Phase 4 / Ep 22: Skill Security Audit — Essential Preparations Before Installing ClawHub

🎯 Learning Objective: Establish security review awareness and methodologies for third-party Skills.

1. Why is Auditing Necessary?

The scripts directory of a Skill may contain arbitrary executable code. If your Agent has coding or full permissions, a malicious Skill could:

• Steal your API Keys
• Read and upload private files
• Install backdoor programs
• Consume massive amounts of LLM tokens

2. Audit Checklist

✅ SKILL.md Check

Check Item	🟢 Safe Signal	🔴 Danger Signal
Permission Declaration	Explicitly declares required permissions	Requests full permissions but has simple functionality
Clear Description	Specific and clear functional description	Vague description, unclear functionality
Version Number	Follows SemVer	Chaotic version numbering
Author Information	Traceable author identity	Published anonymously

✅ scripts/ Directory Check

• Does the code contain curl requests to unknown servers?
• Does it read ~/.openclaw/openclaw.json (contains sensitive configurations)?
• Does it contain eval or dynamic code execution?
• Does it modify files outside the working directory?

✅ Permission Declaration vs. Actual Behavior

Declares only needing basic permissions, but the script contains rm -rf? Reject the installation immediately.

3. Enterprise Environment Security Policies

# Set Skill whitelist mode
openclaw config set skills.installMode whitelist
openclaw config set skills.allowedSources ["openclaw/*", "verified/*"]

4. Security Audit Commands

# Preview Skill content before installation
openclaw skills preview web-search

# Inspect the script source code of a Skill
openclaw skills inspect web-search --scripts
