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.
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 --hardgit clean -f/git clean -fdgit branch -Dgit 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):
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
$install
