I really like the repo-mix tool for generating targeted LLMs.txt files.

https://github.com/yamadashy/repomix

I use this in a pre-commit hook to generate a few versions of these (of various token lengths) in Langroid:

For example I can dump one of the LLMs.txt into Gemini 2.5 pro and ask it about how certain Langroid features work, or ask it to implement simple agent systems, and it does a good (not perfect) job. I find this to be a convenient way to onboard people to Langroid, since LLMs don’t (yet) “know” Langroid too well (they know a little and hallucinate quite a bit)
