Use <code>styled()</code> with variants for component APIs, <code>$</code>-prefixed tokens for consistent spacing/color, theme nesting for light/dark modes, and the <code>transition</code> prop for animations. The compiler extracts static styles to CSS on web and hoists style objects on native -- but only when props are deterministic at build time.</p>\n</blockquote>\n<hr>\n<p>&lt;critical_requirements&gt;</p>\n<h2>CRITICAL: Before Using This Skill</h2>\n<blockquote>\n<p><strong>All code must follow project conventions in CLAUDE.md</strong> (kebab-case, named exports, import ordering, <code>import type</code>, named constants)</p>\n</blockquote>\n<p><strong>(You MUST use <code>$</code>-prefixed token values in style props (<code>$4</code>, <code>$color.blue</code>) -- raw pixel values bypass the token system and break theme consistency)</strong></p>\n<p><strong>(You MUST keep the <code>transition</code> prop present in JSX when using animations -- conditionally removing it causes expensive hook teardown; pass <code>null</code> to disable instead)</strong></p>\n<p><strong>(You MUST add <code>as const</code> to variant definition objects -- without it TypeScript cannot infer variant prop types correctly)</strong></p>\n<p><strong>(You MUST use <code>Adapt</code> for responsive Dialog-to-Sheet behavior -- manual Platform.OS branching breaks compiler optimization and misses breakpoint changes)</strong></p>\n<p>&lt;/critical_requirements&gt;</p>\n<hr>\n<p><strong>Auto-detection:</strong> Tamagui, tamagui, styled(), createTamagui, createTokens, createTheme, XStack, YStack, ZStack, SizableText, Paragraph, Theme, useTheme, useMedia, $sm, $md, $lg, enterStyle, exitStyle, hoverStyle, pressStyle, transition prop, Sheet, Dialog, Adapt, GetProps, TamaguiProvider, @tamagui/core, @tamagui/config</p>\n<p><strong>When to use:</strong></p>\n<ul>\n<li>Building universal React Native + web UIs that share components across platforms</li>\n<li>Creating design-system-driven components with typed token scales and theme variants</li>\n<li>Optimizing render performance via compiler flattening (styled components to native divs/Views)</li>\n<li>Implementing responsive layouts with media query style props (<code>$sm</code>, <code>$gtMd</code>)</li>\n<li>Adding enter/exit/hover/press animations with swappable animation drivers</li>\n<li>Building adaptive overlays (Dialog on desktop, Sheet on mobile) with <code>Adapt</code></li>\n</ul>\n<p><strong>When NOT to use:</strong></p>\n<ul>\n<li>Web-only projects where a web-native styling solution is simpler</li>\n<li>Apps needing pixel-perfect custom native UI beyond what React Native Views provide</li>\n<li>Performance-critical animations that need direct native driver control beyond Tamagui's animation abstraction</li>\n</ul>\n<p><strong>Key patterns covered:</strong></p>\n<ul>\n<li><code>styled()</code> with typed variants (spread, boolean, functional) and <code>GetProps</code> type extraction</li>\n<li>Token system (<code>createTokens</code>, <code>$</code>-prefix references, category-to-property mapping)</li>\n<li>Theme hierarchy (base, sub-themes, component themes, <code>useTheme</code>, dark/light switching)</li>\n<li>Optimizing compiler (flattening, CSS extraction, what prevents optimization)</li>\n<li>Responsive styles with media query props and <code>useMedia</code> hook</li>\n<li>Animation system with <code>transition</code> prop, <code>enterStyle</code>/<code>exitStyle</code>, and driver selection</li>\n<li>Sheet and Dialog with <code>Adapt</code> for responsive overlay behavior</li>\n</ul>\n<p><strong>Detailed Resources:</strong></p>\n<ul>\n<li><a href=\"examples/core.md\">examples/core.md</a> - styled(), variants, tokens, themes, compiler optimization</li>\n<li><a href=\"examples/responsive-animations.md\">examples/responsive-animations.md</a> - Media queries, useMedia, animation drivers, enter/exit styles</li>\n<li><a href=\"examples/overlays.md\">examples/overlays.md</a> - Sheet, Dialog, Adapt pattern</li>\n<li><a href=\"reference.md\">reference.md</a> - Decision frameworks, token-to-property mapping, migration notes</li>\n</ul>\n<hr>\n\n<hr>\n\n<hr>\n<p>&lt;decision_framework&gt;</p>\n<h2>Decision Framework</h2>\n<h3>When to Use styled() vs Inline Props</h3>\n<pre><code>Is this a reusable component with variants or a semantic name?\n├─ YES → styled() with name, variants, defaultVariants\n└─ NO → Is this one-off layout?\n    ├─ YES → Inline props on XStack/YStack (&lt;YStack padding=\"$4\"&gt;)\n    └─ NO → styled() if you want component themes or compiler naming\n</code></pre>\n<h3>Animation Driver Selection</h3>\n<pre><code>Platform target?\n├─ Web only → @tamagui/animations-css (smallest bundle, CSS transitions)\n├─ Native only → @tamagui/animations-reanimated (worklet-based, spring physics)\n├─ Universal → Configure per-platform in createTamagui\n│   ├─ Web: CSS or Motion driver\n│   └─ Native: Reanimated or React Native driver\n└─ Simple transitions?

Lift state above the Dialog if persistence is needed.</li>\n<li><strong>Spread variants (<code>...size</code>) only match top-level token categories</strong> -- custom nested token groups require functional variants instead.</li>\n<li><strong><code>elevation</code> prop</strong> generates both shadow props (iOS) and elevation (Android) on native, but translates to <code>box-shadow</code> on web. Differences in shadow appearance across platforms are expected.</li>\n<li><strong>Config v5 changed flex defaults:</strong> With <code>styleCompat: 'react-native'</code>, <code>flex</code> uses <code>flexBasis: 0</code> (not <code>auto</code>).
