I don't plan for all of them. Just when I realise some specific one is getting too repetitive, I make a script for it. Never needed to do so at home (yet), because my IDEs usually provide good enough boilerplate and I am mostly doing learning projects (i.e. hardly any repetition), but I did make a few in one of my previous work places, which someone else might be using rn (hopefully not, because it was meant for me and not for users).
