For the specific case of solving shell script dependencies, Nix is actually very straightforward. Packaging a script is a writeShellApplication call and calling it is a `nix run`.

I guess the issue is just that nobody has documented how to do that one specific thing so you can only learn this technique by trying to learn Nix as a whole.

So perhaps the thing you're envisaging could just be a wrapper for this Nix logic.
