gRPC Protocol Skill
Expert skill for gRPC protocol implementation, service definition, and debugging across multiple languages.
Capabilities
- •Service Definition: Generate gRPC service definitions and Protocol Buffer schemas
- •Code Generation: Generate client and server stubs for multiple languages
- •Streaming Debugging: Debug unary, client-streaming, server-streaming, and bidirectional streaming
- •gRPC-Web Compatibility: Analyze and configure gRPC-web for browser clients
- •Load Balancing: Configure gRPC-specific load balancing strategies
- •Interceptors: Implement client and server interceptors for cross-cutting concerns
- •Testing: Test gRPC services with grpcurl and other debugging tools
- •Performance Optimization: Optimize gRPC performance including connection pooling and compression

Usage Examples
Service Definition
protobuf
service Greeter {
rpc SayHello (HelloRequest) returns (HelloReply);
rpc SayHelloStream (HelloRequest) returns (stream HelloReply);
}
Testing with grpcurl
bash
grpcurl -plaintext localhost:50051 list
grpcurl -plaintext -d '{"name": "World"}' localhost:50051 greeter.Greeter/SayHello
Reflection Debugging
bash
grpcurl -plaintext localhost:50051 describe greeter.Greeter
