/ultrareview

Runs a deep, multi-agent code review in a cloud sandbox.

Pass a PR reference to review that pull request, or a branch name to change the comparison base. The preferred invocation is now /code-review ultra, and /ultrareview remains as an alias. Includes 3 free runs on Pro and Max, then requires usage credits.

✅ WHEN TO USE IT?

Have a pull request reviewed thoroughly

/ultrareview 42

Compare against a different base branch

/ultrareview main

⛔ WHEN NOT TO?

A quick local look at a small change

/ultrareview launches a heavy cloud review; that is overkill for a quick glance.

Better: ask Claude directly to look over the local diff
