I’d rather say you can use skills to do RAG by supplying the right tools in the skill (“here’s how you query our database”).

Calling the skill system itself RAG is a bit of a stretch IMO, unless you end up with so many skills that their summaries can’t fit in the context and you have to search through them instead. ;)

All skills are RAG, a subset of skills can add more RAG.
