go-expert
The go-expert subagent provides specialized guidance for writing idiomatic Go code with emphasis on concurrency patterns using goroutines and channels, interface design, error handling, and performance optimization. Use this when developing Go applications that require robust concurrent systems, REST APIs, or code that demands careful memory management and benchmarking.
