What
The help text for /review , the alias of /code-review , now says the review runs "at the effort level given first, before any target". It used to say only "at the given effort level". Other parts of the description were shortened.
Why
The help text now spells out the argument order: type the effort level before the pull request number, branch or path you want reviewed.

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
slash /code-review Skill . Review the current diff, or a PR number, branch, or path you pass, for correctness bugs. Depending on your model and effort level, the review also covers cleanup opportunities. Pass --fix to apply findings, --comment to post them on the GitHub PR or GitLab merge request, or ultra to run a deep cloud review . Posting to a GitLab merge request requires Claude Code v2.1.257 or later. With ultra on a github.com PR target, pass --post to preselect posting the finished findings to the PR in the launch dialog; --post requires Claude Code v2.1.227 or later. See Review a diff locally for the effort levels, targeting, and how it relates to /simplify. Alias: /review
Anthropic's notes
Upstream's own release notes for v2.1.311 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.
Fixed pasting text that mentions an image file, such as ! open /tmp/shot.png or /review look at /tmp/shot.png, attaching the image and dropping its path from the prompt
Fixed a finished /code-review , or another skill that runs in a sub-agent, running a second time when a cloud or background session restarts
Changed /code-review to tell Claude to put the effort level first and use max only when asked
The GitHub issue this fixes
A model matched these issues to Anthropic's notes, so a link can be wrong.

Hard to understand Too vague Looks wrong Not relevant to me Too long Missing the detail I wanted Duplicate of another card
