python3 --version || python --version

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

macOS:

brew install python3

Ubuntu/Debian:

sudo apt update && sudo apt install python3

Windows:

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:

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:

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:

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.

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

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)

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)

# 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

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:

# 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 |
