Sorry it's taken me a while to come back to this!! I think this is a solid effort and a valuable addition, in trying to use it I'm finding it awkward — pretty heavily reliant on knowing what terms are available, and the cooldown makes trial-and-error tough. I'm down to merge this though and iterate, merge whenever you're comfortable 👍

(Failing check is expected, non-org contributions fail cuz of a permissions bug that hasn't been worth chasing down yet)

This is maybe a candidate for swapping out to a slash command + autocomplete, I think there's prior art for that in #241
