What

The system prompt text used in the reminder-read-offset context (shown when a file read uses an offset) was rewritten. The new wording says to interpret ambiguity the way a careful colleague would: make routine judgment calls independently, and only check in with the user when different readings of the task would lead to materially different work.

Why

This guides how much Claude should ask versus decide on its own when a task is ambiguous, aiming to cut down on unnecessary check-ins while still flagging genuinely consequential ambiguity.
