Content
35%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is comprehensive in scope but suffers significantly from verbosity — it inlines large amounts of content (design tokens, aesthetic anchor descriptions, Nielsen heuristics) that Claude already knows or that should be in referenced files. The actionability is moderate: it provides good templates and token structures but lacks concrete guidance on how Claude should actually produce wireframes/prototypes in a text-based medium. The workflow is present but missing explicit validation gates.
Suggestions
Move the full design tokens TypeScript file, aesthetic anchor descriptions, and Nielsen heuristics checklist to separate referenced files (e.g., `docs/design-tokens-template.ts`, `docs/aesthetic-anchors.md`) and keep only a brief summary with links in the main SKILL.md.
Add a concrete workflow with validation checkpoints: e.g., '1. Choose aesthetic anchor → 2. Define tokens → 3. Validate tokens against anchor (no anti-patterns) → 4. Create wireframe → 5. Run Nielsen checklist → 6. Only proceed to handoff when all 10 heuristics pass.'
Clarify how Claude should actually produce wireframes in a text environment — provide a concrete example of an ASCII wireframe, markdown mockup, or structured output format that constitutes a 'wireframe' deliverable.
Remove or drastically shorten content Claude already knows (Nielsen heuristics definitions, basic responsive design rules like 'hamburger in mobile') and replace with project-specific constraints or non-obvious guidance only.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely verbose at ~300+ lines. It includes a full design token file with hardcoded color values (which are explicitly called out as anti-patterns in the aesthetic anchors section itself — blue/indigo defaults), extensive lists of aesthetic anchors with descriptions Claude could infer, Nielsen heuristics that Claude already knows, and skeleton loading patterns that are basic UI knowledge. The token file alone is ~60 lines of static values that could be a referenced file. | 1 / 3 |
Actionability | The skill provides a concrete TypeScript token file and structured component specification templates, which are actionable. However, much of the content is descriptive checklists and guidelines rather than executable steps. The wireframe/prototyping process itself lacks concrete tooling commands or output format examples — it says 'create wireframes' but doesn't show how Claude should actually produce them in a text-based environment. | 2 / 3 |
Workflow Clarity | The skill lists responsibilities, inputs, outputs, and handoff checklists, providing a reasonable sequence. However, there are no explicit validation checkpoints or feedback loops in the design process itself — no step like 'validate accessibility before handoff' or 'review against heuristics checklist before proceeding.' The 'Evidencia de Conclusao' section is minimal and lacks verification steps for the destructive/irreversible nature of design decisions propagating downstream. | 2 / 3 |
Progressive Disclosure | The skill references external files like `docs/skill-guides/ui-ux-design.md` and `docs/skill-guides/ui-component-mcps.md` for detailed content, which is good. However, the main file itself is monolithic — the full design tokens, all 11 aesthetic anchors with descriptions, the complete Nielsen checklist, and skeleton patterns are all inline when they could be in referenced files. The token file especially should be a separate reference. | 2 / 3 |
