The information I’ve found consistently says it’s okay to just add them, as this Extension Service article says. I find recommendations to break them up so water doesn’t sit & rot in a half-shell. Some people wash, dry, and grind them, like in a blender, before adding to compost. They take a year or more to break down and finely crushing means they are not visible in the compost when you use it.
Here’s an article about composting in general.
I did find this set of training slides which says on #25 to wash egg shells.
