50%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a reasonably well-structured design system reference with specific, opinionated constraints using clear MUST/SHOULD/NEVER language. Its main weaknesses are the lack of executable code examples (CSS custom properties, Tailwind config, or component snippets), some redundancy in the typography section, and questionable values (0px input height, surface-raised being white #FEFEFE in a dark theme). The content would benefit from concrete implementation examples and better progressive disclosure.
Suggestions
Add executable code examples: a CSS custom properties block defining the semantic tokens, a Tailwind config snippet, or a sample component implementation to make the design system immediately actionable.
Review and fix suspicious values: 0px input height and #FEFEFE (near-white) for 'surface-raised' in a dark theme seem incorrect and could lead to broken implementations.
Split detailed reference tables (typography styles, full color tokens) into a separate REFERENCE.md file, keeping SKILL.md as a lean overview with the most critical constraints and links to details.
Add a validation/verification section: e.g., how to check contrast ratios meet 4.5:1, how to verify 4px grid alignment, or a checklist for reviewing implementations against these constraints.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with clear MUST/SHOULD/NEVER constraints, but includes some redundancy (e.g., 'Border Radius Reference' section repeating '10px' already stated above, duplicate 'text-19px' entries, and the typography reference section largely restating what's in the table). The detailed tables are useful but some could be trimmed. | 2 / 3 |
Actionability | The skill provides specific values (hex codes, pixel sizes, font weights) which are concrete and actionable for design implementation. However, it lacks any executable code examples - no CSS snippets, no Tailwind config, no component code. For a UI design system skill, at least one concrete implementation example (e.g., a styled component or CSS custom properties block) would significantly improve actionability. | 2 / 3 |
Workflow Clarity | The skill is organized as a reference document rather than a workflow, which is appropriate for a design system. However, there's no guidance on the order of applying these constraints, no validation steps (e.g., how to check contrast ratios), and the 'When to Apply' section is vague. For a design system that includes destructive constraints (MUST/NEVER), some verification guidance would be valuable. | 2 / 3 |
Progressive Disclosure | The content is well-structured with clear sections and tables, but it's a monolithic file with no references to external files for detailed content. The typography section alone is quite long with multiple tables. Splitting detailed token references, component specs, and animation rules into separate files with links from a leaner overview would improve navigation. | 2 / 3 |
