Most errors are not usage errors and shouldn't show the usage. Stuff like HTTP errors would trigger this for example

True! @f0ssel mentioned the same thing. Maybe that's why SilenceErrors is set to true?

Is there a way we can detect a cobra error like errors.Is(err, cobra.ErrArgs) or something?

I looked around the docs but didn't find anything. Seems like it just returns a regular error. Maybe someone sees something though.
