-## Requirements - -- Node.js 14.0.0 or higher -- Anthropic API key (Claude API) -- Anthropic SDK version 0.39.0 or higher -- OpenAI SDK (for Perplexity API integration, optional) - -## Configuration - -The script can be configured through environment variables in a `.env` file at the root of the project: - -### Required Configuration -- `ANTHROPIC_API_KEY`: Your Anthropic API key for Claude - -### Optional Configuration -- `MODEL`: Specify which Claude model to use (default: "claude-3-7-sonnet-20250219") -- `MAX_TOKENS`: Maximum tokens for model responses (default: 4000) -- `TEMPERATURE`: Temperature for model responses (default: 0.7) -- `PERPLEXITY_API_KEY`: Your Perplexity API key for research-backed subtask generation -- `PERPLEXITY_MODEL`: Specify which Perplexity model to use (default: "sonar-medium-online") -- `DEBUG`: Enable debug logging (default: false) -- `LOG_LEVEL`: Log level - debug, info, warn, error (default: info) -- `DEFAULT_SUBTASKS`: Default number of subtasks when expanding (default: 3) -- `DEFAULT_PRIORITY`: Default priority for generated tasks (default: medium) -- `PROJECT_NAME`: Override default project name in tasks.json -- `PROJECT_VERSION`: Override default version in tasks.json - -## Installation - -```bash -# Install globally -npm install -g task-master-ai - -# OR install locally within your project -npm install task-master-ai -```` - -### Initialize a new project - -```bash -# If installed globally -task-master init - -# If installed locally -npx task-master-init -``` - -This will prompt you for project details and set up a new project with the necessary files and structure. - -### Important Notes - -1. This package uses ES modules. Your package.json should include `"type": "module"`. -2. The Anthropic SDK version should be 0.39.0 or higher. - -## Quick Start with Global Commands - -After installing the package globally, you can use these CLI commands from any directory: - -```bash -# Initialize a new project -task-master init - -# Parse a PRD and generate tasks -task-master parse-prd your-prd.txt - -# List all tasks -task-master list - -# Show the next task to work on -task-master next - -# Generate task files -task-master generate -``` - -## Troubleshooting - -### If `task-master init` doesn't respond: - -Try running it with Node directly: - -```bash -node node_modules/claude-task-master/scripts/init.js -``` - -Or clone the repository and run: - -```bash -git clone https://github.com/eyaltoledano/claude-task-master.git -cd claude-task-master -node scripts/init.js -``` - -## Task Structure - -Tasks in tasks.json have the following structure: - -- `id`: Unique identifier for the task (Example: `1`) -- `title`: Brief, descriptive title of the task (Example: `"Initialize Repo"`) -- `description`: Concise description of what the task involves (Example: `"Create a new repository, set up initial structure."`) -- `status`: Current state of the task (Example: `"pending"`, `"done"`, `"deferred"`) -- `dependencies`: IDs of tasks that must be completed before this task (Example: `[1, 2]`) - - Dependencies are displayed with status indicators (✅ for completed, ⏱️ for pending) - - This helps quickly identify which prerequisite tasks are blocking work -- `priority`: Importance level of the task (Example: `"high"`, `"medium"`, `"low"`) -- `details`: In-depth implementation instructions (Example: `"Use GitHub client ID/secret, handle callback, set session token."`) -- `testStrategy`: Verification approach (Example: `"Deploy and call endpoint to confirm 'Hello World' response."`) -- `subtasks`: List of smaller, more specific tasks that make up the main task (Example: `[{"id": 1, "title": "Configure OAuth", ...}]`) - -## Integrating with Cursor AI - -Claude Task Master is designed to work seamlessly with [Cursor AI](https://www.cursor.so/), providing a structured workflow for AI-driven development. - -### Setup with Cursor - -1. After initializing your project, open it in Cursor -2. The `.cursor/rules/dev_workflow.mdc` file is automatically loaded by Cursor, providing the AI with knowledge about the task management system -3. Place your PRD document in the `scripts/` directory (e.g., `scripts/prd.txt`) -4. Open Cursor's AI chat and switch to Agent mode - -### Initial Task Generation - -In Cursor's AI chat, instruct the agent to generate tasks from your PRD: - -``` -Please use the task-master parse-prd command to generate tasks from my PRD. The PRD is located at scripts/prd.txt. -``` - -The agent will execute: - -```bash -task-master parse-prd scripts/prd.txt -``` - -This will: - -- Parse your PRD document -- Generate a structured `tasks.json` file with tasks, dependencies, priorities, and test strategies -- The agent will understand this process due to the Cursor rules - -### Generate Individual Task Files - -Next, ask the agent to generate individual task files: - -``` -Please generate individual task files from tasks.json -``` - -The agent will execute: - -```bash -task-master generate -``` - -This creates individual task files in the `tasks/` directory (e.g., `task_001.txt`, `task_002.txt`), making it easier to reference specific tasks. - -## AI-Driven Development Workflow - -The Cursor agent is pre-configured (via the rules file) to follow this workflow: - -### 1. Task Discovery and Selection - -Ask the agent to list available tasks: - -``` -What tasks are available to work on next? -``` - -The agent will: - -- Run `task-master list` to see all tasks -- Run `task-master next` to determine the next task to work on -- Analyze dependencies to determine which tasks are ready to be worked on -- Prioritize tasks based on priority level and ID order -- Suggest the next task(s) to implement - -### 2. Task Implementation - -When implementing a task, the agent will: - -- Reference the task's details section for implementation specifics -- Consider