DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Slash commands

/ultrareview

A Claude Code slash command, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Run a deep, multi-agent code review in a cloud sandbox with [ultrareview](/docs/en/ultrareview). 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](https://support.claude.com/en/articles/12429409-extra-usage-for-paid-claude-plans)

Anthropic's own wording. Read off Commands, captured 2026-08-28.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

  1. v2.1.227/ultrareview can post its findings to a GitHub pull request

    /ultrareview takes --post and --no-post to comment findings on a GitHub PR as you.

  2. v2.1.227Posting /ultrareview findings to a pull request can now be turned off remotely

    A server switch can remove the post-to-PR option from ultrareview; it defaults to available.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the slash command does. All slash commands.
