Skill UI

This skill provides guidance for building and releasing iOS and Android applications using Expo Application Services (EAS). It covers workflows for Expo and React Native projects, as well as existing native apps. Users can learn how to configure build profiles, submit to App Store Connect and Google Play Store, manage versions, and automate CI/CD pipelines for app distribution.

EAS Simulator runs remote iOS or Android emulators on EAS infrastructure, enabling developers to test apps via CLI, AI agents, or browser preview. It unlocks testing environments where local simulators cannot run, such as Linux or cloud agents. Use this to verify app changes remotely on real device environments.

This skill enables integrating Expo and React Native into existing native iOS or Android applications. It covers brownfield scenarios, including embedding React Native via AAR/XCFramework or adding Expo to Kotlin/Swift projects. It supports both isolated and integrated approaches for native team collaboration.

This skill enables developers to build Expo development clients using EAS Build for testing native code changes on physical devices. It is recommended for real or production apps instead of Expo Go, supporting local modules, Apple targets, and third-party native modules. Users configure eas.json with developmentClient settings and use commands like eas build to create iOS or Android builds for TestFlight or local installation.

This guide covers creating and writing Expo native modules and views using the Expo Modules API. It supports Swift for iOS, Kotlin for Android, and TypeScript. Topics include module definition DSL, native views, shared objects, config plugins, lifecycle hooks, autolinking, and type system. Ideal for adding native functionality like camera or sensors to Expo apps.

Set up Tailwind CSS v4 in Expo with react-native-css and NativeWind v5 for universal styling across iOS, Android, and Web. Covers installation, Metro/PostCSS configuration, global CSS, and reusable component wrappers.

Build native iOS and Android UI components using React with the @expo/ui package. Supports universal cross-platform components and platform-specific SwiftUI or Jetpack Compose rendering. Ideal for Expo SDK 56+ projects needing high-performance native interfaces without writing separate native code.

This skill enables developers to build Android-native user interfaces within Expo applications using the @expo/ui/jetpack-compose package. It allows integration of Jetpack Compose views and modifiers, mirroring the Compose API for Material Design 3 components. Users must wrap Jetpack Compose trees in Host components and follow specific installation steps for Expo SDK 55. It supports scrollable lists via LazyColumn and icons via XML vector drawables, facilitating native Android UI patterns in cross-platform development.

Automatically creates professional client-ready proposals based on GEO audit data. Translates technical findings into business pain points, suggests service tiers, and includes ROI projections for SEO agencies targeting AI search visibility.

This comprehensive guide outlines the principles and technical implementation for creating highly accessible, high-contrast user interfaces. It ensures WCAG AAA compliance by specifying pure black/white color pairings, clear boundaries, and legible typography across web (CSS), iOS (SwiftUI), and Android (Flutter) platforms. Ideal for applications requiring maximum legibility and stark visual impact.

Analyzes Brazilian real estate auction markets to evaluate liquidity, typical discounts, and ROI. Provides exit strategies such as flipping, renovation, or rental income, alongside financial benchmarks like Selic and CDI.

This skill performs comprehensive risk analysis for real estate auctions. It calculates a 36-point risk score covering legal, financial, and operational aspects. It includes stress testing across four scenarios and calculates risk-weighted ROI. Designed for Brazilian property auctions, it helps identify safe investments using AI tools.
