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)

• 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

• 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
