Skill Trust Auditor

Audit any ClawHub skill for security risks before installation. Produces a Trust Score (0-100) and flags dangerous patterns. Created in response to the ClawHavoc incident (Feb 2026, 341 malicious skills).

Setup (first run only)

bash scripts/setup.sh

Audit a Skill

When user says "audit [skill-name]" or "is [skill-name] safe" or before any clawhub install:

bash scripts/audit.sh [skill-name-or-url]
# Example:
bash scripts/audit.sh steipete/clawhub
bash scripts/audit.sh https://clawhub.ai/someuser/someskill

Output:

{
  "skill": "someuser/someskill",
  "trust_score": 72,
  "verdict": "INSTALL WITH CAUTION",
  "risks": [
    {"level": "HIGH", "pattern": "curl to external domain", "location": "scripts/sync.sh:14"},
    {"level": "MEDIUM", "pattern": "reads MEMORY.md", "location": "SKILL.md:23"}
  ],
  "safe_patterns": ["no env var access", "no self-modification"],
  "author_verified": false,
  "recommendation": "Review scripts/sync.sh:14 before installing. The external curl call could exfiltrate data."
}

Post to user with clear summary:

🛡️ Trust Audit: someuser/someskill
Score: 72/100 — ⚠️ INSTALL WITH CAUTION

🔴 HIGH: curl to unknown domain in scripts/sync.sh:14
🟡 MEDIUM: reads your MEMORY.md

Recommendation: Inspect line 14 of sync.sh before proceeding.
Run: clawhub show someuser/someskill --file scripts/sync.sh

Trust Score Guide

Score	Verdict	Action
90-100	✅ SAFE	Install freely
70-89	⚠️ CAUTION	Review flagged items first
50-69	🟠 RISKY	Only if you understand the risks
0-49	🔴 DO NOT INSTALL	High probability of malicious intent

Risk Pattern Reference

HIGH RISK (-30 each):

• process.env access in scripts
• curl/wget to non-standard domains
• Reading ~/.config or ~/.openclaw directly
• exec() with user-controlled input
• Instructions to modify SOUL.md/AGENTS.md/openclaw.json

MEDIUM RISK (-10 each):

• Any outbound API calls (even to known services)
• File writes outside workspace
• Reading MEMORY.md or diary files

LOW RISK (-3 each):

• web_fetch to standard domains
• Read-only file access in workspace

Auto-Audit Mode

Optionally prepend audit to every install:

# Add to your shell aliases:
alias clawhub-safe='bash ~/.openclaw/workspace/skills/skill-trust-auditor/scripts/audit.sh $1 && clawhub install $1'
