Codebase Onboarding Guide Generator

Generates comprehensive internal developer onboarding documentation by scanning a codebase. Produces architecture overviews, directory maps, key file guides, environment variable docs, common task walkthroughs, and tribal knowledge sections. Gets new team members productive in hours instead of weeks.

Unlike a README (the project public face), this generates the internal tribal knowledge that usually lives in senior developers heads — the stuff that takes months to absorb by osmosis.

Works with any stack: Next.js, Django, Rails, Go, Rust, Java, Python, monorepos, microservices. No API keys or external services required — just point it at a repo.

Perfect for: onboarding new hires, inheriting undocumented codebases, contractor handoffs, pre-refactor audits, or documenting your own project after a long break.
