read-repo

Deep-analyze a local code repository and produce structured documentation: tech stack, languages, features, folder responsibilities, core architectural patterns, and generated markdown files (READREPO.md, ARCHITECTURE.md, etc.). Use when user wants to understand an unfamiliar codebase, document a project, analyze a repo, generate READREPO.md, or asks "what does this project do / how is it structured / how do I contribute / how do I take over".
