The result returned by the client for a CreateMessageRequestsampling/createMessage request. The client should inform the user before returning the sampled message, to allow them to inspect the response (human in the loop) and decide whether to allow the server to see it.

The reason why sampling stopped, if known.

Standard values:

• "endTurn": Natural end of the assistant’s turn
