Just today I had an agent add a fourth "special case" to a codebase, and I went back and DRY'd three of them.

Now I used the agent to do a lot of the grunt work in that refactor, but it was still a design decision initiated by me. The chatbot, left unattended, would not have seen that needed to be done. (And when, during my refactor, it tried to fold in the fourth case I had to stop it.)

(And for a lot of code, that's ok - my static site generator is an unholy mess at this point, and I don't much care. But for paid work...)
