SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Installing third-party or unreviewed AI skills can introduce hidden risks like data exfiltration, prompt injection, credential exposure, and malicious scripts. This Skill performs a systematic security review of any skill package so you can identify threats before deployment. ## Core Features & Use Cases - Systematic Security Analysis: Reviews SKILL.md instructions, scripts, references, and assets against a catalog of known security patterns and anti-patterns. - Severity-Rated Findings: Produces an executive summary, CRITICAL/HIGH/MEDIUM/LOW findings list, and a 10-point security checklist covering data exfiltration, network access, prompt injection, and more. - .skill Package Support: Extracts and audits packaged .skill files, with heightened scrutiny for third-party skills of unknown provenance. - Use Case: Before installing a community-built skill, run this audit to detect undisclosed network calls, hardcoded credentials, obfuscated code, or instruction-override attempts. ## Quick Start Analyze the security of this skill package and report any vulnerabilities with severity ratings.

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

FAQPage Schema
How do I audit a Claude skill for security risks?▼

Provide the skill directory or .skill file and request a security analysis. The audit reviews SKILL.md instructions, scripts, references, and assets against known security patterns, then returns severity-rated findings and a checklist.

What security risks can a malicious AI skill contain?▼

Common risks include data exfiltration to undisclosed endpoints, prompt injection, hardcoded credentials, obfuscated code using base64 or eval, dangerous subprocess calls, and instruction-override attempts that hijack agent behavior.

Can I analyze a .skill file before installing it?▼

Yes. A .skill file is a zip archive that gets extracted first, then its SKILL.md, scripts, references, and assets are analyzed individually. Third-party skills from unknown sources receive heightened scrutiny during the review.

What does the security audit report include?▼

The report contains an executive summary, a findings list rated CRITICAL through LOW with evidence, positive security observations, and a 10-category checklist covering network access, PII handling, supply chain risks, and credential exposure.

What are the limitations of automated skill security review?▼

The audit is evidence-based on visible code and instructions, so heavily obfuscated payloads or runtime-only behaviors may evade detection. Skills from unknown provenance should still receive manual code review before deployment.
