description: 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 or add git safety guardrails.

Git Safety Hooks

Sets up PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them.

Blocked Commands

  • •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 message that it doesn't have authority to run these commands.

Installation

1. Ask Scope

Ask user: install for this project (.claude/settings.json) or all projects (~/.claude/settings.json)?

2. Copy Hook Script

From: scripts/block-dangerous-git.sh

To:

  • •Project: .claude/hooks/block-dangerous-git.sh
  • •Global: ~/.claude/hooks/block-dangerous-git.sh

Make executable: chmod +x <path>

3. Add to Settings

See configuration.md for settings JSON examples

4. Verify

Test by asking Claude to run git push - should be blocked

Customization

Edit blocked commands list in hook script.
