Depends on the prompt I think. If it's just "Generate tests plz" then I agree, but if its

"If this PR adds any new endpoints, ensure that there are functional and integration tests. If there are not, please investigate the feasibility and appropriateness, and create functional tests using the guide found on our wiki for guidance https://www.ourdevwiki.site/how-to-make-functional-tests" then maybe it could add some value.

But that very much depends on the specific system. Some tests are obvious, some not so much.
