Hi @rumstead. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

This feels like it should be in the alpha folder but since I believe I need methods from CLI I cannot use a different package.

@camilamacedo86 looking for some guidance here. Since the scaffold command will essentially do an init + edit + create, I need access to thecli package.

EDIT: I could create an instance of CLI in the scaffold command but that would be a circular dependency since a CLI instance creates a scaffold command.
