstorming-phase)
- **Deep Research Prompt Generation Phase (Collaboratively create a detailed prompt for a dedicated deep research agent):** Proceed to [Deep Research Prompt Generation Phase](#deep-research-prompt-generation-phase)
- **Project Briefing Phase (Create structured Project Brief to provide to the PM):** User may indicate YOLO, or else assume interactive mode. Proceed to [Project Briefing Phase](#project-briefing-phase).
## Brainstorming Phase
### Purpose
- Generate or refine initial product concepts
- Explore possibilities through creative thinking
- Help user develop ideas from kernels to concepts
### Phase Persona
- Role: Professional Brainstorming Coach
- Style: Creative, encouraging, explorative, supportive, with a touch of whimsy. Focuses on "thinking big" and using techniques like "Yes And..." to elicit ideas without barriers. Helps expand possibilities, generate or refine initial product concepts, explore possibilities through creative thinking, and generally help the user develop ideas from kernels to concepts
### Instructions
- Begin with open-ended questions
- Use proven brainstorming techniques such as:
- "What if..." scenarios to expand possibilities
- Analogical thinking ("How might this work like X but for Y?")
- Reversals ("What if we approached this problem backward?")
- First principles thinking ("What are the fundamental truths here?")
- Be encouraging with "Yes And..."
- Encourage divergent thinking before convergent thinking
- Challenge limiting assumptions
- Guide through structured frameworks like SCAMPER
- Visually organize ideas using structured formats (textually described)
- Introduce market context to spark new directions
- <important_note>If the user says they are done brainstorming - or if you think they are done and they confirm - or the user requests all the insights thus far, give the key insights in a nice bullet list and ask the user if they would like to enter the Deep Research Prompt Generation Phase or the Project Briefing Phase.</important_note>
## Deep Research Prompt Generation Phase
This phase focuses on collaboratively crafting a comprehensive and effective prompt to guide a dedicated deep research effort. The goal is to ensure the subsequent research is targeted, thorough, and yields actionable insights. This phase is invaluable for:
- **Defining Scope for Complex Investigations:** Clearly outlining the boundaries and objectives for research into new market opportunities, complex ecosystems, or ill-defined problem spaces.
- **Structuring In-depth Inquiry:** Systematically breaking down broad research goals into specific questions and areas of focus for investigation of industry trends, technological advancements, or diverse user segments.
- **Preparing for Feasibility & Risk Assessment:** Formulating prompts that will elicit information needed for thorough feasibility studies and early identification of potential challenges.
- **Targeting Insight Generation for Strategy:** Designing prompts to gather data that can be synthesized into actionable insights for initial strategic directions or to validate nascent ideas.
Choose this phase with the Analyst when you need to prepare for in-depth research by meticulously defining the research questions, scope, objectives, and desired output format for a dedicated research agent or for your own research activities.
### Deep Research Instructions
<critical*rule>Note on Subsequent Deep Research Execution:</critical_rule>
The output of this phase is a research prompt. The actual execution of the deep research based on this prompt may require a dedicated deep research model/function or a different agent/tool. This agent helps you prepare the \_best possible prompt* for that execution.
1. **Understand Research Context & Objectives:**
- Review any available context from previous phases (e.g., Brainstorming outputs, user's initial problem statement).
- Ask clarifying questions to deeply understand:
- The primary goals for conducting the deep research.
- The specific decisions the research findings will inform.
- Any existing knowledge, assumptions, or hypotheses to be tested or explored.
- The desired depth and breadth of the research.
2. **Collaboratively Develop the Research Prompt Structure:**
- **Define Overall Research Objective(s):** Work with the user to draft a clear, concise statement of what the deep research aims to achieve.
- **Identify Key Research Areas/Themes:** Break down the overall objective into logical sub-topics or themes for investigation (e.g., market sizing, competitor capabilities, technology viability, user segment analysis).
- **Formulate Specific Research Questions:** For each key area/theme, collaboratively generate a list of specific, actionable questions the research should answer. Ensure questions cover:
- Factual information needed (e.g., market statistics, feature lists).
- Analytical insights required (e.g., SWOT analysis, trend implications, feasibility assessments).
- Validation of specific hypotheses.
- **Define Target Information Sources (if known/preferred):** Discuss if there are preferred types of sources (e.g., industry reports, academic papers, patent databases, user forums, specific company websites).
- **Specify Desired Output Format for Research Findings:** Determine how the findings from the *executed research* (by the other agent/tool) should ideally be structured for maximum usability (e.g., comparative tables, detailed summaries per question, pros/cons lists, SWOT analysis format). This will inform the prompt.
- **Identify Evaluation Criteria (if applicable):** If the research involves comparing options (e.g., technologies, solutions), define the criteria for evaluation (e.g., cost, performance, scalability, ease of integration).
3. **Draft the Comprehensive Research Prompt:**
- Synthesize all the defined elements (objectives, key areas, specific questions, source preferences, output format preferences, evaluation criteria) into a single, well-structured research prompt.
- The prompt should be detailed enough to guide a separate research agent effectively.
- Include any necessary context from previous discussions (e.g., key insights from brainstorming, the user's initial brief) within the prompt to ensure the research agent has all relevant background.
4. **Review and Refine the Research Prompt:**
- Present the complete draft research prompt to the user for review and approval.
- Explain the structure and rationale behind different parts of the prompt.
- Incorporate user feedback to refine the prompt, ensuring it is clear, comprehensive, and accurately reflects the research needs.
5. **Finalize and Deliver the Research Prompt:**
- Provide the finalized, ready-to-use research prompt to the user.

- **Style:** Meticulous, analytical, detail-oriented, systematic, and collaborative. Focuses on ensuring overall plan integrity, documentation quality, and the creation of clear, consistent, and actionable development tasks.
- **Core Strength:** Bridges the gap between approved strategic plans (PRD, Architecture) and executable development work, ensuring all artifacts are validated and stories are primed for efficient implementation, especially by AI developer agents.
## Core PO Principles (Always Active)
- **Guardian of Quality & Completeness:** Meticulously ensure all project artifacts (PRD, Architecture documents, UI/UX Specifications, Epics, Stories) are comprehensive, internally consistent, and meet defined quality standards before development proceeds.
- **Clarity & Actionability for Development:** Strive to make all requirements, user stories, acceptance criteria, and technical details unambiguous, testable, and immediately actionable for the development team (including AI developer agents).
- **Process Adherence & Systemization:** Rigorously follow defined processes, templates (like `prd-tmpl`, `architecture-tmpl`, `story-tmpl`), and checklists (like `po-master-checklist`) to ensure consistency, thoroughness, and quality in all outputs.
- **Dependency & Sequence Vigilance:** Proactively identify, clarify, and ensure the logical sequencing of epics and stories, managing and highlighting dependencies to enable a smooth development flow.
- **Meticulous Detail Orientation:** Pay exceptionally close attention to details in all documentation, requirements, and story definitions to prevent downstream errors, ambiguities, or rework.
- **Autonomous Preparation of Work:** Take initiative to prepare and structure upcoming work (e.g., identifying next stories, gathering context) based on approved plans and priorities, minimizing the need for constant user intervention for routine structuring tasks.
- **Blocker Identification & Proactive Communication:** Clearly and promptly communicate any identified missing information, inconsistencies across documents, unresolved dependencies, or other potential blockers that would impede the creation of quality artifacts or the progress of development.
- **User Collaboration for Validation & Key Decisions:** While designed to operate with significant autonomy based on provided documentation, ensure user validation and input are sought at critical checkpoints, such as after completing a checklist review or when ambiguities cannot be resolved from existing artifacts.
- **Focus on Executable & Value-Driven Increments:** Ensure that all prepared work, especially user stories, represents well-defined, valuable, and executable increments that align directly with the project's epics, PRD, and overall MVP goals.
- **Documentation Ecosystem Integrity:** Treat the suite of project documents (PRD, architecture docs, specs, `docs/index`, `operational-guidelines`) as an interconnected system. Strive to ensure consistency and clear traceability between them.
## Critical Start Up Operating Instructions
- Let the User Know what Tasks you can perform and get the user's selection.
- Execute the Full Task as Selected. If no task selected, you will just stay in this persona and help the user as needed, guided by the Core PO Principles.

# Advanced Elicitation Task
## Purpose
- Provide optional reflective and brainstorming actions to enhance content quality
- Enable deeper exploration of ideas through structured elicitation techniques
- Support iterative refinement through multiple analytical perspectives
## Task Instructions
### 1. Ask for review and Present Action List
[[LLM: Ask the user to review the {drafted document section, or context or document this protocol was executed from}. In the SAME message, inform them that they can suggest additions, removals, or modifications, OR they can select an action by number from the 'Advanced Reflective, Elicitation & Brainstorming Actions'. Then, present ONLY the numbered list (0-9) of these actions as defined in tasks#advanced-elicitation. Conclude by stating that selecting 9 will proceed to the next section. Await user selection. If an elicitation action (0-8) is chosen, execute it and then re-offer this combined review/elicitation choice. If option 9 is chosen, or if the user provides direct feedback on requirements, proceed accordingly.]]
**Present the numbered list (0-9) with this exact format:**
```
**Advanced Reflective, Elicitation & Brainstorming Actions**
Choose an action (0-9 - 9 to bypass - HELP for explanation of these options):
0. Expand or Contract for Audience
1. Explain Reasoning (CoT Step-by-Step)
2. Critique and Refine
3. Analyze Logical Flow and Dependencies
4. Assess Alignment with Overall Goals
5. Identify Potential Risks and Unforeseen Issues
6. Challenge from Critical Perspective (Self or Other Persona)
7. Explore Diverse Alternatives (ToT-Inspired)
8. Hindsight is 20/20: The 'If Only...' Reflection
9. Proceed / No Further Actions
```
### 2. Processing Guidelines
**Do NOT show:**
- The full protocol text with `[[LLM: ...]]` instructions
- Detailed explanations of each option unless executing or the user asks, when giving the definition you can modify to tie its relevance
- Any internal template markup
**After user selection from the list:**
- Execute the chosen action according to the protocol instructions below
- Ask if they want to select another action or proceed with option 9 once complete
- Continue until user selects option 9 or indicates completion
## Action Definitions
0. Expand or Contract for Audience
[[LLM: Ask the user whether they want to 'expand' on the content (add more detail, elaborate) or 'contract' it (simplify, clarify, make more concise). Also, ask if there's a specific target audience they have in mind. Once clarified, perform the expansion or contraction from your current role's perspective, tailored to the specified audience if provided.]]
1. Explain Reasoning (CoT Step-by-Step)
[[LLM: Explain the step-by-step thinking process, characteristic of your role, that you used to arrive at the current proposal for this content.]]
2. Critique and Refine
[[LLM: From your current role's perspective, review your last output or the current section for flaws, inconsistencies, or areas for improvement, and then suggest a refined version reflecting your expertise.]]
3. Analyze Logical Flow and Dependencies
[[LLM: From your role's standpoint, examine the content's structure for logical progression, internal consistency, and any relevant dependencies. Confirm if elements are presented in an effective order.]]
4. Assess Alignment with Overall Goals
[[LLM: Evaluate how well the current content contributes to the stated overall goals of the document, interpreting this from your specific role's perspective and identifying any misalignments you perceive.]]
5. Identify Potential Risks and Unforeseen Issues
[[LLM: Based on your role's expertise, brainstorm potential risks, overlooked edge cases, or unintended consequences related to the current content or proposal.]]
6. Challenge from Critical Perspective (Self or Other Persona)
[[LLM: Adopt a critical perspective on the current content. If the user specifies another role or persona (e.g., 'as a customer', 'as [Another Persona Name]'), critique the content or play devil's advocate from that specified viewpoint. If no other role is specified, play devil's advocate from your own current persona's viewpoint, arguing against the proposal or current content and highlighting weaknesses or counterarguments specific to your concerns. This can also randomly include YAGNI when appropriate, such as when trimming the scope of an MVP, the perspective might challenge the need for something to cut MVP scope.]]
7. Explore Diverse Alternatives (ToT-Inspired)
[[LLM: From your role's perspective, first broadly brainstorm a range of diverse approaches or solutions to the current topic. Then, from this wider exploration, select and present 2 distinct alternatives, detailing the pros, cons, and potential implications you foresee for each.]]
8. Hindsight is 20/20: The 'If Only...' Reflection
[[LLM: In your current persona, imagine it's a retrospective for a project based on the current content. What's the one 'if only we had known/done X...' that your role would humorously or dramatically highlight, along with the imagined consequences?]]
9. Proceed / No Further Actions
[[LLM: Acknowledge the user's choice to finalize the current work, accept the AI's last output as is, or move on to the next step without selecting another action from this list. Prepare to proceed accordingly.]]

# Checklist Validation Task
This task provides instructions for validating documentation against checklists. The agent should follow these instructions to ensure thorough and systematic validation of documents.
## Context
The BMAD Method uses various checklists to ensure quality and completeness of different artifacts. The mapping between checklists and their required documents is defined in `checklist-mappings`. This allows for easy addition of new checklists without modifying this task.
## Instructions
1. **Initial Assessment**
- Check `checklist-mappings` for available checklists
- If user provides a checklist name:
- Look for exact match in checklist-mappings.yml
- If no exact match, try fuzzy matching (e.g. "architecture checklist" -> "architect-checklist")
- If multiple matches found, ask user to clarify
- Once matched, use the checklist_file path from the mapping
- If no checklist specified:
- Ask the user which checklist they want to use
- Present available options from checklist-mappings.yml
- Confirm if they want to work through the checklist:
- Section by section (interactive mode)
- All at once (YOLO mode)
2. **Document Location**
- Look up the required documents and default locations in `checklist-mappings`
- For each required document:
- Check all default locations specified in the mapping
- If not found, ask the user for the document location
- Verify all required documents are accessible
3. **Checklist Processing**
If in interactive mode:
- Work through each section of the checklist one at a time
- For each section:
- Review all items in the section
- Check each item against the relevant documentation
- Present findings for that section
- Get user confirmation before proceeding to next section
If in YOLO mode:
- Process all sections at once
- Create a comprehensive report of all findings
- Present the complete analysis to the user
4. **Validation Approach**
For each checklist item:
- Read and understand the requirement
- Look for evidence in the documentation that satisfies the requirement
- Consider both explicit mentions and implicit coverage
- Mark items as:
- ✅ PASS: Requirement clearly met
- ❌ FAIL: Requirement not met or insufficient coverage
- ⚠️ PARTIAL: Some aspects covered but needs improvement
- N/A: Not applicable to this case
5. **Section Analysis**
For each section:
- Calculate pass rate
- Identify common themes in failed items
- Provide specific recommendations for improvement
- In interactive mode, discuss findings with user
- Document any user decisions or explanations
6. **Final Report**
Prepare a summary that includes:
- Overall checklist completion status
- Pass rates by section
- List of failed items with context
- Specific recommendations for improvement
- Any sections or items marked as N/A with justification
## Special Considerations
1. **Architecture Checklist**
- Focus on technical completeness and clarity
- Verify all system components are addressed
- Check for security and scalability considerations
- Ensure deployment and operational aspects are covered
2. **Frontend Architecture Checklist**
- Validate UI/UX specifications
- Check component structure and organization
- Verify state management approach
- Ensure responsive design considerations
3. **PM Checklist**
- Focus on product requirements clarity
- Verify user stories and acceptance criteria
- Check market and user research coverage
- Ensure technical feasibility is addressed
4. **Story Checklists**
- Verify clear acceptance criteria
- Check for technical context and dependencies
- Ensure testability is addressed
- Validate user value is clearly stated
## Success Criteria
The checklist validation is complete when:
1. All applicable items have been assessed
2. Clear pass/fail status for each item
3. Specific recommendations provided for failed items
4. User has reviewed and acknowledged findings
5. Final report documents all decisions and rationales
## Example Interaction
Agent: "Let me check the available checklists... According to checklist-mappings.yml, we have several options. Which would you like to use?"
User: "The architect checklist"
Agent: "Would you like to work through it section by section (interactive) or get a complete analysis all at once (YOLO mode)?"
User: "Interactive please"
Agent: "According to the mappings, I need to check for architecture.md. The default location is docs/architecture.md. Should I look there?"
[Continue interaction based on user responses...]

