What
The system prompt text used in the reminder-read-dup context (shown on a duplicate file read) was rewritten. The new wording says that if a real problem is found with the task as specified, Claude should state the concern in a sentence or two, then keep building: delivering the complete work under explicitly stated assumptions while flagging important factors for the user.
Why
This is guidance for how Claude should respond when it spots an issue with the task while re-reading a file, favoring flagging the concern and continuing over stopping or silently changing scope.
