Does that even fit in the context? It seems like 30 papers worth of content would just overflow it.

For each paper, have your agent extract a three sentence description, create a description.md, then concat those with the paper names into an INDEX.md which it should consult to find appropriate papers. Also: have your agent tag papers, then autogenerate your tagged collection on the filesystem. Then you get nice things like https://github.com/ctoth/Qlatt/tree/master/papers/tagged

Then something in your {CLAUDE,AGENTS}.md that says: when working on something with relevant context supplied by papers, read the papers before doing the work. You can find all papers plus their descriptions in ./papers/INDEX.md and papers by tag in ./papers/tagged
