/review
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.
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 own wording. Read off Commands, captured 2026-09-28.

First cited
0No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.
Presence across releases
0The 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.
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.
