This Skill helps you design, review, and fix concurrent Go code so goroutines stop cleanly, shared state is protected correctly, and cancellation works predictably.
Ask for a review of your Go concurrency code and have it checked for goroutine leaks, unsafe channel usage, and the correct synchronization primitive.

Prevent goroutine leaks by applying structured cancellation, ensuring every goroutine has a clear stop path, and verifying cleanup deterministically using goleak tests in your Go concurrency code.
The safest channel closing approach is sender-owned closing, where only the sending goroutine closes the channel, combined with context-aware select loops to prevent panics and unsafe channel misuse.
Choose mutexes for complex critical sections, and atomics for simple counter or flag updates, while also evaluating sync.Map, sync.Once, sync.Pool, and singleflight for specific Go concurrency patterns.
Implement first-error cancellation in Go worker pools by using errgroup workflows, which provide bounded concurrency and automatically cancel remaining goroutines when the first error occurs.
Test Go concurrency timing deterministically using synctest, which allows you to control and verify goroutine scheduling and timing behavior without relying on flaky sleep calls.
Channel sends hang when receivers are missing or cancellation fails; fix this by applying channel direction constraints, context-aware select loops, and ensuring senders own the channel lifecycle.
