To implement a worker pool in Go, use bounded goroutines with channels for task distribution and context cancellation for safe shutdown. This Skill applies idiomatic Go patterns for correct goroutine lifecycle management and request-scoped processing.

A fan-out/fan-in pipeline in Go distributes tasks across multiple goroutines and aggregates results through channels. This Skill guides you to build concurrent pipelines with explicit error wrapping and safe shutdown behavior.

Table-driven tests in Go use struct slices to define input and expected output cases, validated with the `-race` flag to detect concurrency issues. This Skill enforces race-detector validation and robust error handling for production code.

Yes, this approach works for gRPC and REST integrations by building microservices with small, composable interfaces and explicit contracts. This Skill targets production-grade service design using idiomatic Go 1.21+ patterns.

Profiling a Go application with pprof identifies hot paths in concurrent code for performance tuning and benchmarking. This Skill applies profiling-driven optimizations alongside bounded worker pools and context-aware pipelines.

Goroutine leaks during shutdown often occur due to missing context propagation or unbounded goroutine creation. This Skill prevents leaks by applying correct goroutine lifecycle management, context cancellation, and explicit error wrapping.
