Librarian Agents is designed to file documents before questions arrive

The article describes a research system that organizes documents into a navigable workspace, with links back to the originals, before an answering model gets a question. It reports 0.75 accuracy on BrowseComp-Plus with a Qwen3.5-4B answerer, versus 0.42 for an embedding-based retrieval baseline. The author also shares an untested home-build outline and warns that workspaces can go stale or lose rare details.
