discussion - self-completing commends about usage HOT 1 OPEN

yes, this is table-stakes. In fact what I need usage for currently is the ability to "mount" one CLI into another for mise run .... I haven't fully figured out how this will work but right now but in usage-cli I'm thinking the commands to build completions and stuff could accept a command string, e.g.:

$ usage complete-word -x "mycli --usage"

And it would exec mycli --usage, get the dynamic definition, and be able to complete against it.

But it may make sense to configure this by putting it into the spec itself, maybe we could add a param like this:

fetch_spec "mycli --usage"

I don't love that name but something like that.

from usage.
