Under the hood
The reminder-toolsearch-deferred prompt was rewritten with guidance to finish the whole task before reporting done
What
The system prompt text used in the reminder-toolsearch-deferred context (shown when a deferred tool needs to be looked up via ToolSearch) was rewritten. The new wording says to finish the whole task, not just the easy parts, and to report completion only when fully done.
Why
This pushes Claude to complete a task in full, including after it has had to pause to look up a deferred tool, rather than reporting it as finished prematurely.
