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 clear constraints using MUST/SHOULD/NEVER language and specific values in organized tables. Its main weaknesses are the lack of executable code examples (CSS variables, Tailwind config, component snippets) and some redundant reference data that could be split into separate files. Adding implementation examples and trimming repeated information would significantly improve both actionability and conciseness.
Suggestions
Add executable code examples: a CSS custom properties block defining the semantic tokens, a Tailwind config snippet, or a sample component implementation showing the design system in action.
Remove redundant sections — the 'Border Radius Reference' repeats the Borders section scale, and 'Typography Reference' repeats font family info already in the table. Consolidate or remove duplicates.
Split detailed reference tables (full text styles list, detected layout patterns) into a separate REFERENCE.md file, keeping SKILL.md focused on the core constraints and quick-start guidance.
Add a contrast ratio validation step or tool recommendation to make the accessibility MUST constraint (4.5:1 ratio) actionable rather than just declarative.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with clear tables and MUST/SHOULD/NEVER constraints, but includes some redundant information — the 'Border Radius Reference' section repeats the scale already listed in the Borders section, the 'Typography Reference' section repeats font info, and the 'Detected Layout Patterns' section lists raw data without clear actionable guidance. The text styles table has many one-off entries that could be condensed. | 2 / 3 |
Actionability | The skill provides specific values (hex codes, pixel sizes, font weights) which are concrete, and uses clear MUST/SHOULD/NEVER directives. However, it lacks executable code examples — no CSS snippets, no Tailwind classes, no component code showing how to implement these tokens. For a UI design system skill, copy-paste ready code (e.g., CSS custom properties, Tailwind config) would significantly improve actionability. | 2 / 3 |
Workflow Clarity | The 'When to Apply' section provides clear triggers, and the content is organized by design concern (colors, typography, spacing, etc.), which creates an implicit workflow. However, there's no sequenced process for building a Cal-style interface, no validation steps (e.g., checking contrast ratios), and no guidance on how to compose these constraints together when building a complete UI. | 2 / 3 |
Progressive Disclosure | The content is well-organized with clear section headers and tables, making it scannable. However, it's a fairly long monolithic document that could benefit from splitting detailed reference tables (all text styles, layout patterns) into separate reference files, keeping SKILL.md as a concise overview with links to detailed specs. | 2 / 3 |
