Event streams

Stream events until the command is interrupted:

radius events --follow --jsonl

Filter events to a window or group:

radius events --window window_1 --follow --jsonl
radius events --group group_example --follow --jsonl

Command lifecycle events

command.started
command.finished
command.failed

Each line is one JSON object:

{"event":"command.finished","timestamp":"2026-08-14T19:42:01.000Z","windowId":"window_1","payload":{"value":{"id":"tab_42"}}}

Use event streams for logging, agent observation, and coordination between long-running tools. A normal shell script that runs commands sequentially does not need to subscribe.

Events describe activity that has already occurred. Subscribing does not give the subscriber ownership of tabs or cause Radius to keep enforcing a layout.
