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". (gstack)

/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.
