What's in your RAG?

I want to up my game, with RAG. I tested it ages ago, but haven't found a usecase. I play with coding, projects, and light sysadmin work. # Thoughts RFC library - seems verbose unnecessary industry standards - typically in the model better than my cherry picked documents Codebase - I don't have the largest code base (fits in context) and it changes too often to index? Entire API references - this might work for small scripting