dependencies on previous tasks -- Follow the project's coding standards -- Create appropriate tests based on the task's testStrategy - -You can ask: - -``` -Let's implement task 3. What does it involve? -``` - -### 3. Task Verification - -Before marking a task as complete, verify it according to: - -- The task's specified testStrategy -- Any automated tests in the codebase -- Manual verification if required - -### 4. Task Completion - -When a task is completed, tell the agent: - -``` -Task 3 is now complete. Please update its status. -``` - -The agent will execute: - -```bash -task-master set-status --id=3 --status=done -``` - -### 5. Handling Implementation Drift - -If during implementation, you discover that: - -- The current approach differs significantly from what was planned -- Future tasks need to be modified due to current implementation choices -- New dependencies or requirements have emerged - -Tell the agent: - -``` -We've changed our approach. We're now using Express instead of Fastify. Please update all future tasks to reflect this change. -``` - -The agent will execute: - -```bash -task-master update --from=4 --prompt="Now we are using Express instead of Fastify." -``` - -This will rewrite or re-scope subsequent tasks in tasks.json while preserving completed work. - -### 6. Breaking Down Complex Tasks - -For complex tasks that need more granularity: - -``` -Task 5 seems complex. Can you break it down into subtasks? -``` - -The agent will execute: - -```bash -task-master expand --id=5 --num=3 -``` - -You can provide additional context: - -``` -Please break down task 5 with a focus on security considerations. -``` - -The agent will execute: - -```bash -task-master expand --id=5 --prompt="Focus on security aspects" -``` - -You can also expand all pending tasks: - -``` -Please break down all pending tasks into subtasks. -``` - -The agent will execute: - -```bash -task-master expand --all -``` - -For research-backed subtask generation using Perplexity AI: - -``` -Please break down task 5 using research-backed generation. -``` - -The agent will execute: - -```bash -task-master expand --id=5 --research -``` - -## Command Reference - -Here's a comprehensive reference of all available commands: - -### Parse PRD - -```bash -# Parse a PRD file and generate tasks -task-master parse-prd - -# Limit the number of tasks generated -task-master parse-prd --num-tasks=10 -``` - -### List Tasks - -```bash -# List all tasks -task-master list - -# List tasks with a specific status -task-master list --status= - -# List tasks with subtasks -task-master list --with-subtasks - -# List tasks with a specific status and include subtasks -task-master list --status= --with-subtasks -``` - -### Show Next Task - -```bash -# Show the next task to work on based on dependencies and status -task-master next -``` - -### Show Specific Task - -```bash -# Show details of a specific task -task-master show -# or -task-master show --id= - -# View a specific subtask (e.g., subtask 2 of task 1) -task-master show 1.2 -``` - -### Update Tasks - -```bash -# Update tasks from a specific ID and provide context -task-master update --from= --prompt="" -``` +Unlike the `update-task` command which replaces task information, the `update-subtask` command *appends* new information to the existing subtask details, marking it with a timestamp. This is useful for iteratively enhancing subtasks while preserving the original content. ### Generate Task Files diff --git a/package.json b/package.json index b73e896e..e824a6ff 100644 --- a/package.json +++ b/package.json @@ -11,6 +11,7 @@ }, "scripts": { "test": "node --experimental-vm-modules node_modules/.bin/jest", + "test:fails": "node --experimental-vm-modules node_modules/.bin/jest --onlyFailures", "test:watch": "node --experimental-vm-modules node_modules/.bin/jest --watch", "test:coverage": "node --experimental-vm-modules node_modules/.bin/jest --coverage", "prepare-package": "node scripts/prepare-package.js", diff --git a/scripts/modules/ai-services.js b/scripts/modules/ai-services.js index cc3c49bc..4850fb97 100644 --- a/scripts/modules/ai-services.js +++ b/scripts/modules/ai-services.js @@ -44,6 +44,56 @@ function getPerplexityClient() { return perplexity; } +/** + * Get the best available AI model for a given operation + * @param {Object} options - Options for model selection + * @param {boolean} options.claudeOverloaded - Whether Claude is currently overloaded + * @param {boolean} options.requiresResearch - Whether the operation requires research capabilities + * @returns {Object} Selected model info with type and client + */ +function getAvailableAIModel(options = {}) { + const { claudeOverloaded = false, requiresResearch = false } = options; + + // First choice: Perplexity if research is required and it's available + if (requiresResearch && process.env.PERPLEXITY_API_KEY) { + try { + const client = getPerplexityClient(); + return { type: 'perplexity', client }; + } catch (error) { + log('warn', `Perplexity not available: ${error.message}`); + // Fall through to Claude + } + } + + // Second choice: Claude if not overloaded + if (!claudeOverloaded && process.env.ANTHROPIC_API_KEY) { + return { type: 'claude', client: anthropic }; + } + + // Third choice: Perplexity as Claude fallback (even if research not required) + if (process.env.PERPLEXITY_API_KEY) { + try { + const client = getPerplexityClient(); + log('info', 'Claude is overloaded, falling back to Perplexity'); + return { type: 'perplexity', client }; + } catch (error) { + log('warn', `Perplexity fallback not available: ${error.message}`); + // Fall through to Claude anyway with warning + } + } + + // Last resort: Use Claude even if overloaded (might fail) + if (process.env.ANTHROPIC_API_KEY) { + if (claudeOverloaded) { + log('warn', 'Claude is overloaded but no alternatives are available.
