Unclear It is not clear whether this list is behind a remote switch that is off by default.
In auto mode, a safety classifier, a separate model check, reviews actions before Claude Code takes them without asking you. The context that classifier sees now includes a list of verified events that arrived through polling, which is Claude Code checking repeatedly for new messages from other agents or people.
The list has a size limit. When the classifier's context runs over its budget, the newest events are kept and older ones are dropped, and the number dropped is recorded.
This changes what the safety check knows about outside events when it decides whether an action is safe.
