gsd-map-codebase SKILL.md skillA
gsd-map-codebase from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add coco-research/coco/gsd-map-codebase@git:20260914.e75f220Pins git:20260914.e75f220 in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:d0f57f615bd10d2dThe line at the top of this page pins the label git:20260914.e75f220, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
