# UI/UX Pro Max - Design Intelligence

BM25 search engine-based UI/UX design intelligence for style, color, typography, layout, and UX decisions.

## When to Apply

Reference these guidelines when:
- Designing new UI components or pages
- Choosing color palettes and typography
- Reviewing code for UX issues
- Building landing pages or dashboards
- Implementing accessibility requirements

## 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

## Prerequisites

Check if Python is installed:

```bash
python3 --version || python --version
```

## How to Use This Skill

When user requests UI/UX work (design, build, create, implement, review, fix, improve), follow this workflow:

### Step 1: Analyze User Requirements

Extract key information from user request:
- **Product type**: SaaS, e-commerce, portfolio, dashboard, landing page, etc.
- **Style keywords**: minimal, playful, professional, elegant, dark mode, etc.
- **Industry**: healthcare, fintech, gaming, education, etc.
- **Stack**: React, Vue, Next.js, or default to `html-tailwind`

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

**Always start with `--design-system`** to get comprehensive recommendations with reasoning:

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

This command:
1. Searches 5 domains in parallel (product, style, color, landing, typography)
2. Applies reasoning rules from `ui-reasoning.csv` to select best matches
3. Returns complete design system: pattern, style, colors, typography, effects
4. Includes anti-patterns to avoid

**Example:**
```bash
python3 skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service elegant" --design-system -p "Serenity Spa"
```

### Step 2b: Persist Design System (Master + Overrides Pattern)

To save the design system for hierarchical retrieval across sessions, add `--persist`:

```bash
python3 skills/ui-ux-pro-max/scripts/search.py "<query>" --design-system --persist -p "Project Name"
```

This creates:
- `design-system/MASTER.md` - Global Source of Truth with all design rules
- `design-system/pages/` - Folder for page-specific overrides

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

**How hierarchical retrieval works:**
1. When building a specific page (e.g., "Checkout"), first check `design-system/pages/checkout.md`
2. If the page file exists, its rules **override** the Master file
3. If not, use `design-system/MASTER.md` exclusively

### Step 2c: Use Existing DESIGN.md (Google Stitch Format)

If the project already has a `DESIGN.md` in the root (e.g., from [awesome-design-md](https://github.com/VoltAgent/awesome-design-md)), **skip design system generation** and use it directly. DESIGN.md follows the 9-section Stitch format (visual theme, colors, typography, components, layout, depth, do/don'ts, responsive, agent prompts) and serves as the single source of truth for all UI decisions.

**Install a brand DESIGN.md:**
```bash
npx getdesign@latest add {brand}     # e.g., vercel, stripe, linear.app
npx getdesign@latest list             # show all 66 available brands
```

**Available brands**: airbnb, apple, claude, cursor, figma, linear.app, notion, stripe, supabase, tesla, vercel, and 55 more.

**Template**: Use `templates/visual-design.template.md` to create a custom DESIGN.md from scratch.

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

After getting the design system, use domain searches to get additional details:

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

**When to use detailed searches:**

| Need | Domain | Example |
|------|--------|---------|
| More style options | `style` | `--domain style "glassmorphism dark"` |
| Chart recommendations | `chart` | `--domain chart "real-time dashboard"` |
| UX best practices | `ux` | `--domain ux "animation accessibility"` |
| Alternative fonts | `typography` | `--domain typography "elegant luxury"` |
| Landing structure | `landing` | `--domain landing "hero social-proof"` |

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

Get implementation-specific best practices. If user doesn't specify a stack, **default to `html-tailwind`**.

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

Available stacks: `html-tailwind`, `react`, `nextjs`, `astro`, `vue`, `nuxtjs`, `nuxt-ui`, `svelte`, `swiftui`, `react-native`, `flutter`, `shadcn`, `jetpack-compose`

python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system

# Markdown - best for documentation
python3 skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system -f markdown
```

## 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** | Use fixed viewBox (24x24) with w-6 h-6 | Mix different icon sizes randomly |

### Interaction & Cursor

| Rule | Do | Don't |
|------|----|----- |
| **Cursor pointer** | Add `cursor-pointer` to all clickable elements | Leave default cursor on interactive elements |
| **Hover feedback** | Provide visual feedback (color, shadow, border) | No indication element is interactive |
| **Smooth transitions** | Use `transition-colors duration-200` | Instant state changes or too slow (>500ms) |

### Light/Dark Mode Contrast

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