Commit-time protection: blocks credentials, private keys and credential files in every repo, and unapproved disclosures where outsiders read it (class read from push remotes, with a disclosure ledger). Use to install, configure or debug the commit check, or when a commit is refused.
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
# Synthesis Git Hooks One global `core.hooksPath` sends git's pre-commit, pre-merge-commit and commit-msg hooks in every repository on the machine through `synthesis/commit_check.py`. It refuses credentials everywhere, refuses unapproved disclosures where outsiders read the repository, refuses commits into another session's claim, and then runs the repository's own hooks. The rules live in code that runs outside the model, so they hold under load. ## Binding rules 1. **Fail closed.** A policy, ledger, board or diff the check can't read with certainty blocks the commit and says why. Protection that fails open manufactures false confidence (2026-07-28: commits passed unscanned when one interpreter lacked a YAML package). 2. **Never `git commit --no-verify`** without the principal's explicit approval for that commit, and **never reword, split, encode or build a flagged term at run time to get past the check.** No word list can tell a leak from a legitimate mention; disguising the text weakens it and defeats the check (ruling of 2026-10-06). Remove a leak; get a legitimate line approved. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-git-hooks@sha256:d65e3ac089d67468The line at the top of this page pins the label v3.2.0, 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.