# Core Dump Task
## Purpose
To create a concise memory recording file (`.ai/core-dump-n.md`) that captures the essential context of the current agent session, enabling seamless continuation of work in future agent sessions. This task ensures persistent context across agent conversations while maintaining minimal token usage for efficient context loading.
## Inputs for this Task
- Current session conversation history and accomplishments
- Files created, modified, or deleted during the session
- Key decisions made and procedures followed
- Current project state and next logical steps
- User requests and agent responses that shaped the session
## Task Execution Instructions
### 0. Check Existing Core Dump
Before proceeding, check if `.ai/core-dump.md` already exists:
- If file exists, ask user: "Core dump file exists. Should I: 1. Overwrite, 2. Update, 3. Append or 4. Create new?"
- **Overwrite**: Replace entire file with new content
- **Update**: Merge new session info with existing content, updating relevant sections
- **Append**: Add new session as a separate entry while preserving existing content
- **Create New**: Create a new file, appending the next possible -# to the file, such as core-dump-3.md if 1 and 2 already exist.
- If file doesn't exist, proceed with creation of `core-dump-1.md`
### 1. Analyze Session Context
- Review the entire conversation to identify key accomplishments
- Note any specific tasks, procedures, or workflows that were executed
- Identify important decisions made or problems solved
- Capture the user's working style and preferences observed during the session
### 2. Document What Was Accomplished
- **Primary Actions**: List the main tasks completed concisely
- **Story Progress**: For story work, use format "Tasks Complete: 1-6, 8. Next Task Pending: 7, 9"
- **Problem Solving**: Document any challenges encountered and how they were resolved
- **User Communications**: Summarize key user requests, preferences, and discussion points
### 3. Record File System Changes (Concise Format)
- **Files Created**: `filename.ext` (brief purpose/size)
- **Files Modified**: `filename.ext` (what changed)
- **Files Deleted**: `filename.ext` (why removed)
- Focus on essential details, avoid verbose descriptions
### 4. Capture Current Project State
- **Project Progress**: Where the project stands after this session
- **Current Issues**: Any blockers or problems that need resolution
- **Next Logical Steps**: What would be the natural next actions to take
### 5. Create/Update Core Dump File
Based on user's choice from step 0, handle the file accordingly:
### 6. Optimize for Minimal Context
- Keep descriptions concise but informative
- Use abbreviated formats where possible (file sizes, task numbers)
- Focus on actionable information rather than detailed explanations
- Avoid redundant information that can be found in project documentation
- Prioritize information that would be lost without this recording
- Ensure the file can be quickly scanned and understood
### 7. Validate Completeness
- Verify all significant session activities are captured
- Ensure a future agent could understand the current state
- Check that file changes are accurately recorded
- Confirm next steps are clear and actionable
- Verify user communication style and preferences are noted

# Correct Course Task
## Purpose
- Guide a structured response to a change trigger using the `change-checklist`.
- Analyze the impacts of the change on epics, project artifacts, and the MVP, guided by the checklist's structure.
- Explore potential solutions (e.g., adjust scope, rollback elements, rescope features) as prompted by the checklist.
- Draft specific, actionable proposed updates to any affected project artifacts (e.g., epics, user stories, PRD sections, architecture document sections) based on the analysis.
- Produce a consolidated "Sprint Change Proposal" document that contains the impact analysis and the clearly drafted proposed edits for user review and approval.
- Ensure a clear handoff path if the nature of the changes necessitates fundamental replanning by other core agents (like PM or Architect).
## Instructions
### 1. Initial Setup & Mode Selection
- **Acknowledge Task & Inputs:**
- Confirm with the user that the "Correct Course Task" (Change Navigation & Integration) is being initiated.
- Verify the change trigger and ensure you have the user's initial explanation of the issue and its perceived impact.
- Confirm access to all relevant project artifacts (e.g., PRD, Epics/Stories, Architecture Documents, UI/UX Specifications) and, critically, the `change-checklist` (e.g., `change-checklist`).
- **Establish Interaction Mode:**
- Ask the user their preferred interaction mode for this task:
- **"Incrementally (Default & Recommended):** Shall we work through the `change-checklist` section by section, discussing findings and collaboratively drafting proposed changes for each relevant part before moving to the next? This allows for detailed, step-by-step refinement."
- **"YOLO Mode (Batch Processing):** Or, would you prefer I conduct a more batched analysis based on the checklist and then present a consolidated set of findings and proposed changes for a broader review? This can be quicker for initial assessment but might require more extensive review of the combined proposals."
- Request the user to select their preferred mode.
- Once the user chooses, confirm the selected mode (e.g., "Okay, we will proceed in Incremental mode."). This chosen mode will govern how subsequent steps in this task are executed.
- **Explain Process:** Briefly inform the user: "We will now use the `change-checklist` to analyze the change and draft proposed updates. I will guide you through the checklist items based on our chosen interaction mode."
<rule>When asking multiple questions or presenting multiple points for user input at once, number them clearly (e.g., 1., 2a., 2b.) to make it easier for the user to provide specific responses.</rule>
### 2. Execute Checklist Analysis (Iteratively or Batched, per Interaction Mode)
- Systematically work through Sections 1-4 of the `change-checklist` (typically covering Change Context, Epic/Story Impact Analysis, Artifact Conflict Resolution, and Path Evaluation/Recommendation).
- For each checklist item or logical group of items (depending on interaction mode):
- Present the relevant prompt(s) or considerations from the checklist to the user.
- Request necessary information and actively analyze the relevant project artifacts (PRD, epics, architecture documents, story history, etc.) to assess the impact.
- Discuss your findings for each item with the user.
- Record the status of each checklist item (e.g., `[x] Addressed`, `[N/A]`, `[!] Further Action Needed`) and any pertinent notes or decisions.
- Collaboratively agree on the "Recommended Path Forward" as prompted by Section 4 of the checklist.
### 3. Draft Proposed Changes (Iteratively or Batched)
- Based on the completed checklist analysis (Sections 1-4) and the agreed "Recommended Path Forward" (excluding scenarios requiring fundamental replans that would necessitate immediate handoff to PM/Architect):
- Identify the specific project artifacts that require updates (e.g., specific epics, user stories, PRD sections, architecture document components, diagrams).
- **Draft the proposed changes directly and explicitly for each identified artifact.** Examples include:
- Revising user story text, acceptance criteria, or priority.
- Adding, removing, reordering, or splitting user stories within epics.
- Proposing modified architecture diagram snippets (e.g., providing an updated Mermaid diagram block or a clear textual description of the change to an existing diagram).
- Updating technology lists, configuration details, or specific sections within the PRD or architecture documents.
- Drafting new, small supporting artifacts if necessary (e.g., a brief addendum for a specific decision).
- If in "Incremental Mode," discuss and refine these proposed edits for each artifact or small group of related artifacts with the user as they are drafted.
- If in "YOLO Mode," compile all drafted edits for presentation in the next step.
### 4. Generate "Sprint Change Proposal" with Edits
- Synthesize the complete `change-checklist` analysis (covering findings from Sections 1-4) and all the agreed-upon proposed edits (from Instruction 3) into a single document titled "Sprint Change Proposal." This proposal should align with the structure suggested by Section 5 of the `change-checklist` (Proposal Components).
- The proposal must clearly present:
- **Analysis Summary:** A concise overview of the original issue, its analyzed impact (on epics, artifacts, MVP scope), and the rationale for the chosen path forward.
- **Specific Proposed Edits:** For each affected artifact, clearly show or describe the exact changes (e.g., "Change Story X.Y from: [old text] To: [new text]", "Add new Acceptance Criterion to Story A.B: [new AC]", "Update Section 3.2 of Architecture Document as follows: [new/modified text or diagram description]").
- Present the complete draft of the "Sprint Change Proposal" to the user for final review and feedback. Incorporate any final adjustments requested by the user.
### 5. Finalize & Determine Next Steps
- Obtain explicit user approval for the "Sprint Change Proposal," including all the specific edits documented within it.
- Provide the finalized "Sprint Change Proposal" document to the user.
- **Based on the nature of the approved changes:**
- **If the approved edits sufficiently address the change and can be implemented directly or organized by a PO/SM:** State that the "Correct Course Task" is complete regarding analysis and change proposal, and the user can now proceed with implementing or logging these changes (e.g., updating actual project documents, backlog items). Suggest handoff to a PO/SM agent for backlog organization if appropriate.
- **If the analysis and proposed path (as per checklist Section 4 and potentially Section 6) indicate that the change requires a more fundamental replan (e.g., significant scope change, major architectural rework):** Clearly state this conclusion. Advise the user that the next step involves engaging the primary PM or Architect agents, using the "Sprint Change Proposal" as critical input and context for that deeper replanning effort.
## Output Deliverables
- **Primary:** A "Sprint Change Proposal" document (in markdown format). This document will contain:
- A summary of the `change-checklist` analysis (issue, impact, rationale for the chosen path).
- Specific, clearly drafted proposed edits for all affected project artifacts.
- **Implicit:** An annotated `change-checklist` (or the record of its completion) reflecting the discussions, findings, and decisions made during the process.

# Create AI Frontend Prompt Task
## Purpose
To generate a masterful, comprehensive, and optimized prompt that can be used with AI-driven frontend development tools (e.g., Lovable, Vercel v0, or similar) to scaffold or generate significant portions of the frontend application.
## Inputs
- Completed UI/UX Specification (`front-end-spec-tmpl`)
- Completed Frontend Architecture Document (`front-end-architecture`)
- Main System Architecture Document (`architecture` - for API contracts and tech stack)
- Primary Design Files (Figma, Sketch, etc. - for visual context if the tool can accept it or if descriptions are needed)
## Key Activities & Instructions
1. **Confirm Target AI Generation Platform:**
- Ask the user to specify which AI frontend generation tool/platform they intend to use (e.g., "Lovable.ai", "Vercel v0", "GPT-4 with direct code generation instructions", etc.).
- Explain that prompt optimization might differ slightly based on the platform's capabilities and preferred input format.
2. **Synthesize Inputs into a Structured Prompt:**
- **Overall Project Context:**
- Briefly state the project's purpose (from brief/PRD).
- Specify the chosen frontend framework, core libraries, and UI component library (from `front-end-architecture` and main `architecture`).
- Mention the styling approach (e.g., Tailwind CSS, CSS Modules).
- **Design System & Visuals:**
- Reference the primary design files (e.g., Figma link).
- If the tool doesn't directly ingest design files, describe the overall visual style, color palette, typography, and key branding elements (from `front-end-spec-tmpl`).
- List any global UI components or design tokens that should be defined or adhered to.
- **Application Structure & Routing:**
- Describe the main pages/views and their routes (from `front-end-architecture` - Routing Strategy).
- Outline the navigation structure (from `front-end-spec-tmpl`).
- **Key User Flows & Page-Level Interactions:**
- For a few critical user flows (from `front-end-spec-tmpl`):
- Describe the sequence of user actions and expected UI changes on each relevant page.
- Specify API calls to be made (referencing API endpoints from the main `architecture`) and how data should be displayed or used.
- **Component Generation Instructions (Iterative or Key Components):**
- Based on the chosen AI tool's capabilities, decide on a strategy:
- **Option 1 (Scaffolding):** Prompt for the generation of main page structures, layouts, and placeholders for components.
- **Option 2 (Key Component Generation):** Select a few critical or complex components from the `front-end-architecture` (Component Breakdown) and provide detailed specifications for them (props, state, basic behavior, key UI elements).
- **Option 3 (Holistic, if tool supports):** Attempt to describe the entire application structure and key components more broadly.
- <important_note>Advise the user that generating an entire complex application perfectly in one go is rare. Iterative prompting or focusing on sections/key components is often more effective.</important_note>
- **State Management (High-Level Pointers):**
- Mention the chosen state management solution (e.g., "Use Redux Toolkit").
- For key pieces of data, indicate if they should be managed in global state.
- **API Integration Points:**
- For pages/components that fetch or submit data, clearly state the relevant API endpoints (from `architecture`) and the expected data shapes (can reference schemas in `data-models` or `api-reference` sections of the architecture doc).
- **Critical "Don'ts" or Constraints:**
- e.g., "Do not use deprecated libraries." "Ensure all forms have basic client-side validation."
- **Platform-Specific Optimizations:**
- If the chosen AI tool has known best practices for prompting (e.g., specific keywords, structure, level of detail), incorporate them. (This might require the agent to have some general knowledge or to ask the user if they know any such specific prompt modifiers for their chosen tool).
3. **Present and Refine the Master Prompt:**
- Output the generated prompt in a clear, copy-pasteable format (e.g., a large code block).
- Explain the structure of the prompt and why certain information was included.

