You design gRPC services for correctness and operability — proper status codes, deadlines, interceptors, and graceful shutdown matter as much as the happy path.\n\n**Modes:**\n\n- **Build mode** — implementing a new gRPC server or client from scratch.\n- **Review mode** — auditing existing gRPC code for correctness, security, and operability issues.\n\n**Dependencies:**\n\n- protoc: `brew install protobuf`\n- protoc-gen-go: `go install google.golang.org/protobuf/cmd/protoc-gen-go@latest`\n- protoc-gen-go-grpc: `go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest`\n\n# Go gRPC Best Practices\n\nTreat gRPC as a pure transport layer — keep it separate from business logic. The official Go implementation is `google.golang.org/grpc`.\n\nThis skill is not exhaustive. Please refer to library documentation and code examples for more information. For Go package docs, symbols, versions, importers, and known vulnerabilities, → See `samber/cc-skills-golang@golang-pkg-go-dev` skill (`godig`) — prefer it over Context7 for Go package facts. To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See `samber/cc-skills-golang@golang-gopls` skill (`gopls`). Context7 remains a fallback for docs not indexed on pkg.go.dev.\n\n## Quick Reference\n\n| Concern | Package / Tool |\n| --- | --- |\n| Service definition | `protoc` or `buf` with `.proto` files |\n| Code generation | `protoc-gen-go`, `protoc-gen-go-grpc` |\n| Error handling | `google.golang.org/grpc/status` with `codes` |\n| Rich error details | `google.golang.org/genproto/googleapis/rpc/errdetails` |\n| Interceptors | `grpc.ChainUnaryInterceptor`, `grpc.ChainStreamInterceptor` |\n| Middleware ecosystem | `github.com/grpc-ecosystem/go-grpc-middleware` |\n| Testing | `google.golang.org/grpc/test/bufconn` |\n| TLS / mTLS | `google.golang.org/grpc/credentials` |\n| Health checks | `google.golang.org/grpc/health` |\n\n## Proto File Organization\n\nOrganize 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`.\n\n[Proto & code generation reference](references/protoc-reference.md)\n\n## Server Implementation\n\n- Implement health check service (`grpc_health_v1`) — Kubernetes probes need it to determine readiness\n- Use interceptors for cross-cutting concerns (logging, auth, recovery) — keeps business logic clean\n- Use `GracefulStop()` with a timeout fallback to `Stop()` — drains in-flight RPCs while preventing hangs\n- Disable reflection in production — it exposes your full API surface\n\n```go\nsrv := grpc.NewServer(\n    grpc.ChainUnaryInterceptor(loggingInterceptor, recoveryInterceptor),\n)\npb.RegisterUserServiceServer(srv, svc)\nhealthpb.RegisterHealthServer(srv, health.NewServer())\n\ngo srv.Serve(lis)\n\n// On shutdown signal:\nstopped := make(chan struct{})\ngo func() { srv.GracefulStop(); close(stopped) }()\nselect {\ncase <-stopped:\ncase <-time.After(15 * time.Second):\n    srv.Stop()\n}\n```\n\n### Interceptor Pattern\n\n```go\nfunc loggingInterceptor(ctx context.Context, req any, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (any, error) {\n    start := time.Now()\n    resp, err := handler(ctx, req)\n    log.Printf(\"method=%s duration=%s code=%s\", info.FullMethod, time.Since(start), status.Code(err))\n    return resp, err\n}\n```\n\n## Client Implementation\n\n- Reuse connections — gRPC multiplexes RPCs on a single HTTP/2 connection; one-per-request wastes TCP/TLS handshakes\n- Set deadlines on every call (`context.WithTimeout`) — without one, a slow upstream hangs goroutines indefinitely\n- Use `round_robin` with headless Kubernetes services via `dns:///` scheme\n- Pass metadata (auth tokens, trace IDs) via `metadata.NewOutgoingContext`\n\n```go\nconn, err := grpc.NewClient(\"dns:///user-service:50051\",\n    grpc.WithTransportCredentials(creds),\n    grpc.WithDefaultServiceConfig(`{\n        \"loadBalancingPolicy\": \"round_robin\",\n        \"methodConfig\": [{\n            \"name\": [{\"service\": \"\"}],\n            \"timeout\": \"5s\",\n            \"retryPolicy\": {\n                \"maxAttempts\": 3,\n                \"initialBackoff\": \"0.1s\",\n                \"maxBackoff\": \"1s\",\n                \"backoffMultiplier\": 2,\n                \"retryableStatusCodes\": [\"UNAVAILABLE\"]\n            }\n        }]\n    }`),\n)\nclient := pb.NewUserServiceClient(conn)\n```\n\n## Error Handling\n\nAlways return gRPC errors using `status.Error` with a specific code — a raw `error` becomes `codes.Unknown`, telling the client nothing actionable. Clients use codes to decide retry vs fail-fast vs degrade.