Recommended action: Replace Union fields with a discriminator-free design (e.g. separate optional fields, Literal type tag + optional payloads) or use a JSON mode/provider that supports anyOf.

Applies when: Gemini function-calling modes
Steps:
1. Refactor field: kind: Literal["a","b"]; a: A | None = None; b: B | None = None
