INTEGRATION NOTE: Extracted from gstack and renamed gs-careful (Phase 1B) to coexist with the host environment's CARL routing. Original gstack docs follow. Sibling gstack skills referenced below map to gs-* when installed (the 19-skill set); gstack-only infra (browse binary, gstack bin/ toolchain, ~/.gstack GBrain) is not installed here, so dependent steps degrade gracefully.
When to invoke this skill
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".
/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.
