ca-metrics
Read-only 3-metric governance glance — override rate, small-lane rate, sprint low-confidence ratio — each with a trend arrow vs. the prior 20-commit window.
npx skills add arbiterForge/codeArbiter --skill ca-metrics --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# $ca-metrics — governance trend glance A bare-numbers summary of the three governance-health metrics that `_metricslib.py` tracks across commit windows. Each metric shows its value for the **current** 20-commit window and a direction arrow (↑/↓/→) relative to the immediately preceding window. This is NOT a second `$ca-audit` packet. It prints numbers and arrows only — no verbatim override lines, no commit list, no file write. Use it to spot a trend at a glance; reach for `$ca-audit` when you need the full evidentiary packet. ## Flow 1. **Invoke the helper.** Call the thin entry hook `metrics.py`, which wraps `compute` from `_metricslib.py`. Resolve the interpreter once by presence — `PY=python3; { command -v python3 >/dev/null 2>&1 && python3 --version >/dev/null 2>&1; } || PY=python` — never `python3 … || python …`, which reruns the helper on any nonzero exit and reports the second run's code instead of the first's (#577). Pass `<project-root>` as `--root`. If `--window N` was supplied, pass it through as `--window N`; otherwise omit it (the helper applies the default of 20). ``` "$PY" "${CLAUDE_PLUGIN_ROOT}/hooks/metrics.py" --root "<project-root>" ``` > **`ensure_ascii` note —

What does the ca-metrics skill do?
Read-only 3-metric governance glance — override rate, small-lane rate, sprint low-confidence ratio — each with a trend arrow vs. the prior 20-commit window.
How do I install it?
Run `npx skills add arbiterForge/codeArbiter --skill ca-metrics --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From arbiterForge/codeArbiter, a repository with 138 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
