What problem does it solve? Building React Native apps with AI assistance often produces hallucinated native code, inconsistent styling, and weak typing. This Skill enforces a strict Expo Managed Workflow with opinionated conventions so generated mobile code stays consistent, typed, and maintainable. ## Core Features & Use Cases - Expo Managed Workflow Enforcement: Bans direct modification of ios/ and android/ native folders, requiring Expo Config plugins instead to prevent hallucinated native configuration. - Opinionated Stack: Mandates Expo Router file-based routing, NativeWind utility styling, Zustand state management, and strict TypeScript across all components and API responses. - Governance Rules: Provides universal DateTime handling (epoch ms normalization, locale-aware formatting) and Jest plus React Native Testing Library testing strategies. - Use Case: When starting a new cross-platform mobile app, apply this Skill so the AI scaffolds an app/ directory with typed routes, NativeWind-styled components, and Zustand stores following a single consistent architecture. ## Quick Start Scaffold a new Expo app with Expo Router, NativeWind, Zustand, and strict TypeScript following this skill's project structure and conventions.
