golang-concurrency — Skills

What it does

Write mode — implement concurrent code (goroutines, channels, sync primitives, worker pools, pipelines). Follow the sequential instructions below.

[ ] How will it exit? — context cancellation, channel close, or explicit signal

[ ] Can I signal it to stop? — pass context.Context or done channel

[ ] Can I wait for it? — sync.WaitGroup or errgroup

[ ] Who owns the channels? — creator/sender owns and closes

[ ] Should this be synchronous instead? — don't add concurrency without measured need

-> See samber/cc-skills-golang@golang-performance skill for false sharing, cache-line padding, sync.Pool hot-path patterns

golang-concurrency FAQ

What does the golang-concurrency skill do?

Golang concurrency patterns. Use when writing or reviewing concurrent Go code involving goroutines, channels, select, locks, sync primitives, errgroup, singleflight, worker pools, or fan-out/fan-in pipelines. Also triggers when you detect goroutine leaks, race conditions, channel ownership issues, or need to choose between channels and mutexes. Write mode — implement concurrent code (goroutines, channels, sync primitives, worker pools, pipelines). Follow the sequential instructions below. [ ] How will it exit? — context cancellation, channel close, or explicit signal
