About this skill

Svelte UI Design System

Svelte 5 + Tailwind CSS 4 + Skeleton Labs + Bits UI 통합 디자인 시스템

When to Use This Skill

자동 활성화:

  • ANY Svelte component creation or modification
  • ALL styling, design, and UI work in Svelte projects
  • Component props, layouts, colors, spacing, typography
  • Forms, buttons, cards, chips, badges, tables, dialogs, overlays
  • Animations, transitions, hover effects, responsive design
  • Dark mode, themes, conditional styling, dynamic values

Core Principles

  1. 컴포넌트: Bits UI headless 컴포넌트만 사용
  2. 스타일링:
    • Skeleton Labs 토큰/프리셋 (preset-filled, preset-tonal 등)
    • Skeleton Labs Tailwind Components (card, chip, badge, placeholder 등 - 클래스 조합)
    • Tailwind CSS 유틸리티
  3. Skeleton 색상/프리셋: 반드시 공식 문서 참고, 직접 shade 조합 만들지 말 것
  4. Progressive disclosure: 필요한 문서만 참조
  5. 1-level deep 참조: SKILL.md → reference 파일만

Quick Reference

Skeleton Labs 중요 규칙

Color Pairings (반드시 colors-design.md 참고):

  • 패턴: {property}-{color}-{lightShade}-{darkShade}
  • 허용 조합: 50-950, 100-900, 200-800, 300-700, 400-600, 500, 600-400, 700-300, 800-200, 900-100, 950-50
  • 규칙: 두 shade의 합이 1000 또는 500 단독
  • 예: bg-surface-50-950, text-primary-200-800

Presets (반드시 presets-design.md 참고):

  • Filled: preset-filled-{color}-{lightShade}-{darkShade} 또는 preset-filled-{color}-500
  • Tonal: preset-tonal-{color}
  • Outlined: preset-outlined-{color}-{lightShade}-{darkShade}

Svelte 5 Class Composition

<!-- Array form -->
<div class={['base', condition && 'extra']}>

<!-- Object form -->
<div class={{ 'active': isActive, 'disabled': !enabled }}>

<!-- Style directive for dynamic values -->
<div
  class="bg-(--brand-color)"
  style:--brand-color={dynamicValue}>

Usage Pattern

<script lang="ts">
  import { Dialog } from "bits-ui";
</script>

<Dialog.Root>
  <Dialog.Trigger class="btn preset-filled-primary-500">
    Open
  </Dialog.Trigger>
  <Dialog.Content class={[
    'card preset-filled-surface-50-950',
    'p-8 rounded-xl shadow-xl'
  ]}>
    <Dialog.Title class="h3 text-primary-600-400">
      Title
    </Dialog.Title>
  </Dialog.Content>
</Dialog.Root>

Best Practices

  1. 컴포넌트: Bits UI headless 컴포넌트만 사용
  2. 스타일링: Skeleton Labs 토큰/프리셋 + Tailwind Components (card, chip, badge 등) + Tailwind 유틸리티
  3. Skeleton 색상/프리셋: 반드시 공식 문서(colors-design.md, presets-design.md)에서 확인
  4. Class 조합 순서: Tailwind Components → 프리셋 → 레이아웃 → 간격 → 조건부 → variant
  5. 접근성: WCAG 대비 비율, focus-visible 상태
  6. 성능: Svelte class 배열/객체 사용, Skeleton 프리셋 활용
  7. 일관성: 동일한 용어 사용, 3인칭 작성

When not to use it

  • Non-Svelte projects
  • Plain HTML/CSS static pages without build tools
  • Legacy Svelte 3/4 applications without migration path
