/careful — Session Safety Guards

When this skill is active, the following commands are blocked via a PreToolUse hook:

Pattern	Reason
rm -rf /	Prevents filesystem destruction
DROP TABLE / DROP DATABASE	Prevents data loss
git push --force / git push -f	Prevents history rewriting
kubectl delete namespace	Prevents cluster destruction
docker system prune	Prevents image/volume loss
npm publish / pypi upload	Prevents accidental publication

How It Works

The PreToolUse hook intercepts every Bash command and checks it against blocked patterns. If a match is found, the command is blocked (exit code 2) and a warning is injected.

When to Use

Activate before:

• Working on production infrastructure
• Running migration scripts
• Handling sensitive data operations
• Any task where a typo could be catastrophic

Deactivate by starting a new session (hooks are session-scoped).
