Ugh, I have to deal with someone who is bad at this. He regularly sends out emails that include all the devs pointing out that someone broke the build (worth pointing out if they didn't already see the automated email - not worth humiliating them in front of the whole team), and then also tries to show the fix that will be needed.
On the one hand, when he's right (which is often) it can save some work, but on the other hand, he's not always right, and he always sounds like an ass.
I've repeatedly asked management to have a word with him about it, but they haven't because he's a valued team member and they don't want to rock the boat. I ended up blowing up at him over email about it and he's definitely been less of a dick to me about these things, but he continues to be a dick to everyone else about it because it makes him look smarter. It's pretty irritating and I never want to have to work with him again because of it.
E.g. "this will make me look so much smarter"
