Agent2Agent Protocol

Start by opening the official documentation for Agent2Agent Protocol and identify the smallest workflow that demonstrates open protocol for discovery, communication, task delegation, and interoperability between independently built AI agents. Use the documented quickstart rather than copying an old community example, because AI SDKs and hosted endpoints change frequently.

For a local or self-hosted setup, create only the credentials and permissions required by the test. Keep secrets outside source code. If the project is open source, pin a known release and use its supported runtime or container instructions. If it connects to external models, tools, documents, browsers, or databases, begin with a disposable test environment.

Run a representative task and inspect both the result and the intermediate behavior. For agents, check tool calls, retries, state, and stopping behavior. For retrieval or document systems, inspect parsing and retrieved context. For evaluation or observability tools, create a small dataset or trace set and confirm that the metrics reflect failures you actually care about.

Before production use, test latency, cost, error handling, privacy, and access boundaries under realistic conditions. The current catalog pricing classification is free, but commercial plans and usage limits can change; confirm the latest terms on the official product site.
