Content
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, concrete values (colors, sizes, spacing) organized into clear sections with tables. However, it lacks executable code examples showing implementation, reads more like a raw design audit export than an actionable skill, and some token values seem inconsistent or suspicious (e.g., 'warning' being white, 'destructive' matching 'text-primary'). The skill would benefit significantly from implementation examples and a clearer workflow for applying these constraints.
Suggestions
Add executable code examples showing implementation - e.g., a CSS custom properties block defining the design tokens, a Tailwind config snippet, or a React component example using the design system.
Add a brief workflow section explaining the order of operations when building a Brex-style UI (e.g., set up tokens first, then layout grid, then typography, then components).
Review semantic token assignments for correctness - 'warning' mapped to #FEFEFD (white) and 'destructive' matching 'text-primary' (#D98C71) seem like errors that could mislead implementation.
Split detailed reference tables (full text styles, layout patterns) into a separate REFERENCE.md file and keep SKILL.md as a concise overview with the most essential tokens and rules.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with well-structured tables and clear MUST/SHOULD/NEVER constraints, but includes some redundancy (e.g., 'Typography Reference' section repeats info already in the Text Styles table, detected layout patterns feel like raw data dumps rather than actionable guidance). Some sections like the color table have questionable semantic naming (e.g., 'warning' mapped to white, 'destructive' same as 'text-primary'). | 2 / 3 |
Actionability | Provides specific values (hex codes, pixel sizes, font weights) which are concrete, but lacks executable code examples showing how to implement these in actual CSS/Tailwind/React. The skill describes design tokens and constraints but doesn't show copy-paste ready implementation patterns like CSS custom properties definitions or Tailwind config snippets. | 2 / 3 |
Workflow Clarity | For a design system reference skill, there's no clear workflow for how to apply these guidelines when building a UI. The 'When to Apply' section is minimal. There's no sequencing guidance (e.g., start with layout, then typography, then colors) and no validation steps to verify the implementation matches the design system. | 2 / 3 |
Progressive Disclosure | The content is well-organized with clear section headers and tables, but it's a fairly long monolithic document. Some sections like the detailed text styles table and layout patterns could be split into reference files, with the main SKILL.md providing a concise overview and linking to detailed specs. | 2 / 3 |
