It writes more informative commits than I could ever make so I'm just reading what it says and mostly copy/pasting completely most of the time, I write all of the changes I've made into an LLM with a large context window and it write a very detailed commit not just with a title but with bullet points describing each of the changes precisely
Im shocked at all the negativity, this seems like an obvious good usecase to me, and I'm someone who finds most AI predictive stuff useless.
I never take more than 3 sec on my commit messages, most of them are "fix bug", "update lib", "bump". So it's a pretty low bar for it to make better messages than mine.
I make really small and really frequent commits. Like I'll commit all changes every 10 min regardless of if a feature is done or not, and basically use commits like an undo button.
I still use git history a lot (per file history usually) but even when browsing years and hundreds of commits into the past, I don't really need detailed/thoughtful messages to find the change I'm looking for. Binary search plus those 2 or 3 word message hints are lightning fast. And the number of times I commit vastly outweighs the number of times I browse the history.
When it comes to documentation and other people, feature-branches are my "OK I fully finished this thing; here's a summary". I'm also not afraid to squash a ton of useless commits together right before making a PR.
TDLR; spending more than 3 sec doesn't help future me or current me, so it's a waste of time
