# Library Hub: agent docs

> Keep your Calibre library as notes: covers, living shelves, a reading list, summaries, and metadata fixes you review before they reach Calibre. Uses Model Hub for models. These files are for coding agents building a plugin on its API (@insurgently/library-hub-api). They were built 2026-10-30. The installed package carries the same files for the version you have: prefer it to what you remember.

Read AGENTS.md first.
