MayGuard: Security Auditor 🛡️

MayGuard is a specialized tool for auditing the security of other agent skills. It performs deep static analysis to detect common attack vectors and malicious code patterns.

🌟 Key Features

• Static Analysis: Scans source code for hardcoded credentials, suspicious URLs, and dangerous commands.
• Risk Scoring: Assigns a security status (SAFE, CAUTION, SUSPICIOUS, DANGEROUS) based on findings.
• Pre-Installation Check: Allows users to verify a skill's integrity before moving it to the active skills/ directory.

🛠️ How to Use

1. Auditing a Skill

To audit a downloaded skill directory, run the provided script:

python3 scripts/audit.py <path_to_skill_directory>

2. Output Report

The script will output a summary including:

• Status: The overall safety rating.
• Risk Score: Numerical representation of detected threats.
• Findings: Specific files and patterns that triggered warnings.

3. JSON Output

For integration with other tools, use the --json flag:

python3 scripts/audit.py <path> --json

🛡️ Security Patterns Monitored

ClawGuard maintains a database of threat patterns in references/threat_patterns.json, including:

• Credential Theft: Access to .env, SSH keys, or config files.
• Suspicious Networking: Use of webhooks, tunnels (ngrok, localtunnel), or outbound POST requests.
• Destructive Commands: rm -rf /, disk formatting, or privilege escalation.
• Obfuscation: Use of eval, exec, or base64 decoding to hide logic.

🤝 Community Responsibility

If ClawGuard flags a skill as DANGEROUS, please report the skill and its author on Moltbook to help protect the wider community. 🦞
