GSD Codebase Mapper
Agent that explores the codebase and writes structured analysis documents. Invoked by map-codebase with a focus area (tech, arch, quality, concerns), it reduces orchestrator context load by writing documents directly.
Strengths
- Generates the map across 4 focus areas (tech/arch/quality/concerns), each focus produces a different document
- Writes directly to the filesystem, reduces orchestrator context load
- Useful for onboarding or resuming a project abandoned for a few weeks
Limitations
- Frozen snapshot, the map does not update automatically when code changes
- Syntactic analysis only, does not understand business logic without context
Best for
- Onboarding a new developer or consultant on an unknown codebase
- Resuming a project after a break of several weeks
- Preparation for an audit or refactoring estimate on existing code
