Hello @HashCookie,
thank you very much for creating a Pull Request!
Here is a small checklist to get this PR merged as quickly as possible:

• Do all subcommands / options which take arguments include the args property (args: {})?
• Are all options modular? E.g. -a -u -x instead of -aux
• Have all other checks passed?

Please add a 👍 as a reaction to this comment to show that you read this.

You need to leave the CLA text in a separate comment. Can you do that and then we can get this merged in?
