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)
