I would love for someone to package up some kind of script or AI skill that evaluates your current terminal config/set-up and applies all of these tips and tricks. For instance, it might detect that you currently use ag, install ripgrep, and offer a short tutorial on how users accustomed to ag should use it. Or it might look at the history of git commands you've run and offer tips on efficiency improvements.

Going from ag to ripgrep is not unequivocally better. Sure ripgrep is faster, but its file filtering using -g is so much more cumbersome than -G in ag. The latter uses a regex and the former uses glob. I type many more characters to do the same search, and the same search is maybe 0.1s faster for a medium codebase. So no for me. Maybe it’s worth it for a larger codebase that isn’t large enough to require indexing.

I doubt you need a full script or skill for that. I would try something like this straight in Claude Code (and will as soon as my 5 hour quota resets :-): Review this page: https://will-keleher.com/posts/small-programming-tricks-matt... Then, review my shell init scripts (both bash and fish) and shell history. Make recommendations based on the tips and tricks from the page.

I think it's a great way to stop understanding what's going on in your terminal.

IMHO the value of these nuggets is that you understand what you're doing and why; opening yourself to large amounts of non-default behavior likely will end up in a less than pleasant setup.

Not taking into account that different users might disagree on what is convenient and what is not, which is basically the point of making things configurable.
