Not a fan of the LLM-flavoured headings, and the tips seem like a real mixed bag (and it'd be nice to give credit specifically to the readline library where appropriate as opposed to the shell), but there are definitely a few things in here I'll have to play around with.

One thing I dislike about brace expansions is that they don't play nicely with tab completion. I'd rather have easy ways to e.g. duplicate the last token (including escaped/quoted spaces), and delete a filename suffix. And, while I'm on that topic, expand variables and `~` immediately (instead of after pressing enter).

Not just the heading is LLM-flavoured. So is the writing, e.g. "The shell is a toolbox, not an obstacle course."

Speaking of readline, I recently found out PowerShell has a readline mode (https://learn.microsoft.com/en-us/powershell/module/psreadli...) and it works great.

As someone who works mostly in WSL and has to use PS occasionally, it really reduces the overhead of the context switch.

Readline is close enough to being part of bash that it’s not really inaccurate to call these all shell features imo.
