What
Programs driving Claude Code through the SDK get more detail about work running in the background.
Details
- A new
background_tasks_changed system message carries the list of active task ids. - Task status updates include
is_backgrounded; task_notification gains a status. turn_starting now carries a mode, plus the task_id when that mode is task-notification.
Evidence
background_tasks_changed
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
