Conciseness

The body is dense with domain knowledge Claude does not inherently have (risk-frequency table, clause-scope table, 30/60-day timelines) and never pads with basic explanations of what an audit or ISO standard is. It is not 5 because a few sections could be trimmed: the "Reference Documentation" section re-describes reference contents, the inline "Audit Questions by Clause" and sample JSON duplicate detail available in the references, and the closing metrics table is nice-to-have rather than essential.

Actionability

Guidance is fully concrete and executable: copy-paste bash invocations ("python scripts/audit_schedule_optimizer.py --processes processes.json --output json") that match the script's actual usage, literal interview questions ("Show me the document master list"), a fill-in finding template with a worked example (the overdue EQ-042 pH meter calibration), and a decision tree with specific timelines. This matches the anchor for copy-paste-ready commands with specific examples covering the common cases.

Workflow Clarity

Four workflows (planning, execution, nonconformity management, external audit prep) each present a clear 1-8 numbered sequence with an explicit bolded "**Validation:**" checkpoint, plus checklists (auditor independence, pre-audit readiness) and a CAPA closure loop ("Finding closed only after effective CAPA"). It falls between anchors 4 and 5: above 4's "minor validation gaps" because validations are explicit and checklists exist, but below 5 because no validation step includes an error-recovery branch (what to do when "All ISO 13485 clauses covered within cycle" fails), unlike the anchor-5 "if errors: fix and re-validate" pattern.

Progressive Disclosure

Good structure overall: a table of contents, well-signaled one-level-deep references ("See `references/iso13485-audit-guide.md` for complete question sets" plus a dedicated Reference Documentation section describing each file's contents), and detail appropriately pushed to references. It is not 5 because the bundle contains a third reference, `references/iso13485_audit_playbook.md`, that is never referenced from SKILL.md — its 7-phase workflow content is undiscoverable via the skill's navigation, and it in turn points to a nonexistent `compliance-os/scripts/audit_simulator.py`. It stays above anchor 3 because the references that are cited are clearly signaled, not buried.

Specificity

"Covers audit planning, execution, nonconformity classification, and CAPA verification" lists four concrete capabilities anchored to the "ISO 13485 internal audit expertise for medical device QMS" domain, matching the anchor for several specific actions with minor gaps. It is not 3 (more than 1-2 actions, all domain-specific rather than generic) and not 5 (the lead phrase "internal audit expertise" is a noun-phrase summary rather than a direct verb list, and external audit prep appears only in the when-clause, not the what).

Completeness

Both questions are explicitly answered: what — "Covers audit planning, execution, nonconformity classification, and CAPA verification"; when — "Use when planning internal audits, executing audits, classifying findings, preparing for external audits, or managing an audit program" with concrete trigger phrases. This mirrors the anchor-5 exemplar's what+when structure, clearly above anchor 4 where the when is only weakly specified.

Trigger Term Quality

"Use when planning internal audits, executing audits, classifying findings, preparing for external audits, or managing an audit program" supplies natural phrases users would say. Good keyword coverage but missing common variations such as "audit findings", "CAPA", "audit schedule", and "certification/regulatory audit" — matches anchor 4 rather than 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

"ISO 13485 internal audit expertise for medical device QMS" carves out a clear niche with distinct, audit-specific triggers, so conflict risk is minimal. It sits above anchor 4 (which involves minor overlap with closely related skills) because the ISO 13485/medical-device framing disambiguates from generic audit or ISO 9001/27001 audit skills; only a hypothetical sibling medical-device QMS skill would overlap.
