# debt-ops-metrics Read the hidden metrics log and tell the user whether the tripwires are tripping. ## 1. Find the log The repo-hash is computed in Python (not `shasum`) so this is identical across macOS, Linux, and Windows — no BSD/GNU coreutils dependency. ```bash REPO_HASH=$(python3 -c "import hashlib,subprocess;t=subprocess.run(['git','rev-parse','--show-toplevel'],capture_output=True,text=True).stdout.strip();print(hashlib.sha1(t.encode()).hexdigest()[:12] if t else '')") # Hooks and skills share one deterministic cache base. Override with # DEBT_OPS_CACHE; default is ~/.cache/debt-ops. CACHE_DIR="${DEBT_OPS_CACHE:-$HOME/.cache/debt-ops}/cache/$REPO_HASH" LOG="$CACHE_DIR/metrics.jsonl" if [ -n "$REPO_HASH" ] && [ -f "$LOG" ]; then tail -n 500 "$LOG" else echo "MISSING: no metrics.jsonl found for repo hash ${REPO_HASH:-<not-a-git-repo>}" fi ``` If the file is missing or empty, tell the user no debt-ops activity has been logged for this repo yet and stop. On a skills-only tool (no hook adapter), only `register` and `review` events are logged — the per-edit `edit`/`feedback`/`session` events come from the hook adapter, so feedback metrics will be absent. Say so rather than reporting them as zero. ## 2. The log format One JSON object per line. Event shapes: - `{"event":"register","slug":"...","ai_authored":bool,"letter":"...","ts":"..."}` — each capture - `{"event":"review","total":N,"stale":N,"cold":N,"active":N,"ts":"..."}` — each review - `{"event":"edit","
