SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps you avoid production-grade gRPC pitfalls like ambiguous errors, missing deadlines, poor proto organization, and unsafe shutdown behavior that lead to brittle clients, slow outages, and hard-to-debug failures.

Core Features & Use Cases

  • Correct proto design & organization: Use domain-based, versioned directories and Request/Response wrapper messages to support backward-compatible evolution.
  • Server operability patterns: Register gRPC health checks, use interceptors for cross-cutting concerns, and perform graceful shutdown with a timeout fallback.
  • Robust client behavior & reliability: Reuse connections, set per-RPC deadlines, configure Kubernetes headless discovery with round-robin and retries, and handle errors with proper status codes.
  • Testing & security guidance: Use bufconn for in-memory tests and enable TLS/mTLS with reflection disabled in production.

Quick Start

Use the golang-grpc skill to review or implement your gRPC server and client for correct status codes, proto structure, interceptors, TLS, graceful shutdown, and bufconn-based tests.

FAQPage Schema
How do I handle errors correctly in a Go gRPC service?

Handle gRPC errors by returning specific status codes with optional rich error details. Using structured status codes instead of ambiguous errors prevents brittle clients and makes production failures significantly easier to debug.

What is the best way to organize protobuf definitions for evolving gRPC APIs?

Organize protobuf definitions using domain-based, versioned directories and Request/Response wrapper messages. This structure supports backward-compatible API evolution and prevents breaking existing clients when modifying gRPC schemas.

How do I test gRPC services in Go without hitting a real network port?

Use the bufconn package for in-memory gRPC testing without real network ports. This pattern allows you to validate server and client logic quickly by dialing an in-memory listener instead of allocating actual TCP connections.

Why should I set deadlines on gRPC client calls in Go?

Setting per-RPC deadlines on gRPC client calls prevents slow outages caused by hung requests. Deadlines ensure that clients do not wait indefinitely for unresponsive servers, maintaining overall system reliability.

How do I safely shutdown a gRPC server in Go?

Safely shutdown a gRPC server by calling GracefulStop with a timeout fallback. This ensures in-flight RPCs complete while preventing the server from hanging indefinitely if connections remain stubbornly open.

Does this gRPC guidance include setting up mTLS and interceptors?

Yes, the guidance covers configuring interceptors for cross-cutting logic and enabling TLS/mTLS with reflection disabled in production. Interceptors handle concerns like logging or auth uniformly across all gRPC calls.
