How do I know my whole app is Rails Asset Pipeline Compliant?

I am trying to figure out where my issue is for when I try to use aws cloudfront to render the rails assets. Not sure if there is a tool that will determine if my whole app is rails asset pipeline compliant (whether it meets its standards, etc). Any help would be appreciated, even helping me figure out how do I know for sure that my assets are coming from CloudFront and not from my app.
