go-concurrency-patterns

Quick Review

Excellent skill for Go concurrency patterns with comprehensive, production-ready code examples. The Description clearly communicates when to use this skill (worker pools, race condition debugging, concurrent applications). Task knowledge is strong with 7 detailed patterns covering worker pools, fan-out/fan-in, semaphores, graceful shutdown, error groups, concurrent maps, and select patterns. Structure is clear and logical with good categorization, though the single-file format becomes lengthy. Novelty is moderate-to-good: while goroutines and channels are fundamental Go concepts, the combined patterns (especially graceful shutdown, bounded concurrency, and sharded maps) provide substantial value that would require significant token expenditure for a CLI agent to reproduce correctly and safely.
