The body is ~670 lines and inlines large blocks a competent model does not need (a 33-item procedure list, regional regulatory summary, retention periods, generic best-practices/common-mistakes) that the skill itself says belong in reference files, plus an unrelated promotional 'K-Dense Web' section.

Concrete steps, clause numbers, and checklists are present, but the headline executable tool (`python scripts/gap_analyzer.py ...`) and the templates it directs the user to are referenced yet not actually provided, so the most concrete actions cannot be executed.

Multi-step processes are clearly sequenced (Core Workflow sections 1-5, phased priority order) with explicit validation checklists (quality-manual validation checklist, pre-audit checklist, 'Validate completeness' step).

References are clearly signaled and one level deep (a 'Resources' section lists them), but none of the referenced bundle files (references/*.md, scripts/gap_analyzer.py, assets/templates/*) exist, and content that should live in those files is inlined in SKILL.md instead.

Lists multiple concrete actions — 'conducting gap analysis', 'creating Quality Manuals', 'developing required procedures and work instructions', 'preparing Medical Device Files', 'identifying missing documentation' — rather than vague language.

Explicitly answers both what (preparing ISO 13485 certification documentation, six numbered actions) and when ('Use when users need help with ISO 13485 QMS documentation... Also use when users mention medical device regulations, QMS certification, FDA QMSR, EU MDR...').

Covers natural terms a user would say — 'ISO 13485', 'QMS certification', 'Medical Device Files', 'FDA QMSR', 'EU MDR', 'medical device regulations', 'quality system documentation'.

Occupies a clear, narrow niche (ISO 13485 medical-device QMS documentation) with highly domain-specific triggers unlikely to fire for unrelated skills.
