What
Side queries (background calls to the model, such as sub-agent or utility calls) used to have an extra block of system-prompt text appended, starting with "# Reporting outcomes," instructing the model to report what it actually did rather than what it intended to do. In the rewritten side-query builder, this block is no longer appended.
Why
This removes a reminder that previously nudged background/sub-agent responses toward describing actual results instead of stated intentions; side queries no longer carry that particular instruction.
