a2a-client

You build an A2A client by fetching Agent Cards for agent discovery, sending tasks in synchronous or streaming modes, and handling task states like completion, failure, or input requirements for multi-turn conversations.

In multi-agent systems, an Agent Card is a metadata descriptor that an A2A client fetches to discover available remote agents and understand their capabilities before delegating tasks or initiating communication.

Task delegation using the A2A protocol involves your client sending messages to a discovered agent and handling responses through orchestration patterns like sequential or parallel delegation, conditional routing, and fallback mechanisms.

Yes, the A2A client handles multi-turn conversations by managing complex interactions and specific task states where agents require further input before proceeding to completion.

Yes, A2A client development supports sending tasks and receiving responses in streaming modes, allowing real-time updates alongside synchronous message processing and handling various task states like failure or input requirements.

For multi-agent task delegation, you can implement orchestration patterns including sequential and parallel delegation, conditional routing, and fallback mechanisms to manage task states and agent communication effectively.
