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:

Searches 5 domains in parallel (product, style, color, landing, typography)
Applies reasoning rules from ui-reasoning.csv to select best matches
Returns complete design system: pattern, style, colors, typography, effects
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

Be specific with keywords - "healthcare SaaS dashboard" > "app"
Search multiple times - Different keywords reveal different insights
Combine domains - Style + Typography + Color = Complete design system
Always check UX - Search "animation", "z-index", "accessibility" for common issues
Use stack flag - Get implementation-specific best practices
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

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
