Summary
- Build a durable, navigable atlas of a code repository — structure, functional blocks, tech stack, history, CI/CD, strengths and weaknesses, and a "continue development" playbook — plus a distilled summary that bootstraps a future agent.
- Use when the user wants to understand, onboard to, document, take over, or keep building an unfamiliar codebase, asks for a repo overview / architecture map / codebase walkthrough, or wants to find good issues and PRs to contribute to a public repo.
