Skill Vetter

Skill Vetter 🔒

Security-first vetting protocol for AI agent skills. Never install a skill without vetting it first.

When to Use

Before installing any skill from ClawdHub Before running skills from GitHub repos When evaluating skills shared by other agents Anytime you're asked to install unknown code

Step 1: Source Check

• Questions to answer:
• [ ] Where did this skill come from?
• [ ] Is the author known/reputable?
• [ ] How many downloads/stars does it have?
• [ ] When was it last updated?
• [ ] Are there reviews from other agents?

Step 2: Code Review (MANDATORY)

Read ALL files in the skill. Check for these RED FLAGS: 🚨 REJECT IMMEDIATELY IF YOU SEE: ───────────────────────────────────────── • curl/wget to unknown URLs • Sends data to external servers • Requests credentials/tokens/API keys • Reads ~/.ssh, ~/.aws, ~/.config without clear reason • Accesses MEMORY.md, USER.md, SOUL.md, IDENTITY.md • Uses base64 decode on anything • Uses eval() or exec() with external input • Modifies system files outside workspace • Installs packages without listing them • Network calls to IPs instead of domains • Obfuscated code (compressed, encoded, minified) • Requests elevated/sudo permissions • Accesses browser cookies/sessions • Touches credential files ─────────────────────────────────────────

Step 3: Permission Scope

• Evaluate:
• [ ] What files does it need to read?
• [ ] What files does it need to write?
• [ ] What commands does it run?
• [ ] Does it need network access? To where?
• [ ] Is the scope minimal for its stated purpose?

Step 4: Risk Classification

Output Format

After vetting, produce this report: SKILL VETTING REPORT ═══════════════════════════════════════ Skill: [name] Source: [ClawdHub / GitHub / other] Author: [username] Version: [version] ─────────────────────────────────────── METRICS: • Downloads/Stars: [count] • Last Updated: [date] • Files Reviewed: [count] ─────────────────────────────────────── RED FLAGS: [None / List them] PERMISSIONS NEEDED: • Files: [list or "None"] • Network: [list or "None"] • Commands: [list or "None"] ─────────────────────────────────────── RISK LEVEL: [🟢 LOW / 🟡 MEDIUM / 🔴 HIGH / ⛔ EXTREME] VERDICT: [✅ SAFE TO INSTALL / ⚠️ INSTALL WITH CAUTION / ❌ DO NOT INSTALL] NOTES: [Any observations] ═══════════════════════════════════════

Quick Vet Commands

For GitHub-hosted skills: # Check repo stats curl -s "https://api.github.com/repos/OWNER/REPO" | jq '{stars: .stargazers_count, forks: .forks_count, updated: .updated_at}' # List skill files curl -s "https://api.github.com/repos/OWNER/REPO/contents/skills/SKILL_NAME" | jq '.[].name' # Fetch and review SKILL.md curl -s "https://raw.githubusercontent.com/OWNER/REPO/main/skills/SKILL_NAME/SKILL.md"

Trust Hierarchy

Official OpenClaw skills → Lower scrutiny (still review) High-star repos (1000+) → Moderate scrutiny Known authors → Moderate scrutiny New/unknown sources → Maximum scrutiny Skills requesting credentials → Human approval always

Remember

No skill is worth compromising security When in doubt, don't install Ask your human for high-risk decisions Document what you vet for future reference Paranoia is a feature. 🔒🦀
