Remarks
Each notification carries a complete task state for the current status, identical to what
tasks/get would have returned at that moment. The concrete type depends on the task's
current status:
- WorkingTaskNotificationParams — Working
- CompletedTaskNotificationParams — Completed
- FailedTaskNotificationParams — Failed
- CancelledTaskNotificationParams — Cancelled
- InputRequiredTaskNotificationParams — InputRequired
To receive task status notifications, clients send a subscriptions/listen request
including the task IDs they are interested in.
See the SEP-2663 specification for details.
