### Search before asking - [x] I searched in the [issues](https://github.com/apache/flink-agents/issues) and found nothing similar. ### Description @wenjin272 suggested this on #1129. A `RowTypeInfo` output schema never gets native structured output today: - The native connections accept only a POJO class (Java) or a pydantic model (Python), so they skip a `RowTypeInfo`. - The prompt path describes the schema with the type's string form (`toString()` in Java, `str()` in Python), not JSON Schema. - The Java `BaseChatModelConnection.chat` Javadoc calls the skip a permanent fallback. Proposal: render a flat `RowTypeInfo` (basic field types only) as a JSON Schema object, in both languages: - every field required - `additionalProperties: false` Use it in two steps: 1. In the prompt, in place of the string form. 2. As the native schema, so `AUTO` and `NATIVE` work for a `RowTypeInfo`. The connections currently take a class, so this step needs them to accept a schema document as well. A nested or non-basic `RowTypeInfo` keeps today's behavior. The guide and the Javadoc above are updated to match. ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
