I received feedback from my manager that a colleague found a code review comment of mine hurtful. He kept the name confidential.
It's important to me that code review remain a positive and collaborative interaction, so this is deeply concerning to me.
I looked over my recent comments and did not find anything that seemed objectionable to me - but that's the problem in a nutshell, isn't it?
What, if anything, should I do in this situation?
