Database
DROP TABLEDROP DATABASETRUNCATE
Git
git push --force/git push -fgit reset --hardgit checkout -- ./git checkout .git clean -f

How It Works
PreToolUse hook on Bash tool. Parses command from stdin JSON, checks against dangerous patterns. Returns exit 2 (block) with warning message if matched, exit 0 (allow) otherwise.
Activation
The hook is registered in settings.json and always active. No /careful command needed to activate.
