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
