Agent prompt
what a new run launched now would send
filter on exists-subquery with empty queryset removes whole WHERE block
Description
(last modified by Tobias Bengfort)
>>> qs = MyModel.objects.filter(~models.Exists(MyModel.objects.none()), name='test')
>>> qs
<QuerySet []>
>>> print(qs.query)
EmptyResultSet
With django-debug-toolbar I can still see the query, but there WHERE block is missing completely.
This seems to be very similar to #33018.
Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.
When you are done, leave your changes committed or in the working tree;
they are collected automatically.
Stay on this snapshot checkout (`task/ycb_django_pr15382`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.
Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
