Conciseness

Information-dense throughout — tables, checklists, numbered workflows, a decision tree, and code fences — with no padding or explanations of concepts Claude already knows; every line earns its place.

Actionability

Provides executable bash commands, sample JSON input, a finding-documentation template, and per-clause audit questions, but the script's own interface beyond the CLI flags is not shown inline, leaving a minor gap.

Workflow Clarity

Four multi-step workflows each end in an explicit "Validation:" checkpoint (e.g. "All ISO 13485 clauses covered within cycle"), with checklists and a classification decision tree providing clear feedback loops for these batch/program operations.

Progressive Disclosure

Body acts as an overview with bulk detail pushed to one-level-deep references (iso13485-audit-guide.md, nonconformity-classification.md) and a script, all clearly signaled and present on disk; minor gap is the orphaned references/iso13485_audit_playbook.md that is never linked from the body.

Specificity

Names the domain plus multiple concrete actions — "audit planning, execution, nonconformity classification, and CAPA verification" — giving comprehensive coverage of the skill's capabilities.

Completeness

Explicitly answers both "what" (ISO 13485 internal audit expertise covering the listed activities) and "when" ("Use when planning internal audits, executing audits, classifying findings, preparing for external audits, or managing an audit program") with concrete trigger phrases.

Trigger Term Quality

Strong natural-phrase coverage in the "Use when" clause ("planning internal audits, executing audits, classifying findings, preparing for external audits"), but a few natural synonyms (e.g. regulatory audit, MDSAP) are missing, so it sits just below comprehensive.

Distinctiveness Conflict Risk

Clear narrow niche (ISO 13485 medical-device QMS internal audit) with domain-specific triggers, minimal overlap risk with other skills.
