The body is padded with generic filler Claude already knows — "This skill seamlessly integrates with all other components", "Required dependencies installed", "The skill produces structured output relevant to the task" — matching the verbose/explains-known-concepts anchor rather than the lean one.

There is no executable code, command, or file path; guidance is abstract ("Invoke the Security Auditor Expert agent", "Execute the selected tool") and the real bundled security_scan.py is never referenced, matching the 'describes rather than instructs' anchor.

Steps are sequenced (Analysis Selection → Execution → Reporting) but lack validation checkpoints for an audit that surfaces findings and remediation, and the Instructions section is generic boilerplate — above the missing-sequence anchor but below the explicit-validation one.

Real bundle files exist (scripts/security_scan.py and three asset templates) but are not linked from the body, while the body instead references nonexistent 'agents'; structure is present but navigation is mis-signaled and content that should be split stays inline.

The description names concrete actions across a defined domain — "vulnerability scanning, compliance checking, and cryptography review" on "code, infrastructure, and configurations" — matching the 'lists multiple specific concrete actions' anchor.

It explicitly answers both what it does ("conducting comprehensive security audits" with named sub-tasks) and when to use it ("Use when assessing security or running audits. Trigger with phrases like..."), the top anchor.

It lists natural phrases a user would actually say — "'security scan', 'audit', or 'vulnerability'" — giving good coverage of common utterances rather than technical jargon.

The security-audit niche with plugin-specific tool framing and distinct trigger phrases is unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
