Generation

As explained in Build an AI Agent (From Scratch)

A task response is a standardized A2A message returned by an agent server with the result of processing a task request.

Generation is the server-side production of a standardized A2A task response after processing a client request. A2A defines the exchange format while HTTP carries communication between clients and agent servers. section 9.6.1

A typical generation flow has three stages:

  • The client queries an agent card to discover the agent’s identity, capabilities, and endpoint. section 9.6.1
  • The client sends a task request to the endpoint specified by the agent card. section 9.6.1
  • The server executes the agent and returns the task result in the standardized response format. section 9.6.1

Math-agent response flow

A client discovers a math expert through an agent card describing mathematical calculation and equation-solving capabilities. It sends a task to the advertised URL, and the server processes the task before returning the result. section 9.6.1

How Build an AI Agent (From Scratch) covers it

How deep it goes
Explains the request-response flow and HTTP role but does not detail the response schema or server implementation.
Examples
Uses a math expert agent card and a client-server flow showing discovery, task submission, execution, and result return.
What it assumes
Assumes familiarity with HTTP clients and servers while explaining agent cards and task exchanges directly.
What you can do after
Understand how to trace an A2A task from agent discovery through server execution to the returned response.
How it connects
Connects task response with agent cards, task requests, agent servers, clients, capabilities, and HTTP communication.
