Generate iOS app icons as PNG imagesets for Xcode asset catalogs from SF Symbols (5000+ Apple-native) or Iconify API (275k+ open source icons from 200+ collections). Use when generating icons, creating icon assets, adding icons to asset catalog, or searching for icons for iOS projects.
Use when writing or reviewing Jetpack Compose UI for TV, keyboard, desktop, accessibility focus, D-pad navigation, FocusRequester, focusProperties, key events, or initial focus behavior.
Use when writing or reviewing Jetpack Compose layout APIs, modifier parameters, modifier chain construction, hardcoded root layout decisions, or layout wrappers around a single conditional.
SwiftData patterns — autosave, relationships, dangerous predicates, CloudKit constraints, indexing, class inheritance. Use when writing, reviewing, or debugging SwiftData code.
Guidance for configuring dependency injection in .NET MAUI apps — service registration in MauiProgram.cs, lifetime selection (Singleton / Transient / Scoped), constructor injection, Shell navigation auto-resolution, platform-specific registrations, and testability patterns. USE FOR: "dependency injection", "DI setup", "AddSingleton", "AddTransient", "AddScoped", "service registration", "constructor injection", "IServiceProvider", "MauiProgram DI", "register services", "BindingContext injection". DO NOT USE FOR: data binding (use maui-data-binding), Shell route configuration (use maui-shell-navigation), unit-test mocking frameworks (use standard xUnit and NSubstitute patterns).
Guidance for implementing CollectionView in .NET MAUI apps — data display, layouts (list & grid), selection, grouping, scrolling, empty views, templates, incremental loading, swipe actions, and pull-to-refresh. USE FOR: "CollectionView", "list view", "grid layout", "data template", "item template", "grouping", "pull to refresh", "incremental loading", "swipe actions", "empty view", "selection mode", "scroll to item", displaying scrollable data, replacing ListView. DO NOT USE FOR: simple static layouts without scrollable data (use Grid or StackLayout), map pin lists (use Microsoft.Maui.Controls.Maps), table-based data entry forms, or non-MAUI list controls.
Tie RevenueCat identity to your app's auth system. Use when the user asks to log in to RevenueCat, sync a user with RevenueCat, switch RevenueCat user on login, log out of RevenueCat, move a user from anonymous to identified, set appUserID, or handle account switching on iOS, Android, Kotlin Multiplatform, Flutter, or React Native.
Fast synchronous key-value storage for React Native via react-native-mmkv (Nitro-backed). Covers creating and configuring MMKV instances, reading/writing all value types (string, number, boolean, buffer), React hooks for reactive UI, value-change listeners, encryption, AsyncStorage migration, and state-management integrations (zustand, redux-persist, jotai, react-query). Also covers storage limits, multi-process mode, and the V4 upgrade from the class-based API.
Fast native networking primitives for React Native built on Nitro Modules — react-native-nitro-fetch, react-native-nitro-websockets, and react-native-nitro-text-decoder. Covers the fetch API, global replacement, prefetching and cold-start cache warming, the NitroWebSocket class and pre-warming, migrating from React Native's built-in WebSocket, the in-process NetworkInspector, native Perfetto / Instruments tracing, the native TextDecoder, and plugging nitro-fetch into axios via a custom adapter.
Wire Firebase Auth (email/password, Google, Apple) and Cloud Firestore into an Ionic Capacitor app. Trigger when adding Firebase Auth, Firestore, social sign-in via Firebase, or backend persistence using Google's Firebase platform.
Guide for migrating an existing web app, PWA, or SPA into a store-ready Capacitor iOS and Android app. Use this skill when users want to wrap or convert a web app into a mobile app, avoid thin WebView app store rejection, add native-feeling UX, handle permissions, offline behavior, account deletion, billing, testing, and Capgo live updates.
Use FlowR APIs correctly across Dart and Flutter projects. Use when writing or reviewing flowr_dart FlowR/FlowB code, flowr FrViewModel/FrBlocViewModel widgets, FrProvider setup, FrUnion state, stream helpers, or migration after FlowR breaking changes, even when the project has its own file layout.
