Design System

Setup

On first use, read setup.md for integration guidelines. All preferences are stored in ~/design-system/memory.md.

When to Use

User needs to create, maintain, or extend a design system. Agent handles token architecture, component patterns, documentation structure, and cross-platform consistency.

Architecture

Memory lives in ~/design-system/. See memory-template.md for structure.

~/design-system/
├── memory.md         # Status + context + decisions
└── tokens/           # Token definitions if exported

Quick Reference

Core Rules

1. Tokens First, Components Second

Design tokens are the foundation. Before building any component:

• Define color tokens (semantic, not raw hex)
• Define spacing scale (consistent multiplier)
• Define typography scale (modular)

Components consume tokens. Never hardcode values.

2. Semantic Over Literal Naming

Semantic names survive rebrand. Literal names break everything.

3. Three-Tier Token Architecture

Primitive → Semantic → Component
   ↓           ↓          ↓
 gray-900   text-primary  button-text

• Primitive: Raw values (colors, sizes)
• Semantic: Meaning-based (primary, danger, muted)
• Component: Specific use (button-bg, card-border)

4. Document Decisions, Not Just Specs

Every token and component needs:

• What: The value or pattern
• When: Usage context
• Why: The decision behind it
• When NOT: Anti-patterns to avoid

5. Platform-Agnostic Source of Truth

Design tokens should export to:

• CSS custom properties
• Tailwind config
• iOS/Android native
• Figma variables

One source, many outputs. Use Style Dictionary or similar.

6. Component API Consistency

All components follow the same patterns:

• Same prop naming (variant, size, disabled)
• Same size scale (sm, md, lg)
• Same variant names (primary, secondary, ghost)

Predictability beats cleverness.

7. Versioning and Migration

Breaking changes need:

• Version bump (semver)
• Migration guide
• Deprecation warnings before removal
• Codemods when possible

Common Traps

• Premature abstraction → Build 3 instances before extracting a pattern
• Token explosion → 50 grays is not a system, it is chaos
• Skipping documentation → Undocumented patterns get reimplemented wrong
• Designing for edge cases first → Cover 80% well before 100% poorly
• No dark mode strategy → Retrofit is 10x harder than planning upfront
• Inconsistent spacing → Use a scale (4px base), not arbitrary values
• Component prop sprawl → More than 10 props means split the component

Security & Privacy

Data that stays local:

• Design decisions in ~/design-system/
• Token definitions and component specs

This skill does NOT:

• Access files outside ~/design-system/
• Make network requests
• Store sensitive data

這個 Skill 質量較好，文件思路清晰、實用性較強。它能幫助你係統地建立設計系統，給出了很好的設計原則和建議。但作為基礎技能缺少使用示例和常見問題解答，部分內容偏理論化，實際動手時可能需要額外參考資料。對於想要認真建設設計系統的使用者來說，這是一個不錯的起點，但建議搭配其他專項技能一起使用效果更好。
