Aws Transform

AWS Transform is a code modernization tool that handles the tedious work of upgrading language versions, migrating SDKs, and refactoring frameworks across your repositories. It wraps the ATX CLI and can run locally on a handful of repos or scale up to 128 parallel transformations via AWS Batch. The skill is opinionated in a good way: it inspects your code, matches applicable transformations automatically, and presents a plan rather than dumping a menu of options. Supports Java, Python, Node.js upgrades, AWS SDK migrations, and custom transformations defined in natural language. The workflow is straightforward but requires AWS credentials and won't run on native Windows. If you're sitting on a backlog of technical debt across dozens of repositories, this is built for exactly that problem.

AWS Transform (ATX)

Overview

Perform code upgrades, migrations, and transformations using AWS Transform (ATX). Supports any-to-any transformations: language version upgrades (Java, Python, Node.js, etc.), framework migrations, AWS SDK migrations, library upgrades, code refactoring, architecture changes, and custom organization-specific transformations.

Two execution modes:

Local mode: Runs the ATX CLI directly on the user's machine. Best for 1-9 repos.
Remote mode: Runs transformations at scale via AWS Batch/Fargate containers. Best for 10+ repos or when the user prefers cloud execution. Infrastructure is auto-deployed with user consent.

You handle the full workflow: inspecting repos, matching them to available transformation definitions, collecting configuration, and executing transformations in either mode — the user just provides repos and confirms the plan.