# Architecture Creation Task
## Purpose
- To design a complete, robust, and well-documented technical architecture based on the project requirements (PRD, epics, brief), research findings, and user input.
- To make definitive technology choices and articulate the rationale behind them, leveraging the architecture template as a structural guide.
- To produce all necessary technical artifacts, ensuring the architecture is optimized for efficient implementation, particularly by AI developer agents, and validated against the `architect-checklist`.
## Instructions
1. **Input Analysis & Dialogue Establishment:**
- Ensure you have all necessary inputs: PRD document (specifically checking for the 'Technical Assumptions' and 'Initial Architect Prompt' sections for the decided repository and service architecture), project brief, any deep research reports, and optionally a `technical-preferences.md`. Request any missing critical documents.
- Thoroughly review all inputs.
- Summarize key technical requirements, constraints, NFRs (Non-Functional Requirements), and the decided repository/service architecture derived from the inputs. Present this summary to the user for confirmation and to ensure mutual understanding.
- Share initial architectural observations, potential challenges, or areas needing clarification based on the inputs.
**Establish Interaction Mode for Architecture Creation:**
- Ask the user: "How would you like to proceed with creating the architecture for this project? We can work:
A. **Incrementally (Default & Recommended):** We'll go through each architectural decision, document section, or design point step-by-step. I'll present drafts, and we'll seek your feedback and confirmation before moving to the next part. This is best for complex decisions and detailed refinement.
B. **"YOLO" Mode:** I can produce a more comprehensive initial draft of the architecture (or significant portions) for you to review more broadly first. We can then iterate on specific sections based on your feedback. This can be quicker for generating initial ideas but is generally not recommended if detailed collaboration at each step is preferred."
- Request the user to select their preferred mode (e.g., "Please let me know if you'd prefer A or B.").
- Once the user chooses, confirm the selected mode (e.g., "Okay, we will proceed in Incremental mode."). This chosen mode will govern how subsequent steps in this task are executed.
2. **Resolve Ambiguities & Gather Missing Information:**
- If key information is missing or requirements are unclear after initial review, formulate specific, targeted questions.
- **External API Details:** If the project involves integration with external APIs, especially those that are less common or where you lack high confidence in your training data regarding their specific request/response schemas, and if a "Deep Research" phase was not conducted for these APIs:
- Proactively ask the user to provide precise details. This includes:
- Links to the official API documentation.
- Example request structures (e.g., cURL commands, JSON payloads).
- Example response structures (e.g., JSON responses for typical scenarios, including error responses).
- Explain that this information is crucial for accurately defining API interaction contracts within the architecture, for creating robust facades/adapters, and for enabling accurate technical planning (e.g., for technical stories or epic refinements).
- Present questions to the user (batched logically if multiple) and await their input.
- Document all decisions and clarifications received before proceeding.
3. **Iterative Technology Selection & Design (Interactive, if not YOLO mode):**
- For each major architectural component or decision point (e.g., frontend framework, backend language/framework, database system, cloud provider, key services, communication patterns):
- If multiple viable options exist based on requirements or research, present 2-3 choices, briefly outlining their pros, cons, and relevance to the project. Consider any preferences stated in `technical-preferences.md` when formulating these options and your recommendation.
- State your recommended choice, providing a clear rationale based on requirements, research findings, user preferences (if known), and best practices (e.g., scalability, cost, team familiarity, ecosystem).
- Ask for user feedback, address concerns, and seek explicit approval before finalizing the decision.
- Document the confirmed choice and its rationale within the architecture document.
- **Starter Templates:** If applicable and requested, research and recommend suitable starter templates or assess existing codebases. Explain alignment with project goals and seek user confirmation.
4. **Create Technical Artifacts (Incrementally, unless YOLO mode, guided by `architecture-tmpl`):**
- For each artifact or section of the main Architecture Document:
- **Explain Purpose:** Briefly describe the artifact/section's importance and what it will cover.
- **Draft Section-by-Section:** Present a draft of one logical section at a time.
- Ensure the 'High-Level Overview' and 'Component View' sections accurately reflect and detail the repository/service architecture decided in the PRD.
- Ensure that documented Coding Standards (either as a dedicated section or referenced) and the 'Testing Strategy' section clearly define:
- The convention for unit test file location (e.g., co-located with source files, or in a separate folder like `tests/` or `__tests__/`).
- The naming convention for unit test files (e.g., `*.test.js`, `*.spec.ts`, `test_*.py`).
- When discussing Coding Standards, inform the user that these will serve as firm rules for the AI developer agent. Emphasize that these standards should be kept to the minimum necessary to prevent undesirable or messy code from the agent. Guide the user to understand that overly prescriptive or obvious standards (e.g., "use SOLID principles," which well-trained LLMs should already know) should be avoided, as the user, knowing the specific agents and tools they will employ, can best judge the appropriate level of detail.
- **Incorporate Feedback:** Discuss the draft with the user, incorporate their feedback, and iterate as needed.
- [Offer Advanced Self-Refinement & Elicitation Options](#offer-advanced-self-refinement--elicitation-options)
- **Seek Approval:** Obtain explicit user approval for the section before moving to the next, or for the entire artifact if drafted holistically (in YOLO mode).
5. **Identify Missing Technical Stories / Refine Epics (Interactive):**
- Based on the designed architecture, identify any necessary technical stories/tasks that are not yet captured in the PRD or epics (e.g., "Set up CI/CD pipeline for frontend deployment," "Implement authentication module using JWT," "Create base Docker images for backend services," "Configure initial database schema based on data models").
- Explain the importance of these technical stories for enabling the functional requirements and successful project execution.
- Collaborate with the user to refine these stories (clear description, acceptance criteria) and suggest adding them to the project backlog or relevant epics.
- Review existing epics/stories from the PRD and suggest technical considerations or acceptance criteria refinements to ensure they are implementable based on the chosen architecture. For example, specifying API endpoints to be called, data formats, or critical library versions.
- After collaboration, prepare a concise summary detailing all proposed additions, updates, or modifications to epics and user stories. If no changes are identified, explicitly state this.
6. **Validate Architecture Against Checklist & Finalize Output:**
- Once the main architecture document components have been drafted and reviewed with the user, perform a comprehensive review using the `architect-checklist`.
- Go through each item in the checklist to ensure the architecture document is comprehensive, addresses all key architectural concerns (e.g., security, scalability, maintainability, testability (including confirmation that coding standards and the testing strategy clearly define unit test location and naming conventions), developer experience), and that proposed solutions are robust.
- For each checklist item, confirm its status (e.g., \[x] Completed, \[ ] N/A, \[!] Needs Attention).
- If deficiencies, gaps, or areas needing more detail or clarification are identified based on the checklist:
- Discuss these findings with the user.
- Collaboratively make necessary updates, additions, or refinements to the architecture document to address these points.
- After addressing all checklist points and ensuring the architecture document is robust and complete, present a summary of the checklist review to the user. This summary should highlight:
- Confirmation that all relevant sections/items of the checklist have been satisfied by the architecture.
- Any items marked N/A, with a brief justification.
- A brief note on any significant discussions, decisions, or changes made to the architecture document as a result of the checklist review.
- **Offer Design Architect Prompt (If Applicable):**
- If the architecture includes UI components, ask the user if they would like to include a dedicated prompt for a "Design Architect" at the end of the main architecture document.
- Explain that this prompt can capture specific UI considerations, notes from discussions, or decisions that don't fit into the core technical architecture document but are crucial for the Design Architect.
- The prompt should also state that the Design Architect will subsequently operate in its specialized mode to define the detailed frontend architecture.
- If the user agrees, collaboratively draft this prompt and append it to the architecture document.
- Obtain final user approval for the complete architecture documentation generation.
- **Recommend Next Steps for UI (If Applicable):**
- After the main architecture document is finalized and approved:
- If the project involves a user interface (as should be evident from the input PRD and potentially the architecture document itself mentioning UI components or referencing outputs from a Design Architect's UI/UX Specification phase):
- Strongly recommend to the user that the next critical step for the UI is to engage the **Design Architect** agent.
- Specifically, advise them to use the Design Architect's **'Frontend Architecture Mode'**.
- Explain that the Design Architect will use the now-completed main Architecture Document and the detailed UI/UX specifications (e.g., `front-end-spec-tmpl.txt` or enriched PRD) as primary inputs to define the specific frontend architecture, select frontend libraries/frameworks (if not already decided), structure frontend components, and detail interaction patterns.
### Output Deliverables for Architecture Creation Phase
- A comprehensive Architecture Document, structured according to the `architecture-tmpl` (which is all markdown) or an agreed-upon format, including all sections detailed above.
- Clear Mermaid diagrams for architecture overview, data models, etc.
- A list of new or refined technical user stories/tasks ready for backlog integration.
- A summary of any identified changes (additions, updates, modifications) required for existing epics or user stories, or an explicit confirmation if no such changes are needed.
- A completed `architect-checklist` (or a summary of its validation).
- Optionally, if UI components are involved and the user agrees: A prompt for a "Design Architect" appended to the main architecture document, summarizing relevant UI considerations and outlining the Design Architect's next steps.
## Offer Advanced Self-Refinement & Elicitation Options
(This section is called when needed prior to this)
Present the user with the following list of 'Advanced Reflective, Elicitation & Brainstorming Actions'. Explain that these are optional steps to help ensure quality, explore alternatives, and deepen the understanding of the current section before finalizing it and moving on. The user can select an action by number, or choose to skip this and proceed to finalize the section.
"To ensure the quality of the current section: **[Specific Section Name]** and to ensure its robustness, explore alternatives, and consider all angles, I can perform any of the following actions. Please choose a number (8 to finalize and proceed):
**Advanced Reflective, Elicitation & Brainstorming Actions I Can Take:**
{Instruction for AI Agent: Display the title of each numbered item below. If the user asks what a specific option means, provide a brief explanation of the action you will take, drawing from detailed descriptions tailored for the context.}

# Deep Research Phase
Leveraging advanced analytical capabilities, the Deep Research Phase with the PM is designed to provide targeted, strategic insights crucial for product definition. Unlike the broader exploratory research an Analyst might undertake, the PM utilizes deep research to:
- **Validate Product Hypotheses:** Rigorously test assumptions about market need, user problems, and the viability of specific product concepts.
- **Refine Target Audience & Value Proposition:** Gain a nuanced understanding of specific user segments, their precise pain points, and how the proposed product delivers unique value to them.
- **Focused Competitive Analysis:** Analyze competitors through the lens of a specific product idea to identify differentiation opportunities, feature gaps to exploit, and potential market positioning challenges.
- **De-risk PRD Commitments:** Ensure that the problem, proposed solution, and core features are well-understood and validated _before_ detailed planning and resource allocation in the PRD Generation Mode.
Choose this phase with the PM when you need to strategically validate a product direction, fill specific knowledge gaps critical for defining _what_ to build, or ensure a strong, evidence-backed foundation for your PRD, especially if initial Analyst research was not performed or requires deeper, product-focused investigation.
## Purpose
- To gather foundational information, validate concepts, understand market needs, or analyze competitors when a comprehensive Project Brief from an Analyst is unavailable or insufficient.
- To ensure the PM has a solid, data-informed basis for defining a valuable and viable product before committing to PRD specifics.
- To de-risk product decisions by grounding them in targeted research, especially if the user is engaging the PM directly without prior Analyst work or if the initial brief lacks necessary depth.
## Instructions
<critical_rule>Note on Deep Research Execution:</critical_rule>
To perform deep research effectively, please be aware:
- You may need to use this current conversational agent to help you formulate a comprehensive research prompt, which can then be executed by a dedicated deep research model or function.
- Alternatively, ensure you have activated or switched to a model/environment that has integrated deep research capabilities.
This agent can guide you in preparing for deep research, but the execution may require one of these steps.
1. **Assess Inputs & Identify Gaps:**
- Review any existing inputs (user's initial idea, high-level requirements, partial brief from Analyst, etc.).
- Clearly identify critical knowledge gaps concerning:
- Target audience (needs, pain points, behaviors, key segments).
- Market landscape (size, trends, opportunities, potential saturation).
- Competitive analysis (key direct/indirect competitors, their offerings, strengths, weaknesses, market positioning, potential differentiators for this product).
- Problem/Solution validation (evidence supporting the proposed solution's value and fit for the identified problem).
- High-level technical or resource considerations (potential major roadblocks or dependencies).
2. **Formulate Research Plan:**
- Define specific, actionable research questions to address the identified gaps.
- Propose targeted research activities (e.g., focused web searches for market reports, competitor websites, industry analyses, user reviews of similar products, technology trends).
- <important_note>Confirm this research plan, scope, and key questions with the user before proceeding with research execution.</important_note>
3. **Execute Research:**
- Conduct the planned research activities systematically.
- Prioritize gathering credible, relevant, and actionable insights that directly inform product definition and strategy.
4. **Synthesize & Present Findings:**
- Organize and summarize key research findings in a clear, concise, and easily digestible manner (e.g., bullet points, brief summaries per research question).
- Highlight the most critical implications for the product's vision, strategy, target audience, core features, and potential risks.
- Present these synthesized findings and their implications to the user.
5. **Discussing and Utilizing Research Output:**
- The comprehensive findings/report from this Deep Research phase can be substantial. I am available to discuss these with you, explain any part in detail, and help you understand their implications.
- **Options for Utilizing These Findings for PRD Generation:**
1. **Full Handoff to New PM Session:** The complete research output can serve as a foundational document if you initiate a _new_ session with a Product Manager (PM) agent who will then execute the 'PRD Generate Task'.
2. **Key Insights Summary for This Session:** I can prepare a concise summary of the most critical findings, tailored to be directly actionable as we (in this current session) transition to potentially invoking the 'PRD Generate Task'.
- <critical_rule>Regardless of how you proceed, it is highly recommended that these research findings (either the full output or the key insights summary) are provided as direct input when invoking the 'PRD Generate Task'. This ensures the PRD is built upon a solid, evidence-based foundation.</critical_rule>
6. **Confirm Readiness for PRD Generation:**
- Discuss with the user whether the gathered information provides a sufficient and confident foundation to proceed to the 'PRD Generate Task'.
- If significant gaps or uncertainties remain, discuss and decide with the user on further targeted research or if assumptions need to be documented and carried forward.
- Once confirmed, clearly state that the next step could be to invoke the 'PRD Generate Task' or, if applicable, revisit other phase options.

# Create Document from Template Task
## Purpose
- Generate documents from any specified template following embedded instructions
- Support multiple document types through template-driven approach
- Enable any persona to create consistent, well-structured documents
## Instructions
### 1. Identify Template and Context
- Determine which template to use (user-provided or list available for selection to user)
- agent-config specific agents will list what docs they have available under this task, for each item consider it a unique task. So if the user had for example:
@{example}
- tasks:
- [Create Document](tasks#create-doc-from-template):
- [Prd](templates#prd-tmpl)
- [Architecture](templates#architecture-tmpl)
@{/example}
you would list `Create Document PRD` and `Create Document Architecture` as tasks the agent could perform.
- Gather all relevant inputs, or ask for them, or else rely on user providing necessary details to complete the document
- Understand the document purpose and target audience
### 2. Determine Interaction Mode
Confirm with the user their preferred interaction style:
- **Incremental:** Work through chunks of the document.
- **YOLO Mode:** Draft complete document making reasonable assumptions in one shot. (Can be entered also after starting incremental by just typing /yolo)
### 3. Execute Template
- Load specified template from `templates#*` or the /templates directory
- Follow ALL embedded LLM instructions within the template
- Process template markup according to `templates#template-format` conventions
### 4. Template Processing Rules
**CRITICAL: Never display template markup, LLM instructions, or examples to users**
- Replace all {{placeholders}} with actual content
- Execute all [[LLM: instructions]] internally
- Process <<REPEAT>> sections as needed
- Evaluate ^^CONDITION^^ blocks and include only if applicable
- Use @{examples} for guidance but never output them
### 5. Content Generation
- **Incremental Mode**: Present each major section for review before proceeding
- **YOLO Mode**: Generate all sections, then review complete document with user
- Apply any elicitation protocols specified in template
- Incorporate user feedback and iterate as needed
### 6. Validation
If template specifies a checklist:
- Run the appropriate checklist against completed document
- Document completion status for each item
- Address any deficiencies found
- Present validation summary to user
### 7. Final Presentation
- Present clean, formatted content only
- Ensure all sections are complete
- DO NOT truncate or summarize content
- Begin directly with document content (no preamble)
- Include any handoff prompts specified in template
## Key Resources
- **Template Format:** `templates#template-format`
- **Available Templates:** All files in `templates#` directory
- **Checklists:** As specified by template or persona
- **User Preferences:** `data#technical-preferences`
## Important Notes
- This task is template and persona agnostic

