What
The review command's argument hint names the accepted targets instead of showing a generic placeholder.
Details
Hint now reads [--fix ] [--comment ] [<pr#>|<branch>|<path>]. The optional "ultra" level is still appended when available. Evidence
[--fix ] [--comment ] [<pr#>|<branch>|<path>]
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Names in this entry
slash /review Alias of /code-review : reviews the current diff, or a PR number, branch, or path you pass, such as /review 1234, and takes the same effort levels and flags. With no level given, the review reuses the last low through max level you typed; see Review a diff locally for the exact rules. For a deep cloud review, use /code-review ultra . Before v2.1.223, /review was a separate command that ran a single-pass, read-only review of a GitHub pull request by number, listing open PRs to pick from when run with no argument; from v2.1.186 through v2.1.201, it ran the same multi-agent engine as /code-review medium

Anthropic's note
Upstream's own release notes for v2.1.223 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.
Changed /review to be an alias of /code-review , which reviews the current diff or a PR (/code-review <level> <pr#>); use /code-review ultra for a deep cloud review
