Full Sentry SDK setup for Apple platforms (iOS, macOS, tvOS, watchOS, visionOS). Use when asked to "add Sentry to iOS", "add Sentry to Swift", "install sentry-cocoa", or configure error monitoring, tracing, profiling, session replay, or logging for Apple applications. Supports SwiftUI and UIKit.
Index of Apple developer documentation for iOS, macOS, and related frameworks. Use when looking up what APIs exist in a framework, browsing available documentation, or deciding what docs to fetch. Covers SwiftUI, UIKit, XCTest, HealthKit, Combine, SwiftData, and more.
Use iOS/Swift code as the source of truth and implement the equivalent feature in Android/Kotlin. Understands the feature behavior, data structures, and logic from iOS, then creates idiomatic Android code that matches the target codebase's existing patterns. Use when porting features from iOS to Android or ensuring platform consistency.
REQUIRED: After creating ANY .swift, .m, .mm, .c, .cpp, or .h file in a directory containing a .xcodeproj, you MUST run add_to_xcode.rb to register it with the project. Without this step, the file will NOT appear in Xcode and will NOT compile.
Brad Frost's Atomic Design for UI component hierarchy: atoms, molecules, organisms, templates. Activate when building user interfaces, creating design systems, organizing components, or structuring frontend code. Applies to any UI framework (React, Vue, SwiftUI, etc.).
Debug applications using the dbg CLI debugger. Supports Node.js (V8/CDP), Bun (WebKit/JSC), and native code via LLDB (DAP). Use when: (1) investigating runtime bugs by stepping through code, (2) inspecting variable values at specific execution points, (3) setting breakpoints and conditional breakpoints, (4) evaluating expressions in a paused context, (5) hot-patching code without restarting (JS/TS), (6) debugging test failures by attaching to a running process, (7) debugging C/C++/Rust/Swift with LLDB, (8) any task where understanding runtime behavior requires a debugger. Triggers: "debug this", "set a breakpoint", "step through", "inspect variables", "why is this value wrong", "trace execution", "attach debugger", "runtime error", "segfault", "core dump".
Audit a codebase for maintenance and modernization. Challenges scope, reviews architecture/quality/tests/performance/dependencies, files deferred work via bd. Language-specific addendums for iOS/Swift, Go, and Web/JS/CSS activate automatically based on what's in the repo. Supports monorepos with mixed stacks.
Production-grade mobile app development and architecture for iOS (Swift/SwiftUI/UIKit), Android (Kotlin/Jetpack Compose), and cross-platform (React Native, Flutter, Kotlin Multiplatform, WebView). Use for navigation, state, networking, offline storage, auth/passkeys, push, performance, testing, CI/CD, and App Store/Play release readiness.
Design and implement local push notification campaigns to boost user engagement in mobile apps. Use this skill whenever the user mentions local push notifications, in-app notifications, user engagement campaigns, retention messaging, re-engagement nudges, or wants to add scheduled notifications to their app. Also trigger when the user asks about notification timing strategies, onboarding notification flows, or workout/habit/goal reminder systems. Covers iOS (Swift/UNUserNotificationCenter), Android (Kotlin/WorkManager+NotificationManager), Flutter (flutter_local_notifications), and React Native (notifee/expo-notifications).
Adding stable accessibility identifiers for screenshot automation across all frameworks. Covers Flutter, SwiftUI, UIKit, Jetpack Compose, XML Android, and React Native. Naming conventions, common widget patterns, and verification strategies.
Design and implement integration architectures connecting financial systems — APIs, FIX protocol, ISO 20022, event-driven patterns, batch feeds, idempotency, and resilience. Use when building custodian integration pipelines, implementing FIX connectivity for order routing, designing ISO 20022 or SWIFT migration messaging, building batch file processing for custodian feeds or EOD reconciliation, implementing idempotency for transaction APIs, designing retry or circuit breaker patterns, mapping data between systems with different schemas, or troubleshooting integration failures causing recon breaks. Trigger on: FIX protocol, ISO 20022, custodian feed, batch processing, API design, idempotency, circuit breaker, dead letter queue, data mapping, integration architecture, SWIFT migration, mTLS, file feed, event-driven, message broker.