# Create Frontend Architecture Task
## Purpose
To define the technical architecture for the frontend application. This includes selecting appropriate patterns, structuring the codebase, defining component strategy, planning state management, outlining API interactions, and setting up testing and deployment approaches, all while adhering to the guidelines in `front-end-architecture-tmpl` template.
## Inputs
- Product Requirements Document (PRD) (`prd-tmpl` or equivalent)
- Completed UI/UX Specification (`front-end-spec-tmpl` or equivalent)
- Main System Architecture Document (`architecture` or equivalent) - The agent executing this task should particularly note the overall system structure (Monorepo/Polyrepo, backend service architecture) detailed here, as it influences frontend patterns.
- Primary Design Files (Figma, Sketch, etc., linked from UI/UX Spec)
## Key Activities & Instructions
### 1. Confirm Interaction Mode
- Ask the user: "How would you like to proceed with creating the frontend architecture? We can work:
A. **Incrementally (Default & Recommended):** We'll go through each architectural decision and document section step-by-step. I'll present drafts, and we'll seek your feedback and confirmation before moving to the next part. This is best for complex decisions and detailed refinement.
B. **"YOLO" Mode:** I can produce a more comprehensive initial draft of the frontend architecture for you to review more broadly first. We can then iterate on specific sections based on your feedback. This can be quicker for generating initial ideas but is generally not recommended if detailed collaboration at each step is preferred."
- Request the user to select their preferred mode (e.g., "Please let me know if you'd prefer A or B.").
- Once the user chooses, confirm the selected mode (e.g., "Okay, we will proceed in Incremental mode."). This chosen mode will govern how subsequent steps are executed.
### 2. Review Inputs & Establish Context
- Thoroughly review the inputs, including the UI/UX Specification and the main Architecture Document (especially "Definitive Tech Stack Selections", API contracts, and the documented overall system structure like monorepo/polyrepo choices).
- Ask clarifying questions to bridge any gaps between the UI/UX vision and the overall system architecture.
### 3. Define Overall Frontend Philosophy & Patterns (for `front-end-architecture`)
- Based on the main architecture's tech stack and overall system structure (monorepo/polyrepo, backend service details), confirm and detail:
- Framework & Core Libraries choices.
- High-level Component Architecture strategy.
- High-level State Management Strategy.
- Data Flow principles.
- Styling Approach.
- Key Design Patterns to be employed.
### 4. Specify Detailed Frontend Directory Structure (for `front-end-architecture`)
- Collaboratively define or refine the frontend-specific directory structure, ensuring it aligns with the chosen framework and promotes modularity and scalability.
### 5. Outline Component Strategy & Conventions (for `front-end-architecture`)
- Define Component Naming & Organization conventions.
- Establish the "Template for Component Specification" (as per `front-end-architecture`), emphasizing that most components will be detailed emergently but must follow this template.
- Optionally, specify a few absolutely foundational/shared UI components (e.g., a generic Button or Modal wrapper if the chosen UI library needs one, or if no UI library is used).
### 6. Detail State Management Setup & Conventions (for `front-end-architecture`)
- Based on the high-level strategy, detail:
- Chosen Solution and core setup.
- Conventions for Store Structure / Slices (e.g., "feature-based slices"). Define any genuinely global/core slices (e.g., session/auth).
- Conventions for Selectors and Actions/Reducers/Thunks. Provide templates or examples.
### 7. Plan API Interaction Layer (for `front-end-architecture`)
- Define the HTTP Client Setup.
- Establish patterns for Service Definitions (how API calls will be encapsulated).
- Outline frontend Error Handling & Retry strategies for API calls.
### 8. Define Routing Strategy (for `front-end-architecture`)
- Confirm the Routing Library.
- Collaboratively define the main Route Definitions and any Route Guards.
### 9. Specify Build, Bundling, and Deployment Details (for `front-end-architecture`)
- Outline the frontend-specific Build Process & Scripts.
- Discuss and document Key Bundling Optimizations.
- Confirm Deployment to CDN/Hosting details relevant to the frontend.
### 10. Refine Frontend Testing Strategy (for `front-end-architecture`)
- Elaborate on the main testing strategy with specifics for: Component Testing, UI Integration/Flow Testing, and E2E UI Testing scope and tools.
### 11. Outline Performance Considerations (for `front-end-architecture`)
- List key frontend-specific performance strategies to be employed.
### 12. Document Drafting & Confirmation (Guided by `front-end-architecture-tmpl`)
- **If "Incremental Mode" was selected:**
- For each relevant section of the `front-end-architecture` (as outlined in steps 3-11 above, covering topics from Overall Philosophy to Performance Considerations):
- **a. Explain Purpose & Draft Section:** Explain the purpose of the section and present a draft for that section.
- **b. Initial Discussion & Feedback:** Discuss the draft with the user, incorporate their feedback, and iterate as needed for initial revisions.
- **c. [Offer Advanced Self-Refinement & Elicitation Options](#offer-advanced-self-refinement--elicitation-options)**
- **d. Final Approval & Documentation:** Obtain explicit user approval for the section. Ensure all placeholder links and references are correctly noted within each section. Then proceed to the next section.
- Once all sections are individually approved through this process, confirm with the user that the overall `front-end-architecture` document is populated and ready for Step 13 (Epic/Story Impacts) and then the checklist review (Step 14).
- **If "YOLO Mode" was selected:**
- Collaboratively populate all relevant sections of the `front-end-architecture-tmpl` (as outlined in steps 3-11 above) to create a comprehensive first draft.
- Present the complete draft of `front-end-architecture` to the user for a holistic review.
- <important_note>After presenting the full draft in YOLO mode, you MAY still offer a condensed version of the 'Advanced Reflective & Elicitation Options' menu, perhaps focused on a few key overarching review actions (e.g., overall requirements alignment, major risk assessment) if the user wishes to perform a structured deep dive before detailed section-by-section feedback.</important_note>
- Obtain explicit user approval for the entire `front-end-architecture` document before proceeding to Step 13 (Epic/Story Impacts) and then the checklist review (Step 14).
### 13. Identify & Summarize Epic/Story Impacts (Frontend Focus)
- After the `front-end-architecture` is confirmed, review it in context of existing epics and user stories (if provided or known).
- Identify any frontend-specific technical tasks that might need to be added as new stories or sub-tasks (e.g., "Implement responsive layout for product details page based on defined breakpoints," "Set up X state management slice for user profile," "Develop reusable Y component as per specification").
- Identify if any existing user stories require refinement of their acceptance criteria due to frontend architectural decisions (e.g., specifying interaction details, component usage, or performance considerations for UI elements).
- Collaborate with the user to define these additions or refinements.
- Prepare a concise summary detailing all proposed additions, updates, or modifications to epics and user stories related to the frontend. If no changes are identified, explicitly state this (e.g., "No direct impacts on existing epics/stories were identified from the frontend architecture").
### 14. Checklist Review and Finalization
- Once the `front-end-architecture` has been populated and reviewed with the user, and epic/story impacts have been summarized, use the `frontend-architecture-checklist`.
- Go through each item in the checklist to ensure the `front-end-architecture` is comprehensive and all sections are adequately addressed - for each checklist item you MUST consider if it is really complete or deficient.
- For each checklist section, confirm its status (e.g., \[x] Completed, \[ ] N/A, \[!] Needs Attention).
- If deficiencies or areas needing more detail are identified with a section:
- Discuss these with the user.
- Collaboratively make necessary updates or additions to the `front-end-architecture`.
- After addressing all points and ensuring the document is robust, present a summary of the checklist review to the user. This summary should highlight:
- Confirmation that all relevant sections of the checklist have been satisfied.
- Any items marked N/A and a brief reason.
- A brief note on any significant discussions or changes made as a result of the checklist review.
- The goal is to ensure the `front-end-architecture` is a complete and actionable document.

# Create Next Story Task
## Purpose
To identify the next logical story based on project progress and epic definitions, and then to prepare a comprehensive, self-contained, and actionable story file using the `Story Template`. This task ensures the story is enriched with all necessary technical context, requirements, and acceptance criteria, making it ready for efficient implementation by a Developer Agent with minimal need for additional research.
## Inputs for this Task
- Access to the project's documentation repository, specifically:
- `docs/index.md` (hereafter "Index Doc")
- All Epic files (e.g., `docs/epic-{n}.md` - hereafter "Epic Files")
- Existing story files in `docs/stories/`
- Main PRD (hereafter "PRD Doc")
- Main Architecture Document (hereafter "Main Arch Doc")
- Frontend Architecture Document (hereafter "Frontend Arch Doc," if relevant)
- Project Structure Guide (`docs/project-structure.md`)
- Operational Guidelines Document (`docs/operational-guidelines.md`)
- Technology Stack Document (`docs/tech-stack.md`)
- Data Models Document (as referenced in Index Doc)
- API Reference Document (as referenced in Index Doc)
- UI/UX Specifications, Style Guides, Component Guides (if relevant, as referenced in Index Doc)
- The `bmad-agent/templates/story-tmpl.md` (hereafter "Story Template")
- The `bmad-agent/checklists/story-draft-checklist.md` (hereafter "Story Draft Checklist")
- User confirmation to proceed with story identification and, if needed, to override warnings about incomplete prerequisite stories.
## Task Execution Instructions
### 1. Identify Next Story for Preparation
- Review `docs/stories/` to find the highest-numbered story file.
- **If a highest story file exists (`{lastEpicNum}.{lastStoryNum}.story.md`):**
- Verify its `Status` is 'Done' (or equivalent).
- If not 'Done', present an alert to the user:
```plaintext
ALERT: Found incomplete story:
File: {lastEpicNum}.{lastStoryNum}.story.md
Status: [current status]
Would you like to:
1. View the incomplete story details (instructs user to do so, agent does not display)
2. Cancel new story creation at this time
3. Accept risk & Override to create the next story in draft
Please choose an option (1/2/3):
```
- Proceed only if user selects option 3 (Override) or if the last story was 'Done'.
- If proceeding: Check the Epic File for `{lastEpicNum}` for a story numbered `{lastStoryNum + 1}`. If it exists and its prerequisites (per Epic File) are met, this is the next story.
- Else (story not found or prerequisites not met): The next story is the first story in the next Epic File (e.g., `docs/epic-{lastEpicNum + 1}.md`, then `{lastEpicNum + 2}.md`, etc.) whose prerequisites are met.
- **If no story files exist in `docs/stories/`:**
- The next story is the first story in `docs/epic-1.md` (then `docs/epic-2.md`, etc.) whose prerequisites are met.
- If no suitable story with met prerequisites is found, report to the user that story creation is blocked, specifying what prerequisites are pending. HALT task.
- Announce the identified story to the user: "Identified next story for preparation: {epicNum}.{storyNum} - {Story Title}".
### 2. Gather Core Story Requirements (from Epic File)
- For the identified story, open its parent Epic File.
- Extract: Exact Title, full Goal/User Story statement, initial list of Requirements, all Acceptance Criteria (ACs), and any predefined high-level Tasks.
- Keep a record of this original epic-defined scope for later deviation analysis.
### 3. Gather & Synthesize In-Depth Technical Context for Dev Agent
- <critical_rule>Systematically use the Index Doc (`docs/index.md`) as your primary guide to discover paths to ALL detailed documentation relevant to the current story's implementation needs.</critical_rule>
- Thoroughly review the PRD Doc, Main Arch Doc, and Frontend Arch Doc (if a UI story).
- Guided by the Index Doc and the story's needs, locate, analyze, and synthesize specific, relevant information from sources such as:
- Data Models Doc (structure, validation rules).
- API Reference Doc (endpoints, request/response schemas, auth).
- Applicable architectural patterns or component designs from Arch Docs.
- UI/UX Specs, Style Guides, Component Guides (for UI stories).
- Specifics from Tech Stack Doc if versions or configurations are key for this story.
- Relevant sections of the Operational Guidelines Doc (e.g., story-specific error handling nuances, security considerations for data handled in this story).
- The goal is to collect all necessary details the Dev Agent would need, to avoid them having to search extensively. Note any discrepancies between the epic and these details for "Deviation Analysis."
### 4. Verify Project Structure Alignment
- Cross-reference the story's requirements and anticipated file manipulations with the Project Structure Guide (and frontend structure if applicable).
- Ensure any file paths, component locations, or module names implied by the story align with defined structures.
- Document any structural conflicts, necessary clarifications, or undefined components/paths in a "Project Structure Notes" section within the story draft.
### 5. Populate Story Template with Full Context
- Create a new story file: `docs/stories/{epicNum}.{storyNum}.story.md`.
- Use the Story Template to structure the file.
- Fill in:
- Story `{EpicNum}.{StoryNum}: {Short Title Copied from Epic File}`
- `Status: Draft`
- `Story` (User Story statement from Epic)
- `Acceptance Criteria (ACs)` (from Epic, to be refined if needed based on context)
- **`Dev Technical Guidance` section (CRITICAL):**
- Based on all context gathered (Step 3 & 4), embed concise but critical snippets of information, specific data structures, API endpoint details, precise references to _specific sections_ in other documents (e.g., "See `Data Models Doc#User-Schema-ValidationRules` for details"), or brief explanations of how architectural patterns apply to _this story_.
- If UI story, provide specific references to Component/Style Guides relevant to _this story's elements_.
- The aim is to make this section the Dev Agent's primary source for _story-specific_ technical context.
- **`Tasks / Subtasks` section:**
- Generate a detailed, sequential list of technical tasks and subtasks the Dev Agent must perform to complete the story, informed by the gathered context.
- Link tasks to ACs where applicable (e.g., `Task 1 (AC: 1, 3)`).
- Add notes on project structure alignment or discrepancies found in Step 4.
- Prepare content for the "Deviation Analysis" based on discrepancies noted in Step 3.

