## Rule Categories by Priority

| Priority | Category | Impact | Domain |
|----------|----------|--------|--------|
| 1 | Accessibility | CRITICAL | `ux` |
| 2 | Touch & Interaction | CRITICAL | `ux` |

## 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

- `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)

- `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)

- `data-table` - Provide table alternative for accessibility

## How to Use

Search specific domains using the CLI tool below.

---

## Prerequisites

Check if Python is installed:

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

If Python is not installed, install it based on user's OS:

**macOS:**
```bash
brew install python3
```

**Ubuntu/Debian:**
```bash
sudo apt update && sudo apt install python3
```

**Windows:**
```powershell
winget install Python.Python.3.12
```

---

## 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 .agents/skills/ui_ux_design/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 .agents/skills/ui_ux_design/scripts/search.py "beauty spa wellness service" --design-system -p "Serenity Spa"
```

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

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

```bash
python3 .agents/skills/ui_ux_design/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 .agents/skills/ui_ux_design/scripts/search.py "<keyword>" --stack html-tailwind
```

Available stacks: `html-tailwind`, `react`, `nextjs`, `vue`, `svelte`, `swiftui`, `react-native`, `flutter`, `shadcn`

## Example Workflow

**User request:** "Làm landing page cho dịch vụ chăm sóc da chuyên nghiệp"

### Step 1: Analyze Requirements
- Product type: Beauty/Spa service
- Style keywords: elegant, professional, soft
- Industry: Beauty/Wellness
- Stack: html-tailwind (default)

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

```bash
python3 .agents/skills/ui_ux_design/scripts/search.py "beauty spa wellness service elegant" --design-system -p "Serenity Spa"
```

**Output:** Complete design system with pattern, style, colors, typography, effects, and anti-patterns.

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

```bash
# Get UX guidelines for animation and accessibility
python3 .agents/skills/ui_ux_design/scripts/search.py "animation accessibility" --domain ux

# Get alternative typography options if needed
python3 .agents/skills/ui_ux_design/scripts/search.py "elegant luxury serif" --domain typography
```

### Step 4: Stack Guidelines

```bash
python3 .agents/skills/ui_ux_design/scripts/search.py "layout responsive form" --stack html-tailwind
```

**Then:** Synthesize design system + detailed searches and implement the design.

## Output Formats

The `--design-system` flag supports two output formats:

```bash
# ASCII box (default) - best for terminal display
python3 .agents/skills/ui_ux_design/scripts/search.py "fintech crypto" --design-system

# Markdown - best for documentation
python3 .agents/skills/ui_ux_design/scripts/search.py "fintech crypto" --design-system -f markdown
```

## Tips for Better Results

1. **Be specific with keywords** - "healthcare SaaS dashboard" > "app"
2. **Search multiple times** - Different keywords reveal different insights
3. **Combine domains** - Style + Typography + Color = Complete design system
4. **Always check UX** - Search "animation", "z-index", "accessibility" for common issues
5. **Use stack flag** - Get implementation-specific best practices
6. **Iterate** - If first search doesn't match, try different keywords

## Common Rules for Professional UI

These are frequently overlooked issues that make UI look unprofessional:

### Icons & Visual Elements

| Rule | Do | Don't |
|------|----|----- |
| **No emoji icons** | Use SVG icons (Heroicons, Lucide, Simple Icons) | Use emojis like 🎨 🚀 ⚙️ 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/hoverable cards | 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) |

### Layout & Spacing

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