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.
Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them.
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.
Ask the user: install for () or ()?

Version history
.claude/settings.json~/.claude/settings.jsonThe bundled script is at: scripts/block-dangerous-git.sh
Copy it to the target location based on scope:
.claude/hooks/block-dangerous-git.sh~/.claude/hooks/block-dangerous-git.shMake it executable with chmod +x.
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.
Ask if user wants to add or remove any patterns from the blocked list. Edit the copied script accordingly.
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.
