What

/ultrareview runs a deep code review in the cloud. Its messages have changed:

  • Stopping a review now says: Ultrareview stopped. Run /ultrareview to start a new review, which uses one of your free ultrareviews or bills as usage credits. It no longer shows a session link.
  • When Claude Code cannot check on a review, it no longer prints a session link. It says Nothing is running in the cloud. if the review never started, and otherwise says it stopped waiting and the review may still be running.
  • The text for --post no longer suggests posting the review's findings by hand.

Several other small changes:

  • /fast with nothing after it now also turns fast mode on when an additional check passes.
  • For logins using a key managed through /login, the sign-in status now shows your email, organization and organization ID.
  • In settings, the scroll arrows in the output style picker can now be clicked.
Why

The new /ultrareview messages say plainly how to start another review and what it costs, and whether anything may still be running in the cloud.

Since it was published

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Added since A small documentation edit on Code Review touched a line naming /ultrareview after this was published. To run a cloud review from a script or CI job, use the [`claude ultrareview` subcommand](/docs/en/ultrareview#run-ultrareview-non-interactively), which waits for the findings and prints them to stdout. code-review see the edit
Added since A small documentation edit on Claude Tag for Claude Code users touched a line naming /fast after this was published. | `/fast` | Once an Owner [allows fast mode](/docs/claude-tag/admins/customize#allow-fast-mode), you [turn it on for one thread](/docs/claude-tag/users/models#run-a-thread-in-fast-mode) with `@Claude !fast` | claude-tag/concepts/for-claude-code-users see the edit
Confirmed since Anthropic's documentation has since written up /fast, on Customize Claude Tag. * **Cost**: a channel thread in fast mode bills to your organization like other [channel work](/docs/claude-tag/admins/set-spend-limit#how-claude-tag-usage-is-billed), at the [fast mode rates](https://code.claude.com/docs/en/fast-mode#unde… claude-tag/admins/customize see the edit
Confirmed since Anthropic's documentation has since written up /ultrareview, on Claude Code changelog. * Fixed `/ultrareview` giving advice about `.git/info/attributes` when the upload stops on a committed `.gitattributes` it cannot read, such as one saved as UTF-16 changelog see the edit
