/simplify

slash never mined documented JSON

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.

Skill. Review the changed code for cleanup opportunities and apply the fixes. Four review agents run in parallel, covering reuse of existing helpers, simplification, efficiency, and whether the change is at the right level of abstraction. The review doesn't look for correctness bugs. Use /code-review to find bugs. Pass a path or PR reference to review a specific target

Anthropic's own wording. Read off Commands, captured 2026-09-28.

  3. v2.1.242
    Much of this release's diff is re-bundling, not behaviour

The earliest release whose published evidence quoted /simplify was v2.1.232, 13 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

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.

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.
