Partially sarcastic but I do personally use LLMs to guide my communication in very limited cases:
1. It's purely business related, and
2. I'm feeling too emotionally invested (or more likely, royally pissed off) and don't trust myself to write in a professional manner, and
3. I genuinely want the message to sound cold, corporate, and unemotional
Number 3 would fit you here. These people are not being respectful to you in presenting code for review that respects your time. Why should you take the time to write back personally?
It should be noted that this accounts for maybe 5% of my business communications, and I'm careful not to let that number grow.
Because it's 3 sentences, if you want to be way more polite and verbose than necessary.
"I will close PRs if they appear to be largely LLM-generated. I am always happy to review something with care and attention if it shows the same qualities. Thanks!"
The idea is to get your coworkers to stop sending you AI slop, send them AI slop in retaliation?
And then what if the person denies it?
They're either lying about using AI, or they're incompetent enough to produce AI quality (read: Garbage) code, either way the company should let them go
