+
+# UI/UX Pro Max - Design Intelligence
+
+Searchable database of UI styles, color palettes, font pairings, chart types, product recommendations, UX guidelines, and stack-specific best practices.
+
+## 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: Search Relevant Domains
+
+Use `search.py` multiple times to gather comprehensive information. Search until you have enough context.
+
+```bash
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "<keyword>" --domain <domain> [-n <max_results>]
+```
+
+**Recommended search order:**
+
+1. **Product** - Get style recommendations for product type
+2. **Style** - Get detailed style guide (colors, effects, frameworks)
+3. **Typography** - Get font pairings with Google Fonts imports
+4. **Color** - Get color palette (Primary, Secondary, CTA, Background, Text, Border)
+5. **Landing** - Get page structure (if landing page)
+6. **Chart** - Get chart recommendations (if dashboard/analytics)
+7. **UX** - Get best practices and anti-patterns
+8. **Stack** - Get stack-specific guidelines (default: html-tailwind)
+
+### Step 3: Stack Guidelines (Default: html-tailwind)
+
+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`
+
+---
+
+## Search Reference
+
+### Available Domains
+
+| Domain | Use For | Example Keywords |
+|--------|---------|------------------|
+| `product` | Product type recommendations | SaaS, e-commerce, portfolio, healthcare, beauty, service |
+| `style` | UI styles, colors, effects | glassmorphism, minimalism, dark mode, brutalism |
+| `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 |
+| `prompt` | AI prompts, CSS keywords | (style name) |
+
+### Available Stacks
+
+| Stack | Focus |
+|-------|-------|
+| `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 |
+
+---
+
+## Example Workflow
+
+**User request:** "Làm landing page cho dịch vụ chăm sóc da chuyên nghiệp"
+
+**AI should:**
+
+```bash
+# 1. Search product type
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness service" --domain product
+
+# 2. Search style (based on industry: beauty, elegant)
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "elegant minimal soft" --domain style
+
+# 3. Search typography
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "elegant luxury" --domain typography
+
+# 4. Search color palette
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "beauty spa wellness" --domain color
+
+# 5. Search landing page structure
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "hero-centric social-proof" --domain landing
+
+# 6. Search UX guidelines
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "animation" --domain ux
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "accessibility" --domain ux
+
+# 7. Search stack guidelines (default: html-tailwind)
+python3 .claude/skills/ui-ux-pro-max/scripts/search.py "layout responsive" --stack html-tailwind
+```
+
+**Then:** Synthesize all search results and implement the design.
+
+---
+
+## 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 |
+
+---
+
+## Pre-Delivery Checklist

+- [ ] Hover states provide clear visual feedback
+- [ ] Transitions are smooth (150-300ms)
+- [ ] Focus states visible for keyboard navigation
+
+### Light/Dark Mode
+- [ ] Light mode text has sufficient contrast (4.5:1 minimum)
+- [ ] Glass/transparent elements visible in light mode
+- [ ] Borders visible in both modes
+- [ ] Test both modes before delivery
+
+### Layout

+If you are looking for a cloud-based platform to deploy your NestJS application, check out [Mau](https://mau.nestjs.com), our official platform for deploying NestJS applications on AWS. Mau makes deployment straightforward and fast, requiring just a few simple steps:
+
+```bash
+$ pnpm install -g @nestjs/mau
+$ mau deploy
+```
+
+With Mau, you can deploy your application in just a few clicks, allowing you to focus on building features rather than managing infrastructure.
