View Source LlmComposer.Message (llm_composer v0.19.2)

Module that represents an arbitrary message for any LLM.

Fields

:type — the role of the message sender (e.g. :user, :assistant, :system, :tool_result).
:content — the text or structured content of the message.
:reasoning — optional plain-text reasoning string returned by reasoning models. Primarily used with OpenRouter: when an assistant message is included in a follow-up request, this field is forwarded so the model can continue from where it left off.
:reasoning_details — optional list of reasoning detail objects (maps) returned by reasoning models. Use this instead of (or alongside) :reasoning when the provider returns structured reasoning blocks (e.g. encrypted or summarised thinking blocks). Like :reasoning, this field is forwarded by the OpenRouter provider on resend.
:function_calls — optional list of LlmComposer.FunctionCall structs returned by the model when it requests tool execution. Set by parsers on assistant messages.
:metadata — arbitrary map for provider-specific data (e.g. original raw response).
