I like the idea of `"Please suggest 10 improvements to my ~/.zshrc"` as a prompt ([John Lindquist](https://x.com/johnlindquist/status/1993037322984866168)). Nick Taylor [wrote up all the stuff](https://www.nickyt.co/blog/how-i-used-claude-code-to-speed-up-my-shell-startup-by-95percent) it found for him and got nearly a second back for every fresh terminal opened.
