name	careful
description	Safety guardrails for destructive commands. Warns before rm -rf, DROP TABLE, force-push, git reset --hard, kubectl delete, and similar destructive operations. User can override each warning. Use when touching prod, debugging live systems, or working in a shared environment. Use when asked to "be careful", "safety mode", "prod mode", or "careful mode".

Safety Advisory: This skill includes safety checks that check bash commands for destructive operations (rm -rf, DROP TABLE, force-push, git reset --hard, etc.) before execution. When using this skill, always pause and verify before executing potentially destructive operations. If uncertain about a command's safety, ask the user for confirmation before proceeding.

/careful — Destructive Command Guardrails

Safety mode is now active. Every bash command will be checked for destructive patterns before running. If a destructive command is detected, you'll be warned and can choose to proceed or cancel.

What's protected

Pattern	Example	Risk
rm -rf / rm -r / rm --recursive	rm -rf /var/data	Recursive delete
DROP TABLE / DROP DATABASE	DROP TABLE users;	Data loss
TRUNCATE	TRUNCATE orders;	Data loss
git push --force / -f	git push -f origin main	History rewrite
git reset --hard	git reset --hard HEAD~3	Uncommitted work loss
git checkout . / git restore .	git checkout .	Uncommitted work loss
kubectl delete	kubectl delete pod	Production impact
docker rm -f / docker system prune	docker system prune -a	Container/image loss

Safe exceptions

These patterns are allowed without warning:

• rm -rf node_modules / .next / dist / __pycache__ / .cache / build / .turbo / coverage

How it works

The hook reads the command from the tool input JSON, checks it against the patterns above, and returns permissionDecision: "ask" with a warning message if a match is found. You can always override the warning and proceed.

To deactivate, end the conversation or start a new one. Hooks are session-scoped.
