Command Line Interface

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

Command	Purpose
`aion serve`	Start local agent servers and the proxy server.
`aion chat`	Open terminal chat against an A2A endpoint.
`aion --help`	Show CLI help.
`aion --version`	Print the Python SDK CLI version.

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