I think most code in this PR is for the skeleton itself, and using TryOp, not sure if there is any part that I can remove and keep the test passed. The parts that can be removed are the Attributes and their parsers/printers, but I think now they are already tested 🤔.

If needed, I can error out and move them to another PR What do you think? @bcardosolopes
