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.
