When to Apply
Use this skill when the task involves UI structure, visual design decisions, interaction patterns, or user experience quality control.
Must Use
- Designing new pages (Landing Page, Dashboard, Admin, SaaS, Mobile App)
- Creating or refactoring UI components (buttons, modals, forms, tables, charts)
- Choosing color schemes, typography systems, spacing standards, or layout systems
- Reviewing UI code for accessibility or visual consistency
- Implementing navigation structures, animations, or responsive behavior
- Making product-level design decisions (style, information hierarchy, brand)
- Improving perceived quality, clarity, or usability of interfaces
Skip
- Pure backend logic development
- API or database design only
- Performance optimization unrelated to the interface
- Infrastructure or DevOps work
Rule: If the task changes how a feature looks, feels, moves, or is interacted with → use this skill.
How to Use (Step by Step)
Step 1: Identify the Task Domain
Run a search to get relevant design context before generating UI code:
# Get style recommendations for a product type
python3 <skill_dir>/scripts/search.py "SaaS dashboard" --domain product
# Get color palette
python3 <skill_dir>/scripts/search.py "fintech app" --domain color
# Get font pairing
python3 <skill_dir>/scripts/search.py "modern minimal" --domain typography
# Generate a full design system
python3 <skill_dir>/scripts/search.py "fitness tracking app" --design-system -p "FitTrack"
Step 2: Apply Results
Use the search results to inform your design decisions. The search returns prioritized, ranked results from the database.
Step 3: Quality Check Against Priority Rules
| Priority | Category | Key Checks |
|---|---|---|
| 1 | Accessibility | Contrast 4.5:1, Alt text, Keyboard nav, Aria-labels |
| 2 | Touch & Interaction | Min 44×44px targets, Loading feedback |
| 3 | Performance | WebP/AVIF, Lazy loading, CLS < 0.1 |
| 4 | Style Selection | Match product type, Consistency, SVG icons |
| 5 | Layout & Responsive | Mobile-first, No horizontal scroll |
| 6 | Typography & Color | Base 16px, Line-height 1.5, Semantic tokens |
| 7 | Animation | 150–300ms duration, transform/opacity only |
| 8 | Forms & Feedback | Visible labels, Error near field |
| 9 | Navigation | Predictable back, Bottom nav ≤5 items |
| 10 | Charts & Data | Legends, Tooltips, Accessible colors |
Quick Reference
Accessibility (CRITICAL)
- Minimum 4.5:1 contrast ratio for normal text
- Visible focus rings on all interactive elements
- Descriptive alt text for meaningful images
- aria-labels for icon-only buttons
- Tab order matches visual order
- Support
prefers-reduced-motion
Touch & Interaction (CRITICAL)
- Min 44×44pt (Apple) / 48×48dp (Material) touch targets
- Minimum 8px gap between touch targets
- Use click/tap for primary interactions, not hover-only
- Disable button + show spinner during async operations
- Add
cursor-pointerto clickable elements
Performance (HIGH)
- Use WebP/AVIF + responsive
srcset - Declare
width/heightto prevent CLS font-display: swapto avoid FOIT- Lazy load below-fold images
- Virtualize lists with 50+ items
Style Selection (HIGH)
- Match style to product type (run
--domain product) - Use SVG icons (Heroicons, Lucide) — never emoji as icons
- One icon set/visual language across the product
- Each screen has only one primary CTA
Layout & Responsive (HIGH)
width=device-width, initial-scale=1viewport meta- Design mobile-first: 375 → 768 → 1024 → 1440
- No horizontal scroll on mobile
- Use 4pt/8dp spacing scale
min-h-dvhinstead of100vhon mobile
Typography & Color (MEDIUM)
- Minimum 16px body text (avoids iOS auto-zoom)
- Line height 1.5–1.75 for body text
- 65–75 chars per line on desktop
- Use semantic color tokens, not raw hex in components
- Bold headings (600–700), Regular body (400), Medium labels (500)
Animation (MEDIUM)
- 150–300ms for micro-interactions
- Use
transform/opacityonly — never animatewidth/height - Respect
prefers-reduced-motion - Exit animations 60–70% of enter duration
- Every animation must convey meaning, not just decoration
Forms & Feedback (MEDIUM)
- Visible label per input (not placeholder-only)
- Show error below the related field
- Validate on blur, not keystroke
- Confirm before destructive actions
- Auto-dismiss toasts in 3–5s
Navigation (HIGH)
- Bottom nav max 5 items with labels
- Back navigation must be predictable
- All key screens reachable via deep link
- State preservation when navigating back
Charts & Data (LOW)
- Match chart type to data type (trend → line, comparison → bar)
- Always show legend near chart
- Provide tooltips on hover/tap
- Use accessible color palettes (not red/green only)
