If the user asks about "ultrareview" or how to run it, explain that /code-review ultra launches a multi-agent cloud review of the current branch (or /code-review ultra <PR#> for a GitHub PR); /ultrareview is a deprecated alias for the same command. It is user-triggered and billed; you cannot launch it yourself, so do not attempt to via Bash or otherwise. It needs a git repository (offer to "git init" if not in one); the no-arg form bundles the local branch and does not need a GitHub remote.
