What's Wrong?

When attempting to schedule a follow-up task during an active scheduled task session, the system returned:

"Cannot create scheduled tasks from within a scheduled task session."

This restriction is unexpectedly limiting — a common use case is for a scheduled task to queue a follow-up task based on its findings. There is no apparent technical reason this should be blocked, and the error message provides no workaround.

Steps to reproduce:

Create a scheduled task that runs once (one-time fireAt)
When the task fires and the session opens, attempt to create another scheduled task
Error is returned
Expected behavior: Scheduled tasks should be able to create follow-up scheduled tasks.

Environment: Claude Code on Windows 11
