Best practices for Jetpack Compose text fields in Android apps. Use when building forms or search inputs and you need guidance on IME padding, keyboard options, focus movement, and accessible input behavior.
Build, refactor, review, and debug native Apple-platform software in Swift. Use when working on `.swift` files, SwiftUI views, Observation-based state, `@Bindable` and binding flow, SwiftData-backed UI, scenes and windows, search/navigation structures, UIKit/AppKit interop, Liquid Glass adoption, macOS-native UX, or SwiftUI performance/accessibility. Trigger on requests to create or polish iOS, iPadOS, macOS, or visionOS features; clean up SwiftUI view structure; diagnose jank or invalidation storms; review app quality; or make a feature feel like a good Apple-platform citizen.
Remove the DebugBridge SPM package and all #if DEBUG wiring from an iOS app. Cleans up StateServer, DebugOverlay, accessor codegen output, and app-side hooks installed by /ios-qa. This is a convenience wrapper — the structural Release-build guard (Package.swift conditional + CI swift build -c release check) is the safety-critical path. Use when asked to "clean the iOS debug bridge", "remove DebugBridge", or "strip the gstack iOS instrumentation". (gstack) Voice triggers (speech-to-text aliases): "clean the iOS debug bridge", "remove DebugBridge", "strip the gstack iOS instrumentation".
GeoToolbox PlaceDescriptor patterns with MapKit integration for location representation, geocoding, and multi-service place identifiers. Use when working with place descriptors, geocoding, or cross-service location data.
AlarmKit integration for scheduling alarms and timers with custom UI, Live Activities, and snooze support. Use when implementing alarm or timer features in iOS 18+ apps.
Styled text display and rich text editing in SwiftUI using Text, AttributedString, and TextEditor with formatting controls. Use when implementing rich text editing or styled text display.
Unity shaders, materials, and rendering pipelines (URP/HDRP/Built-in). PROACTIVELY activate for: (1) writing shaders in Shader Graph, HLSL, or ShaderLab, (2) URP and HDRP shader authoring, (3) custom render pipeline work (SRP), (4) lighting setup (baked vs realtime, lightmaps, Global Illumination), (5) post-processing stacks, (6) reflection probes and light probes, (7) custom render features and full-screen passes, (8) shader stripping and variant management, (9) compute shaders, (10) ray tracing in HDRP. Provides: Shader Graph templates, HLSL snippets, URP/HDRP differences, lighting setup recipes, render-feature examples, and shader-variant guidance.
Debug logging, Debug menu, runtime pitfalls, typing-latency-sensitive paths, SwiftUI list snapshot boundaries, OS-version repros, and local visual iteration for cmux. Use when adding debug probes, diagnosing UI/runtime issues, touching terminal rendering, tab/sidebar list views, drag/drop UTTypes, or using the Debug menu.
Flutter Performance. Use when optimizing performance or profiling code.
General rules pertaining to Mobile UI development. Covers UI/UX best practices, state management, and navigation patterns.
Guide for theming .NET MAUI apps—light/dark mode support, AppThemeBinding, dynamic resources, ResourceDictionary theme switching, and system theme detection. USE FOR: "dark mode", "light mode", "theming", "AppThemeBinding", "theme switching", "ResourceDictionary theme", "dynamic resources", "system theme detection", "color scheme", "app theme". DO NOT USE FOR: localization or language switching (use maui-localization), accessibility visual adjustments (use maui-accessibility), or app icons (use maui-app-icons-splash).
Expert blueprint for FPS/TPS shooter games (Call of Duty, Counter-Strike, Apex Legends, Fortnite) covering weapon systems, recoil patterns, hitscan vs projectile, aim assist, multiplayer prediction, and gunplay feel. Use when building competitive shooters, battle royales, or tactical FPS games requiring responsive combat. Keywords hitscan, recoil pattern, aim assist, client prediction, weapon archetype, projectile physics, hit registration.