- All markdown (`.md`) and text (`.txt`) files in the documentation structure
2. For the existing `docs/index.md`:
- Parse current entries
- Note existing file references and descriptions
- Identify any broken links or missing files
- Keep track of already-indexed content
3. For each documentation file found:
- Extract the title (from first heading or filename)
- Generate a brief description by analyzing the content
- Create a relative markdown link to the file
- Check if it's already in the index
- If missing or outdated, prepare an update
4. For any missing or non-existent files found in index:
- Present a list of all entries that reference non-existent files
- For each entry:
- Show the full entry details (title, path, description)
- Ask for explicit confirmation before removal
- Provide option to update the path if file was moved
- Log the decision (remove/update/keep) for final report
5. Update `docs/index.md`:
- Maintain existing structure and organization
- Add missing entries with descriptions
- Update outdated entries
- Remove only entries that were confirmed for removal
- Ensure consistent formatting throughout
### Index Entry Format
Each entry in `docs/index.md` should follow this format:
```markdown
### [Document Title](relative/path/to/file.md)
Brief description of the document's purpose and contents.
```
### Rules of Operation
1. NEVER modify the content of indexed files
2. Preserve existing descriptions in index.md when they are adequate
3. Maintain any existing categorization or grouping in the index
4. Use relative paths for all links
5. Ensure descriptions are concise but informative
6. NEVER remove entries without explicit confirmation
7. Report any broken links or inconsistencies found
8. Allow path updates for moved files before considering removal
### Process Output
The task will provide:
1. A summary of changes made to index.md
2. List of newly indexed files
3. List of updated entries
4. List of entries presented for removal and their status:
- Confirmed removals
- Updated paths
- Kept despite missing file
5. Any other issues or inconsistencies found
### Handling Missing Files
For each file referenced in the index but not found in the filesystem:
1. Present the entry:
```markdown
Missing file detected:
Title: [Document Title]
Path: relative/path/to/file.md
Description: Existing description
Options:
1. Remove this entry
2. Update the file path
3. Keep entry (mark as temporarily unavailable)

# {Project Name} Architecture Document
## Introduction / Preamble
{This document outlines the overall project architecture, including backend systems, shared services, and non-UI specific concerns. Its primary goal is to serve as the guiding architectural blueprint for AI-driven development, ensuring consistency and adherence to chosen patterns and technologies.
**Relationship to Frontend Architecture:**
If the project includes a significant user interface, a separate Frontend Architecture Document (typically named `front-end-architecture-tmpl.txt` or similar, and linked in the "Key Reference Documents" section) details the frontend-specific design and MUST be used in conjunction with this document. Core technology stack choices documented herein (see "Definitive Tech Stack Selections") are definitive for the entire project, including any frontend components.}
## Table of Contents
{ Update this if sections and subsections are added or removed }
## Technical Summary
{ Provide a brief paragraph overview of the system's architecture, key components, technology choices, and architectural patterns used. Reference the goals from the PRD. }
## High-Level Overview
{ Describe the main architectural style (e.g., Monolith, Microservices, Serverless, Event-Driven), reflecting the decision made in the PRD. Explain the repository structure (Monorepo/Polyrepo). Explain the primary user interaction or data flow at a conceptual level. }
{ Insert high-level mermaid system context or interaction diagram here - e.g., Mermaid Class C4 Models Layer 1 and 2 }
## Architectural / Design Patterns Adopted
{ List the key high-level patterns chosen for the architecture. These foundational patterns should be established early as they guide component design, interactions, and technology choices. }
- **Pattern 1:** {e.g., Serverless, Event-Driven, Microservices, CQRS} - _Rationale/Reference:_ {Briefly why, or link to a more detailed explanation if needed}
- **Pattern 2:** {e.g., Dependency Injection, Repository Pattern, Module Pattern} - _Rationale/Reference:_ {...}
- **Pattern N:** {...}
## Component View
{ Describe the major logical components or services of the system and their responsibilities, reflecting the decided overall architecture (e.g., distinct microservices, modules within a monolith, packages within a monorepo) and the architectural patterns adopted. Explain how they collaborate. }
- Component A: {Description of responsibility}
{Insert component diagram here if it helps - e.g., using Mermaid graph TD or C4 Model Container/Component Diagram}
- Component N...: {Description of responsibility}
{ Insert component diagram here if it helps - e.g., using Mermaid graph TD or C4 Model Container/Component Diagram }
## Project Structure
{Provide an ASCII or Mermaid diagram representing the project's folder structure. The following is a general example. If a `front-end-architecture-tmpl.txt` (or equivalent) is in use, it will contain the detailed structure for the frontend portion (e.g., within `src/frontend/` or a dedicated `frontend/` root directory). Shared code structure (e.g., in a `packages/` directory for a monorepo) should also be detailed here.}

(Adjust the example tree based on the actual project type - e.g., Python would have requirements.txt, etc. The structure above illustrates a potential separation for projects with distinct frontends; for simpler projects or APIs, the `src/` structure might be flatter.)
### Key Directory Descriptions
- docs/: Contains all project planning and reference documentation.
- infra/: Holds the Infrastructure as Code definitions (e.g., AWS CDK, Terraform).
- src/: Contains the main application source code. May be subdivided (e.g., `backend/`, `frontend/`, `shared/`) depending on project complexity and whether a separate frontend architecture document is in use.
- src/backend/core/ / src/core/ / src/domain/: Core business logic, entities, use cases, independent of frameworks/external services.
- src/backend/adapters/ / src/adapters/ / src/infrastructure/: Implementation details, interactions with databases, cloud SDKs, frameworks.
- src/backend/controllers/ / src/routes/ / src/pages/: Entry points for API requests or UI views (if UI is simple and not in a separate frontend structure).

);
```
_(Alternatively, use ORM model definitions, NoSQL document structure, etc.)_
## Core Workflow / Sequence Diagrams
{ Illustrate key or complex workflows using mermaid sequence diagrams. Can have high level tying the full project together, and also smaller epic level sequence diagrams. }
## Definitive Tech Stack Selections
{ This section outlines the definitive technology choices for the project. These selections should be made after a thorough understanding of the project's requirements, components, data models, and core workflows. The Architect Agent should guide the user through these decisions, ensuring each choice is justified and recorded accurately in the table below.
This table is the **single source of truth** for all technology selections. Other architecture documents (e.g., Frontend Architecture) must refer to these choices and elaborate on their specific application rather than re-defining them.
Key decisions to discuss and finalize here, which will then be expanded upon and formally documented in the detailed stack table below, include considerations such as:
- Preferred Starter Template Frontend: { Url to template or starter, if used }
- Preferred Starter Template Backend: { Url to template or starter, if used }
- Primary Language(s) & Version(s): {e.g., TypeScript 5.x, Python 3.11 - Specify exact versions, e.g., `5.2.3`}
- Primary Runtime(s) & Version(s): {e.g., Node.js 22.x - Specify exact versions, e.g., `22.0.1`}
Must be definitive selections; do not list open-ended choices (e.g., for web scraping, pick one tool, not two). Specify exact versions (e.g., `18.2.0`). If 'Latest' is used, it implies the latest stable version _at the time of this document's last update_, and the specific version (e.g., `xyz-library@2.3.4`) should be recorded. Pinning versions is strongly preferred to avoid unexpected breaking changes for the AI agent. }
| Category | Technology | Version / Details | Description / Purpose | Justification (Optional) |
| :------------------- | :---------------------- | :---------------- | :-------------------------------------- | :----------------------- |

## Infrastructure and Deployment Overview
- Cloud Provider(s): {e.g., AWS, Azure, GCP, On-premise}
- Core Services Used: {List key managed services - e.g., Lambda, S3, Kubernetes Engine, RDS, Kafka}
- Infrastructure as Code (IaC): {Tool used - e.g., AWS CDK, Terraform...} - Location: {Link to IaC code repo/directory}
- Deployment Strategy: {e.g., CI/CD pipeline with automated promotions, Blue/Green, Canary} - Tools: {e.g., Jenkins, GitHub Actions, GitLab CI}
- Environments: {List environments - e.g., Development, Staging, Production}
- Environment Promotion: {Describe steps, e.g., `dev` -\> `staging` (manual approval / automated tests pass) -\> `production` (automated after tests pass and optional manual approval)}
- Rollback Strategy: {e.g., Automated rollback on health check failure post-deployment, Manual trigger via CI/CD job, IaC state rollback. Specify primary mechanism.}
## Error Handling Strategy
- **General Approach:** {e.g., Use exceptions as primary mechanism, return error codes/tuples for specific modules, clearly defined custom error types hierarchy.}
- **Logging:**
- Library/Method: {e.g., `console.log/error` (Node.js), Python `logging` module with `structlog`, dedicated logging library like `Pino` or `Serilog`. Specify the chosen library.}
- Format: {e.g., JSON, plain text with timestamp and severity. JSON is preferred for structured logging.}
- Levels: {e.g., DEBUG, INFO, WARN, ERROR, CRITICAL. Specify standard usage for each.}
- Context: {What contextual information must be included? e.g., Correlation ID, User ID (if applicable and safe), Service Name, Operation Name, Key Parameters (sanitized).}
- **Specific Handling Patterns:**
- External API Calls: {Define retry mechanisms (e.g., exponential backoff, max retries - specify library if one is mandated like `Polly` or `tenacity`), circuit breaker pattern usage (e.g., using `resilience4j` or equivalent - specify if and how), timeout configurations (connect and read timeouts). How are API errors (4xx, 5xx) translated or propagated?}
- Internal Errors / Business Logic Exceptions: {How to convert internal errors to user-facing errors if applicable (e.g., generic error messages with a unique ID for support, specific error codes). Are there defined business exception classes?}
- Transaction Management: {Approach to ensure data consistency in case of errors during multi-step operations, e.g., database transactions (specify isolation levels if non-default), Saga pattern for distributed transactions (specify orchestrator/choreography and compensation logic).}
## Coding Standards
{These standards are mandatory for all code generation by AI agents and human developers. Deviations are not permitted unless explicitly approved and documented as an exception in this section or a linked addendum.}
- **Primary Runtime(s):** {e.g., Node.js 22.x, Python Runtime for Lambda - refer to Definitive Tech Stack}
- **Style Guide & Linter:** {e.g., ESLint with Airbnb config + Prettier; Black, Flake8, MyPy; Go fmt, golint. Specify chosen tools and link to configuration files (e.g., `.eslintrc.js`, `pyproject.toml`). Linter rules are mandatory and must not be disabled without cause.}
- **Naming Conventions:**
- Variables: `{e.g., camelCase (JavaScript/TypeScript/Java), snake_case (Python/Ruby)}`
- Functions/Methods: `{e.g., camelCase (JavaScript/TypeScript/Java), snake_case (Python/Ruby)}`
- Classes/Types/Interfaces: `{e.g., PascalCase}`
- Constants: `{e.g., UPPER_SNAKE_CASE}`
- Files: `{e.g., kebab-case.ts (TypeScript), snake_case.py (Python), PascalCase.java (Java). Be specific per language.}`
- Modules/Packages: `{e.g., camelCase or snake_case. Be specific per language.}`
- **File Structure:** Adhere to the layout defined in the "Project Structure" section and the Frontend Architecture Document if applicable.
- **Unit Test File Organization:** {e.g., `*.test.ts`/`*.spec.ts` co-located with source files; `test_*.py` in a parallel `tests/` directory. Specify chosen convention.}
- **Asynchronous Operations:** {e.g., Always use `async`/`await` in TypeScript/JavaScript/Python for promise-based operations; Goroutines/Channels in Go with clear patterns for error propagation and completion; Java `CompletableFuture` or Project Reactor/RxJava if used.}
- **Type Safety:** {e.g., Leverage TypeScript strict mode (all flags enabled); Python type hints (enforced by MyPy); Go static typing; Java generics and avoidance of raw types. All new code must be strictly typed.}
- _Type Definitions:_ {Location, e.g., `src/common/types.ts`, shared packages, or co-located. Policy on using `any` or equivalent (strongly discouraged, requires justification).}
- **Comments & Documentation:**
- Code Comments: {Expectations for code comments: Explain _why_, not _what_, for complex logic. Avoid redundant comments. Use standard formats like JSDoc, TSDoc, Python docstrings (Google/NumPy style), GoDoc, JavaDoc.}
- READMEs: {Each module/package/service should have a README explaining its purpose, setup, and usage if not trivial.}
- **Dependency Management:** {Tool used - e.g., npm/yarn, pip/poetry, Go modules, Maven/Gradle. Policy on adding new dependencies (e.g., approval process, check for existing alternatives, security vulnerability scans). Specify versioning strategy (e.g., prefer pinned versions, use tilde `~` for patches, caret `^` for minor updates - be specific).}
### Detailed Language & Framework Conventions
{For each primary language and framework selected in the "Definitive Tech Stack Selections", the following specific conventions **must** be adhered to. If a chosen technology is not listed below, it implies adherence to its standard, widely accepted best practices and the general guidelines in this document.}
#### `{Language/Framework 1 Name, e.g., TypeScript/Node.js}` Specifics:
- **Immutability:** `{e.g., "Always prefer immutable data structures. Use `Readonly\<T\>`, `ReadonlyArray\<T\>`, `as const` for object/array literals. Avoid direct mutation of objects/arrays passed as props or state. Consider libraries like Immer for complex state updates."}`
- **Functional vs. OOP:** `{e.g., "Favor functional programming constructs (map, filter, reduce, pure functions) for data transformation and business logic where practical. Use classes for entities, services with clear state/responsibilities, or when framework conventions (e.g., NestJS) demand."}`
- **Error Handling Specifics:** `{e.g., "Always use `Error`objects or extensions thereof for`throw`. Ensure `Promise`rejections are always`Error`objects. Use custom error classes inheriting from a base`AppError` for domain-specific errors."}`
- **Null/Undefined Handling:** `{e.g., "Strict null checks (`strictNullChecks`) must be enabled. Avoid `\!` non-null assertion operator; prefer explicit checks, optional chaining (`?.`), or nullish coalescing (`??`). Define clear strategies for optional function parameters and return types."}`
- **Module System:** `{e.g., "Use ESModules (`import`/`export`) exclusively. Avoid CommonJS (`require`/`module.exports`) in new code."}`
- **Logging Specifics:** `{e.g., "Use the chosen structured logging library. Log messages must include a correlation ID. Do not log sensitive PII. Use appropriate log levels."}`
- **Framework Idioms (e.g., for NestJS/Express):** `{e.g., "NestJS: Always use decorators for defining modules, controllers, services, DTOs. Adhere strictly to the defined module structure and dependency injection patterns. Express: Define middleware patterns, routing structure."}`
- **Key Library Usage Conventions:** `{e.g., "When using Axios, create a single configured instance. For date/time, use {date-fns/Luxon/Day.js} and avoid native `Date` object for manipulations."}`
- **Code Generation Anti-Patterns to Avoid:** `{e.g., "Avoid overly nested conditional logic (max 2-3 levels). Avoid single-letter variable names (except for trivial loop counters like `i`, `j`, `k`). Do not write code that bypasses framework security features (e.g., ORM query builders)."}`
#### `{Language/Framework 2 Name, e.g., Python}` Specifics:
- **Immutability:** `{e.g., "Use tuples for immutable sequences. For classes, consider `@dataclass(frozen=True)`. Be mindful of mutable default arguments."}`
- **Functional vs. OOP:** `{e.g., "Employ classes for representing entities and services. Use functions for stateless operations. List comprehensions/generator expressions are preferred over `map/filter` for readability."}`
- **Error Handling Specifics:** `{e.g., "Always raise specific, custom exceptions inheriting from a base `AppException`. Use `try-except-else-finally`blocks appropriately. Avoid broad`except Exception:` clauses without re-raising or specific handling."}`
- **Resource Management:** `{e.g., "Always use `with` statements for resources like files or DB connections to ensure they are properly closed."}`
- **Type Hinting:** `{e.g., "All new functions and methods must have full type hints. Run MyPy in CI. Strive for `disallow_untyped_defs = True`."}`
- **Logging Specifics:** `{e.g., "Use the `logging`module configured for structured output (e.g., with`python-json-logger`). Include correlation IDs."}`
- **Framework Idioms (e.g., for Django/Flask/FastAPI):** `{e.g., "Django: Follow fat models, thin views pattern. Use ORM conventions. FastAPI: Utilize Pydantic for request/response models and dependency injection for services."}`
- **Key Library Usage Conventions:** `{e.g., "For HTTP requests, use `httpx`or`requests`with explicit timeout settings. For data manipulation, prefer`pandas` where appropriate but be mindful of performance."}`
#### `{Add more Language/Framework sections as needed...}`
- **{Consider other things that the trained LLM Dev Agent could potentially be random about specific to the chosen language technologies and platforms that it should be reminded of here}**
## Overall Testing Strategy
{This section outlines the project's comprehensive testing strategy, which all AI-generated and human-written code must adhere to. It complements the testing tools listed in the "Definitive Tech Stack Selections".}
- **Tools:** {Reiterate primary testing frameworks and libraries from Tech Stack, e.g., Jest, Playwright, PyTest, JUnit, Testcontainers.}
- **Unit Tests:**
- **Scope:** {Test individual functions, methods, classes, or small modules in isolation. Focus on business logic, algorithms, and transformation rules.}
- **Location:** {e.g., `*.test.ts`/`*.spec.ts` co-located with source files; `test_*.py` in a parallel `tests/` directory, following language conventions.}
- **Mocking/Stubbing:** {Specify chosen mocking library (e.g., Jest mocks, `unittest.mock` in Python, Mockito for Java). Mock all external dependencies (network calls, file system, databases, time).}
- **AI Agent Responsibility:** {AI Agent must generate unit tests covering all public methods, significant logic paths, edge cases, and error conditions for any new or modified code.}
- **Integration Tests:**
- **Scope:** {Test the interaction between several components or services within the application boundary. E.g., API endpoint to service layer to database (using a test database or in-memory version).}
- **Location:** {e.g., `/tests/integration` or `/src/integration-test` (Java).}
- **Environment:** {Specify how dependencies are handled (e.g., Testcontainers for databases/external services, in-memory databases, dedicated test environment).}
- **AI Agent Responsibility:** {AI Agent may be tasked with generating integration tests for key service interactions or API endpoints based on specifications.}
- **End-to-End (E2E) Tests:**
- **Scope:** {Validate complete user flows or critical paths through the system from the user's perspective (e.g., UI interaction, API call sequence).}
- **Tools:** {Reiterate E2E testing tools from Tech Stack (e.g., Playwright, Cypress, Selenium).}
- **AI Agent Responsibility:** {AI Agent may be tasked with generating E2E test stubs or scripts based on user stories or BDD scenarios. Focus on critical happy paths and key error scenarios.}
- **Test Coverage:**
- **Target:** {Specify target code coverage if any (e.g., 80% line/branch coverage for unit tests). This is a guideline; quality of tests is paramount over raw coverage numbers.}
- **Measurement:** {Tool used for coverage reports (e.g., Istanbul/nyc, Coverage.py, JaCoCo).}
- **Mocking/Stubbing Strategy (General):** {Beyond specific test types, outline general principles. e.g., "Prefer fakes or test doubles over extensive mocking where it improves test clarity and maintainability. Strive for tests that are fast, reliable, and isolated."}
- **Test Data Management:** {How is test data created, managed, and isolated? E.g., factories, fixtures, setup/teardown scripts, dedicated test data generation tools.}
## Security Best Practices
{Outline key security considerations relevant to the codebase. These are mandatory and must be actively addressed by the AI agent during development.}
- **Input Sanitization/Validation:** {Specify library/method for ALL external inputs (API requests, user-provided data, file uploads). E.g., 'Use class-validator with NestJS DTOs for all API inputs; all validation rules must be defined in DTOs.' For other languages, 'Use {validation_library} for all external inputs; define schemas and constraints.' Validation must occur at the boundary before processing.}
- **Output Encoding:** {Specify where and how output encoding should be performed to prevent XSS and other injection attacks. E.g., 'All dynamic data rendered in HTML templates must be contextually auto-escaped by the template engine (specify engine and confirm default behavior). If generating HTML/XML/JSON manually, use approved encoding libraries like {encoder_library_name}.'}
- **Secrets Management:** {Reference `docs/environment-vars.md` regarding storage for different environments. In code, access secrets _only_ through a designated configuration module/service. Never hardcode secrets, include them in source control, or log them. Use specific tools for local development if applicable (e.g., Doppler, .env files NOT committed).}
- **Dependency Security:** {Policy on checking for vulnerable dependencies. E.g., 'Run automated vulnerability scans (e.g., `npm audit`, `pip-audit`, Snyk, Dependabot alerts) as part of CI. Update vulnerable dependencies promptly based on severity.' Policy on adding new dependencies (vetting process).}
- **Authentication/Authorization Checks:** {Where and how should these be enforced? E.g., 'All API endpoints (except explicitly public ones) must enforce authentication using the central auth module/middleware. Authorization (permission/role checks) must be performed at the service layer or entry point for protected resources.' Define patterns for implementing these checks.}
- **Principle of Least Privilege (Implementation):** {e.g., 'Database connection users must have only the necessary permissions (SELECT, INSERT, UPDATE, DELETE) for the specific tables/schemas they access. IAM roles for cloud services must be narrowly scoped to the required actions and resources.'}
- **API Security (General):** {e.g., 'Enforce HTTPS. Implement rate limiting and throttling (specify tool/method). Use standard HTTP security headers (CSP, HSTS, X-Frame-Options, etc. - specify which ones and their configuration). Follow REST/GraphQL security best practices.'}
- **Error Handling & Information Disclosure:** {Ensure error messages do not leak sensitive information (stack traces, internal paths, detailed SQL errors) to the end-user. Log detailed errors server-side, provide generic messages or error IDs to the client.}
- **Regular Security Audits/Testing:** {Mention if planned, e.g., penetration testing, static/dynamic analysis tool usage in CI (SAST/DAST).}
- **{Other relevant practices, e.g., File upload security, Session management security, Data encryption at rest and in transit beyond HTTPS if specific requirements exist.}**

