Yeah, I guess we're talking less about "help" (F1 in Windows, or at least it used to be) than about the user-interface guidelines that mandate the "File" dialog

Yeah, I guess we're talking less about "help" (F1 in Windows, or at least it used to be) than about the user-interface guidelines that mandate the "File" dialog and so. As for doing a "systemic exploration", this is largely the role that manpages or "-h" fills in traditional Unix programs, but you're right that we need a better solution for widespread adoption of a "modern" Slack-y CLI for nontechnical users. Maybe show HELM-style autocomplete "menu" of possible subcommands in the input area or sidebar?
