Delegate to a senior mobile developer for building, optimizing, securing, and deploying React Native, Flutter, native iOS (Swift/SwiftUI), and Android (Kotlin/Jetpack Compose) apps. Handle performance tuning to 60fps, offline-first sync with local DBs, security hardening, and app store compliance with automated tooling.
npx claudepluginhub rnavarych/alpha-engineer --plugin role-mobileExpert guidance on Android native development — Kotlin idioms, Jetpack Compose UI, Room database, Hilt dependency injection, Coroutines and Flow for async work, WorkManager for background tasks, Gradle build configuration (KTS), Material Design 3 theming, and Navigation Compose. Use when building or optimizing native Android applications.
Expert guidance on mobile app deployment — App Store Connect and Google Play Console configuration, code signing and provisioning profiles, Fastlane automation, app review guidelines compliance, phased rollout strategies, and crash reporting integration (Crashlytics, Sentry). Use when preparing, submitting, or managing mobile app releases.
Expert guidance on Flutter 3.27+ (Impeller default on all platforms, Material 3, WASM web, DevTools, Flame), Dart 3.3+ (records, patterns, sealed classes, extension types, macros), state management (Riverpod 2 with codegen, BLoC/Cubit 9.x, Signals), navigation (GoRouter 14+, auto_route), networking (Dio, retrofit, Ferry/Artemis GraphQL), local storage (Drift, ObjectBox, Isar, Hive CE, Realm), testing (widget_test, golden tests, Patrol 3.x, alchemist, mocktail, bloc_test), on-device AI (firebase_ai, google_generative_ai, MediaPipe Tasks), Flutter for Web (WASM default)/Desktop/Embedded, Mason, very_good_cli, flutter_gen, custom_lint, Flutter Hooks, freezed. Use when building or optimizing Flutter apps.
Expert guidance on iOS native development — Swift and SwiftUI best practices, UIKit interop, Core Data and SwiftData persistence, Combine reactive framework, structured concurrency (async/await, actors), App Clips, WidgetKit, Xcode project configuration, and Swift Package Manager. Use when building or optimizing native iOS applications.
Expert guidance on mobile performance optimization — achieving 60fps rendering, memory management (leak detection, large image handling), battery optimization, startup time reduction (cold/warm/hot), image loading strategies (Glide, SDWebImage, cached_network_image), and profiling tools (Instruments, Android Profiler, Flipper). Use when diagnosing or improving mobile app performance.

Use this agent when developing native iOS or Android applications, implementing React Native features, or optimizing mobile performance. This agent specializes in creating smooth, native-feeling mobile experiences. Examples:\n\n<example>\nContext: Building a new mobile app\nuser: "Create a TikTok-style video feed for our app"\nassistant: "I'll build a performant video feed with smooth scrolling. Let me use the mobile-app-builder agent to implement native performance optimizations."\n<commentary>\nVideo feeds require careful mobile optimization for smooth scrolling and memory management.\n</commentary>\n</example>\n\n<example>\nContext: Implementing mobile-specific features\nuser: "Add push notifications and biometric authentication"\nassistant: "I'll implement native push notifications and Face ID/fingerprint auth. Let me use the mobile-app-builder agent to ensure proper platform integration."\n<commentary>\nNative features require platform-specific implementation and proper permissions handling.\n</commentary>\n</example>\n\n<example>\nContext: Cross-platform development\nuser: "We need this feature on both iOS and Android"\nassistant: "I'll implement it using React Native for code reuse. Let me use the mobile-app-builder agent to ensure native performance on both platforms."\n<commentary>\nCross-platform development requires balancing code reuse with platform-specific optimizations.\n</commentary>\n</example>

React Native mobile development with platform-specific optimizations
Use this agent when you need expert assistance with Flutter mobile development tasks, including code analysis, widget creation, debugging, performance optimization, or architectural decisions. Examples: <example>Context: User is working on a Flutter app and faces issues with navigation. user: 'My Navigator.push isn't updating the UI correctly when moving to a new screen' assistant: 'Let me use the flutter-dev agent to analyze your navigation setup and provide a solution' <commentary>Since this is a Flutter-specific navigation issue, use the flutter-dev agent to provide expert guidance on Navigator problems.</commentary></example> <example>Context: User wants to create a custom widget that aligns with their app's design system. user: 'I need to create a custom button widget that matches our app's design system' assistant: 'I'll use the flutter-dev agent to create a button widget that aligns with your existing codebase structure and design patterns' <commentary>The user needs a Flutter widget that follows existing patterns, so use the flutter-dev agent.</commentary></example>
