How to Use This Skill

When the user invokes /refactoring-ui, you should:

1. If reviewing existing code/UI:

   • Read the relevant files
   • Identify issues based on Refactoring UI principles
   • Provide specific, actionable fixes with code examples

2. If building new UI:

   • Apply principles proactively
   • Use proper spacing scales, typography, and color systems
   • Follow hierarchy best practices

3. If asked for a general review:

   • Run through the Quick Review Checklist below
   • Prioritize high-impact improvements

Quick Review Checklist

Hierarchy

• Is there clear primary/secondary/tertiary distinction?
• Using weight and color, not just size?
• Are labels minimized where format implies meaning?

Spacing

• Using a consistent spacing scale (4, 8, 12, 16, 24, 32, 48...)?
• Related elements closer than unrelated?
• Content constrained to readable widths?

Typography

• Using a defined type scale?
• Line height proportional to font size?
• Line length under 75 characters?

Color

• Using HSL for color manipulation?
• 8-10 shades per color defined?
• Meeting accessibility contrast ratios?

Depth

• Shadows consistent (same light source)?
• Elevation levels match UI importance?
• Using overlap for visual interest?

Polish

• Form elements enhanced from defaults?
• Empty states designed, not generic?
• Using accent borders where appropriate?

Response Format

When providing feedback:

## Issue: [Brief description]

**Principle:** [Which Refactoring UI principle applies]

**Current:**
[Code or description of current state]

**Recommended:**
[Code or description of improved state]

**Why:** [Brief explanation of the improvement]

Example Interaction

User: "Review this card component"

Response:

## Issue: Flat hierarchy

**Principle:** De-emphasize to emphasize (Chapter 9)

**Current:**
```jsx
<div className="p-4">
  <span className="text-gray-700">Product Name</span>
  <span className="text-gray-700">$99.00</span>
  <span className="text-gray-700">In Stock</span>
</div>

Recommended:

<div className="p-6">
  <h3 className="text-lg font-semibold text-gray-900">Product Name</h3>
  <span className="text-2xl font-bold text-blue-600">$99.00</span>
  <span className="text-sm text-gray-500">In Stock</span>
</div>

Why: Creates clear visual hierarchy through font size, weight, and color differentiation.
