Class MessageDescriptorToSchemaConverter

java.lang.Object

dev.enola.common.protobuf.schema.MessageDescriptorToSchemaConverter

public class MessageDescriptorToSchemaConverter
extends Object

Conversion from Protocol Buffers (model, not instances) to Google GenAI Schema (which is based on OpenAPI 3.0 schema, which in turn is very much like JSON Schema).

The Schema matches how a Proto message (instance, not model) would be serialized in ProtoJSON format.

Other than just being 💃 fun, this is (very) useful to be able to 🧑🏽‍🍼 feed 🥄 Language Models, such as Google 🔮 Gemini, 🥢 Protos instead of only 📜 text, for 🧰 tools (whether through MCP 🔱 or not), or to configure their expected structured output.
