• add_vocab

• helper_credential

• goals

  Lists the guiding stars (goals) of this call: goals bound to the call first, then goals the owner pinned for the account; only open ones, at most 3. Returns {ok, room, goals: [{nr, title, done_when, source}], hint, levels}. A step that serves one can carry goal: nr on status, ac…
