Conciseness

The bulk is high-value, domain-specific content (clause tables with common gaps, Annex A category summary, mature-program audit cadence defaults) rather than concepts Claude already knows — but there is more than minor waste: a ~40-item Keywords section with no runtime role in the body, three multi-sentence 'This skill is NOT...' paragraphs that restate the frontmatter description, and a re-listing of the three-decision framing already given in the description. That lands at 'mostly efficient but could be tightened' rather than the 'minor instances' of anchor 4, and well above the padded verbosity of anchor 2.

Actionability

Quick Start commands are copy-paste ready and run with embedded samples when no path is given (verified in the scripts), each with an argument-taking variant; the four workflows reference real scripts and input files that exist in the bundle, and the scripts document their JSON input schemas in their docstrings. Common cases execute out of the box with no gaps, matching the fully-executable anchor 5.

Workflow Clarity

Four workflows are clearly sequenced with concrete steps and real validation checkpoints ('Confirm auditor independence per assignment', 'confirm ≥ 1 Annex A control is selected as treatment', 'Confirm coverage hits every clause and every applicable Annex A control over rolling 3 years'). It is not 5 because explicit error-recovery feedback loops (fail → fix → re-run) are absent; it is not 3 because checkpoints are genuinely present and the operations are analytical rather than destructive, so the destructive-operation cap does not apply.

Progressive Disclosure

The body is an overview that defers detail to four well-signaled, one-level-deep reference files (verified: all referenced paths in references/ and scripts/ exist, and the reference files do not cross-reference each other), with summary tables inline and full catalogues deferred. Easy navigation, content appropriately split — matches anchor 5.

Specificity

Enumerates three concrete actions — 'Where are the gaps against Clauses 4-10 and what do we close first', 'What goes in the AI risk register and which Annex A controls treat each risk', and the '12-month internal audit plan that satisfies Clause 9.2' — which is comprehensive coverage of the skill's niche, matching the anchor-5 example pattern. It is not 4 because there are no coverage gaps; each decision is a specific, named deliverable.

Completeness

Explicitly answers both questions: the 'what' via the three enumerated decisions, and the 'when' via 'Use when preparing for certification, scoping internal audit cycles, or onboarding AI systems into an existing ISMS (27001) / QMS (13485) program'. This mirrors the anchor-5 example structure; score 4 would require the 'when' to be less explicit or specific, which it is not.

Trigger Term Quality

Strong natural terms users would actually say: 'ISO/IEC 42001:2023', 'AI Management System (AIMS)', 'internal audits', 'AI risk register', 'certification', 'ISMS (27001) / QMS (13485)'. A few natural entry phrases a compliance user might say — 'AI governance', 'AI compliance' — are absent from the description (they appear only in the body's Keywords section), so it falls just short of the comprehensive-synonym coverage of anchor 5.

Distinctiveness Conflict Risk

Names the exact standard (ISO/IEC 42001:2023) and actively disambiguates against the two nearest competing skills — 'NOT an executive AI strategy skill (see chief-ai-officer-advisor). NOT EU AI Act compliance (see compliance-team-eu-ai-act)' — giving it a clear niche with minimal conflict risk. Not 4: the overlap risk with adjacent compliance skills is explicitly resolved rather than merely minor.
