Watch an agent catalog a book.
Four Claude Code skills run in sequence over a title, abstract, and table of contents — conceptual analysis, quantitative filtering under SHM H 180, validation against local Library of Congress authority indexes, and MARC 6XX synthesis under H 1075. Pick a book from the menu at the top right and watch that session replay, unedited, at reading speed.

About this demo
- Nothing runs here. This page replays a transcript captured from a real Claude Code session; it is a recording, not a live agent.
- Authority data is local. LCSH and LCGFT lookups hit a TF-IDF index built
from the LC MADS/RDF authority downloads, so validation works offline. Name headings query
id.loc.govdirectly. - No
