* fix(build): use file glob instead of sidebar parsing for llms-full.txt

Replace brittle sidebar.js regex parsing with recursive file glob.
The old approach captured non-file strings like 'autogenerated' and
category labels, resulting in only 5 files being processed.

Now correctly processes all 86+ markdown files (~95k tokens).

* fix(seo): use absolute URLs in AI meta tags for agent discoverability

AI web-browsing agents couldn't follow relative paths in meta tags due to
URL security restrictions. Changed llms-full.txt and llms.txt meta tag
URLs from relative (baseUrl) to absolute (urlParts.origin + baseUrl).

* refactor(docs): recategorize misplaced files per Diataxis analysis

Phase 2.5 categorization fixes based on post-migration analysis:

Moved to correct Diataxis categories:
- tutorials/installation.md → deleted (duplicate of how-to/install-bmad.md)
- tutorials/brownfield-onboarding.md → how-to/brownfield/index.md
- reference/faq/* (8 files) → explanation/faq/
- reference/agents/barry-quick-flow.md → explanation/agents/
- reference/agents/bmgd-agents.md → explanation/game-dev/agents.md

Created:
- explanation/agents/index.md

Fixed all broken internal links (14 total)

* feat(docs): add Getting Started tutorial and simplify build script

- Add comprehensive Getting Started tutorial with installation as Step 1

* fix(css): use fixed width layout to prevent content shifting

Apply React Native docs approach: set both width and max-width at
largest breakpoint (1400px) so content area maintains consistent
size regardless of content length. Switches to fluid 100% below
1416px breakpoint.

* refactor(docs): migrate from Docusaurus to Astro+Starlight

Replace Docusaurus with Astro and the Starlight documentation theme
for improved performance, better customization, and modern tooling.

Build pipeline changes:
- New build-docs.js orchestrates link checking, artifact generation,
  and Astro build in sequence
- Add check-doc-links.js for validating internal links and anchors
- Generate llms.txt and llms-full.txt for LLM-friendly documentation
- Create downloadable source bundles (bmad-sources.zip, bmad-prompts.zip)
- Suppress MODULE_TYPELESS_PACKAGE_JSON warning in Astro build
- Output directly to build/site for cleaner deployment

Website architecture:
- Add rehype-markdown-links.js plugin to transform .md links to routes
- Add site-url.js helper for GitHub Pages URL resolution with strict
  validation (throws on invalid GITHUB_REPOSITORY format)
- Custom Astro components: Banner, Header, MobileMenuFooter
- Symlink docs/ into website/src/content/docs for Starlight

Documentation cleanup:
- Remove Docusaurus _category_.json files (Starlight uses frontmatter)
- Convert all docs to use YAML frontmatter with title field
- Move downloads.md from website/src/pages to docs/
- Consolidate style guide and workflow diagram docs
- Add 404.md and tutorials/index.md

title: "How to Create a Product Brief"
description: How to create a product brief using the BMad Method
---
Use the `product-brief` workflow to define product vision and strategy through an interactive process.
---
## When to Use This
- Starting new product or major feature initiative
- Aligning stakeholders before detailed planning
- Transitioning from exploration to strategy
- Need executive-level product documentation
---
## Prerequisites
- BMad Method installed
- Analyst agent available
- Optional: Research documents from previous workflows
---
## Steps
### 1. Load the Analyst Agent
Start a fresh chat and load the Analyst agent.
### 2. Run the Product Brief Workflow
```
*product-brief
```
### 3. Answer the Interactive Questions
The workflow guides you through strategic product vision definition:
- What problem are you solving?
- Who are your target users?
- What makes this solution different?
- What's the MVP scope?
### 4. Review and Refine
The agent will draft sections and let you refine them interactively.
---
## What You Get
The `product-brief.md` document includes:
- **Executive summary** - High-level overview
- **Problem statement** - With evidence
- **Proposed solution** - And differentiators
- **Target users** - Segmented
- **MVP scope** - Ruthlessly defined
- **Financial impact** - And ROI
- **Strategic alignment** - With business goals
- **Risks and open questions** - Documented upfront
---
## Integration with Other Workflows
The product brief feeds directly into the PRD workflow:
| Analysis Output | Planning Input |
|-----------------|----------------|
| product-brief.md | **prd** workflow |
| market-research.md | **prd** context |
| technical-research.md | **architecture** (Phase 3) |
Planning workflows automatically load the product brief if it exists.
---
## Common Patterns
### Greenfield Software (Full Analysis)
```
1. brainstorm-project - explore approaches
2. research (market/technical/domain) - validate viability
3. product-brief - capture strategic vision
4. → Phase 2: prd
```
### Skip Analysis (Clear Requirements)
```
→ Phase 2: prd or tech-spec directly
```
---
## Tips
- Be specific about the problem you're solving
- Ruthlessly prioritize MVP scope
- Document assumptions and risks
- Use research findings as evidence
- This is recommended for greenfield projects
