Discovery

77%

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 solid description that clearly articulates specific capabilities and includes explicit 'Use for' guidance. The main weaknesses are limited trigger term coverage (missing common synonyms and file types users might mention) and moderate overlap risk with general UI/frontend skills. The persona mention ('Senior UI Designer') doesn't add selection value.

Suggestions

Add more natural trigger terms users would say, such as 'style guide', 'UI kit', 'spacing scale', 'color palette', 'typography system', or tool-specific terms like 'Figma handoff'

Strengthen distinctiveness by specifying file formats or outputs (e.g., 'generates CSS variables, JSON tokens') to differentiate from general UI design skills

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'design token generation, component documentation, responsive design calculations, and developer handoff tools' - these are clear, actionable capabilities.

3 / 3

Completeness

Clearly answers both what (design token generation, component documentation, responsive calculations, handoff tools) AND when ('Use for creating design systems, maintaining visual consistency, and facilitating design-dev collaboration').

3 / 3

Trigger Term Quality

Includes some relevant terms like 'design system', 'design tokens', 'component documentation', but missing common variations users might say like 'style guide', 'UI kit', 'spacing', 'colors', 'typography tokens', or 'Figma handoff'.

2 / 3

Distinctiveness Conflict Risk

While 'design system' and 'design tokens' are fairly specific, terms like 'UI design' and 'visual consistency' could overlap with general UI/UX skills or frontend development skills. The 'Senior UI Designer' persona adds some distinction but isn't a trigger term.

Implementation

52%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The skill is concise and well-structured at a high level, but lacks the actionable depth needed for effective use. It describes capabilities without demonstrating them through examples or providing clear workflows for common design system tasks. The single script reference needs concrete input/output examples to be truly useful.

Suggestions

Add a concrete example showing the script invocation with sample brand color and the resulting token output (e.g., JSON snippet)

Include a workflow section explaining the typical design system creation process: 1) Generate tokens → 2) Validate output → 3) Export to target format

Add links to detailed documentation files for component architecture, accessibility guidelines, and developer handoff templates

Provide at least one complete input/output example demonstrating the token generator with expected results

DimensionReasoningScore

Conciseness

Content is lean and efficient, listing capabilities and script usage without unnecessary explanation. No padding or concepts Claude already knows.

3 / 3

Actionability

Provides CLI usage pattern and parameter options, but lacks executable code examples, sample outputs, or concrete input/output demonstrations. The script reference is helpful but incomplete without showing actual usage results.

2 / 3

Workflow Clarity

No workflow sequence provided for design system creation. Lists capabilities and a single script but doesn't explain how to use them together, when to use each feature, or any validation steps for the generated tokens.

1 / 3

Progressive Disclosure

Content is brief and organized with clear sections, but references a script without linking to documentation or examples. No indication of where to find detailed API reference, examples, or advanced usage patterns.
