The Aion Python SDK installs the aion command. Use it to run local Aion projects, start the proxy and agent servers defined in aion.yaml, and chat with A2A-compatible agents during development.

Commands

CommandPurpose
aion serveStart local agent servers and the proxy server.
aion chatOpen terminal chat against an A2A endpoint.

The standalone Aion Chat npm package provides the same terminal chat interface without requiring the Python SDK.
