The help text says that the required format for the repo settings comamnd is:
spaid_gh_set_repo_settings [<org>] [<repo>]
But it actually requires a slash instead of a space as the separator:
spaid_gh_set_repo_settings [<org>]/[<repo>]
Further down in the help text, a slash is also used.
Note that for the command to create a repo from local, a space is required and a slash will not work:
(the repo check passed and it looks for a description next)
Unless there is a reason for using space in one case and slash in another, it would be helpful to harmonize them (my vote would be to use a space as the separator for both).
