This is my take on it too. And I built BetterGit (https://www.satishmaha.com/BetterGit/) before agent capabilities became widespread. A lot of things in Git and existing GUIs are just cumbersome, and my app makes it better to handle the most common tasks and makes them easier. It's really meant for newcomers to Git.

BUT! You can simply ask an agent to commit every meaningful block of work. Or just ask any agent to create a JIRA ticket and start work on that named branch. Or ask it to create work trees and create a PR. Life has gotten much easier without having to fight the command line or confusing GUI UX.

JJ is a whole different way to think about source control. The fact that you don’t need to run an agent just to use it is a nice bonus.

You can also have you agent use jj with this skill

I am a really heavy Claude Code user but source control is still one area where I have regular bad experiences just using Claude.
