Codebase Knowledge Builder
Studies unfamiliar repositories and produces evidence-backed, source-cited architecture documentation and onboarding artifacts.
Codebase Knowledge Builder accelerates developer onboarding and system orientation by systematically analyzing unfamiliar repositories through a rigorous four-phase methodology: reconnaissance, deep-dive tracing, artifact authoring, and validation. Operating under strict read-only and safety guardrails, it maps software architecture, core control flows, error paths, and system boundaries while rigorously citing source paths and line numbers. The skill differentiates between observed code reality and inferences, explicitly marks unknowns, and exports clean, revision-specific Markdown documentation complete with optional Mermaid diagrams to help engineering teams understand complex codebases safely and accurately.
