gsd-map-codebase skillA
gsd-map-codebase is agent-read markdown (skill) from coco-research/coco: Use when onboarding to an unfamiliar codebase, before a major refactor, on a brownfield project before /gsd-new-project, or to refresh .planning/codebase/. Spawns up to 4 parallel mapper agents that write 7 documents..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective> Analyze existing codebase using parallel gsd-codebase-mapper agents to produce structured codebase documents. Each mapper agent explores a focus area and **writes documents directly** to `.planning/codebase/`. The orchestrator only receives confirmations, keeping context usage minimal. Output: .planning/codebase/ folder with 7 structured documents about the codebase state. </objective> <execution_context> @$HOME/.claude/get-shit-done/workflows/map-codebase.md </execution_context> <context> Focus area: $ARGUMENTS (optional - if provided, tells agents to focus on specific subsystem) **Load project state if exists:** Check for .planning/STATE.md - loads context if project already initialized **This command can run:** - Before /gsd-new-project (brownfield codebases) - creates codebase map first - After /gsd-new-project (greenfield codebases) - updates codebase map as code evolves - Anytime to refresh codebase understanding </context> <when_to_use> **Use map-codebase for:** - Brownfield projects before initialization (understand existing code first) - Refreshing codebase map after significant changes - Onboarding to an unfamiliar codebase …

How to install
mdr add coco-research/coco/gsd-map-codebase@git:20260914.e75f220mdr add coco-research/coco/gsd-map-codebase@sha256:d0f57f615bd10d2dPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
