Why is it "make" here

but "add" here?

I suggest replacing these verbs with the verb "create".

make_portal sounds better than create_portal :D

and add wrapping is better than create wrapping or make wrapping

?

Do you mean using the same verb for just the wrapping commands? Since in that case, I would not mind if make_small_inward_wrapping was changed to add_small_inward_wrapping and etc.

I am considering changing them to "create" except for "make_portal"

Yes
