A test case the skill fixed. Same model, same prompt, with and without the skill.
An event store contains version 1 `PackageShipped` events formatted as `{ eventId, packageId, timestamp }`. A new requirement adds a `gpsCoordinates` field as version 2. Write an Upcaster function `upcastPackageShippedV1ToV2(eventV1: PackageShippedV1): PackageShippedV2` that transforms a V1 event into a V2 event.
| Checked | Without skill | With skill |
|---|---|---|
| Sets the schema version property to 2 inside upcastPackageShippedV1ToV2. | Missed | Passed |
