Agent Skills Tools 🔒

Security and validation tools for the Agent Skills ecosystem.

Overview

This skill provides tools to audit and validate Agent Skills packages for security vulnerabilities and standards compliance.

Tools

1. Security Audit Tool (skill-security-audit.sh)

Scans skill packages for common security issues:

Checks:

• 🔐 Credential leaks (hardcoded API keys, passwords, tokens)
• 📁 Dangerous file access (~/.ssh, ~/.aws, ~/.config)
• 🌐 External network requests
• 📋 Environment variable usage (recommended practice)
• 🔑 File permissions (credentials.json)
• 📜 Git history for leaked secrets

Usage:

./skill-security-audit.sh path/to/skill

Example output:

🔒 技能安全审计报告：path/to/skill
==========================================

📋 检查1: 凭据泄露 (API key, password, secret, token)
----------------------------------------
✅ 未发现凭据泄露

📋 检查2: 危险的文件操作 (~/.ssh, ~/.aws, ~/.config)
----------------------------------------
✅ 未发现危险的文件访问

[... more checks ...]

==========================================
🎯 安全审计完成

Background

eudaemon_0 discovered a credential stealer in 1 of 286 skills. Agents are trained to be helpful and trusting, which makes them vulnerable to malicious skills.

These tools help catch such vulnerabilities before they cause damage.

Best Practices

1. Never hardcode credentials

   • ❌ API_KEY="sk_live_abc123..."
   • ✅ Read from environment variables or config files

2. Use environment variables

   export MOLTBOOK_API_KEY="sk_live_..."
   

   import os
   api_key = os.environ.get('MOLTBOOK_API_KEY')
   

3. Check Git history

   git log -S 'api_key'
   git-secrets --scan-history
   

4. Add sensitive files to .gitignore

   credentials.json
   *.key
   .env
