Implementation
100%This is a well-crafted skill that demonstrates excellent token efficiency while providing fully actionable CSS patterns. The mobile-first approach is consistently demonstrated across all examples, and the best practices section adds value without redundancy. The external MDN links appropriately defer comprehensive documentation.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, presenting only essential CSS patterns without explaining what responsive design is or how CSS works. Every section delivers actionable code with minimal commentary. | 3 / 3 |
Actionability | All code examples are fully executable CSS that can be copied directly into a stylesheet. Specific breakpoints, property values, and complete selectors are provided throughout. | 3 / 3 |
Workflow Clarity | For this single-purpose skill (CSS patterns), the workflow is implicit but clear: apply mobile-first base styles, then layer media queries. The best practices section provides a clear sequence ('Start with mobile styles first'). | 3 / 3 |
Progressive Disclosure | Content is well-organized into logical sections (media queries, grid, typography, images, navigation) with external MDN references for deeper learning. The skill stays focused without becoming monolithic. | 3 / 3 |

Activation
100%This is a well-crafted skill description that follows best practices. It uses third person voice, lists specific technologies and techniques, includes an explicit 'Use when...' clause with natural trigger terms, and carves out a distinct niche around responsive CSS layout systems.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Builds adaptive web interfaces using Flexbox, CSS Grid, and media queries with a mobile-first approach' - names specific technologies and approaches. | 3 / 3 |
Completeness | Clearly answers both what ('Builds adaptive web interfaces using Flexbox, CSS Grid, and media queries') AND when ('Use when creating multi-device layouts, implementing flexible UI systems, or ensuring cross-browser compatibility'). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'Flexbox', 'CSS Grid', 'media queries', 'mobile-first', 'multi-device layouts', 'flexible UI', 'cross-browser compatibility' - good coverage of terms developers naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused on responsive/adaptive CSS layout techniques with distinct triggers like 'Flexbox', 'CSS Grid', 'mobile-first', 'multi-device layouts' - unlikely to conflict with general web development or other CSS skills. | 3 / 3 |
