Comprehensive toolkit for preparing ISO 13485 certification documentation for medical device Quality Management Systems. Use when users need help with ISO 13485 QMS documentation, including (1) conducting gap analysis of existing documentation, (2) creating Quality Manuals, (3) developing required procedures and work instructions, (4) preparing Medical Device Files, (5) understanding ISO 13485 requirements, or (6) identifying missing documentation for medical device certification. Also use when users mention medical device regulations, QMS certification, FDA QMSR, EU MDR, or need help with quality system documentation.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that clearly defines its scope, lists specific concrete actions, and provides comprehensive trigger guidance. It uses proper third-person voice, includes both a primary 'Use when' clause with enumerated scenarios and a secondary 'Also use when' clause for related terms. The description occupies a clear, distinctive niche in medical device quality management documentation.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: conducting gap analysis, creating Quality Manuals, developing procedures and work instructions, preparing Medical Device Files, understanding requirements, and identifying missing documentation. | 3 / 3 |
Completeness | Clearly answers both 'what' (comprehensive toolkit for preparing ISO 13485 certification documentation with six enumerated capabilities) and 'when' (explicit 'Use when' clause with detailed trigger scenarios, plus an 'Also use when' clause covering related regulatory terms). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'ISO 13485', 'QMS documentation', 'gap analysis', 'Quality Manuals', 'Medical Device Files', 'medical device regulations', 'QMS certification', 'FDA QMSR', 'EU MDR', 'quality system documentation'. These are terms practitioners would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche targeting ISO 13485 medical device QMS documentation specifically. The combination of medical device regulations, specific standards (ISO 13485, FDA QMSR, EU MDR), and QMS documentation makes it very unlikely to conflict with other skills. | 3 / 3 |

Implementation
35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is comprehensive in coverage but severely over-verbose, explaining many concepts Claude already understands and repeating workflow steps across multiple sections (core workflow, common scenarios, getting started). The actionability is moderate — it references concrete tools and templates but rarely shows actual output examples or executable content beyond one bash command. The content would benefit enormously from aggressive condensation and moving reference material to linked files.
Suggestions
Reduce content by at least 50% — remove the Common Scenarios section (which largely restates the Core Workflow), trim Best Practices to only non-obvious guidance, and eliminate explanations of basic concepts like what an MDF is or general writing advice.
Move the Quick Reference section (31 procedures list, regulatory requirements, document retention) to a separate reference file and link to it, keeping SKILL.md as a concise overview.
Add concrete output examples — show a snippet of what a completed gap analysis report looks like, or a filled-in section of the Quality Manual template, rather than just describing the process abstractly.
Add explicit validation gates with feedback loops, e.g., after running gap_analyzer.py show how to interpret errors, and after document creation show a concrete validation command or checklist verification step before proceeding.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose at ~500+ lines. Extensively explains concepts Claude already knows (what an MDF is, what a Quality Manual is, general document writing best practices like 'clear, simple language' and 'avoid jargon'). The common scenarios section largely repeats the core workflow steps. Much content could be condensed by 60-70%. | 1 / 3 |
Actionability | Provides some concrete guidance like the gap_analyzer.py command and references to specific template files, but most content is procedural description rather than executable steps. The bulk of the skill describes processes at a high level ('gather organization information', 'customize template') without showing concrete examples of actual output or filled-in content. | 2 / 3 |
Workflow Clarity | Multi-step processes are listed with numbered steps and the document creation priority order is well-sequenced. However, validation checkpoints are mostly checklists of items to verify rather than explicit validation commands or feedback loops. The gap analysis workflow mentions running a script but lacks error handling or what to do if the script fails. The Quality Manual section has a validation checklist which is good but uses unchecked boxes rather than explicit verify-then-proceed gates. | 2 / 3 |
Progressive Disclosure | References to external files (references/, templates/, scripts/) are well-signaled and one level deep, which is good. However, the SKILL.md itself is monolithic with enormous amounts of inline content that should be in separate reference files — the common scenarios, best practices, quick reference of 31 procedures, regulatory requirements, and document retention sections all bloat the main file when they could be linked out. | 2 / 3 |
