Review Workflow
1. Receive Screenshot
E2E_SCREENSHOT_TAKEN event:
{
"screenshot_path": "screenshots/dashboard.png",
"page": "dashboard",
"timestamp": "2024-01-15T10:30:00Z"
}
2. Analyze with Vision
Use Claude Vision to analyze the screenshot:
Analyze this UI screenshot for UX issues:
1. Visual design quality
2. Layout consistency
3. Accessibility concerns
4. Usability problems
5. Suggested improvements
Be specific about element locations and issues.
3. Generate Report

medium | Noticeable issue | Should fix |
low | Minor polish | Nice to have |
Common Issues & Fixes
Layout Issues
Issue: Elements not aligned
Fix: Use CSS Grid or Flexbox with consistent gaps
Code:
.container {
display: grid;
grid-template-columns: repeat(3, 1fr);
gap: 1rem;
}
Color Contrast
Issue: Low contrast text
Fix: Ensure 4.5:1 ratio for normal text, 3:1 for large
Tool: Use contrast checker (WebAIM)
Code:
.text { color: #333; } /* Dark on light */
.text-light { color: #fff; } /* Light on dark */
Form UX
Issue: Placeholder-only labels
Fix: Add visible labels above inputs
Code:
<label htmlFor="email">Email Address</label>
<input id="email" type="email" />
Button States
Issue: No hover/focus states
Fix: Add interactive states
Code:
.button:hover { opacity: 0.9; }
.button:focus { outline: 2px solid blue; }
.button:disabled { opacity: 0.5; cursor: not-allowed; }

Design System Compliance
Check generated UI against design tokens:
Color Compliance
| Element | Expected | Red Flags |
|---|
| App background | bg-slate-50 (#f8fafc) | Hard-coded colors, harsh backgrounds |
| Card background | bg-white | Gray or colored cards |
| Primary text | text-slate-900 | Pure black (#000) |
| Secondary text | text-slate-600 | Too light or hard to read |
| Primary actions | bg-blue-500 | Random accent colors |
| Borders | border-slate-200 | Heavy or dark borders |
Style Compliance
| Element | Expected | Red Flags |
|---|
| Card radius | rounded-xl (12px) | Sharp corners or inconsistent radius |
| Button radius | rounded-lg (8px) | Pill buttons or sharp corners |
| Card shadow | shadow-sm | Heavy shadows or no elevation |
| Modal shadow | shadow-lg | Too subtle or harsh |
| Spacing | Consistent p-4, p-6 | Random padding values |
Interaction Compliance
| Element | Expected | Red Flags |
|---|
| Button hover | Color shift (600 shade) | No hover state |
| Focus ring | ring-2 ring-blue-500 | No focus indicator |
| Transitions | transition-colors (150ms) | Instant or slow changes |
| Disabled state | Reduced opacity | No visual difference |
Red Flags to Report
- Hard-coded hex colors instead of Tailwind classes
- Inconsistent border-radius between similar elements
- Missing hover states on interactive elements
- No focus indicators for accessibility
- Missing transition animations
- Inconsistent spacing patterns
- Overly saturated or harsh colors
- Heavy shadows on small elements
Best Practices
- Be Specific - "Button on line 45 of Header.tsx" not "A button"
- Provide Context - Explain why it's a problem
- Suggest Fixes - Include code when possible
- Prioritize - Critical > High > Medium > Low
- Track Progress - Compare before/after screenshots
- Test Responsively - Check mobile and desktop
- Consider Context - Error states, loading states, empty states
- Check Design System - Verify colors, radius, shadows match tokens
