It's a lot easier to just use your IDE for a lot of these things. I haven't really used VSCode, so I don't know if it's as capable as the Jetbrains tools, but Jetbrains has had Live Templates for things like switch statement bodies for many years. If you learn how to make custom ones that prompt you for variables, it blows anything AI can do out of the water (no mistakes--it's your own code!). You don't need to look up Git commands--the Git integration lets you do everything through a seamless UI.

AI can be really useful for putting together regular expressions, though.
