Use before commit or push, or when asking if work is ready. Runs hygiene, changelog, and never-invent gates.

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

# Pre-Commit Check — Verification Before Every Push

Capability: prevent push until locally verifiable hygiene gates pass. No auto-fix — explicit confirmation.

## Trigger

Before git commit, commit --amend, gh pr create, or any push of series that ships.

## Gate checklist (all must PASS, no skip without reason)

1. Project discovery: CONTRIBUTING/HACKING/AGENTS.md found? Subject convention conventional commits? Trailer Signed-off-by/DCO? Recent git log -20 reviewed? If no guide, note inferred.
   ```bash
   ls CONTRIBUTING* .github/CONTRIBUTING* AGENTS.md 2>/dev/null; git log --oneline -20 | head
   ```

2. Factual integrity: every number/hash/claim sourced this session via file/cmd/benchmark? No plausible fill where TODO belongs? Evidence pasted verbatim?

3. Changelog subject ≤50 imperative present, problem first present in body, one idea per para, invariant not plumbing, public links only.
   ```bash
   head -n1 <<< "$(git log -1 --pretty=%B --no-merges)" | wc -c
   ```

How to install

The exact contents, by fingerprint
mdr add rikvanriel/code-hygiene/pre-commit-check@sha256:2087ece0d8edaa0a

The line at the top of this page pins the label v1.0.0, 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.
