Testing Workflow
1. Standard Breakpoint Test
# Mobile (iPhone SE - 375×667)
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-resize.js --mobile
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-screenshot.js --output=/tmp/mobile.png
# Tablet (iPad - 768×1024)
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-resize.js --tablet
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-screenshot.js --output=/tmp/tablet.png
# Desktop (1920×1080)
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-resize.js --desktop
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-screenshot.js --output=/tmp/desktop.png
2. Additional Device Tests
# iPhone 14 Pro (393×852)
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-resize.js --iphone-pro
# Android (Pixel 7 - 412×915)
node ~/.claude/plugins/*/skills/website-debug/scripts/browser-resize.js --android
# iPad Pro (1024×1366)

3. Analysis Checklist
For each viewport, check:
Layout
- Content fits without horizontal scroll
- Columns stack appropriately
- Spacing adjusts proportionally
- No overlapping elements
Navigation
- Menu accessible (hamburger on mobile)
- All links/buttons reachable
- Touch targets ≥44px on mobile
Typography
- Text readable without zooming
- Line length appropriate (45-75 chars ideal)
- Headings scale properly
Images
- Images scale without distortion
- No excessive whitespace
- Critical images visible
Forms
- Inputs sized for touch
- Labels visible
- Keyboard doesn't obscure inputs
4. Reporting Format
For each issue found:
- Breakpoint: Which viewport(s) affected
- Element: Selector or description
- Issue: What's wrong
- Expected: What should happen
- Fix: Suggested CSS/HTML change
Common Issues & Fixes
Horizontal overflow on mobile
- Check for fixed widths
- Look for images without max-width
- Check for long unbreakable strings
Content hidden on mobile
- Check display:none media queries
- Look for overflow:hidden clipping
Touch targets too small
- Buttons/links need min 44×44px
- Add padding, not just font-size
Text too small
- Base font ≥16px on mobile
- Use clamp() for fluid typography
Principles
- Test real content, not just design
- Consider landscape orientations
- Check both portrait and landscape
- Test with actual touch (if possible)
- Verify JavaScript features work at all sizes
