I suspect this means a scanner that can derive all necessary information without any configuration. For example, consider a scanner looking for API endpoint authorization inconsistencies. Does the scanner need you to describe your authorization scheme, or can you simply run the thing and it figures it out?

This can be easy or hard depending on how bespoke your application is. If you're using something like Ruby on Rails, then there's a paved road that a scanner can preconfigure to understand your application. If you're using a homegrown authorization framework, then a scanner will likely have a hard time understanding your application and will need to be configured.
