This loads architecture, testing, and debugging docs for the Astro monorepo based on what you're actually doing. It's context loading, not workflow orchestration. You get a decision matrix that maps tasks like "fixing a bug" or "adding a core feature" to specific markdown files, plus critical warnings about common pitfalls like Node.js API restrictions in runtime code and test isolation requirements. The quick command reference and file path guide are solid. Worth noting it explicitly tells you when not to use it, which is refreshing. If you're contributing to Astro core or debugging build pipeline issues, this beats hunting through scattered docs. For casual Astro usage, skip it.
