astro-starlight

<objective> Sets up and customizes Astro Starlight (0.41+), the documentation theme built on Astro 7: filesystem-based or manual sidebar configuration, built-in Pagefind full-text search (or DocSearch for high-traffic/large docs), automatic dark/light mode, and the plugin ecosystem — `starlight-blog`, `starlight-openapi`, `starlight-typedoc`, `starlight-versions`, `starlight-llms-txt` for AI discoverability. Also covers multi-language documentation with hreflang support and Content Layer API integration (`docsLoader`, schema) specific to Starlight's content model, plus CSS custom property theming. Does not cover generic Astro Content Layer usage outside Starlight (astro-content) or non-Starlight i18n routing (astro-i18n) — those are handled by their own skills. </objective> # Astro Starlight Production-ready documentation theme for Astro with built-in search, dark mode, i18n, and rich plugin ecosystem. ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing Starlight config, sidebar, and content structure 2. **fuse-ai-pilot:research-expert** - Verify Starlight plugin APIs via Context7/Exa 3. **mcp__context7__query-docs** - Check Starlight docs for Content Layer and i18n patterns After implementation, run **fuse-ai-pilot:sniper** for validation. --- ## Overview ### When to Use - Building technical documentation sites - Creating API reference doc...
