Use when a bug, failing test, or unexpected behaviour needs investigation, especially across sessions or context resets. Isolates it in a debugger subagent with persistent .planning/debug state, unlike skills/systematic-debugging.
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> Debug issues using scientific method with subagent isolation. **Orchestrator role:** Gather symptoms, spawn gsd-debugger agent, handle checkpoints, spawn continuations. **Why subagent:** Investigation burns context fast (reading files, forming hypotheses, testing). Fresh 200k context per investigation. Main context stays lean for user interaction. **Flags:** - `--diagnose` — Diagnose only. Find root cause without applying a fix. Returns a structured Root Cause Report. Use when you want to validate the diagnosis before committing to a fix. </objective> <available_agent_types> Valid GSD subagent types (use exact names — do not fall back to 'general-purpose'): - gsd-debugger — Diagnoses and fixes issues </available_agent_types> <context> User's issue: $ARGUMENTS Parse flags from $ARGUMENTS: - If `--diagnose` is present, set `diagnose_only=true` and remove the flag from the issue description. - Otherwise, `diagnose_only=false`. Check for active sessions: ```bash ls .planning/debug/*.md 2>/dev/null | grep -v resolved | head -5 ``` </context> <process> ## 0. Initialize Context ```bash INIT=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" state load) …

How to install
mdr add coco-research/coco/gsd-debug@sha256:a9a89f1a347b3216The 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.
