SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill acts as a crucial security layer, scanning AI agent skills for hidden threats like credential theft, code injection, and prompt manipulation before they are installed or executed.

Core Features & Use Cases

  • Multi-Layered Analysis: Employs pattern matching, AST analysis for evasion techniques, and advanced prompt injection detection.
  • Comprehensive Threat Coverage: Catches a wide range of vulnerabilities including code execution, data exfiltration, persistence mechanisms, and sophisticated prompt attacks.
  • Use Case: Before installing a new skill from an untrusted source, run SkillGuard to get a security score and detailed report, ensuring your agent remains safe and secure.

Quick Start

Use the skillguard skill to scan the local directory '/path/to/skill' for security vulnerabilities.

Frequently Asked Questions about skillguard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I scan an AI agent skill for security vulnerabilities before installing it?

You can scan an AI agent skill for security vulnerabilities by running a three-layer analysis engine against the local directory, ClawHub skill, or arbitrary text content to detect credential theft, code injection, and prompt manipulation.

What types of security threats can be detected during an AI skill audit?

An AI skill audit can detect credential theft, code injection, prompt manipulation, data exfiltration, persistence mechanisms, and evasion techniques using a three-layer analysis engine that includes pattern matching and AST analysis.

Do I need Node.js to run a security audit on local skill directories?

Yes, you need Node.js installed in your environment to execute the security audit on local skill directories, as the vulnerability scanning engine requires the Node.js runtime to perform its three-layer analysis.

Can I analyze arbitrary text content for prompt manipulation and data exfiltration threats?

Yes, you can analyze arbitrary text content for prompt manipulation and data exfiltration threats, alongside scanning local directories and ClawHub skills, to receive a comprehensive security score and detailed vulnerability report.

What is the best way to secure an AI agent from malicious skills downloaded from untrusted sources?

The best way to secure an AI agent from malicious skills is to run a vulnerability scan before installation, utilizing multi-layered analysis to catch code execution, evasion techniques, and prompt attacks, yielding a detailed security report.

Does SkillGuard detect evasion techniques used to hide malicious code in AI agent skills?

Yes, SkillGuard detects evasion techniques by employing AST analysis alongside pattern matching and advanced prompt injection detection to uncover hidden credential theft, code injection, and data exfiltration mechanisms in agent skills.
