Names the domain (frontend code security audit) and mentions specific vulnerability types (XSS, CSRF), but uses '等' (etc.) which is vague. Does not list comprehensive concrete actions beyond 'audit' and 'detect'.

Clearly answers both what (performs security audits on frontend code, detects XSS/CSRF vulnerabilities) and when (when user requests code review or asks about code security) with explicit trigger guidance.

Includes some relevant terms like '代码审查' (code review), '代码安全性' (code security), 'XSS', 'CSRF', but missing common variations like 'vulnerability scan', 'security check', 'penetration test', or file extensions like '.js', '.html'.

Focuses on frontend security which is somewhat specific, but '代码审查' (code review) is generic and could overlap with general code review skills. The security focus helps but 'frontend' scope could still conflict with general security audit skills.

The skill is lean and efficient, providing only essential information without explaining concepts Claude already knows (like what XSS or CSRF are). Every section serves a clear purpose.

The skill provides a checklist and workflow but lacks concrete code examples or specific commands. It references external files for detailed rules but doesn't include executable guidance in the main skill.

The 3-step workflow is present but lacks validation checkpoints. For security auditing (a potentially high-stakes operation), there's no explicit verification step or feedback loop for handling discovered vulnerabilities.

Clear structure with well-signaled one-level-deep references to audit-rules.md, report-template.md, and security-checklist.md. The main skill serves as a concise overview pointing to detailed materials.
