Connect to Remote Agents with ADK and the Agent2Agent (A2A) SDK

Why it matters

A2A coordinates independently deployed agents; it is not interchangeable with exposing a tool over MCP. The lab makes the discovery and interaction boundary observable.

What to practise

Deploy an agent as an A2A server, publish its Agent Card, and configure another agent to discover and call it as a remote collaborator.

How it fits

Use the exercise after subsection 3.3’s protocol, workflow, routing, and handoff Bites. Identify which responsibilities stay with each agent and which cross the protocol boundary.
