How does this skill improve Android development?

It enforces the use of lifecycle-bound scopes like viewModelScope and lifecycleScope, which automatically clean up tasks to prevent memory leaks and crashes.

How are errors handled in these patterns?

The skill includes patterns for localized error handling within coroutines and the use of supervisorScope to prevent a single failure from cancelling independent sibling tasks.

What is the Coroutines Patterns skill?

It is a specialized capability for Claude Code that provides domain-specific guidance and implementation patterns for Kotlin Coroutines and Flow, focusing on structured concurrency.

Does it help with threading performance?

Yes, it guides the correct usage of Dispatchers (Main, IO, and Default) to ensure that UI operations remain smooth while heavy tasks run in the background.

Does this skill support reactive UI patterns?

Yes, it provides standard patterns for using StateFlow for UI state and SharedFlow for one-time events, integrated with lifecycle-aware collection.

Mobile Development

Implements structured concurrency and reactive flow patterns in Kotlin to manage asynchronous operations and UI state efficiently.

About

The Coroutines Patterns skill equips Claude with specialized knowledge for writing robust, lifecycle-aware Kotlin code. It focuses on structured concurrency to prevent memory leaks, strategic dispatcher management for optimized threading, and advanced Flow patterns for reactive UI state. This skill is essential for mobile developers working on Android applications, providing standardized implementations for ViewModel scopes, error handling with supervisorScope, and cooperative cancellation techniques that ensure apps remain responsive and crash-free during complex background tasks.

Key Features

Lifecycle-aware coroutine scope management (ViewModelScope, LifecycleScope)
Cooperative cancellation patterns to ensure resource efficiency
Robust error handling via try-catch and supervisorScope strategies
Reactive stream management using StateFlow and SharedFlow patterns
Optimized Dispatcher selection for UI, IO, and CPU-intensive tasks
1 GitHub stars

Use Cases

Handling complex asynchronous task chains with proper error propagation
Implementing reactive UI state updates using Flow and StateFlow
Managing background network calls and database queries in Android apps
