Comprehensive Swift development expert skill with extensive coverage of modern Swift patterns, concurrency models, and Apple ecosystem tools. Well-structured workflow with clear quality standards and integration capabilities.

A CLI tool for seeding and verifying HealthKit data in Expo apps during development. It lets developers batch-write realistic health metrics via NDJSON, query existing samples, and generate statistics for testing health-related app features without physical devices.

This skill provides a template for building CLI tools that connect to running Expo apps via WebSocket. It includes complete TypeScript code for both CLI client and React Native hook, with detailed protocol specifications for the DevTools plugin system. The architecture uses Bun runtime and Stricli framework for type-safe CLI development.

A collection of 21 Python/bash scripts for iOS simulator automation. It handles app testing, UI navigation via accessibility APIs, build automation, and device management. Outputs structured JSON for CI/CD integration and supports semantic element finding instead of pixel coordinates.

Provides concrete Flutter performance optimization techniques with specific code examples for build cost control, list rendering, animation efficiency, and anti-pattern avoidance. Includes practical debugging methods and references to official documentation.

This skill provides structured guidance for Swift concurrency across three workflows: building new async code, auditing existing code for issues, and refactoring legacy patterns. It includes decision trees, checklists, and concrete code examples for modern Swift 6+ patterns like actors, Sendable, and structured concurrency.

A specialized agent for mobile app development across iOS, Android, and cross-platform frameworks. It provides structured workflows for requirements analysis, implementation, and launch, with specific checklists for performance metrics like app size, startup time, and crash rates. Integrates with tools like Xcode, Android Studio, and Fastlane.

A Flutter/Dart development assistant focused on modern patterns (Dart 3.5+, Flutter 3.24+). It provides concrete code examples for Riverpod state management, go_router navigation, platform channels, and performance optimization. The skill includes testing frameworks and memory management guidance.

A gateway skill that auto-detects mobile development work and provides access to React Native skills. It triggers on iOS/Swift keywords and guides users to browse related skills via file system commands. Acts as an entry point to a curated mobile development knowledge base.

A macOS wrapper for scrcpy that displays Android device screens with an integrated console for live app logs. Provides a unified interface similar to iPhone screen capture, including window controls and keyboard shortcuts for common scrcpy operations.

This skill provides detailed guidance for building high-quality Expo native modules for iOS and Android. It covers API design patterns, view implementation, marshalling techniques, shared objects, and ecosystem integration with concrete code examples and best practices.

Provides concrete guidelines for writing and reviewing Swift code with a focus on Swift 6+ concurrency features, API design, and migration strategies. Includes specific code examples for async/await, actors, and MainActor usage, along with common pitfalls to avoid. Targets macOS 15.7+ and iOS 18+ development.
