How do I install the Safety Guard skill?

Run npx skillmds add rajanthar/safety-guard in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Safety Guard safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Safety Guard?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Safety Guard free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

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
