InteractionStreamUserNotification

What the interaction-process-stream event carries: a piece of an agent’s reply as the model writes it, or the name of a tool it is calling. Best effort: pieces are never replayed, so read the run for the full text.

Kind: an object, used in responses.

Fields

Every field is present in a response; empty ones are null.

Field	Type	Description
stream	string	The new text: the next piece of the reply, or the tool’s name.
sequence	integer	A number that orders the pieces of a reply, in case they arrive out of order.
associatedId	uuid	The id of the interaction run.
agentName	string	The name of the participant that is writing.
date	datetime	When the piece was written, in UTC.
type	AiStreamingMessageType	Whether this is reply text or a tool call.
