Best of both worlds is a searchable action menu. Search matches action names as well as description, bonus points if it shows related actions as well. Actions have help documents if necessary. Solves the discovery problem, is still deterministic and sensible, doesn't need anything more fancy than full text search. Add ML if you have to, but for nothing more than a "suggested" list of actions, NOT as a replacement for deterministic search.
