# UI/UX Pro Max - Design Intelligence

Searchable database: 50+ styles, 97 color palettes, 57 font pairings, 99 UX guidelines, 25 chart types across 9 stacks.

## Pre-check (K1)

> Does this project need custom UI/UX design? If using a pre-built template or admin framework (e.g., Retool, Vercel templates), skip this skill.

## Rule Categories by Priority

| Priority | Category | Impact | Domain |
|----------|----------|--------|--------|
| 1 | Accessibility | CRITICAL | `ux` |
| 2 | Touch & Interaction | CRITICAL | `ux` |
| 3 | Performance | HIGH | `ux` |
| 4 | Layout & Responsive | HIGH | `ux` |
| 5 | Typography & Color | MEDIUM | `typography`, `color` |
| 6 | Animation | MEDIUM | `ux` |
| 7 | Style Selection | MEDIUM | `style`, `product` |
| 8 | Charts & Data | LOW | `chart` |

## Quick Reference

### 1. Accessibility (CRITICAL)

- `color-contrast` - Minimum 4.5:1 ratio for normal text
- `focus-states` - Visible focus rings on interactive elements
- `alt-text` - Descriptive alt text for meaningful images
- `aria-labels` - aria-label for icon-only buttons
- `keyboard-nav` - Tab order matches visual order
- `form-labels` - Use label with for attribute

### 2. Touch & Interaction (CRITICAL)

- `touch-target-size` - Minimum 44x44px touch targets
- `hover-vs-tap` - Use click/tap for primary interactions
- `loading-buttons` - Disable button during async operations
- `error-feedback` - Clear error messages near problem
- `cursor-pointer` - Add cursor-pointer to clickable elements

### 3. Performance (HIGH)

- `image-optimization` - Use WebP, srcset, lazy loading
- `reduced-motion` - Check prefers-reduced-motion
- `content-jumping` - Reserve space for async content

### 4. Layout & Responsive (HIGH)

- `viewport-meta` - width=device-width initial-scale=1
- `readable-font-size` - Minimum 16px body text on mobile
- `horizontal-scroll` - Ensure content fits viewport width
- `z-index-management` - Define z-index scale (10, 20, 30, 50)

### 5. Typography & Color (MEDIUM)

- `line-height` - Use 1.5-1.75 for body text
- `line-length` - Limit to 65-75 characters per line
- `font-pairing` - Match heading/body font personalities

### 6. Animation (MEDIUM)

- `duration-timing` - Use 150-300ms for micro-interactions
- `transform-performance` - Use transform/opacity, not width/height
- `loading-states` - Skeleton screens or spinners

### 7. Style Selection (MEDIUM)

- `style-match` - Match style to product type
- `consistency` - Use same style across all pages
- `no-emoji-icons` - Use SVG icons, not emojis

### 8. Charts & Data (LOW)

- `chart-type` - Match chart type to data type
- `color-guidance` - Use accessible color palettes
- `data-table` - Provide table alternative for accessibility

## How to Use

### Step 1: Analyze Requirements

Extract from user request: **product type**, **style keywords**, **industry**, **stack** (default: html-tailwind).

### Step 2: Generate Design System (REQUIRED)

```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<product_type> <industry> <keywords>" --design-system [-p "Project Name"]
```

This searches 5 domains in parallel (product, style, color, landing, typography), applies reasoning rules, and returns complete design system.

**Persist for cross-session use:**
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name"
```

Creates `design-system/MASTER.md` (global) + optional `design-system/pages/<page>.md` (overrides).

**With page-specific override:**
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Name" --page "dashboard"
```

**Hierarchical retrieval**: Page file overrides Master. No page file → Master exclusively.

### Step 3: Detailed Searches (as needed)

```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]
```

Domains: `product`, `style`, `typography`, `color`, `landing`, `chart`, `ux`, `react`, `web`, `prompt`

### Step 4: Stack Guidelines (default: html-tailwind)

```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<keyword>" --stack html-tailwind
```

Stacks: `html-tailwind`, `react`, `nextjs`, `vue`, `svelte`, `swiftui`, `react-native`, `flutter`, `shadcn`, `jetpack-compose`

## Common Rules for Professional UI

### Icons & Visual Elements

| Rule | Do | Don't |
|------|----|----- |
| **No emoji icons** | Use SVG icons (Heroicons, Lucide, Simple Icons) | Use emojis as UI icons |
| **Stable hover states** | Use color/opacity transitions on hover | Use scale transforms that shift layout |
| **Correct brand logos** | Research official SVG from Simple Icons | Guess or use incorrect logo paths |
| **Consistent icon sizing** | Fixed viewBox (24x24) with w-6 h-6 | Mix different icon sizes |

### Interaction & Cursor

| Rule | Do | Don't |
|------|----|----- |
| **Cursor pointer** | `cursor-pointer` on all clickable elements | Default cursor on interactive elements |
| **Hover feedback** | Visual feedback (color, shadow, border) | No indication element is interactive |
| **Smooth transitions** | `transition-colors duration-200` | Instant changes or >500ms |

### Light/Dark Mode Contrast

| Rule | Do | Don't |
|------|----|----- |
| **Glass card light mode** | `bg-white/80` or higher opacity | `bg-white/10` (too transparent) |
| **Text contrast light** | `#0F172A` (slate-900) for text | `#94A3B8` (slate-400) for body |
| **Muted text light** | `#475569` (slate-600) minimum | gray-400 or lighter |
| **Border visibility** | `border-gray-200` in light mode | `border-white/10` (invisible) |

### Layout & Spacing

| Rule | Do | Don't |
|------|----|----- |
| **Floating navbar** | `top-4 left-4 right-4` spacing | Stick to `top-0 left-0 right-0` |
| **Content padding** | Account for fixed navbar height | Content hidden behind fixed elements |
| **Consistent max-width** | Same `max-w-6xl` or `max-w-7xl` | Mix different container widths |

## Design Direction Anti-Patterns

Avoid these signs of generic, AI-generated UI:

| Anti-Pattern | Fix |
|---|---|
| Default Bootstrap/Tailwind without customization | Define design tokens first (colors, typography, spacing, motion) |
| Overused fonts (Inter, Roboto) without styling | Choose distinctive typefaces that set the tone |
| Predictable card-based layouts everywhere | Use asymmetry and unconventional layouts when appropriate |
| Stock photography without curation | Custom icons and illustrations |
| Safe, corporate color palettes | Develop unique color palettes beyond defaults |
| No micro-interactions | Add meaningful motion to guide user attention (150-300ms) |
