Agent to Agent Protocol

Agent to Agent Protocol

Six pieces of the A2A protocol you need before two independent AI agents can actually work together — taught the way a patient tutor would: a mental-model card, a small story with real numbers, a Your Turn you attempt yourself, then the full solution and why it works.

— someone who has built a single AI agent and now needs it to talk to agents built by someone else

What's inside: Agent Card, Task, Message & Parts, Artifact, Task Lifecycle, Transport & Streaming.

Every section follows the same shape: a mental-model card anchoring the new idea to something you already know, a small story with real numbers, a Your Turn you attempt yourself, then the full solution and why it works.

16 pages. Real code for every fix. No filler.
