Conciseness

The body is dense domain data with no over-explanation of known concepts, but pathway selection is presented twice (the 'Regulatory Pathway Selection Matrix' table plus the ASCII 'Pathway Selection and Classification Reference' trees), and reference-grade tables (FDA submission timeline, deficiency prevention, market priority matrices) are inlined rather than kept in the reference files.

Actionability

Highly concrete guidance — fill-in templates, submission checklists, a worked Substantial Equivalence comparison table, specific standards (ISO 10993-1, IEC 62304, MDCG 2019-16), and the command 'python regulatory_tracker.py --report status' — but that script does not exist in the bundle, so the flagship command is not actually executable.

Workflow Clarity

All five workflows are clearly numbered, each ends with an explicit bolded **Validation:** checkpoint, submission package checklists are provided, and agency-response feedback loops ('Monitor MDUFA clock and respond to AI/RTA requests within deadlines', 'Address FDA questions and deficiencies') are explicit, matching the top anchor.

Progressive Disclosure

The structure is well organized (TOC, sectioned workflows, clearly signaled one-level 'See: references/...' links), but none of the four referenced files (fda-submission-guide.md, eu-mdr-submission-guide.md, global-regulatory-pathways.md, iso-regulatory-requirements.md) nor scripts/regulatory_tracker.py exist in the bundle — every reference is dangling — and substantial content that should live in those files is inlined in SKILL.md.

Specificity

The description lists multiple specific concrete actions — 'Prepares FDA 510(k), De Novo, and PMA submission packages', 'drafts responses to FDA deficiency letters and Notified Body queries', 'develops CE marking technical documentation under EU MDR 2017/745', 'coordinates multi-market approval strategies' — with comprehensive coverage of the domain, in third-person voice.

Completeness

It explicitly answers both what (the enumerated action list) and when ('Use when users need to plan or execute FDA submissions, navigate 510(k) or PMA approval processes, achieve CE marking, prepare pre-submission meeting materials, write regulatory strategy documents, respond to agency queries, or manage compliance documentation for medical device market access') with concrete trigger phrases.

Trigger Term Quality

Natural trigger phrases users would actually say are well covered: 'FDA submissions', '510(k)', 'PMA approval', 'CE marking', 'pre-submission meeting materials', 'regulatory strategy documents', 'agency queries', 'compliance documentation', 'medical device market access', including synonyms.

Distinctiveness Conflict Risk

The medical-device regulatory affairs niche is clear and distinct from generic skills, but the description's broad FDA and EU MDR scope overlaps with the closely related specialist skills it links (fda-consultant-specialist, mdr-745-specialist), creating minor conflict risk.
