Async Patterns

Comprehensive guidance on asynchronous programming and concurrency patterns across languages, covering async/await, channels, actors, structured concurrency, and strategies for avoiding common pitfalls like deadlocks and race conditions.

When to Use This Skill

Use this skill for:

• Implementing async/await in Python, JavaScript, Rust, or C#
• Choosing between concurrency models (threads, coroutines, actors, CSP)
• Designing producer-consumer, fan-out/fan-in, or pipeline architectures
• Debugging race conditions, deadlocks, or resource starvation
• Adding backpressure handling to streaming systems
• Writing tests for asynchronous code
• Implementing structured concurrency with task groups and cancellation
• Converting callback-based code to async/await
