Conciseness

The body is directive and lean with no concept explanations, but the bare "Knowledge Reference" list of ~25 tool/standard names partially duplicates what references/sast-tools.md already covers, and the maintainer footer lines add tokens without guidance value.

Actionability

The Scan step provides five copy-paste-ready commands (semgrep, bandit, gitleaks, npm audit, trivy) and the example finding entry is a complete fill-in template. Minor gaps: the Scope step ("Map attack surface and critical paths") and Report step give no in-body specifics, deferring entirely to references.

Workflow Clarity

The five-step Core Workflow (Scope → Scan → Review → Test and classify → Report) is clearly sequenced with explicit validation checkpoints at nearly every step: "Confirm written authorization", "Verify written scope authorization before active testing", "Validate findings", "Confirm findings with stakeholder before finalizing", plus MUST DO/MUST NOT checklists.

Progressive Disclosure

The Reference Guide table maps six topics to exact file paths (all verified to exist in references/) with explicit "Load When" conditions — a clear one-level-deep overview with well-signaled navigation and no content that belongs in a separate file inlined.

Specificity

Lists multiple concrete actions with named outputs: "Identifies security vulnerabilities, generates structured audit reports with severity ratings, and provides actionable remediation guidance" plus "Produces vulnerability reports, prioritized recommendations, and compliance checklists" — comprehensive coverage of the domain.

Completeness

Clearly answers both questions: the "what" is explicit (identify vulnerabilities, generate severity-rated reports, provide remediation guidance) and the "when" is explicit via "Use when conducting security audits... Invoke for SAST scans, penetration testing..." with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural trigger terms including synonyms and abbreviations: "security audits", "SAST scans", "penetration testing", "DevSecOps practices", "cloud security reviews", "dependency audits", "secrets scanning", "compliance checks" — phrases users would naturally say when needing this skill.

Distinctiveness Conflict Risk

The security-audit niche is mostly distinct with dedicated triggers (SAST, secrets scanning, CVSS-style severity), but "reviewing code for vulnerabilities" overlaps a general code-review skill, creating minor conflict risk.
