Codebase Documenter
Turns a codebase into proper documentation so new developers aren't flying blind. It explores your project structure, traces execution paths, and generates markdown docs covering architecture, setup, data flow, and development guidelines. Uses the Explore agent to map everything out, then creates either a full docs folder or one comprehensive file. You get Mermaid diagrams, specific file references, and actual code examples pulled from your project. Takes 15 to 60 minutes depending on depth. Honestly most useful when onboarding people or inheriting a project with zero documentation, which is most projects.
