/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.
