+- `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)
+

+
+## 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 .claude/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 .claude/skills/ui-ux-pro-max/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 .claude/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 .claude/skills/ui-ux-pro-max/scripts/search.py "<keyword>" --stack html-tailwind
+```
+
+Available stacks: `html-tailwind`, `react`, `nextjs`, `vue`, `svelte`, `swiftui`, `react-native`, `flutter`, `shadcn`
+
+---
+
+## Search Reference

+| `typography` | Font pairings, Google Fonts | elegant, playful, professional, modern |
+| `color` | Color palettes by product type | saas, ecommerce, healthcare, beauty, fintech, service |
+| `landing` | Page structure, CTA strategies | hero, hero-centric, testimonial, pricing, social-proof |
+| `chart` | Chart types, library recommendations | trend, comparison, timeline, funnel, pie |
+| `ux` | Best practices, anti-patterns | animation, accessibility, z-index, loading |
+| `react` | React/Next.js performance | waterfall, bundle, suspense, memo, rerender, cache |
+| `web` | Web interface guidelines | aria, focus, keyboard, semantic, virtualize |

+| `html-tailwind` | Tailwind utilities, responsive, a11y (DEFAULT) |
+| `react` | State, hooks, performance, patterns |
+| `nextjs` | SSR, routing, images, API routes |
+| `vue` | Composition API, Pinia, Vue Router |
+| `svelte` | Runes, stores, SvelteKit |
+| `swiftui` | Views, State, Navigation, Animation |
+| `react-native` | Components, Navigation, Lists |
+| `flutter` | Widgets, State, Layout, Theming |
+| `shadcn` | shadcn/ui components, theming, forms, patterns |
+
+---
+
+## 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 .claude/skills/ui-ux-pro-max/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 .claude/skills/ui-ux-pro-max/scripts/search.py "animation accessibility" --domain ux
+
+# Get alternative typography options if needed
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "elegant luxury serif" --domain typography
+```
+
+### Step 4: Stack Guidelines
+
+```bash
+python3 .claude/skills/ui-ux-pro-max/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 .claude/skills/ui-ux-pro-max/scripts/search.py "fintech crypto" --design-system
+
+# Markdown - best for documentation
+python3 .claude/skills/ui-ux-pro-max/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 |
+
