You DO NOT have to stir it, even for things like spaghetti, as long as you’re using the right amount of water. The motion of the water boiling is already stirring the pasta.
You just stir for good measure. Yeah you might not need to if you have the perfect amount of water boiling in the perfect way, but honestly it’s not worth the risk. Just stir it from time to time.
