+
+# 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

+| `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) |

+
+---
+
+## 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 |
+
+---
+

+
+1. Definitions. "You" (or "Your") shall mean the copyright owner or legal entity authorized by the copyright owner that is making this Agreement with Donut Browser. For legal entities, the entity making a Contribution and all other entities that control, are controlled by, or are under common control with that entity are considered to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. "Contribution" shall mean any work, as well as any modifications or additions to an existing work, that is intentionally submitted by You to Donut Browser for inclusion in, or documentation of, any of the products owned or managed by Donut Browser (the "Work"). For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to Donut Browser or its representatives, including but not limited to communication on electronic mailing lists, source code control systems (such as GitHub), and issue tracking systems that are managed by, or on behalf of, Donut Browser for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."
+2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Donut Browser and to recipients of software distributed by Donut Browser a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works under any license terms, including but not limited to the GNU Affero General Public License version 3 (AGPL-3.0) and any commercial or proprietary license terms that Donut Browser may choose to offer. This grant includes the right for Donut Browser to offer the Work, including Your Contributions, under multiple licenses simultaneously (dual or multi-licensing), including both open source and commercial licenses.
+3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Donut Browser and to recipients of software distributed by Donut Browser a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) were submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
+4. You represent that You are legally entitled to grant the above license. If You are an individual, and if Your employer(s) has rights to intellectual property that you create that includes Your Contributions, you represent that You have received permission to make Contributions on behalf of that employer, or that Your employer has waived such rights for your Contributions to Donut Browser. If You are a Corporation, any individual who makes a contribution from an account associated with You will be considered authorized to Contribute on Your behalf.
+5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of others).
+6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support. You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
+7. Should You wish to submit work that is not Your original creation, You may submit it to Donut Browser separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
