/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.
mkdir -p ~/.gstack/analytics
echo '{"skill":"careful","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
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.
