SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents the installation or use of malicious or risky third-party agent skills by performing a comprehensive static security audit and producing a clear verdict and remediation guidance before execution.

Core Features & Use Cases

  • File Inventory & Mapping: Enumerates SKILL.md, scripts, references, assets, and manifests to create a complete inspection surface.
  • Static Analysis & Risk Scoring: Detects prompt injection, role hijacking, data exfiltration patterns, SSRF, dangerous filesystem access, obfuscation, and risky dependency configurations and maps findings to severity and OWASP categories.
  • Actionable Report Template: Produces a structured audit report with evidence, severity, OWASP category mapping, and explicit install recommendation for developers and non-expert users.
  • Use Case: Run when a user pastes a skill repo URL, requests installation of an external skill, or asks "is this skill safe?" to decide whether to install, require fixes, or reject the skill.

Quick Start

Use the skill-security-analyzer to audit the skill at path .agents/.skills/incoming-skill and generate a full security audit report.

FAQPage Schema
How do I audit a VS Code agent skill for security risks before installing it?

To audit a skill for security risks before installation, you can run a static analysis on the skill files and manifests to detect vulnerabilities like prompt injection and SSRF, producing a structured report with severity mappings and remediation guidance.

What security vulnerabilities are detected during a static skill audit?

A static skill audit detects prompt injection, role hijacking, data exfiltration patterns, SSRF, dangerous filesystem access, obfuscation, and risky dependency configurations, mapping each finding to severity levels and OWASP categories.

Can I inspect remote skill repositories for malicious code without executing scripts?

Yes, you can inspect remote skill repositories for malicious code without executing scripts by performing a static analysis of files and manifests, preventing any skill scripts from running or fetching remote resources during the audit.

How do I check if a third-party skill has unsafe filesystem access or obfuscation?

You check for unsafe filesystem access or obfuscation in a third-party skill by enumerating its files, scripts, and manifests to map the inspection surface, then applying static analysis to identify risky patterns and generate an actionable report.

Does a pre-install skill audit provide an explicit recommendation on whether to install?

Yes, a pre-install skill audit produces an actionable report template that includes an explicit install recommendation based on the structured findings, evidence, severity, and OWASP category mappings to help you decide whether to install, require fixes, or reject the skill.

What is the best way to analyze external agent skills for data exfiltration patterns?

The best way to analyze external agent skills for data exfiltration patterns is to perform a comprehensive static audit on the local skill folder or repository, avoiding execution and generating a clear verdict with remediation guidance before use.
