Individual skill
cross-platform-design
Use when the user wants one codebase or one product design across web, iOS, Android, Windows, and Mac, asks for the same app on all platforms, asks to translate/port a UI between platforms, or names Compose Multiplatform, Tauri 2, Electron, React Native, Flutter, .NET MAUI, Avalonia, or Uno Platform. Builds cross-platform UI by preserving UX decisions, originality seed, desktop archetype, state coverage, tokens, and product job while translating each surface into the host platform's native idiom rather than pixel-cloning. SKIP when only one platform is targeted and no translation/cross-platform tradeoff is involved.

# cross-platform-design — translate idiom, not pixels
Goal: ship one codebase that respects each platform's HIG/Material/Fluent — not a Flutter app that looks like Flutter on every OS.
## What This Skill Can Do
- Choose cross-platform stacks and explain tradeoffs across Tauri, Electron, React Native, Flutter, Compose Multiplatform, Avalonia, Uno, and MAUI.
- Translate Apple, Android, Windows, and web patterns by idiom instead of copying pixels.
- Preserve UX briefs, state coverage, action hierarchy, tokens, desktop archetype, originality seed, layout sketch, and product metaphor across platforms.
- Define per-platform navigation, controls, typography, icons, motion, density, and accessibility adaptations.
- Warn when one shared UI will harm platform fit or when a single-platform implementation is the better choice.
## Step 0 — Preserve UX and UI decisions
