This is an excellent skill that demonstrates best practices: it's concise yet complete, provides concrete executable examples, includes clear anti-patterns in the DO NOT section, and has a well-structured workflow with verification. The reference tables for validation rules and data types are particularly useful for ensuring consistent output.

Dimension	Reasoning	Score
Conciseness	The skill is lean and efficient, providing only necessary information without explaining concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context.	3 / 3
Actionability	Provides fully concrete, copy-paste ready examples including complete Mermaid syntax, exact table formats with all columns, and specific validation rule values. The example entity table is complete and executable.	3 / 3
Workflow Clarity	Clear 5-step workflow with explicit verification step at the end. Uses TodoWrite for tracking progress and includes a validation checkpoint ('Verify every entity has an attribute table').	3 / 3
Progressive Disclosure	Well-organized with clear sections: DO NOT rules upfront, document structure, example, reference tables, and workflow. Content is appropriately structured for a single-file skill under 100 lines with no need for external references.	3 / 3
	Total	12 / 12 Passed

Description

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 a well-crafted skill description that excels across all dimensions. It provides specific concrete outputs (ER diagrams, attribute tables), uses natural trigger terms that users would actually say (ERD, database schema, entity relationship diagram), includes an explicit 'Use when...' clause, and carves out a distinct niche that minimizes conflict with other skills.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'Creates entity model documents', 'Mermaid.js ER diagrams', and 'attribute tables'. These are concrete, actionable outputs rather than vague language.	3 / 3
Completeness	Clearly answers both what ('Creates entity model documents with Mermaid.js ER diagrams and attribute tables') AND when (explicit 'Use when...' clause with multiple trigger scenarios).	3 / 3
Trigger Term Quality	Excellent coverage of natural terms users would say: 'database schema', 'ERD', 'entity relationship diagram', 'model data entities', 'visualize a database design', 'data model document'. Includes both abbreviations (ERD) and full phrases.	3 / 3
Distinctiveness Conflict Risk	Clear niche focused specifically on ER diagrams and database modeling with Mermaid.js. The combination of 'entity model', 'ERD', 'database schema', and 'Mermaid.js' creates a distinct trigger profile unlikely to conflict with general diagramming or database skills.	3 / 3
	Total	12 / 12 Passed
