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.

DimensionReasoningScore

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.

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.

DimensionReasoningScore

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.
