Migrate a React Native project from NativeWind to Uniwind. Use when the user wants to replace NativeWind with Uniwind, upgrade from NativeWind, switch to Uniwind, or mentions NativeWind-to-Uniwind migration. Handles package removal, config migration, Tailwind 4 upgrade, cssInterop removal, theme conversion, and all breaking changes.
Uniwind — Tailwind CSS v4 styling for React Native. Use when adding, building, or debugging components in a React Native project that uses Uniwind classNames. Covers setup, Metro config, global.css, theming, className props, accent-* color props, platform/data/state/responsive variants, CSS variables, custom utilities, withUniwind for third-party components, cn/tailwind-merge, tailwind-variants, safe area utilities, gradients, fonts, React Navigation, UI kits, diagnostics, troubleshooting, and Uniwind Pro features. Does not cover NativeWind migration.
Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.
Use Tailwind CSS to style React Native components across web and native
End-to-end testing patterns with Playwright for full-stack Python/React applications. Use when writing E2E tests for complete user workflows (login, CRUD, navigation), critical path regression tests, or cross-browser validation. Covers test structure, page object model, selector strategy (data-testid > role > label), wait strategies, auth state reuse, test data management, and CI integration. Does NOT cover unit tests or component tests (use pytest-patterns or react-testing-patterns).
Keep JavaScript/TypeScript dependencies fresh with safety rails and monorepo support.

Expo provides tooling and services for React Native: app config and Prebuild (Continuous Native Generation), Expo SDK packages, development builds, EAS Build (cloud builds and internal distribution), and EAS Update (over-the-air JS updates). Use development builds for production apps; Expo Go is a limited playground.
