Blocks destructive commands like rm -rf, git --force, DROP TABLE, docker prune, and restricts file edits to specified directories. Use on production systems and with autonomous agents.

- When working on production systems
Enforces C++ Core Guidelines for writing, reviewing, and refactoring modern C++ code (C++17+), promoting RAII, immutability, type safety, and idiomatic practices.
Provides patterns for shared UI in Compose Multiplatform across Android, iOS, Desktop, and Web: state management with ViewModels/StateFlow, navigation, theming, and performance.
Implements Playwright E2E testing patterns: Page Object Model, test organization, configuration, reporters, artifacts, and CI/CD integration for stable suites.
Three modes of protection:
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.
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.
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.
/safety-guard off
Uses PreToolUse hooks to intercept Bash, Write, Edit, and MultiEdit tool calls. Checks the command/path against the active rules before allowing execution.