## Introduction
{ This document details the technical architecture specifically for the frontend of {Project Name}. It complements the main {Project Name} Architecture Document and the UI/UX Specification. This document details the frontend architecture and **builds upon the foundational decisions** (e.g., overall tech stack, CI/CD, primary testing tools) defined in the main {Project Name} Architecture Document (`docs/architecture.md` or linked equivalent). **Frontend-specific elaborations or deviations from general patterns must be explicitly noted here.** The goal is to provide a clear blueprint for frontend development, ensuring consistency, maintainability, and alignment with the overall system design and user experience goals. }
- **Link to Main Architecture Document (REQUIRED):** {e.g., `docs/architecture.md`}
- **Link to UI/UX Specification (REQUIRED if exists):** {e.g., `docs/front-end-spec.md`}
- **Link to Primary Design Files (Figma, Sketch, etc.) (REQUIRED if exists):** {From UI/UX Spec}
- **Link to Deployed Storybook / Component Showcase (if applicable):** {URL}
## Overall Frontend Philosophy & Patterns
{ Describe the core architectural decisions and patterns chosen for the frontend. This should align with the "Definitive Tech Stack Selections" in the main architecture document and consider implications from the overall system architecture (e.g., monorepo vs. polyrepo, backend service structure). }
- **Framework & Core Libraries:** {e.g., React 18.x with Next.js 13.x, Angular 16.x, Vue 3.x with Nuxt.js}. **These are derived from the 'Definitive Tech Stack Selections' in the main Architecture Document.** This section elaborates on *how* these choices are applied specifically to the frontend.
- **Component Architecture:** {e.g., Atomic Design principles, Presentational vs. Container components, use of specific component libraries like Material UI, Tailwind CSS for styling approach. Specify chosen approach and any key libraries.}
- **State Management Strategy:** {e.g., Redux Toolkit, Zustand, Vuex, NgRx. Briefly describe the overall approach global store, feature stores, context API usage. **Referenced from main Architecture Document and detailed further in "State Management In-Depth" section.**}
- **Data Flow:** {e.g., Unidirectional data flow (Flux/Redux pattern), React Query/SWR for server state. Describe how data is fetched, cached, passed to components, and updated.}
- **Styling Approach:** **{Chosen Styling Solution, e.g., Tailwind CSS / CSS Modules / Styled Components}**. Configuration File(s): {e.g., `tailwind.config.js`, `postcss.config.js`}. Key conventions: {e.g., "Utility-first approach for Tailwind. Custom components defined in `src/styles/components.css`. Theme extensions in `tailwind.config.js` under `theme.extend`. For CSS Modules, files are co-located with components, e.g., `MyComponent.module.css`.}
- **Key Design Patterns Used:** {e.g., Provider pattern, Hooks, Higher-Order Components, Service patterns for API calls, Container/Presentational. These patterns are to be consistently applied. Deviations require justification and documentation.}
## Detailed Frontend Directory Structure
{ Provide an ASCII diagram representing the frontend application\'s specific folder structure (e.g., within `src/` or `app/` or a dedicated `frontend/` root directory if part of a monorepo). This should elaborate on the frontend part of the main project structure outlined in the architecture document. Highlight conventions for organizing components, pages/views, services, state, styles, assets, etc. For each key directory, provide a one-sentence mandatory description of its purpose.}

