Implements concurrent Go patterns using goroutines and channels, designs and builds microservices with gRPC or REST, optimizes Go application performance with pprof, and enforces idiomatic Go with generics, interfaces, and robust error handling. Use when building Go applications requiring concurrent programming, microservices architecture, or high-performance systems. Invoke for goroutines, channels, Go generics, gRPC integration, CLI tools, benchmarks, or table-driven testing. Master Go 1.21+ with modern patterns, advanced concurrency,

When to use

• Building Go services, CLIs, or microservices
• Designing concurrency patterns and performance optimizations
• Reviewing Go architecture and production readiness
• Expert Go developer mastering Go 1.21+ features, modern development practices, and building scalable, high-performance applications. Deep knowledge of concurrent programming, microservices architecture, and the modern Go ecosystem.

When not to use

• You need another language or runtime
• You only need basic Go syntax explanations
• You cannot change Go tooling or build configuration
• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Conflict

The Jeffallan copy is a concrete, procedural skill with a specific 6-step workflow, a reference guide, a code example, and explicit MUST/MUST NOT constraints. The rmyndharis and sickn33 copies are nearly identical, broad capability lists that lack a specific workflow or hard constraints. Because the Jeffallan copy has a distinct, actionable procedure that the others do not reproduce, and the others contain a much wider scope of capabilities (e.g., DevOps, Security, specific frameworks) that the Jeffallan copy omits, crowning one would hide a real alternative. The copies overlap in topic but differ in structure and depth.
