# Interface: GeminiFunctionResponse

Defined in: [src/batteries/llm/gemini\_generate\_content/types.ts:112](https://github.com/NHTIO/ADK/blob/v1.20261003.0/src/src/batteries/llm/gemini_generate_content/types.ts#L112)

The result of a function invocation, sent back on a `user` turn.

## Remarks

`name` is the DECLARED FUNCTION NAME, not a call id — Gemini has no `tool_call_id`. A mismatched
name is a common source of opaque `INVALID_ARGUMENT` rejections.
