Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.

What this skill does
Setup Git Guardrails Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them. What Gets Blocked git push (all variants including --force) git reset --hard git clean -f / git clean -fd git branch -D git checkout . / git restore . When blocked, Claude sees a message telling it that it does not have authority to access these commands. Steps 1. Ask scope Ask the user: install for this project only (.claude/settings.json) or all projects (~/.claude/settings.json)? 2. Copy the hook script The bundled script is at: scripts/block-dangerous-git.sh Copy it to the target location based on scope: Project: .claude/hooks/block-dangerous-git.sh Global: ~/.claude/hooks/block-dangerous-git.sh Make it executable with chmod +x. 3. Add hook to settings Add to the appropriate settings file: Project (.claude/settings.json): Global (~/.claude/settings.json): If the settings file already exists, merge the hook into existing hooks.PreToolUse array — don't overwrite other settings. 4. Ask about customization Ask if user wants to add or remove any patterns from the blocked list. Edit the copied script accordingly. 5. Verify Run a quick test: Should exit with code 2 and print a BLOCKED message to stderr.
How to use it
