Prefer returning structured values from command handlers. Milo can format those values for humans, serialize them for --format json, and expose them as MCP structuredContent. Return value Use it for str Short human-readable text dict Named structured result list Collections and tables int / float / bool Counters, measurements, and flags None Commands whose useful result is an explicit side effect For agent-facing commands, avoid requiring clients to scrape terminal prose. Return data and use Context helpers for optional human-facing logs.
