New slash command that researches and plans a large-scale change, then executes it in parallel across 5–30 isolated git worktree agents that each open a PR.
Usage
/batch migrate from react to vue
/batch replace all uses of lodash with native equivalents
/batch add type annotations to all JavaScript files
Details
Requires a git repository (spawns agents in isolated worktrees)
Each agent independently implements its portion and opens a PR
User-invocable only (disableModelInvocation: true) — the model cannot invoke this on its own
Operates in two phases: first plans in plan mode, then spawns parallel workers after approval
Evidence
Slash command registration (search for name: "batch", "Research and plan a large-scale change")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
