This looks really useful — occasionally I run into the issue that I'm on an odd machine with minimal packages installed, and want to use AI to do some stuff without setting up a full Node/Python environment. This seems like the perfect solution for that.

Is it possible to download just the binary itself, without needing to run the install script which installs it globally?

Your getcook.dev tool has a nice form factor for a coding agent, keeping users out of a TUI, instead staying on the command line. An option I'd be interested in exploring is one that wraps `claude -p`, reads the jsonl of that session and prints it out nicely like you are doing with getcook.dev.
