A lot of folks have been praising the harmony of Claude code + nixOS. For those of you doing this, I would recommend you to ask your agent to switch your config to nix flakes. It's a much better paradigm for working with the versioning than the default channels interface. Additionally, you should ask your agent to look into home manager, if it hasn't done so already.

It's also decreased the friction of finding software that hasn't been given a package for Nix yet but can't run on it.

I just go into the directory with the software and tell Claude Code to make me a Nix shell or a Nix flake that can run the software. Then usually within a couple minutes it'll work out what it needs to run and build it.

I recently did the same thing with ComfyUI which I was running through Conda. I had Claude code go through and figure out how to make it run just in a plain nix shell with a venv. (I always struggled getting it to recognize my NVIDIA GPU without Conda)
