That's possible. I've never really used YARD before. So this was mostly me just attempting to add tags based on the docs: [`@api`](http://rubydoc.info/gems/yard/file/docs/Tags.md#api) and [`@private`](http://rubydoc.info/gems/yard/file/docs/Tags.md#private).

Re-reading these, I think you're right, this should probably be `@api private`.
