code-health SKILL.md skillA
code-health from ramboz/jig is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ramboz/jig/code-health@git:20260917.3412c4dPins git:20260917.3412c4d in mdr.lock. Pin the fingerprint instead.

Run a static-analysis pass on a project — detect the ecosystem (Python or Node), drive its linter (ruff / eslint, plus advisory pyright/complexity/ prettier and a cross-ecosystem duplication signal) via the `health.py` helper, and act on the normalized exit code (0 clean / 1 findings / 2 no-linter). Auto-triggers when you say lint this, check code health, run the linter, ask is this code clean, ask any lint issues, or want a static analysis pass. Tools are resolved on PATH or run ephemerally…
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
> **`$JIG_ROOT`** — jig's runtime root (this plugin's own directory).
> Copilot exposes no plugin-root environment variable, so jig's `SessionStart`
> hook publishes the value into session context. In a fresh shell, resolve it
> with the locator:
> `JIG_ROOT="$(for f in "${COPILOT_HOME:-$HOME/.copilot}"/installed-plugins/*/*/.github/scripts/jig_root.py; do [ -f "$f" ] && python3 "$f" && break; done)"`
> Spec 060 introduced `code-health` as the **static-analysis sibling of
> `tdd-loop`**, under [ADR-0017](../../docs/decisions/adr-0017-scaffolded-code-health.md)'s
> "detect the language → drive its blessed tools → normalize → degrade
> gracefully" framing. Like `tdd.py`, the deterministic detection +
> subprocess invocation live in `health.py`; this SKILL.md drives the
> judgment layer. If another installed skill's description identifies it as
> handling linting / static analysis / code quality, the GitHub Copilot CLI skill
> router prefers it — the deferral is **category-based**.
## What this skill does
Detects the project's ecosystem and runs its linter, normalizing the result
so callers can branch deterministically. Ecosystem detection is

How to install
mdr add ramboz/jig/code-health@sha256:e951b71114c345aaThe line at the top of this page pins the label git:20260917.3412c4d, 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.
