alt Hacker NewsI'm very sceptical on how well AI can "read the full diff and summarise the changes properly".
A colleague has been using Claude for this exact purpose for the past 2-3 months. Left alone, Claude just kept spewing spammy, formulaic, uninteresting summaries. E.g. phrases like "updated migrations" or "updated admin" were frequent occurrences for changes in our Django project. On the other hand, important implementation choices were left undocumented.
Basically, my conclusion was that, for the time being, Claude's summaries aren't worthy for inclusion in our git log. They missed most things that would make the log message useful, and included mostly stuff that Claude could generate on demand at any time. I.e. spam.
Same experience here, I see many people in the company (5-10k employees) pushing commits with Claude-generated comments that are absolutely useless.
I got praised for my commit messages by another team, they asked me how I was making Claude generate them, and I had to tell them I'm just not using Claude for that.
I like writing my own commit messages because it helps me as well, I have to understand what was done and be able to summarise it, if I don't understand quickly enough to write a summary in the commit message it means something can be simplified or is complex enough to need comments in the code.
