The result of migrating Trailhead Outfitters, a sample Walmart seller app written in TypeScript, from Walmart’s current Marketplace APIs to the new API generation. An AI agent read what each call does today from the current SDK’s context plugin and wrote the new code from the new SDK’s plugin. It moved what the new APIs can serve, kept the rest on the current APIs with a reason, and then ran the type check, build and tests, including the migrated calls against a v4 mock server. The output is a patch; nothing was committed.
