I’ve been using LLMs (the new Deepseek) on Clojure and it works well. The only major pain point is that it sucks at getting the last paren on. There are hooks that will fix that automatically, but I’ve been lazy.

I haven’t tried on anything completely blank, though. My projects have been sort of skeletons where I’m figuring out what I want it to look like, and it’s pretty good at imitating the patterns. Like I write functions to query a particular SQL table, and it can pick up how to use the SQL generation library from that.

It works pretty well. I also have it generating good docstrings though, which might help. Every function gets a “what does it do, why would you use it, what does it expect as args, what does it return” comment. If the function expects a map, the comments specify the keys it needs and so on.

You can also get typing (sort of) by using Malli or similar which does both runtime checking of schemas and serves as documentation of what the expected shape of the arg is. The LLM has been pretty good at falling back to looking at the schema if tests fail because of validation issues.
