safety-guard
GitHub通过拦截危险命令和限制文件编辑范围，防止生产环境误操作。提供谨慎、冻结及组合三种保护模式，适用于自主代理运行或敏感操作场景，保障系统安全。

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 tool calls. Checks the command/path against the active rules before allowing execution.
Integration
- Enable by default for
codex -a neversessions - Pair with observability risk scoring in ECC 2.0
- Logs all blocked actions to
~/.claude/safety-guard.log
