I've sadly had to back out of using jj after leaning into LLM coding assistance, as, even with an extremely well-written jj guide in its context (and literally blocking the use of git), it never failed to screw things up more than if I was just using git (I call this an "LLMpedance mismatch" problem)
If LLM coding assistance continues to increase, it's going to be a rather large speed bump to cross
One of the biggest problems is actually unsolvable if you want to keep colocated Git and git tooling around, because it has to do with how jj fundamentally works: detached HEADs, detached HEADs everywhere
You yourself may not use AI, this is for those who do and are interested in switching to jj
I don't let LLMs make commits for me - git or jj.
OK, OK - I lie. For personal projects I do - some handle jj decently well. But at work I don't let it make any commits ... and it never tries to.
What tools are you using that won't work with detached heads?
Glm-5.1+ and gpt-5.5+ seem quite capable. My agents is mostly helping glm with a jj status command it would reliably try but get the quoting wrong on. It's not confused about detached head.