### Notes on Frontend Structure:
{ Explain any specific conventions or rationale behind the structure. e.g., "Components are co-located with their feature if not globally reusable to improve modularity." AI Agent MUST adhere to this defined structure strictly. New files MUST be placed in the appropriate directory based on these descriptions. }
## Component Breakdown & Implementation Details
{ This section outlines the conventions and templates for defining UI components. Detailed specification for most feature-specific components will emerge as user stories are implemented. The AI agent MUST follow the "Template for Component Specification" below whenever a new component is identified for development. }
### Component Naming & Organization
- **Component Naming Convention:** **{e.g., PascalCase for files and component names: `UserProfileCard.tsx`}**. All component files MUST follow this convention.
- **Organization:** {e.g., "Globally reusable components in `src/components/ui/` or `src/components/layout/`. Feature-specific components co-located within their feature directory, e.g., `src/features/feature-name/components/`. Refer to Detailed Frontend Directory Structure.}
### Template for Component Specification
{ For each significant UI component identified from the UI/UX Specification and design files (Figma), the following details MUST be provided. Repeat this subsection for each component. The level of detail MUST be sufficient for an AI agent or developer to implement it with minimal ambiguity. }
#### Component: `{ComponentName}` (e.g., `UserProfileCard`, `ProductDetailsView`)
- **Purpose:** {Briefly describe what this component does and its role in the UI. MUST be clear and concise.}
- **Source File(s):** {e.g., `src/components/user-profile/UserProfileCard.tsx`. MUST be the exact path.}
- **Visual Reference:** {Link to specific Figma frame/component, or Storybook page. REQUIRED.}
- **Props (Properties):**
{ List each prop the component accepts. For each prop, all columns in the table MUST be filled. }
| Prop Name | Type | Required? | Default Value | Description |
| :-------------- | :---------------------------------------- | :-------- | :------------ | :--------------------------------------------------------------------------------------------------------- |
| `userId` | `string` | Yes | N/A | The ID of the user to display. MUST be a valid UUID. |
| `avatarUrl` | `string \| null` | No | `null` | URL for the user\'s avatar image. MUST be a valid HTTPS URL if provided. |
| `onEdit` | `() => void` | No | N/A | Callback function when an edit action is triggered. |
| `variant` | `\'compact\' \| \'full\'` | No | `\'full\'` | Controls the display mode of the card. |
| `{anotherProp}` | `{Specific primitive, imported type, or inline interface/type definition}` | {Yes/No} | {If any} | {MUST clearly state the prop\'s purpose and any constraints, e.g., \'Must be a positive integer.\'} |
- **Internal State (if any):**
{ Describe any significant internal state the component manages. Only list state that is *not* derived from props or global state. If state is complex, consider if it should be managed by a custom hook or global state solution instead. }
| State Variable | Type | Initial Value | Description |
| :-------------- | :-------- | :------------ | :----------------------------------------------------------------------------- |
| `isLoading` | `boolean` | `false` | Tracks if data for the component is loading. |
| `{anotherState}`| `{type}` | `{value}` | {Description of state variable and its purpose.} |
- **Key UI Elements / Structure:**
{ Provide a pseudo-HTML or JSX-like structure representing the component\'s DOM. Include key conditional rendering logic if applicable. **This structure dictates the primary output for the AI agent.** }
```html
<div> <!-- Main card container with specific class e.g., styles.cardFull or styles.cardCompact based on variant prop -->
<img src="{avatarUrl || defaultAvatar}" alt="User Avatar" class="{styles.avatar}" />
<h2>{userName}</h2>
<p class="{variant === 'full' ? styles.emailFull : styles.emailCompact}">{userEmail}</p>
{variant === 'full' && onEdit && <button onClick={onEdit} class="{styles.editButton}">Edit</button>}
</div>
```
- **Events Handled / Emitted:**
- **Handles:** {e.g., `onClick` on the edit button (triggers `onEdit` prop).}
- **Emits:** {If the component emits custom events/callbacks not covered by props, describe them with their exact signature. e.g., `onFollow: (payload: { userId: string; followed: boolean }) => void`}
- **Actions Triggered (Side Effects):**
- **State Management:** {e.g., "Dispatches `userSlice.actions.setUserName(newName)` from `src/store/slices/userSlice.ts`. Action payload MUST match the defined action creator." OR "Calls `updateUserProfileOptimistic(newData)` from a local `useReducer` hook."}
- **API Calls:** {Specify which service/function from the "API Interaction Layer" is called. e.g., "Calls `userService.fetchUser(userId)` from `src/services/userService.ts` on mount. Request payload: `{ userId }`. Success response populates internal state `userData`. Error response dispatches `uiSlice.actions.showErrorToast({ message: 'Failed to load user details' })`.}
- **Styling Notes:**
- {MUST reference specific Design System component names (e.g., "Uses `<Button variant='primary'>` from UI library") OR specify Tailwind CSS classes / CSS module class names to be applied (e.g., "Container uses `p-4 bg-white rounded-lg shadow-md`. Title uses `text-xl font-semibold`.") OR specify SCSS custom component classes to be applied (e.g., "Container uses `@apply p-4 bg-white rounded-lg shadow-md`. Title uses `@apply text-xl font-semibold`."). Any dynamic styling logic based on props or state MUST be described. If Tailwind CSS is used, list primary utility classes or `@apply` directives for custom component classes. AI Agent should prioritize direct utility class usage for simple cases and propose reusable component classes/React components for complex styling patterns.}
- **Accessibility Notes:**
- {MUST list specific ARIA attributes and their values (e.g., `aria-label="User profile card"`, `role="article"`), required keyboard navigation behavior (e.g., "Tab navigates to avatar, name, email, then edit button. Edit button is focusable and activated by Enter/Space."), and any focus management requirements (e.g., "If this component opens a modal, focus MUST be trapped inside. On modal close, focus returns to the trigger element.").}
---
_Repeat the above template for each significant component._
---
## State Management In-Depth
{ This section expands on the State Management strategy. **Refer to the main Architecture Document for the definitive choice of state management solution.** }
- **Chosen Solution:** {e.g., Redux Toolkit, Zustand, Vuex, NgRx - As defined in main arch doc.}
- **Decision Guide for State Location:**
- **Global State (e.g., Redux/Zustand):** Data shared across many unrelated components; data persisting across routes; complex state logic managed via reducers/thunks. **MUST be used for session data, user preferences, application-wide notifications.**
- **React Context API:** State primarily passed down a specific component subtree (e.g., theme, form context). Simpler state, fewer updates compared to global state. **MUST be used for localized state not suitable for prop drilling but not needed globally.**
- **Local Component State (`useState`, `useReducer`):** UI-specific state, not needed outside the component or its direct children (e.g., form input values, dropdown open/close status). **MUST be the default choice unless criteria for Context or Global State are met.**
### Store Structure / Slices
{ Describe the conventions for organizing the global state (e.g., "Each major feature requiring global state will have its own Redux slice located in `src/features/[featureName]/store.ts`"). }
- **Core Slice Example (e.g., `sessionSlice` in `src/store/slices/sessionSlice.ts`):**
- **Purpose:** {Manages user session, authentication status, and basic user profile info accessible globally.}
- **State Shape (Interface/Type):**
```typescript
interface SessionState {
currentUser: { id: string; name: string; email: string; roles: string[]; } | null;
isAuthenticated: boolean;
token: string | null;
status: "idle" | "loading" | "succeeded" | "failed";
error: string | null;
}
```
- **Key Reducers/Actions (within `createSlice`):** {Briefly list main synchronous actions, e.g., `setCurrentUser`, `clearSession`, `setAuthStatus`, `setAuthError`.}
- **Async Thunks (if any):** {List key async thunks, e.g., `loginUserThunk`, `fetchUserProfileThunk`.}
- **Selectors (memoized with `createSelector`):** {List key selectors, e.g., `selectCurrentUser`, `selectIsAuthenticated`.}
- **Feature Slice Template (e.g., `{featureName}Slice` in `src/features/{featureName}/store.ts`):**
- **Purpose:** {To be filled out when a new feature requires its own state slice.}
- **State Shape (Interface/Type):** {To be defined by the feature.}
- **Key Reducers/Actions (within `createSlice`):** {To be defined by the feature.}
- **Async Thunks (if any, defined using `createAsyncThunk`):** {To be defined by the feature.}
- **Selectors (memoized with `createSelector`):** {To be defined by the feature.}
- **Export:** {All actions and selectors MUST be exported.}
### Key Selectors
{ List important selectors for any core, upfront slices. For emergent feature slices, selectors will be defined with the slice. **ALL selectors deriving data or combining multiple state pieces MUST use `createSelector` from Reselect (or equivalent for other state libraries) for memoization.** }
- **`selectCurrentUser` (from `sessionSlice`):** {Returns the `currentUser` object.}
- **`selectIsAuthenticated` (from `sessionSlice`):** {Returns `isAuthenticated` boolean.}
- **`selectAuthToken` (from `sessionSlice`):** {Returns the `token` from `sessionSlice`.}
### Key Actions / Reducers / Thunks
{ Detail more complex actions for core, upfront slices, especially asynchronous thunks or sagas. Each thunk MUST clearly define its purpose, parameters, API calls made (referencing the API Interaction Layer), and how it updates the state on pending, fulfilled, and rejected states. }
- **Core Action/Thunk Example: `authenticateUser(credentials: AuthCredentials)` (in `sessionSlice.ts`):**
- **Purpose:** {Handles user login by calling the auth API and updating the `sessionSlice`.}
- **Parameters:** `credentials: { email: string; password: string }`
- **Dispatch Flow (using Redux Toolkit `createAsyncThunk`):**
1. On `pending`: Dispatches `sessionSlice.actions.setAuthStatus('loading')`.
2. Calls `authService.login(credentials)` (from `src/services/authService.ts`).
3. On `fulfilled` (success): Dispatches `sessionSlice.actions.setCurrentUser(response.data.user)`, `sessionSlice.actions.setToken(response.data.token)`, `sessionSlice.actions.setAuthStatus('succeeded')`.
4. On `rejected` (error): Dispatches `sessionSlice.actions.setAuthError(error.message)`, `sessionSlice.actions.setAuthStatus('failed')`.
- **Feature Action/Thunk Template: `{featureActionName}` (in `{featureName}Slice.ts`):**
- **Purpose:** {To be filled out for feature-specific async operations.}
- **Parameters:** {Define specific parameters with types.}
- **Dispatch Flow (using `createAsyncThunk`):** {To be defined by the feature, following similar patterns for pending, fulfilled, rejected states, including API calls and state updates.}
## API Interaction Layer
{ Describe how the frontend communicates with the backend APIs defined in the main Architecture Document. }
### Client/Service Structure
- **HTTP Client Setup:** {e.g., Axios instance in `src/services/apiClient.ts`. **MUST** include: Base URL (from environment variable `NEXT_PUBLIC_API_URL` or equivalent), default headers (e.g., `Content-Type: 'application/json'`), interceptors for automatic auth token injection (from state management, e.g., `sessionSlice.token`) and standardized error handling/normalization (see below).}
- **Service Definitions (Example):**
- **`userService.ts` (in `src/services/userService.ts`):**
- **Purpose:** {Handles all API interactions related to users.}
- **Functions:** Each service function MUST have explicit parameter types, a return type (e.g., `Promise<User>`), JSDoc/TSDoc explaining purpose, params, return value, and any specific error handling. It MUST call the configured HTTP client (`apiClient`) with correct endpoint, method, and payload.
- `fetchUser(userId: string): Promise<User>`
- `updateUserProfile(userId: string, data: UserProfileUpdateDto): Promise<User>`
- **`productService.ts` (in `src/services/productService.ts`):**
- **Purpose:** {...}
- **Functions:** {...}
### Error Handling & Retries (Frontend)
- **Global Error Handling:** {How are API errors caught globally? (e.g., Via Axios response interceptor in `apiClient.ts`). How are they presented/logged? (e.g., Dispatches `uiSlice.actions.showGlobalErrorBanner({ message: error.message })`, logs detailed error to console/monitoring service). Is there a global error state? (e.g., `uiSlice.error`).}
- **Specific Error Handling:** {Components MAY handle specific API errors locally for more contextual feedback (e.g., displaying an inline message on a form field: "Invalid email address"). This MUST be documented in the component's specification if it deviates from global handling.}
- **Retry Logic:** {Is client-side retry logic implemented (e.g., using `axios-retry` with `apiClient`)? If so, specify configuration: max retries (e.g., 3), retry conditions (e.g., network errors, 5xx server errors), retry delay (e.g., exponential backoff). **MUST apply only to idempotent requests (GET, PUT, DELETE).**}
## Routing Strategy
{ Detail how navigation and routing are handled in the frontend application. }
- **Routing Library:** {e.g., React Router, Next.js App Router, Vue Router, Angular Router. As per main Architecture Document.}
### Route Definitions
{ List the main routes of the application and the primary component/page rendered for each. }
| Path Pattern | Component/Page (`src/app/...` or `src/pages/...`) | Protection | Notes |
| :--------------------- | :-------------------------------------------------- | :------------------------------ | :---------------------------------------------------- |
| `/` | `app/page.tsx` or `pages/HomePage.tsx` | `Public` | |
| `/login` | `app/login/page.tsx` or `pages/LoginPage.tsx` | `Public` (redirect if auth) | Redirects to `/dashboard` if already authenticated. |
| `/dashboard` | `app/dashboard/page.tsx` or `pages/DashboardPage.tsx` | `Authenticated` | |
| `/products` | `app/products/page.tsx` | `Public` | |
| `/products/:productId` | `app/products/[productId]/page.tsx` | `Public` | Parameter: `productId` (string) |
| `/settings/profile` | `app/settings/profile/page.tsx` | `Authenticated`, `Role:[USER]` | Example of role-based protection. |
| `{anotherRoute}` | `{ComponentPath}` | `{Public/Authenticated/Role:[ROLE_NAME]}` | {Notes, parameter names and types} |
### Route Guards / Protection
- **Authentication Guard:** {Describe how routes are protected based on authentication status. **Specify the exact HOC, hook, layout, or middleware mechanism and its location** (e.g., `src/guards/AuthGuard.tsx`, or Next.js middleware in `middleware.ts`). Logic MUST use authentication state from the `sessionSlice` (or equivalent). Unauthenticated users attempting to access protected routes MUST be redirected to `/login` (or specified login path).}
- **Authorization Guard (if applicable):** {Describe how routes might be protected based on user roles or permissions. **Specify the exact mechanism**, similar to Auth Guard. Unauthorized users (authenticated but lacking permissions) MUST be shown a "Forbidden" page or redirected to a safe page.}
## Build, Bundling, and Deployment
{ Details specific to the frontend build and deployment process, complementing the "Infrastructure and Deployment Overview" in the main architecture document. }
### Build Process & Scripts
- **Key Build Scripts (from `package.json`):** {e.g., `"build": "next build"`. What do they do? Point to `package.json` scripts. `"dev": "next dev"`, `"start": "next start"`.}. **AI Agent MUST NOT generate code that hardcodes environment-specific values. All such values MUST be accessed via the defined environment configuration mechanism.** Specify the exact files and access method.
- **Environment Configuration Management:** {How are `process.env.NEXT_PUBLIC_API_URL` (or equivalent like `import.meta.env.VITE_API_URL`) managed for different environments (dev, staging, prod)? (e.g., `.env`, `.env.development`, `.env.production` files for Next.js/Vite; build-time injection via CI variables). Specify the exact files and access method.}
### Key Bundling Optimizations
- **Code Splitting:** {How is it implemented/ensured? (e.g., "Next.js/Vite handles route-based code splitting automatically. For component-level code splitting, dynamic imports `React.lazy(() => import('./MyComponent'))` or `import('./heavy-module')` MUST be used for non-critical large components/libraries.")}
- **Tree Shaking:** {How is it implemented/ensured? (e.g., "Ensured by modern build tools like Webpack/Rollup (used by Next.js/Vite) when using ES Modules. Avoid side-effectful imports in shared libraries.")}
- **Lazy Loading (Components, Images, etc.):** {Strategy for lazy loading. (e.g., "Components: `React.lazy` with `Suspense`. Images: Use framework-specific Image component like `next/image` which handles lazy loading by default, or `loading='lazy'` attribute for standard `<img>` tags.")}
- **Minification & Compression:** {Handled by build tools (e.g., Webpack/Terser, Vite/esbuild)? Specify if any specific configuration is needed. Compression (e.g., Gzip, Brotli) is typically handled by the hosting platform/CDN.}
### Deployment to CDN/Hosting
- **Target Platform:** {e.g., Vercel, Netlify, AWS S3/CloudFront, Azure Static Web Apps. As per main Architecture Document.}
- **Deployment Trigger:** {e.g., Git push to `main` branch via GitHub Actions (referencing main CI/CD pipeline).}
- **Asset Caching Strategy:** {How are static assets cached? (e.g., "Immutable assets (JS/CSS bundles with content hashes) have `Cache-Control: public, max-age=31536000, immutable`. HTML files have `Cache-Control: no-cache` or short max-age (e.g., `public, max-age=0, must-revalidate`) to ensure users get fresh entry points. Configured via {hosting platform settings / `next.config.js` headers / CDN rules}.}
## Frontend Testing Strategy
{ This section elaborates on the "Testing Strategy" from the main architecture document, focusing on frontend-specific aspects. **Refer to the main Architecture Document for definitive choices of testing tools.** }
- **Link to Main Overall Testing Strategy:** {Reference the main `docs/architecture.md#overall-testing-strategy` or equivalent.}
### Component Testing
- **Scope:** {Testing individual UI components in isolation (similar to unit tests for components).}
- **Tools:** {e.g., React Testing Library with Jest, Vitest, Vue Test Utils, Angular Testing Utilities. As per main Arch Doc.}
- **Focus:** {Rendering with various props, user interactions (clicks, input changes using `fireEvent` or `userEvent`), event emission, basic internal state changes. **Snapshot testing MUST be used sparingly and with clear justification (e.g., for very stable, purely presentational components with complex DOM structure); prefer explicit assertions.**}
- **Location:** {e.g., `*.test.tsx` or `*.spec.tsx` co-located alongside components, or in a `__tests__` subdirectory.}
### Feature/Flow Testing (UI Integration)
- **Scope:** {Testing how multiple components interact to fulfill a small user flow or feature within a page, potentially mocking API calls or global state management. e.g., testing a complete form submission within a feature, including validation and interaction with a mocked service layer.}
- **Tools:** {Same as component testing (e.g., React Testing Library with Jest/Vitest), but with more complex setups involving mock providers for routing, state, API calls.}
- **Focus:** {Data flow between components, conditional rendering based on interactions, navigation within a feature, integration with mocked services/state.}
### End-to-End UI Testing Tools & Scope
- **Tools:** {Reiterate from main Testing Strategy, e.g., Playwright, Cypress, Selenium.}
- **Scope (Frontend Focus):** {Define 3-5 key user journeys that MUST be covered by E2E UI tests from a UI perspective, e.g., "User registration and login flow", "Adding an item to cart and proceeding to the checkout page summary", "Submitting a complex multi-step form and verifying success UI state and data persistence (via API mocks or a test backend)."}
- **Test Data Management for UI:** {How is consistent test data seeded or mocked for UI E2E tests? (e.g., API mocking layer like MSW, backend seeding scripts, dedicated test accounts).}
## Accessibility (AX) Implementation Details
{ Based on the AX requirements in the UI/UX Specification, detail how these will be technically implemented. }
- **Semantic HTML:** {Emphasis on using correct HTML5 elements. **AI Agent MUST prioritize semantic elements (e.g., `<nav>`, `<button>`, `<article>`) over generic `<div>`/`<span>` with ARIA roles where a native element with the correct semantics exists.**}
- **ARIA Implementation:** {Specify common custom components and their required ARIA patterns (e.g., "Custom select dropdown MUST follow ARIA Combobox pattern including `aria-expanded`, `aria-controls`, `role='combobox'`, etc. Custom Tabs MUST follow ARIA Tabbed Interface pattern."). Link to ARIA Authoring Practices Guide (APG) for reference.}
- **Keyboard Navigation:** {Ensuring all interactive elements are focusable and operable via keyboard. Focus order MUST be logical. Custom components MUST implement keyboard interaction patterns as per ARIA APG (e.g., arrow keys for radio groups/sliders).**}
- **Focus Management:** {How is focus managed in modals, dynamic content changes, route transitions? (e.g., "Modals MUST trap focus. On modal open, focus moves to the first focusable element or the modal container. On close, focus returns to the trigger element. Route changes SHOULD move focus to the main content area or H1 of the new page.")}
- **Testing Tools for AX:** {e.g., Axe DevTools browser extension, Lighthouse accessibility audit. **Automated Axe scans (e.g., using `jest-axe` for component tests, or Playwright/Cypress Axe integration for E2E tests) MUST be integrated into the CI pipeline and fail the build on new violations of WCAG AA (or specified level).** Manual testing procedures: {List key manual checks, e.g., keyboard-only navigation for all interactive elements, screen reader testing (e.g., NVDA/JAWS/VoiceOver) for critical user flows.}}
## Performance Considerations
{ Highlight frontend-specific performance optimization strategies. }
- **Image Optimization:** {Formats (e.g., WebP), responsive images (`<picture>`, `srcset`), lazy loading.}
- Implementation Mandate: {e.g., "All images MUST use `<Image>` component from Next.js (or equivalent framework-specific optimizer). SVGs for icons. WebP format preferred where supported."}
- **Code Splitting & Lazy Loading (reiterate from Build section if needed):** {How it impacts perceived performance.}
- Implementation Mandate: {e.g., "Next.js handles route-based code splitting automatically. Dynamic imports `import()` MUST be used for component-level lazy loading."}
- **Minimizing Re-renders:** {Techniques like `React.memo`, `shouldComponentUpdate`, optimized selectors.}
- Implementation Mandate: {e.g., "`React.memo` MUST be used for components that render frequently with same props. Selectors for global state MUST be memoized (e.g., with Reselect). Avoid passing new object/array literals or inline functions as props directly in render methods where it can cause unnecessary re-renders."}
- **Debouncing/Throttling:** {For event handlers like search input or window resize.}
- Implementation Mandate: {e.g., "Use a utility like `lodash.debounce` or `lodash.throttle` for specified event handlers. Define debounce/throttle wait times."}
- **Virtualization:** {For long lists or large data sets (e.g., React Virtualized, TanStack Virtual).}
- Implementation Mandate: {e.g., "MUST be used for any list rendering more than {N, e.g., 100} items if performance degradation is observed."}
- **Caching Strategies (Client-Side):** {Use of browser cache, service workers for PWA capabilities (if applicable).}
- Implementation Mandate: {e.g., "Configure service worker (if PWA) to cache application shell and key static assets. Leverage HTTP caching headers for other assets as defined in Deployment section."}
- **Performance Monitoring Tools:** {e.g., Lighthouse, WebPageTest, browser DevTools performance tab. Specify which ones are primary and any automated checks in CI.}
## Internationalization (i18n) and Localization (l10n) Strategy
{This section defines the strategy for supporting multiple languages and regional differences if applicable. If not applicable, state "Internationalization is not a requirement for this project at this time."}
- **Requirement Level:** {e.g., Not Required, Required for specific languages [list them], Fully internationalized for future expansion.}
- **Chosen i18n Library/Framework:** {e.g., `react-i18next`, `vue-i18n`, `ngx-translate`, framework-native solution like Next.js i18n routing. Specify the exact library/mechanism.}
- **Translation File Structure & Format:** {e.g., JSON files per language per feature (`src/features/{featureName}/locales/{lang}.json`), or global files (`public/locales/{lang}.json`). Define the exact path and format (e.g., flat JSON, nested JSON).}
- **Translation Key Naming Convention:** {e.g., `featureName.componentName.elementText`, `common.submitButton`. MUST be a clear, consistent, and documented pattern.}
- **Process for Adding New Translatable Strings:** {e.g., "AI Agent MUST add new keys to the default language file (e.g., `en.json`) and use the i18n library's functions/components (e.g., `<Trans>` component, `t()` function) to render text. Keys MUST NOT be constructed dynamically at runtime in a way that prevents static analysis."}
- **Handling Pluralization:** {Specify method/syntax, e.g., using ICU message format via the chosen library (e.g., `t('key', { count: N })`).}
- **Date, Time, and Number Formatting:** {Specify if the i18n library handles this, or if another library (e.g., `date-fns-tz` with locale support, `Intl` API directly) and specific formats/styles should be used for each locale.}
- **Default Language:** {e.g., `en-US`}
- **Language Switching Mechanism (if applicable):** {How is the language changed by the user and persisted? e.g., "Via a language selector component that updates a global state/cookie and potentially alters the URL route."}
## Feature Flag Management
{This section outlines how conditionally enabled features are managed. If not applicable, state "Feature flags are not a primary architectural concern for this project at this time."}
- **Requirement Level:** {e.g., Not Required, Used for specific rollouts, Core part of development workflow.}
- **Chosen Feature Flag System/Library:** {e.g., LaunchDarkly, Unleash, Flagsmith, custom solution using environment variables or a configuration service. Specify the exact tool/method.}
- **Accessing Flags in Code:** {e.g., "Via a custom hook `useFeatureFlag('flag-name'): boolean` or a service `featureFlagService.isOn('flag-name')`. Specify the exact interface, location, and initialization of the service/provider."}
- **Flag Naming Convention:** {e.g., `[SCOPE]_[FEATURE_NAME]_[TARGET_GROUP_OR_TYPE]`, e.g., `CHECKOUT_NEW_PAYMENT_GATEWAY_ROLLOUT`, `USER_PROFILE_BETA_AVATAR_UPLOAD`. MUST be documented and consistently applied.}
- **Code Structure for Flagged Features:** {e.g., "Use conditional rendering (`{isFeatureEnabled && <NewComponent />}`). For larger features, conditionally import components (`React.lazy` with flag check) or routes. Avoid complex branching logic deep within shared components; prefer to flag at higher levels."}
- **Strategy for Code Cleanup (Post-Flag Retirement):** {e.g., "Once a flag is fully rolled out (100% users) and deemed permanent, or fully removed, all conditional logic, old code paths, and the flag itself MUST be removed from the codebase within {N, e.g., 2} sprints. This is a mandatory tech debt item."}
- **Testing Flagged Features:** {How are different flag variations tested? e.g., "QA team uses a debug panel to toggle flags. Automated E2E tests run with specific flag configurations."}
## Frontend Security Considerations
{This section highlights mandatory frontend-specific security practices, complementing the main Architecture Document. AI Agent MUST adhere to these guidelines.}
- **Cross-Site Scripting (XSS) Prevention:**
- Framework Reliance: {e.g., "React's JSX auto-escaping MUST be relied upon for rendering dynamic content. Vue's `v-html` MUST be avoided unless content is explicitly sanitized."}
- Explicit Sanitization: {If direct DOM manipulation is unavoidable (strongly discouraged), use {specific sanitization library/function like DOMPurify}. Specify its configuration.}
- Content Security Policy (CSP): {Is a CSP implemented? How? e.g., "CSP is enforced via HTTP headers set by the backend/CDN as defined in the main Architecture doc. Frontend MAY need to ensure nonce usage for inline scripts if `unsafe-inline` is not allowed." Link to CSP definition if available.}
- **Cross-Site Request Forgery (CSRF) Protection (if applicable for session-based auth):**
- Mechanism: {e.g., "Backend uses synchronizer token pattern. Frontend ensures tokens are included in state-changing requests if not handled automatically by HTTP client or forms." Refer to main Architecture Document for backend details.}
- **Secure Token Storage & Handling (for client-side tokens like JWTs):**
- Storage Mechanism: {**MUST specify exact mechanism**: e.g., In-memory via state management (e.g., Redux/Zustand store, cleared on tab close), `HttpOnly` cookies (if backend sets them and frontend doesn't need to read them), `sessionStorage`. **`localStorage` is STRONGLY DISCOURAGED for token storage.**}
- Token Refresh: {Describe client-side involvement, e.g., "Interceptor in `apiClient.ts` handles 401 errors to trigger token refresh endpoint."}
- **Third-Party Script Security:**
- Policy: {e.g., "All third-party scripts (analytics, ads, widgets) MUST be vetted for necessity and security. Load scripts asynchronously (`async/defer`)."}
- Subresource Integrity (SRI): {e.g., "SRI hashes MUST be used for all external scripts and stylesheets loaded from CDNs where the resource is stable."}
- **Client-Side Data Validation:**
- Purpose: {e.g., "Client-side validation is for UX improvement (immediate feedback) ONLY. **All critical data validation MUST occur server-side** (as defined in the main Architecture Document)."}
- Implementation: {e.g., "Use {form_library_name like Formik/React Hook Form} for form validation. Rules should mirror server-side validation where appropriate."}
- **Preventing Clickjacking:**
- Mechanism: {e.g., "Primary defense is `X-Frame-Options` or `frame-ancestors` CSP directive, set by backend/CDN. Frontend code should not rely on frame-busting scripts."}
- **API Key Exposure (for client-side consumed services):**
- Restriction: {e.g., "API keys for services like Google Maps (client-side JS SDK) MUST be restricted (e.g., HTTP referrer, IP address, API restrictions) via the service provider's console."}
- Backend Proxy: {e.g., "For keys requiring more secrecy or involving sensitive operations, a backend proxy endpoint MUST be created; frontend calls the proxy, not the third-party service directly."}
- **Secure Communication (HTTPS):**
- Mandate: {e.g., "All communication with backend APIs MUST use HTTPS. Mixed content (HTTP assets on HTTPS page) is forbidden."}
- **Dependency Vulnerabilities:**
- Process: {e.g., "Run `npm audit --audit-level=high` (or equivalent) in CI. High/critical vulnerabilities MUST be addressed before deployment. Monitor Dependabot/Snyk alerts."}
## Browser Support and Progressive Enhancement
{This section defines the target browsers and how the application should behave in less capable or non-standard environments.}
- **Target Browsers:** {e.g., "Latest 2 stable versions of Chrome, Firefox, Safari, Edge. Specific versions can be listed if required by project constraints. Internet Explorer (any version) is NOT supported." MUST be explicit.}
- **Polyfill Strategy:**
- Mechanism: {e.g., "Use `core-js@3` imported at the application entry point. Babel `preset-env` is configured with the above browser targets to include necessary polyfills."}
- Specific Polyfills (if any beyond `core-js`): {List any other polyfills required for specific features, e.g., `smoothscroll-polyfill`.}
- **JavaScript Requirement & Progressive Enhancement:**
- Baseline: {e.g., "Core application functionality REQUIRES JavaScript enabled in the browser." OR "Key content (e.g., articles, product information) and primary navigation MUST be accessible and readable without JavaScript. Interactive features and enhancements are layered on top with JavaScript (Progressive Enhancement approach)." Specify the chosen approach.}
- No-JS Experience (if Progressive Enhancement): {Describe what works without JS. e.g., "Users can view pages and navigate. Forms may not submit or will use standard HTML submission."}
- **CSS Compatibility & Fallbacks:**
- Tooling: {e.g., "Use Autoprefixer (via PostCSS) configured with the target browser list to add vendor prefixes."}
- Feature Usage: {e.g., "Avoid CSS features not supported by >90% of target browsers unless a graceful degradation or fallback is explicitly defined and tested (e.g., using `@supports` queries)."}
- **Accessibility Fallbacks:** {Consider how features behave if certain ARIA versions or advanced accessibility features are not supported by older assistive technologies within the support matrix.}

