Summary

A Lobsters discussion asking whether teams allow LLMs to write both production code and tests, with the author considering a policy restricting AI generation to only one of the two to avoid tautological, over-engineered results.

<p>I'm curious what stance others have taken? Or what they've experienced with this? I'm toying with adding a rule to our values.md that the LLM can only significantly generate one or the other.</p> <p>I'm reviewing a merge request at the moment where it's clear the LLM mostly did both, and they're highly tautological. And I can see how it over engineered the code, just to be able to write more tests almost.</p>
