Use this skill when working with Unity game engine - C# scripting, Entity Component System (ECS/DOTS), physics simulation, shader programming (ShaderLab, HLSL, Shader Graph), and UI Toolkit. Triggers on gameplay programming, MonoBehaviour lifecycle, component architecture, rigidbody physics, raycasting, collision handling, custom shader authoring, material configuration, USS styling, UXML layout, and performance optimization for real-time applications. Acts as a senior Unity engineer advisor for game developers building production-quality games and interactive apps.
Use this skill when building Android applications with Kotlin. Triggers on Jetpack Compose UI, Room database, Kotlin coroutines, Play Store publishing, MVVM/MVI architecture, ViewModel, StateFlow, Hilt dependency injection, Navigation Compose, Material 3, APK/AAB builds, ProGuard, and Android app lifecycle management. Covers modern Android development with declarative UI, reactive state, structured concurrency, and production release workflows.
Walk through the full process of building a digital health app — from defining the need through planning to implementation.
Use when working with ANY calendar event, reminder, EventKit permission, or EventKitUI controller. Covers access tiers (no-access, write-only, full), permission migration from pre-iOS 17, store lifecycle, reminder patterns, EventKitUI controller selection, Siri Event Suggestions, virtual conference extensions.
Advanced Compose Multiplatform UI patterns for shared composables. Use when working with visual UI components, state management patterns (remember, derivedStateOf, produceState), recomposition optimization (@Stable/@Immutable visual usage), Material3 theming, custom ImageVector icons, or determining whether to share UI in commonMain vs keep platform-specific. Delegates navigation to android-expert/desktop-expert. Complements kotlin-expert (handles Kotlin language aspects of state/annotations).
Use when building, fixing, or improving ANY iOS UI including SwiftUI, UIKit, layout, navigation, animations, design guidelines. Covers view updates, layout bugs, navigation issues, performance, architecture, Apple design compliance.
Use when needing thread-safe primitives for performance-critical code. Covers Mutex (iOS 18+), OSAllocatedUnfairLock (iOS 16+), Atomic types, when to use locks vs actors, deadlock prevention with Swift Concurrency.
React Native Elements UI component library best practices for performance, theming, and proper component usage. Use when building React Native apps with RNE, configuring themes, optimizing lists with ListItem, or reviewing RNE component code.
Generate React Native Reanimated animation code for React Native apps. Use when user asks to create, implement, or add animations in React Native — including transitions, gestures, scroll-linked effects, layout animations, layout transitions, entering/exiting animations, CSS animations, CSS transitions, shared element transitions, color animations, parallax, fade, slide, scale, spring, timing, decay, keyframes, worklets, accordion, bottom sheet, flip card, collapsing header, or any motion effect using react-native-reanimated. Also use for integrating react-native-gesture-handler with Reanimated, understanding worklets, animating between screens, testing animations with Jest, or checking which properties are animatable.
HarmonyOS ArkTS application development with ArkUI declarative UI framework. Use when building HarmonyOS/OpenHarmony apps, creating ArkUI components, implementing state management with decorators (@State, @Prop, @Link), migrating from TypeScript to ArkTS, or working with HarmonyOS-specific APIs (router, http, preferences). Covers component lifecycle, layout patterns, and ArkTS language constraints.
Use when implementing gesture composition (simultaneous, sequenced, exclusive), adaptive layouts (ViewThatFits, AnyLayout, size classes), or choosing architecture patterns (MVVM vs TCA vs vanilla, State-as-Bridge). Covers advanced SwiftUI patterns beyond basic views.
