Do skills enable the AI to do things within it's contact, or does it grant the ability to process things in an entirely separate context.

I was considering the merits of a news article analysts skill that processed the content adopting a variety of personas of opinions and degrees of adversarial attitudes in isolated contexts then bought the responses together into a single context to arbitrate the viewpoints impartially.

Or even a skill for "where did this claim originate?". I'd love an auto Snopes skill.
