UI/UX Pro Max - Design Intelligence
Overview
Systematic design guide with priority-based UX rules, accessibility requirements, and pre-delivery checklists. Use alongside @designing-frontends for creative direction.
Core principle: Apply rules by priority (CRITICAL → HIGH → MEDIUM → LOW) and verify with checklist before delivery.
When to Use
- Building UI components that need accessibility compliance
- Reviewing code for UX issues (touch targets, focus states, contrast)
- Implementing responsive layouts
- Adding animations and interactions
- Preparing UI for production delivery
- Choosing typography, colors, or chart types systematically
Use @designing-frontends for: Creative direction, bold aesthetics, unique visual identity
Use @ui-ux-pro-max for: Systematic rules, accessibility, checklists, production polish

Design Reference Data
This skill includes comprehensive design databases in the data/ folder:
Available References
data/styles.md - 68 design styles with colors, effects, CSS implementation
data/colors.md - 96 color palettes by product type (SaaS, e-commerce, healthcare, etc.)
data/typography.md - 57 font pairings with Google Fonts imports and Tailwind config
How to Use
When building UI, read the relevant data file for recommendations:
- Need a style? → Read
data/styles.md for Glassmorphism, Neubrutalism, Bento Grid, etc.
- Need colors? → Read
data/colors.md for product-specific palettes
- Need fonts? → Read
data/typography.md for curated pairings with imports
Example Workflow
- User asks for "fintech dashboard"
- Read
data/colors.md → Find "Financial Dashboard" palette
- Read
data/styles.md → Find "Data-Dense Dashboard" or "Executive Dashboard" style
- Read
data/typography.md → Find "Financial Trust" or "Dashboard Data" pairing
- Apply the recommendations with the UX rules from this skill
Tips for Better Results
- Be specific - "healthcare SaaS dashboard" > "app"
- Check accessibility first - CRITICAL rules before polish
- Test both modes - Light and dark before delivery
- Use the checklist - Run through every item before shipping
Common Mistakes
| Mistake | Fix |
|---|
Missing cursor-pointer on buttons | Add to all clickable elements |
| Low contrast in light mode | Test with contrast checker (4.5:1 minimum) |
| Emojis as icons | Replace with SVG from Lucide/Heroicons |
| Touch targets too small | Ensure minimum 44x44px |
| No loading states | Add skeleton or spinner for async |
