What probably matters to youSection of the release
What
Delegation guidance now says subagents run in the background, that a completion notification will arrive on its own, and that Claude must not fabricate or predict results. If you ask before the notification lands, it should say the agent is still running.
Details
Added to both the fork wording and the background-agent wording.
Evidence
Never fabricate or predict a pending agent's results \u2014 the notification is never something you write yourself; if the user asks before it arrives, say it's still running.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
