Instance Method Details

#tool_id(part:, cindex:, pindex:) ⇒ String

Returns a stable internal tool-call ID for Gemini function calls.

Gemini responses may omit a direct tool-call ID, but llm.rb expects one for matching pending tool calls with tool returns across streaming and normal completion flows.

When Gemini provides a thoughtSignature, that value is used as the basis for the ID. Otherwise the ID falls back to the candidate and part indexes, which are stable within the response.

Parameters:

  • part (Hash) —

    A Gemini content part containing a functionCall.

  • cindex (Integer) —

    The candidate index for the tool call.

  • pindex (Integer) —

    The part index for the tool call within the candidate.

Returns:

  • (String) —

    Returns a stable internal tool-call ID.
