# Safety Guard — Prevent Destructive Operations ## When to Use - When working on production systems - When agents are running autonomously (full-auto mode) - When you want to restrict edits to a specific directory - During sensitive operations (migrations, deploys, data changes) ## How It Works Three modes of protection: ### Mode 1: Careful Mode Intercepts destructive commands before execution and warns: ``` Watched patterns: - rm -rf (especially /, ~, or project root) - git push --force - git reset --hard - git checkout . (discard all changes) - DROP TABLE / DROP DATABASE - docker system prune - kubectl delete - chmod 777 - sudo rm - npm publish (accidental publishes) - Any command with --no-verify ``` When detected: shows what the command does, asks for confirmation, suggests safer alternative. ### Mode 2: Freeze Mode Locks file edits to a specific directory tree: ``` /safety-guard freeze src/components/ ``` Any Write/Edit outside `src/components/` is blocked with an explanation. Useful when you want an agent to focus on one area without touching unrelated code. ### Mode 3: Guard Mode (Careful + Freeze combined) Both protections active. Maximum safety for autonomous agents. ``` /safety-guard guard --dir src/api/ --allow-read-all ``` Agents can read anything but only write to `src/api/`. Destructive commands are blocked everywhere. ### Unlock ``` /safety-guard off ``` ## Implementation Uses PreToolUse hooks to intercept Bash, Write, Edit, and MultiEdit to...
