Install a hook that blocks destructive git commands before an AI agent runs them. Use when an agent force-pushed or ran reset --hard, when adding git safety hooks, or when protecting main from agent pushes.
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
# Git Guardrails An agent with shell access can run `git reset --hard`, `git clean -fdx` or `git push --force` as casually as `ls`, usually while trying to make a failing command pass. This skill installs a **PreToolUse hook** that reads every Bash call before it runs, parses the git invocations inside it (chains, subshells, `bash -c`, `xargs`, `git -C`), and blocks the destructive ones with exit code 2 and a reason the agent can act on. It ships the hook, an installer that merges into `.claude/settings.json` without overwriting anything, plain git `pre-push` and `pre-rebase` hooks for non-agent callers, and a corpus tester that proves which commands are allowed and which are blocked. ## When to use this skill - **After an incident**: an agent discarded uncommitted work, deleted a branch, or force-pushed over a teammate's commits - **Before giving an agent autonomy**: auto-accept mode, background agents, long unattended runs, or several agents in parallel worktrees - **Protecting shared branches**: no direct pushes or rebases on `main`, `release/*`, `production` - **Auditing an existing guardrail**: run its hook against the corpus to see what it actually catches …

How to install
mdr add borghei/claude-skills/git-guardrails@sha256:5cc06d0a4e61102fThe 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.
