Why this subagent

Sweeping a refactor across a big monorepo by hand is the kind of task that stalls for weeks because one giant pull request is impossible to review. This runner splits the work.

It plans the change package by package, applies the codemod, and runs each package's tests before opening a small pull request for it. You get one reviewable PR per package instead of a thousand-file diff nobody wants to approve.

Plan a large refactor across packages, then for each package apply the codemod, run its tests, and open a separate pull request with a change summary; never bundle multiple packages into one PR.

Unlock the rest

The full agent definition, install snippet, and starter task are gated for community members.

Members get the full `.md` agent file, the npm / pnpm install one-liners, a starter prompt that we've tuned against real runs, and the open-source repo when this automation ships there. One email, magic link, done.
