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",
"command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh"
}
]
}
]
}
}Global (~/.claude/settings.json):
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
"command": "~/.claude/hooks/block-dangerous-git.sh"
}
]
}
]
}
}If the settings file already exists, merge the hook into the 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:
echo '{"tool_input":{"command":"git push origin main"}}' | <path-to-script>Should exit with code 2 and print a BLOCKED message to stderr.
