50%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill provides a solid conceptual framework and useful checklist for macOS-native UI design, with good progressive disclosure structure pointing to reference files. Its main weaknesses are the lack of executable code examples (no React/HTML template to start from) and missing validation/verification steps. The content is reasonably concise but could trim some philosophical framing and opinion statements.
Suggestions
Add a concrete, copy-paste-ready code example — e.g., a minimal React component showing a macOS window with title bar, traffic lights, sidebar, and proper font stack
Add a validation/verification step to the workflow — e.g., a visual checklist to verify native feel (does dark mode work? are traffic lights positioned correctly? do keyboard shortcuts have visual feedback?)
Trim philosophical framing in 'Core Philosophy' to a single sentence and remove opinion padding like 'This is non-negotiable for native feel'
Ensure the referenced bundle files (references/layout-and-composition.md, etc.) actually exist, or inline the most critical content if they don't
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient but includes some philosophical framing ('A native app is not a destination...') and explanatory text that doesn't add actionable value. The checklist items are reasonably tight but some could be tightened (e.g., 'This is non-negotiable for native feel' is opinion padding). | 2 / 3 |
Actionability | The checklist provides concrete guidance and the implementation notes give specific CSS values (border-radius, font stacks, blur filters), which is good. However, there's no executable code example — no React component, no HTML snippet, no copy-paste-ready template. The guidance is specific but not fully executable. | 2 / 3 |
Workflow Clarity | The 'Before You Code' section establishes a read-first sequence, and the checklist provides a clear pre-flight order. However, there's no validation or verification step — no way to check if the result actually feels native, no feedback loop for testing light/dark mode, no checkpoint after implementing the window chrome. | 2 / 3 |
Progressive Disclosure | The skill references three separate files (layout-and-composition.md, interaction-patterns.md, visual-design.md) with clear signaling about when to read each. However, no bundle files were provided, so these references point to non-existent files. The main content itself is well-structured but the implementation notes section could arguably be split out for different target platforms. | 2 / 3 |
