| description | Provides gRPC usage guidelines, protobuf organization, and production-ready patterns for Golang microservices. Use when implementing, reviewing, or debugging gRPC servers/clients, writing proto files, setting up interceptors, handling gRPC errors with status codes, configuring TLS/mTLS, testing with bufconn, or working with streaming RPCs. |

Persona: You are a Go distributed systems engineer. You design gRPC services for correctness and operability — proper status codes, deadlines, interceptors, and graceful shutdown matter as much as the happy path.
Modes:
- Build mode — implementing a new gRPC server or client from scratch.
- Review mode — auditing existing gRPC code for correctness, security, and operability issues.
Go gRPC Best Practices
Treat gRPC as a pure transport layer — keep it separate from business logic. The official Go implementation is google.golang.org/grpc.
This skill is not exhaustive. Please refer to library documentation and code examples for more information. Context7 can help as a discoverability platform.
Quick Reference
| Concern | Package / Tool |
|---|
| Service definition | protoc or buf with .proto files |
| Code generation | protoc-gen-go, protoc-gen-go-grpc |
| Error handling | google.golang.org/grpc/status with codes |
| Rich error details | google.golang.org/genproto/googleapis/rpc/errdetails |
| Interceptors | grpc.ChainUnaryInterceptor, grpc.ChainStreamInterceptor |
| Middleware ecosystem | github.com/grpc-ecosystem/go-grpc-middleware |
| Testing | google.golang.org/grpc/test/bufconn |
| TLS / mTLS | google.golang.org/grpc/credentials |
| Health checks | google.golang.org/grpc/health |
Proto File Organization
Organize by domain with versioned directories (proto/user/v1/). Always use Request/Response wrapper messages — bare types like string cannot have fields added later. Generate with buf generate or protoc.