\n\n| Code                 | When to Use                                 |\n| -------------------- | ------------------------------------------- |\n| `InvalidArgument`    | Malformed input (missing field, bad format) |\n| `NotFound`           | Entity does not exist                       |\n| `AlreadyExists`      | Create failed, entity exists                |\n| `PermissionDenied`   | Caller lacks permission                     |\n| `Unauthenticated`    | Missing or invalid token                    |\n| `FailedPrecondition` | System not in required state                |\n| `ResourceExhausted`  | Rate limit or quota exceeded                |\n| `Unavailable`        | Transient issue, safe to retry              |\n| `Internal`           | Unexpected bug                              |\n| `DeadlineExceeded`   | Timeout                                     |\n\n```go\n// ✗ Bad — caller gets codes.Unknown, can't decide whether to retry\nreturn nil, fmt.Errorf(\"user not found\")\n\n// ✓ Good — specific code lets clients act appropriately\nif errors.Is(err, ErrNotFound) {\n    return nil, status.Errorf(codes.NotFound, \"user %q not found\", req.UserId)\n}\nreturn nil, status.Errorf(codes.Internal, \"lookup failed: %v\", err)\n```\n\nFor field-level validation errors, attach `errdetails.BadRequest` via `status.WithDetails`.\n\n## Streaming\n\n| Pattern | Use Case |\n| --- | --- |\n| Server streaming | Server sends a sequence (log tailing, result sets) |\n| Client streaming | Client sends a sequence, server responds once (file upload, batch) |\n| Bidirectional | Both send independently (chat, real-time sync) |\n\nPrefer streaming over large single messages — avoids per-message size limits and lowers memory pressure.\n\n```go\nfunc (s *server) ListUsers(req *pb.ListUsersRequest, stream pb.UserService_ListUsersServer) error {\n    for _, u := range users {\n        if err := stream.Send(u); err != nil {\n            return err\n        }\n    }\n    return nil\n}\n```\n\n## Testing\n\nUse `bufconn` for in-memory connections that exercise the full gRPC stack (serialization, interceptors, metadata) without network overhead. Always test that error scenarios return the expected gRPC status codes.\n\n[Testing patterns and examples](references/testing.md)\n\n## Security\n\n- TLS MUST be enabled in production — credentials travel in metadata\n- For service-to-service auth, use mTLS or delegate to a service mesh (Istio, Linkerd)\n- For user auth, implement `credentials.PerRPCCredentials` and validate tokens in an auth interceptor\n- Reflection SHOULD be disabled in production to prevent API discovery\n\n## Performance\n\n| Setting | Purpose | Typical Value |\n| --- | --- | --- |\n| `keepalive.ServerParameters.Time` | Ping interval for idle connections | 30s |\n| `keepalive.ServerParameters.Timeout` | Ping ack timeout | 10s |\n| `grpc.MaxRecvMsgSize` | Override 4 MB default for large payloads | 16 MB |\n| Connection pooling | Multiple conns for high-load streaming | 4 connections |\n\nMost services do not need connection pooling — profile before adding complexity.\n\n## Common Mistakes\n\n| Mistake | Fix |\n| --- | --- |\n| Returning raw `error` | Becomes `codes.Unknown` — client can't decide whether to retry. Use `status.Errorf` with a specific code |\n| No deadline on client calls | Slow upstream hangs indefinitely. Always `context.WithTimeout` |\n| New connection per request | Wastes TCP/TLS handshakes. Create once, reuse — HTTP/2 multiplexes RPCs |\n| Reflection enabled in production | Lets attackers enumerate every method. Enable only in dev/staging |\n| `codes.Internal` for all errors | Wrong codes break client retry logic. `Unavailable` triggers retry; `InvalidArgument` does not |\n| Bare types as RPC arguments | Can't add fields to `string`. Wrapper messages allow backwards-compatible evolution |\n| Missing health check service | Kubernetes can't determine readiness, kills pods during deployments |\n| Ignoring context cancellation | Long operations continue after caller gave up. Check `ctx.Err()` |\n\n## Cross-References\n\n- → See `samber/cc-skills-golang@golang-context` skill for deadline and cancellation patterns\n- → See `samber/cc-skills-golang@golang-error-handling` skill for gRPC error to Go error mapping\n- → See `samber/cc-skills-golang@golang-observability` skill for gRPC interceptors (logging, tracing, metrics)\n- → See `samber/cc-skills-golang@golang-testing` skill for gRPC testing with bufconn\n","tagline":"Provides gRPC usage guidelines, protobuf organization, and production-ready patterns for Golang microservices.
