NAISYS is an open source command shell proxy for LLM agents that I just released a few days ago.

It will run the agents in a wrapper around your actual shell that is context friendly. It even has a custom mail client and browser wrapper that is agent/context friendly.

I have a demo video where a Claude3 and GPT4 agent build a website from scratch together on the command line. https://www.youtube.com/watch?v=Ttya3ixjumo
