Can it help with context cancellation?

Yes, it includes specific patterns for using the context package to manage timeouts and cancel long-running goroutines safely across your application.

Does it support the errgroup package?

Yes, it offers implementation guidance on using golang.org/x/sync/errgroup for efficient error propagation and synchronization of groups of goroutines.

What concurrency patterns are included?

The skill covers a wide range of patterns including worker pools, pipelines, fan-out/fan-in, semaphores, and token-bucket rate limiting.

How does this skill help with race conditions?

It provides patterns for proper synchronization using Mutexes and RWMutexes, and guides you on using the Go race detector to identify and resolve data races.

Implements advanced Go concurrency patterns using goroutines, channels, and synchronization primitives to build high-performance parallel systems.

关于

This skill equips Claude with specialized knowledge of Go's concurrency model, enabling it to help you write thread-safe, efficient, and scalable Go code. It provides production-ready implementation patterns for worker pools, pipelines, and fan-out/fan-in architectures while offering deep insights into synchronization primitives like Mutexes and WaitGroups. Whether you are optimizing parallel processing, managing complex state, or debugging subtle race conditions, this skill ensures your concurrent Go applications are robust, leak-free, and performant.
