Kotlin Coroutines Expert

What it does

This skill provides expert-level assistance with Kotlin coroutines. It can help debug complex asynchronous code, optimize performance bottlenecks related to concurrency, and generate idiomatic coroutine implementations for various tasks. The skill understands advanced coroutine concepts like channels, flows, and structured concurrency.

When to use it

• Debugging Asynchronous Code: You're encountering unexpected behavior or errors in your Kotlin coroutines-based application and need help identifying the root cause.
• Performance Optimization: Your coroutine code is slow or inefficient, and you want suggestions for improving its performance through better concurrency patterns.
• Implementing Complex Flows: You need to create a complex data pipeline using Kotlin flows but are unsure of the best approach.
• Understanding Structured Concurrency: You're trying to implement structured concurrency with CoroutineScope and supervisor/launch and require guidance on proper usage.

Key capabilities

• Debugging coroutine code
• Optimizing coroutine performance
• Generating Kotlin flow implementations
• Explaining structured concurrency concepts
• Understanding channels and actors

Example prompts

• "My coroutine is throwing a CancellationException. Can you help me debug it?"
• "How can I optimize this Kotlin flow to reduce latency?"
• "Can you show me an example of using supervisor to handle multiple tasks concurrently?"
• “Explain the difference between launch and async in coroutines.”

Tips & gotchas

• The skill assumes a working knowledge of Kotlin programming. A basic understanding of asynchronous programming concepts is also beneficial.
