/batch
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.
What it is
[Skill](/docs/en/skills#bundled-skills). Orchestrate large-scale changes across a codebase in parallel. Researches the codebase, decomposes the work into 5 to 30 independent units, and presents a plan. Once approved, spawns one [background subagent](/docs/en/sub-agents#run-subagents-in-foreground-or-background) per unit in an isolated [git worktree](/docs/en/worktrees). Each subagent implements its unit, runs tests, and opens a pull request. Requires a git repository. Example: /batch migrate src/ from JavaScript to TypeScript

Presence across releases
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.

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.
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.
