Expert guidance on iOS accessibility best practices, patterns, and implementation. Use when developers mention: (1) iOS accessibility, VoiceOver, Dynamic Type, or assistive technologies, (2) accessibility labels, traits, hints, or values, (3) automated accessibility testing, auditing, or manual testing, (4) Switch Control, Voice Control, or Full Keyboard Access, (5) inclusive design or accessibility culture, (6) making apps work for users with disabilities.
Apply platform accessibility best practices to SwiftUI, UIKit, and AppKit code. Essential companion to any SwiftUI, UIKit, or AppKit skill — always use together. Use whenever writing, editing, or reviewing ANY SwiftUI views, UIKit view controllers, AppKit views/window controllers, or platform UI — even when the user doesn't mention accessibility. Also use when the user mentions VoiceOver, Voice Control, Dynamic Type, Reduce Motion, screen reader, a11y, WCAG, accessibility audit, Nutrition Labels, accessibilityLabel, UIAccessibility, NSAccessibility, assistive technologies, or Switch Control. Not for server-side Swift, non-UI packages, or CLI tools.
Use when code signing fails during build, archive, or upload — certificate not found, provisioning profile mismatch, errSecInternalComponent in CI, ITMS-90035 invalid signature, ambiguous identity, entitlement mismatch. Covers certificate, profile, keychain, entitlement, and archive signing diagnostics.
Initialise a project's App Store Connect context using the `asc init` command. Use this skill when: (1) Saving app context to a project directory: "asc init", "pin my app ID", "set up project context" (2) Auto-detecting the app from an Xcode project: user says "run asc init in my project folder" (3) Searching by app name: "asc init --name 'My App'" (4) Explaining what .asc/project.json is used for (5) Reading saved project context to avoid running asc apps list every session
This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference. Provides SF Symbols usage, rendering modes (monochrome, hierarchical, multicolor, palette), symbol effects, and variable values.
Use this skill when working with Sequencer, LevelSequence, cutscene, cinematic, camera, movie scene, sequencer event, or Movie Render Queue in Unreal Engine. See references/sequencer-patterns.md for dialogue cutscene, in-game camera, and scripted event patterns. For animation playback, see ue-animation-system.
Guides the agent through upgrading a Capacitor plugin to a newer major version. Supports upgrades from Capacitor 4 through 8, including multi-version jumps. Covers automated upgrade via official migration tools, Android SDK targets, Gradle configuration, Java/Kotlin versions, iOS deployment targets, and manual step-by-step fallback for each version. Do not use for app project upgrade or non-Capacitor plugin frameworks.
Flutter state management patterns — decision tree for setState, Provider, Riverpod, and BLoC with concrete examples and testing strategies
Use when SecItem calls fail — errSecDuplicateItem from unexpected uniqueness, errSecItemNotFound despite item existing, errSecInteractionNotAllowed in background, keychain items disappearing after app update, access group entitlement errors, or Mac keychain shim issues. Covers systematic error diagnosis with decision trees.
Expert iOS development skill covering SwiftUI, UIKit, Core Data, App Store guidelines, and performance optimization. Use this skill when building, reviewing, or debugging iOS apps - views, navigation, data persistence, animations, or submission preparation. Triggers on SwiftUI layout and state management, UIKit view controller lifecycle, Core Data model design and migrations, App Store Review Guidelines compliance, memory and rendering performance profiling, and Swift concurrency patterns for iOS.
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.
Expert in cross-platform mobile development (React Native/Flutter), bridging native performance with shared business logic.
