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: Design System 생성

위 Quick Reference와 아래 데이터를 기반으로 디자인 시스템을 직접 구성합니다:

스타일 선택: 제품 유형 + 산업에 맞는 스타일 (glassmorphism, minimalism, brutalism 등)
색상 팔레트: 산업별 추천 팔레트 매칭
타이포그래피: 스타일에 맞는 폰트 페어링 선택
레이아웃 패턴: 제품 유형에 맞는 레이아웃 구조

산업별 스타일 매칭

산업	추천 스타일	색상 톤	폰트 성격
SaaS/Tech	Minimalism, Flat Design	Blue/Purple 계열	Geometric Sans (Inter, Geist)
E-commerce	Clean, Card-based	Warm neutral	Readable (Plus Jakarta Sans)
Healthcare	Soft, Trustworthy	Green/Teal 계열	Humanist Sans (Source Sans)
Fintech	Professional, Data-rich	Navy/Gold 계열	Monospace accent (JetBrains Mono)
Beauty/Wellness	Elegant, Soft	Rose/Sage 계열	Serif accent (Playfair Display)
Gaming	Dark, Vibrant	Neon/Dark 계열	Display (Orbitron, Rajdhani)
Education	Friendly, Accessible	Bright primary	Rounded (Nunito, Quicksand)
Portfolio	Expressive, Unique	Monochrome + accent	Display mix

폰트 페어링 (Google Fonts)

조합	Heading	Body	분위기
Modern Pro	Inter	Inter	깔끔, 프로페셔널
Elegant	Playfair Display	Lato	고급, 세련

Step 3: Stack별 가이드라인 적용

Stack	핵심 패턴
html-tailwind	Tailwind utilities, responsive, a11y (DEFAULT)
react	State, hooks, performance, patterns
nextjs	SSR, routing, images, API routes
vue	Composition API, Pinia, Vue Router
svelte	Runes, stores, SvelteKit
shadcn	shadcn/ui 컴포넌트, 테마, 폼, 패턴

Step 4: 구현 + Pre-Delivery Checklist 검증

shadcn/ui MCP 도구가 사용 가능하면 컴포넌트 검색 및 예시를 활용합니다.

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
