Provides a structured workflow for migrating an Android XML View to Jetpack Compose. This skill details the step-by-step process, from planning and dependency setup, to theming and layout migration, validation and XML cleanup. Use this skill when you need to migrate an XML View to Jetpack Compose in an Android project. It solves the problem of converting the UI of a legacy XML View into modern, declarative Compose components while maintaining interoperability.
Use when app feels slow, memory grows, battery drains, or diagnosing ANY performance issue. Covers memory leaks, profiling, Instruments workflows, retain cycles, performance optimization.
Use when building, fixing, or improving ANY SwiftUI UI — views, navigation, layout, animations, performance, architecture, gestures, debugging, iOS 26 features.
Use when bridging UIKit and SwiftUI, debugging Auto Layout constraints, working with Combine, TextKit, or UIKit animations.
Visual effects and material specialist - Masters Unity Shader Graph, HLSL, URP/HDRP rendering pipelines, and custom pass authoring for real-time visual effects
Use when writing or reviewing Kotlin Flow state and event APIs with StateFlow, MutableStateFlow.update, SharedFlow, Channel, stateIn, SharingStarted, .value, receiveAsFlow, one-shot events, or sentinel initial values.
Add an iOS App Clip target to an Expo app. Use when the user mentions App Clip, AASA, apple-app-site-association, appclips, smart app banner, or wants to ship a lightweight iOS Clip invoked from a URL alongside their parent app.
Airbnb-DLS-aligned design system engineering for Expo / React Native apps targeting both web and native iOS, built on Unistyles v3, Reanimated, Skia, and FlashList. Use whenever building, reviewing, or refactoring shared UI — design tokens, theming, variant-driven component APIs, typography, spacing, cross-platform web/iOS parity, native-feel performance, or complex surfaces like calendars and drawing canvases (examples use a clinic app). Covers token architecture, theming, component API contracts (variants over style props), web/iOS parity (Unistyles `_web` hover/focus/cursor, Platform splits, one shared theme), the Unistyles styling engine, and governance. Trigger even when the user does not say "design system" but is creating or changing reusable React Native components, tokens, theme code, or making a component behave natively on both web and iOS. Teaches how to BUILD the design system; pair with expo-react-native-coder for features and expo-ios-hig for iOS native-feel decisions.
Use when adding Auth0 login, logout, or session management to an Expo app. Integrates react-native-auth0 with the Expo Config Plugin for native iOS/Android builds — use even if the user says "add login to my Expo app" without mentioning the SDK. Do not use for bare React Native CLI projects.
Use when adding Auth0 login, logout, or biometric-protected credential storage to a Flutter mobile app (iOS or Android). Integrates auth0_flutter on the native platform — use even if the user says "add login to my Flutter app".
Use when upgrading an iOS or macOS app's Auth0.swift SDK from v2 to v3. Detects the current version, fetches the new SDK source to confirm API signatures, and applies only the breaking changes that affect real call sites — use even if the user says "update my Auth0 Swift SDK" or "migrate to Auth0.swift v3".
Implement, review, or improve SwiftUI features using the iOS 26+ Liquid Glass API. Use when asked to adopt Liquid Glass in new SwiftUI UI, refactor an existing feature to Liquid Glass, or review Liquid Glass usage for correctness, performance, and design alignment.
