# Generating gRPC Services ## Overview Generate gRPC service definitions, client/server stubs, and implementations from Protocol Buffer (protobuf) `.proto` files. Scaffold unary, server-streaming, client-streaming, and bidirectional-streaming RPC methods with proper error status codes, interceptors for auth/logging, and health check service registration. ## Prerequisites - Protocol Buffers compiler (`protoc`) v3.21+ installed - Language-specific gRPC plugin: `grpc_tools_node_protoc_plugin` (Node.js), `grpcio-tools` (Python), or Go gRPC plugin - `buf` CLI for proto linting and breaking change detection (recommended) - gRPC testing tool: `grpcurl`, `evans`, or BloomRPC - TLS certificates for production transport security (mTLS recommended for service-to-service) ## Instructions 1. Read existing `.proto` files using Glob and Read, or design new service definitions with message types, RPC methods, and streaming patterns per service requirements. 2. Define proto3 message types with appropriate field types, using `google.protobuf.Timestamp` for dates, `google.protobuf.Struct` for dynamic fields, and `oneof` for polymorphic messages. 3. Compile `.proto` files with `protoc` to generate language-specific stubs, server interfaces, and client libraries using the appropriate gRPC plugin. 4. Implement server-side RPC handlers for each method, returning proper gRPC status codes (`OK`, `NOT_FOUND`, `INVALID_ARGUMENT`, `PERMISSION_DENIED`) instead of generic errors. 5. Add server inter...
