Conciseness

The body is two lines — a maintainer comment and "Load and follow the shared skill at ~/.agents/skills/security-audit/SKILL.md" — with zero padding and nothing explained that Claude already knows. Every token earns its place; there is nothing to trim, so it exceeds the 4 anchor's "minor instances of over-explanation".

Actionability

The pointer is concrete (an exact path and an explicit, executable instruction), but all substantive guidance for performing the audit is missing from the body — it matches "some concrete guidance but incomplete; missing key details". Not 4 because the gap is not minor (the entire methodology lives elsewhere); not 2 because the instruction is a specific direction, not a vague high-level hint.

Workflow Clarity

The body contains a single coherent handoff step but no sequenced multi-phase audit workflow and no validation checkpoints — the confidence and verification gates are only named in the description, never sequenced here. This fits "rough sequence present but many gaps; validation absent"; not 1 because the one step present is unambiguous rather than incoherent, and not 3 because no actual audit steps are listed at all.

Progressive Disclosure

The single reference is clearly signaled and one level deep ("Load and follow the shared skill at ..."), but the body provides no overview or orientation of its own, and the referenced path lies outside the bundle (no references/, scripts/, or assets/ exist; the shared path is not part of this skill bundle). This fits "some structure but could be better organized"; not 4 because a contentless stub whose only reference is external goes beyond "minor organization gaps", and not 2 because the reference is not buried and nothing is inlined.

Specificity

Lists multiple specific concrete areas — "secrets archaeology, dependency supply chain, CI/CD pipeline, LLM/AI attack surface, agent skill supply chain, OWASP Top 10, STRIDE threat model, and data classification" — plus two concrete control mechanisms ("a confidence gate and a pre-emit verification gate that suppress speculative findings"). Coverage is comprehensive rather than having the minor gaps of the 4 anchor.

Completeness

Explicitly answers both what (the enumerated audit scope and gates) and when ("Use when asked for..." with concrete trigger phrases), and adds a negative boundary ("Not for reviewing a single diff"). This clearly matches the 5 anchor; the 4 anchor's weaker "when" does not apply since triggers are explicit and concrete.

Trigger Term Quality

"Use when asked for a security audit, threat model, pentest-style review, OWASP pass, or a pre-release security check" gives good, natural keyword coverage a user would actually say. Not 5 because common variations like "security review", "penetration test", or "vulnerability scan" are missing; not 3 because the present terms are natural and varied rather than generic.

Distinctiveness Conflict Risk

Clear niche (infrastructure-first repository security audit) with distinct triggers, and it explicitly disambiguates the nearest competing skill: "Not for reviewing a single diff - use requesting-code-review for that." Minimal conflict risk; even the 4 anchor's "minor overlap risk" is addressed by this exclusion clause.
