I am making a module that has useful built-in functions for a character. What else shoud I add?

So, I am making a module called CharacterService, and it has functions for a chraracter. Like it checks if a model is a character, or a function that gets all the character’s limbs. I don’t know what else to add, any thoughts?

Maybe add a function that finds the HumanoidRootPart coordinates

Can’t you just get the HumanoidRootPart’s CFrame for that?

Yes you can, but a function to get the coordinates is way more faster.
