Thanks! good catch :) I was wondering whether there's any quality-of-life / syntactic glazing automation we can offer for secret events, for example: jhack fire [<secret label>]-secret-rotate --> automatically fetch the ID and inject it in the ENV... Would that be useful?

Yeah, I was wondering about that too. Secret labels are a bit weird though, as a secret can have both consumer and owner labels. Perhaps you could add --secret-id and --secret-label args for that event. Or perhaps what you have now is enough, but you could add some usage examples for these events to the help.
