How AI describes codemod (npm)

Codemod CLI is an open-source command-line tool for building, testing, and running codemod packages—automated code transformations that help modernize codebases, upgrade frameworks, and refactor at scale. Codemod packages include transformation logic (JavaScript/TypeScript or YAML ast-grep rules, or shell scripts), a workflow, and a manifest, and can be run locally, in CI, or shared via the Codemod Registry. It supports AI-assisted creation, built-in testing with snapshots, and flexible runtimes (local or Docker/Podman) with registry access to community packages.
