How to let a enchant level limitation, such as sharp enchant books need reskillable: attack | 12 can be used on the anvil. Or with a sharp enchant weapons need reskillable: attack | 12 to use.

I don't know if you can lock anvil recipes, but it is possible to lock items based on NBT data with ZenScript. I have an old example script I wrote a while back that may be helpful for you.
