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 never sessions
  • Pair with observability risk scoring in ECC 2.0
  • Logs all blocked actions to ~/.claude/safety-guard.log
