I often do the reverse -- have LLMs insert docstrings into large, poorly commented codebases that are hard to understand.

Pasting a piece of code into an LLM with the prompt "comment the shit out of this" works quite well.

Matheus Pedroni released a really clever plugin for doing that with LLM the other day: https://mathpn.com/posts/llm-docsmith/

You run it like this:

  llm install llm-docsmith
  llm docsmith ./scripts/main.py
