Design Audit — Claude Code Skill

Audit existing UIs against Universal Design System standards. Evaluates WCAG accessibility, color contrast, typography, spacing, component patterns, and industry anti-patterns. Produces a scored report with actionable CSS fixes.

How This Skill Works

Step 1: Identify the Target

Accept input as:

A URL to screenshot/analyze
A description of the current UI
A code file (HTML/CSS/JSX) to evaluate
A screenshot to visually inspect

Step 2: Detect Industry Context

Use src/scripts/core.py: DomainDetector to classify the product's sector and type, then load relevant anti-patterns from src/data/anti-patterns.csv.

Step 3: Evaluate 10 Categories

Score each category 1-10:

#	Category	Weight	What to Check
1	Color Contrast	10	WCAG AA (4.5:1 text, 3:1 UI), color independence
2	Typography	9	Hierarchy (h1>h2>h3), size scale, line height, font pairing
3	Spacing	8	Consistent scale, adequate padding, breathing room
4	Component Quality	8	States (hover/focus/disabled), accessibility labels
5	Navigation	7	Clarity, depth, mobile adaptation, breadcrumbs
6	Responsiveness	8	Mobile layout, touch targets (44px), breakpoints
7	Accessibility	10	Keyboard nav, screen reader, focus indicators, alt text
8	Visual Consistency	7	Border radius, shadow, color usage consistency
9	Performance	6	Image sizes, font loading, critical CSS
10	Anti-Pattern Check	8	Industry-specific violations from anti-patterns database

Step 4: Generate Report

# Design Audit Report

**Overall Grade: B+ (78/100)**
**Industry: [sector] | Product: [type]**

## Category Scores

| Category | Score | Issues |
|----------|-------|--------|
| Color Contrast | 8/10 | 2 minor issues |
| Typography | 6/10 | 4 issues found |
| ... | ... | ... |

## Critical Issues (Fix Immediately)
1. [Issue]: [Description]
   Fix: [CSS snippet]

## Quick Wins (< 1 hour each)
1. [Issue]: [Fix]

## Long-term Improvements
1. [Issue]: [Recommendation]

## Anti-Patterns Detected
- [CRITICAL] [anti-pattern name]: [description]
  Alternative: [from anti-patterns.csv]

Step 5: Provide CSS Fixes

All fixes use Universal Design System tokens:

/* Fix: Low contrast text */
.problematic-text {
  color: var(--color-text-primary);  /* was: #999 → now: #111118 */
}

/* Fix: Missing focus indicator */
button:focus-visible {
  outline: 2px solid var(--color-brand-primary);
  outline-offset: 2px;
}

/* Fix: Touch target too small */
.small-button {
  min-height: 44px;
  min-width: 44px;
  padding: var(--space-3) var(--space-4);
}

Grading Scale

Grade	Score	Meaning
A+	95-100	Exceptional, production-ready
A	90-94	Excellent, minor polish needed
B+	85-89	Good, some improvements needed
B	80-84	Solid, noticeable gaps
C+	70-79	Fair, significant issues
C	60-69	Below average, major rework needed
D	50-59	Poor, fundamental problems
F	<50	Failing, rebuild recommended
