This situation reminds me of the Visual Basic apps in the nineties. It was possible to write good quality software with VB and some people did. Nonetheless the majority was dross and the fact that an app was written in VB was a strong indicator of poor quality.
Agents are really good at writing unit tests, but only if you clarify exactly WHAT should be tested. Otherwise they generate slop which passes, but don't catch any bugs nor regression.
As usual, it is low quality and has zero tests.
