Scans your codebase and generates ARCHITECTURE.md, API_ENDPOINTS.md, and DATABASE_SCHEMA.md based on what's actually there. It reads your source files, route definitions, schema, and config to figure out your stack, then writes structured docs that reflect the real implementation. Good for onboarding, post-refactor cleanups, or when you've been shipping features and the docs have gone stale. It detects project type automatically (Next.js, Hono, Cloudflare Workers, whatever) and only offers relevant docs. One thing I like: it diffs against existing docs and shows you what changed rather than silently overwriting your hand-written notes.
