Skill Security Auditor

Skill Verified Active

Security audit and vulnerability scanner for AI agent skills before installation. Use when: (1) evaluating a skill from an untrusted source, (2) auditing a skill directory or git repo URL for malicious code, (3) pre-install security gate for Claude Code plugins, OpenClaw skills, or Codex skills, (4) scanning Python scripts for dangerous patterns like os.system, eval, subprocess, network exfiltration, (5) detecting prompt injection in SKILL.md files, (6) checking dependency supply chain risks, (7) verifying file system access stays within skill boundaries. Triggers: "audit this skill", "is this skill safe", "scan skill for security", "check skill before install", "skill security check", "skill vulnerability scan".

Purpose

To ensure the safety and integrity of AI agent skills by providing a thorough security audit before installation, mitigating risks from malicious code or vulnerabilities.

Features

  • Scans Python, Bash, JS, and Markdown files
  • Detects command injection, code execution, obfuscation
  • Identifies prompt injection, data exfiltration, privilege escalation
  • Checks dependency supply chain risks and filesystem abuse
  • Outputs clear PASS/WARN/FAIL verdicts with remediation

Use Cases

  • Auditing skills from untrusted sources
  • Scanning AI agent directories or git repo URLs for malicious code
  • Acting as a pre-install security gate for skills
  • Verifying file system access stays within skill boundaries

Non-Goals

  • Executing the skill's code (static analysis only)
  • Detecting logic bombs or time-delayed payloads
  • Guaranteeing 100% detection against novel obfuscation techniques
