Use when creating design tokens, implementing theme switching, building component libraries, or establishing design system foundations.</h2>\n<h1>Design System Patterns</h1>\n<p>Master design system architecture to create consistent, maintainable, and scalable UI foundations across web and mobile applications.</p>\n<h2>When to Use This Skill</h2>\n<ul>\n<li>Creating design tokens for colors, typography, spacing, and shadows</li>\n<li>Implementing light/dark theme switching with CSS custom properties</li>\n<li>Building multi-brand theming systems</li>\n<li>Architecting component libraries with consistent APIs</li>\n<li>Establishing design-to-code workflows with Figma tokens</li>\n<li>Creating semantic token hierarchies (primitive, semantic, component)</li>\n<li>Setting up design system documentation and guidelines</li>\n</ul>\n<h2>Core Capabilities</h2>\n<h3>1. Design Tokens</h3>\n<ul>\n<li>Primitive tokens (raw values: colors, sizes, fonts)</li>\n<li>Semantic tokens (contextual meaning: text-primary, surface-elevated)</li>\n<li>Component tokens (specific usage: button-bg, card-border)</li>\n<li>Token naming conventions and organization</li>\n<li>Multi-platform token generation (CSS, iOS, Android)</li>\n</ul>\n<h3>2. Theming Infrastructure</h3>\n<ul>\n<li>CSS custom properties architecture</li>\n<li>Theme context providers in React</li>\n<li>Dynamic theme switching</li>\n<li>System preference detection (prefers-color-scheme)</li>\n<li>Persistent theme storage</li>\n<li>Reduced motion and high contrast modes</li>\n</ul>\n<h3>3. Component Architecture</h3>\n<ul>\n<li>Compound component patterns</li>\n<li>Polymorphic components (as prop)</li>\n<li>Variant and size systems</li>\n<li>Slot-based composition</li>\n<li>Headless UI patterns</li>\n<li>Style props and responsive variants</li>\n</ul>\n<h3>4. Token Pipeline</h3>\n<ul>\n<li>Figma to code synchronization</li>\n<li>Style Dictionary configuration</li>\n<li>Token transformation and formatting</li>\n<li>CI/CD integration for token updates</li>\n</ul>\n<h2>Quick Start</h2>\n<pre><code>// Design tokens with CSS custom properties\nconst tokens = {\n  colors: {\n    // Primitive tokens\n    gray: {\n      50: \"#fafafa\",\n      100: \"#f5f5f5\",\n      900: \"#171717\",\n    },\n    blue: {\n      500: \"#3b82f6\",\n      600: \"#2563eb\",\n    },\n  },\n  // Semantic tokens (reference primitives)\n  semantic: {\n    light: {\n      \"text-primary\": \"var(--color-gray-900)\",\n      \"text-secondary\": \"var(--color-gray-600)\",\n      \"surface-default\": \"var(--color-white)\",\n      \"surface-elevated\": \"var(--color-gray-50)\",\n      \"border-default\": \"var(--color-gray-200)\",\n      \"interactive-primary\": \"var(--color-blue-500)\",\n    },\n    dark: {\n      \"text-primary\": \"var(--color-gray-50)\",\n      \"text-secondary\": \"var(--color-gray-400)\",\n      \"surface-default\": \"var(--color-gray-900)\",\n      \"surface-elevated\": \"var(--color-gray-800)\",\n      \"border-default\": \"var(--color-gray-700)\",\n      \"interactive-primary\": \"var(--color-blue-400)\",\n    },\n  },\n};\n</code></pre>\n<h2>Detailed patterns and worked examples</h2>\n<p>Detailed pattern documentation lives in <code>references/details.md</code>. Read that file when the navigation tier above is insufficient.</p>\n<h2>Best Practices</h2>\n<ol>\n<li><strong>Name Tokens by Purpose</strong>: Use semantic names (text-primary) not visual descriptions (dark-gray)</li>\n<li><strong>Maintain Token Hierarchy</strong>: Primitives &gt; Semantic &gt; Component tokens</li>\n<li><strong>Document Token Usage</strong>: Include usage guidelines with token definitions</li>\n<li><strong>Version Tokens</strong>: Treat token changes as API changes with semver</li>\n<li><strong>Test Theme Combinations</strong>: Verify all themes work with all components</li>\n<li><strong>Automate Token Pipeline</strong>: CI/CD for Figma-to-code synchronization</li>\n<li><strong>Provide Migration Paths</strong>: Deprecate tokens gradually with clear alternatives</li>\n</ol>\n<h2>Common Issues</h2>\n<ul>\n<li><strong>Token Sprawl</strong>: Too many tokens without clear hierarchy</li>\n<li><strong>Inconsistent Naming</strong>: Mixed conventions (camelCase vs kebab-case)</li>\n<li><strong>Missing Dark Mode</strong>: Tokens that don't adapt to theme changes</li>\n<li><strong>Hardcoded Values</strong>: Using raw values instead of tokens</li>\n<li><strong>Circular References</strong>: Tokens referencing each other in loops</li>\n<li><strong>Platform Gaps</strong>: Tokens missing for some platforms (web but not mobile)</li>\n</ul>\n","files":[{"path":"references/component-architecture.md","sizeBytes":15293,"isText":true},{"path":"references/design-tokens.md","sizeBytes":11269,"isText":true},{"path":"references/details.md","sizeBytes":5566,"isText":true},{"path":"references/theming-architecture.md","sizeBytes":12365,"isText":true},{"path":"SKILL.md","sizeBytes":4003,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
