Conciseness

The body is dense and imperative throughout — table-driven phases, exact formats, no explanation of concepts Claude already knows. However, the trailing '## Keywords' section ('Security Audit, Security Review, OWASP, SAST, SCA, Vulnerability, CVE, Threat Model...') duplicates the description's triggers and conflicts with them (the description excludes generic 'security review' and threat-modeling; the keyword list includes both). This trimmable redundancy keeps it at anchor 4 rather than 5, but it is far from the padded over-explanation of anchor 3.

Actionability

Fully executable guidance: exact commands ('npm audit --json', 'pip-audit --format json', 'python3 tools/github-integration/flow.py tag-phase --item <ID> --phase sec'), exact output paths, a binding five-field finding format, a canonical audit summary block, and a canonical commit message. The only placeholders ({PROJECT}, {ID}) are inherent template variables, so this matches anchor 5's copy-paste readiness.

Workflow Clarity

Clear sequence (six-phase audit table) with explicit validation and feedback loops: the Fix-Loop has a user decision point, 'run affected tests (no regressions)', an automatic re-audit reporting deltas only ('Loop until all in-scope findings resolve or the user aborts'), and '/consistency-check mode A' as an error-recovery net for missed backlog rows and dead links. This matches anchor 5's explicit checkpoints and error-recovery loops.

Progressive Disclosure

The body is a clear overview with a phases table pointing one level deep to bundled, verified files (references/cwe-patterns.md, references/owasp-checklist.md, references/owasp-llm-checklist.md). But several referenced paths are absent from the bundle — templates/AUDIT-TEMPLATE.md, skills/project-conventions/SKILL.md and its references/team-workflow.md, and skills/requirements-engineering/templates/BACKLOG-TEMPLATE.md — so navigation breaks outside the shipped references. Good structure with minor organization gaps fits anchor 4; the clearly signaled, one-level-deep bundled references keep it above anchor 3.

Specificity

Lists multiple concrete actions with comprehensive coverage: 'Performs a... formal security audit', 'produces a written audit report (AUDIT-{PROJECT}-{DATE}.md) with prioritized findings (H/M/L) and a remediation plan', and enumerates the full scope (SAST, OWASP Top 10, OWASP LLM Top 10, SCA, Zero Trust validation, code quality). Fits the anchor-5 example's comprehensiveness; no minor coverage gaps that would justify a 4.

Completeness

Explicitly answers both questions: what ('formal security audit of an entire codebase... produces a written audit report... with prioritized findings and a remediation plan') and when ('TRIGGER ONLY when the user explicitly requests a formal full-codebase audit producing a report'). The when-clause includes concrete trigger phrases, matching anchor 5 exactly; a 4 would require the when to be less explicit.

Trigger Term Quality

Natural trigger phrases span synonyms and two languages: "security audit", "OWASP audit", "full security review", "SCA audit", "dependency audit", "CVE audit", "Sicherheitsaudit", "Codebase auditieren", "AUDIT-Report erstellen". These are phrases a user would actually say; coverage is comprehensive rather than the 'a few natural terms missing' of anchor 4.

Distinctiveness Conflict Risk

The negative triggers actively disambiguate against the nearest competing skill: 'DO NOT trigger for: PR-level security checks (use the built-in security-review skill), one-off security questions, threat-modeling discussions without an audit report'. Clear niche (formal full-codebase audit with report) with conflict risk actively managed, which exceeds anchor 4's 'minor overlap risk'.
