axi

AXI defines ergonomic standards for building CLI tools that autonomous agents interact with through shell execution. Read the TOON specification before building any AXI output. Use TOON (Token-Oriented Object Notation) as the output format on stdout. TOON provides ~40% token savings over equivalent JSON while remaining readable by agents. Convert to TOON at the output boundary — keep internal logic on JSON. Every field in stdout costs tokens — multiplied by row count in collections. Default to the smallest schema that lets the agent decide what to do next: typically an identifier, a title, and a status. Detail views often contain large text fields.
