• loading-states - Skeleton screens or spinners

7. Style Selection (MEDIUM)

• style-match - Match style to product type
• consistency - Use same style across all pages

How to Use

Search specific domains using the CLI tool below.

Prerequisites

Check if Python is installed:

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:

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

Interaction & Cursor

Light/Dark Mode Contrast

Layout & Spacing

Pre-Delivery Checklist

Before delivering UI code, verify these items:

Visual Quality

• No emojis used as icons (use SVG instead)
• All icons from consistent icon set (Heroicons/Lucide)
• Brand logos are correct (verified from Simple Icons)
• Hover states don't cause layout shift
• Use theme colors directly (bg-primary) not var() wrapper

Interaction

• All clickable elements have cursor-pointer
• 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

• Floating elements have proper spacing from edges
• No content hidden behind fixed navbars
• Responsive at 375px, 768px, 1024px, 1440px
• No horizontal scroll on mobile

Accessibility

• All images have alt text
• Form inputs have labels
• Color is not the only indicator
• prefers-reduced-motion respected