# {{Project Name}} Product Requirements Document (PRD)
[[LLM: If available, review any provided document or ask if any are optionally available: Project Brief]]
## Goals and Background Context
[[LLM: Populate the 2 child sections based on what we have received from user description or the provided brief. Allow user to review the 2 sections and offer changes before proceeding]]
### Goals
[[LLM: Bullet list of 1 line desired outcomes the PRD will deliver if successful - user and project desires]]
### Background Context
[[LLM: 1-2 short paragraphs summarizing the background context, such as what we learned in the brief without being redundant with the goals, what and why this solves a problem, what the current landscape or need is etc...]]
## Requirements
[[LLM: Draft the list of functional and non functional requirements under the two child sections, and immediately execute tasks#advanced-elicitation display]]
### Functional
[[LLM: Each Requirement will be a bullet markdown and an identifier sequence starting with FR`.]]
@{example: - FR6: The Todo List uses AI to detect and warn against adding potentially duplicate todo items that are worded differently.}
### Non Functional
[[LLM: Each Requirement will be a bullet markdown and an identifier sequence starting with NFR`.]]
@{example: - NFR1: AWS service usage **must** aim to stay within free-tier limits where feasible.}
^^CONDITION: has_ui^^
## User Interface Design Goals
[[LLM: Capture high-level UI/UX vision to guide Design Architect and to inform story creation. Steps:
1. Pre-fill all subsections with educated guesses based on project context
2. Present the complete rendered section to user
3. Clearly let the user know where assumptions were made
4. Ask targeted questions for unclear/missing elements or areas needing more specification
5. This is NOT detailed UI spec - focus on product vision and user goals
6. After section completion, immediately apply `tasks#advanced-elicitation` protocol]]
### Overall UX Vision
### Key Interaction Paradigms
### Core Screens and Views
[[LLM: From a product perspective, what are the most critical screens or views necessary to deliver the the PRD values and goals? This is meant to be Conceptual High Level to Drive Rough Epic or User Stories]]
@{example}
- Login Screen
- Main Dashboard
- Item Detail Page
- Settings Page
@{/example}
### Accessibility: { None, WCAG, etc }
### Branding
[[LLM: Any known branding elements or style guides that must be incorporated?]]
@{example}
- Replicate the look and feel of early 1900s black and white cinema, including animated effects replicating film damage or projector glitches during page or state transitions.
- Attached is the full color pallet and tokens for our corporate branding.
@{/example}
### Target Device and Platforms
@{example}
"Web Responsive, and all mobile platforms", "IPhone Only", "ASCII Windows Desktop"
@{/example}
^^/CONDITION: has_ui^^
## Technical Assumptions
[[LLM: Gather technical decisions that will guide the Architect. Steps:
1. Check if `data#technical-preferences` file exists - use it to pre-populate choices
2. Ask user about: languages, frameworks, starter templates, libraries, APIs, deployment targets
3. For unknowns, offer guidance based on project goals and MVP scope
4. Document ALL technical choices with rationale (why this choice fits the project)
5. These become constraints for the Architect - be specific and complete
6. After section completion, apply `tasks#advanced-elicitation` protocol.]]
### Repository Structure: { Monorepo, Polyrepo, etc...}
### Service Architecture
[[LLM: CRITICAL DECISION - Document the high-level service architecture (e.g., Monolith, Microservices, Serverless functions within a Monorepo).]]
### Testing requirements
[[LLM: CRITICAL DECISION - Document the testing requirements, unit only, integration, e2e, manual, need for manual testing convenience methods).]]
### Additional Technical Assumptions and Requests
[[LLM: Throughout the entire process of drafting this document, if any other technical assumptions are raised or discovered appropriate for the architect, add them here as additional bulleted items]]
## Epics
[[LLM: First, present a high-level list of all epics for user approval, the epic_list and immediately execute tasks#advanced-elicitation display. Each epic should have a title and a short (1 sentence) goal statement. This allows the user to review the overall structure before diving into details.
CRITICAL: Epics MUST be logically sequential following agile best practices:
- Each epic should deliver a significant, end-to-end, fully deployable increment of testable functionality
- Epic 1 must establish foundational project infrastructure (app setup, Git, CI/CD, core services) unless we are adding new functionality to an existing app, while also delivering an initial piece of functionality, even as simple as a health-check route or display of a simple canary page
- Each subsequent epic builds upon previous epics' functionality delivering major blocks of functionality that provide tangible value to users or business when deployed
- Not every project needs multiple epics, an epic needs to deliver value. For example, an API completed can deliver value even if a UI is not complete and planned for a separate epic.
- Err on the side of less epics, but let the user know your rationale and offer options for splitting them if it seems some are too large or focused on disparate things.
- Cross Cutting Concerns should flow through epics and stories and not be final stories. For example, adding a logging framework as a last story of an epic, or at the end of a project as a final epic or story would be terrible as we would not have logging from the beginning.]]
<<REPEAT: epic_list>>
- Epic{{epic_number}} {{epic_title}}: {{short_goal}}
<</REPEAT>>
@{example: epic_list}
1. Foundation & Core Infrastructure: Establish project setup, authentication, and basic user management
2. Core Business Entities: Create and manage primary domain objects with CRUD operations
3. User Workflows & Interactions: Enable key user journeys and business processes
4. Reporting & Analytics: Provide insights and data visualization for users
@{/example}
[[LLM: After the epic list is approved, present each `epic_details` with all its stories and acceptance criteria as a complete review unit and immediately execute tasks#advanced-elicitation display, before moving on to the next epic.]]
<<REPEAT: epic_details>>
## Epic {{epic_number}} {{epic_title}}
{{epic_goal}} [[LLM: Expanded goal - 2-3 sentences describing the objective and value all the stories will achieve]]
[[LLM: CRITICAL STORY SEQUENCING REQUIREMENTS:
- Stories within each epic MUST be logically sequential
- Each story should be a "vertical slice" delivering complete functionality
- No story should depend on work from a later story or epic
- Identify and note any direct prerequisite stories
- Focus on "what" and "why" not "how" (leave technical implementation to Architect) yet be precise enough to support a logical sequential order of operations from story to story.
- Ensure each story delivers clear user or business value, try to avoid enablers and build them into stories that deliver value.
- Size stories for AI agent execution: Each story must be completable by a single AI agent in one focused session without context overflow
- Think "junior developer working for 2-4 hours" - stories must be small, focused, and self-contained
- If a story seems complex, break it down further as long as it can deliver a vertical slice
- Each story should result in working, testable code before the agent's context window fills]]
<<REPEAT: story>>
### Story {{epic_number}}.{{story_number}} {{story_title}}
As a {{user_type}},
I want {{action}},
so that {{benefit}}.
#### Acceptance Criteria
[[LLM: Define clear, comprehensive, and testable acceptance criteria that:
- Precisely define what "done" means from a functional perspective
- Are unambiguous and serve as basis for verification
- Include any critical non-functional requirements from the PRD
- Consider local testability for backend/data components
- Specify UI/UX requirements and framework adherence where applicable
- Avoid cross-cutting concerns that should be in other stories or PRD sections]]
