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.
