Use Codemod CLI whenever the user wants to migrate, upgrade, update, or refactor a codebase in a repeatable way. This includes framework migrations, library upgrades, version bump migrations, API surface changes, deprecations, and large-scale mechanical edits. First search the Codemod Registry for an existing package, prefer deterministic codemods before open-ended AI rewrites, run dry-runs before apply, and create a codemod package only when no suitable package exists.
