Deep Feed handoff router compatibility guard
Purpose
The standalone router entrypoint is retired. Protocol v2 handles routing as an
optional, owner-confirmed branch inside the dedicated $deep-feed-work task.
This skill exists only so an old prefilled router command fails safely.
Workflow
Accept exactly one opaque
handoff-...ID.Fetch it read-only:
deep-feed-handoff get <handoff-id> --role routerNever claim, dispatch, queue, acknowledge, or update the record.
For protocol v2, tell the user to run
$deep-feed-work <handoff-id>in the newly opened task. Do not create or send another task automatically.For protocol v0/v1, explain that the old router/fallback path is frozen as readable history. If the record already has an exact destination URL, offer that only for reviewing its existing result; do not revive work.
Hard boundary
Never use left_queued, take_fallback, send_message_to_thread, or any
scheduled task as a destination. A closed or expired router is not permission
to choose another owner.
