A Go CLI tool that injects custom struct tags into generated Go protobuf (.pb.go) files using @gotags comments in .proto files. It works as a post-processing step after protoc code generation, commonly used for validation and JSON field control.

Use cases

• inject custom struct tags into generated protobuf Go code
• add validation tags to protobuf-generated structs
• control JSON serialization of protobuf messages in Go
• post-process .pb.go files after protoc generation
• remove tag comments for OpenAPI/Swagger generation compatibility

When to choose

• you use protoc-gen-go and need struct tags it doesn't support natively
• you want validation or JSON tags on protobuf-generated Go structs
• you need a simple post-generation step in your build pipeline

When to avoid

• you use protoc plugins that support custom tags natively
• you don't generate Go code from protobuf
• you want tags injected at protoc plugin stage rather than post-processing
