klyn.llm.ToolCall.extraContent
property

    public readonly property extraContent as Map<String, Object>

Description

Provider-specific metadata attached to the tool call.

OpenAI-compatible gateways can expose non-standard fields needed to replay the assistant message exactly. Gemini, for example, returns `extra_content.google.thought_signature` for tool calls; this metadata must be sent back unchanged with the `tool_calls` history entry.
