Yaasnippet is for writing software boilerplate via customisable macros. If you just want to look up documentation we actually have several tools for that already, which have the benefit of empowering you. (EDIT: this is too glib. I mean to say that documentation is more reliable, and because it is structured carefully by humans - some better at doing so than others admittedly - you pick up the overall structure and purpose of things. Computing stops being a set of weird specific magic spells and you start being able to solve your own problems. Or "are you saying I'll know how to use xrandr?" "I'm saying you won't have to")

However, what I am talking about is what happens when you start using a new piece of software that didn't exist or wasn't popular when the llm was trained? The information will be out of date and the answers not useful.

Also move off X lol. Wayland finally landed, it's actually good now. X11 is deprecated and only receiving maintenance patches. Automation is a bit fiddlier but the upside is a random piece of software can't send your entire screen to someone else.
