Unclear It is not clear whether this tool and its new text are in use in any live prompt.

What

The text that describes the idle-wait tool to Claude has been reworded. A tool here is an action Claude can take. The text now says that a result reporting no event can come at the same time as a scheduled prompt or a message held for the end of the turn. It also says those arrive only after Claude ends its turn.

Why

If this text reaches Claude, it changes how Claude handles waiting for events. The captured prompts show no change, so the text may not be in use yet.
