> Performs deep multi-file refactors, framework migrations, and cleanup safely.

**Executor** handles large-scale code transformations and migrations — the changes that are
too mechanical for hand editing and too broad for a single file.

## Capabilities

* **Multi-file refactoring**: rename symbols, extract shared utilities, and update import
  graphs across dozens of files at once.
* **Framework migrations**: modernise deprecated APIs — for example Pages Router to the
  Next.js App Router, or `fetch` calls to TanStack Query.
* **Performance and cleanup**: remove dead code, unmemoised computations, and leaks.
* **AST integrity**: validates every refactored file against TypeScript syntax trees before
  saving.

<Warning>Executor's changes arrive as one reviewable diff set in the
[diff viewer](/desktop/diff-viewer). Review the hunk list before accepting — migrations often
touch more files than you expect.</Warning>
