I vibe coded an Emacs package recently. I've used Emacs for years, but never done any nontrivial elisp. Couple functions here and there, and advice to modify behaviors.

It worked pretty well, but there are pretty obvious shortcomings. The code isn't very good. It has some odd design choices. But overall, it works.

I know enough elisp to modify the existing package, so I'm using the LLM less and less as time goes on (which is where I've found they mostly start to suck), but I didn't know enough to get started, so I'm happy about the outcome.
