Don't send AI output you haven't reviewed, ever.
This point can’t be made enough. I’d generalize it to “Don’t send other people AI output of any kind that you haven’t bothered to fully review yourself”.
Don’t file pull requests with code you haven’t reviewed yourself.
If you open a PR with hundreds (or thousands) of lines of code that an agent produced for you, and you haven’t done the work to ensure that code is functional yourself, you are delegating the actual work to other people.
They could have prompted an agent themselves. What value are you even providing?
