Skill Vetter#

Review third-party skills before installing them. Catch security risks early.

Quick Start#

bash

python3 scripts/vet.py --skill /path/to/skill
python3 scripts/vet.py --slug some-skill  # vet a ClawHub skill

What It Checks#

1. Permission scope — Does the skill request exec, network, or file access?
2. Suspicious patterns — eval(), exec(), subprocess, fetch to unknown hosts, encoded strings
3. Data exfiltration — Sending data to external endpoints, logging secrets
4. Dependency risks — Known vulnerable packages, excessive dependencies
5. Code quality — Minified/obfuscated code, missing SKILL.md, oversized files
6. Secret exposure — Hardcoded API keys, tokens, passwords in source

Risk Score#

Each check produces a risk score 0-100:

• 0-20: ✅ Safe — install freely
• 21-50: ⚠️ Caution — review findings before installing
• 51-75: 🚨 Risky — significant security concerns
• 76-100: ❌ Dangerous — do not install
