You can get my latest catppucin mocha starship-configs (blue-ish gradient, green & red) from my stellar profile, or just use your own ones. If using yours make sure to adjust the names of the themes.
Warning
I would recomend using stellar instead, I wrote it a little bit after this script here, and it has a few more features, you can switch between local starship configs, as well as easily install starship configs from the community
