public record MessageSendParams(Message message, @Nullable MessageSendConfiguration configuration, @Nullable Map<String,Object> metadata, @Nullable String tenant) extends Record
Parameters for sending a message to an agent in the A2A Protocol.

This record encapsulates the message content, optional configuration, and metadata for agent task requests. It is used to define what message to send and how to process it.

The message can create a new task, continue an existing task (if it contains a task ID), or restart a task depending on the agent's implementation and the message context.
