One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
We have private documents on AWS S3 that need presigned download URLs with query parameters (`querystring_auth = True`). We want to route those presigned URLs through a CloudFront custom domain using `AWS_S3_CUSTOM_DOMAIN = 'cdn.example.com'`. Show how to set up this custom storage class.
