I was indexing some of Georgi Gerganov's llama.cpp code yesterday with DoctorGPT (https://github.com/FeatureBaseDB/DoctorGPT/tree/main#readme) and was thinking about doing what you are doing with CodeZen regarding reading in a whole repo. I see you have some limits in indexing larger files and have used a solution for that in DoctorGPT. I'll dig into your code and maybe we can chat about it if you are interested.
