"instructions": "Use the openlibrary_* tools to search books, editions, authors, and subjects via Open Library. No API key required. IDs are typed by suffix — works OL…W, editions OL…M, authors OL…A — and editions also resolve by ISBN. Canonical flow: openlibrary_search_books → openlibrary_get_work → openlibrary_get_editions/openlibrary_get_edition; for people, openlibrary_search_authors → openlibrary_get_author. The work tools take only work IDs (OL…W): from an ISBN, openlibrary_get_edition with id_type \"isbn\" returns the parent work_id. openlibrary_get_edition takes a batch of identifiers of one type in a single call. To find a book from a passage rather than its metadata, use openlibrary_search_inside — it searches the scanned text of Internet Archive books and usually takes 10–30 seconds, so reach for it deliberately. Resolve cover/photo IDs with openlibrary_get_cover_url — it always returns HTTP 200, so a missing image is a 1×1 placeholder GIF, not an error.",

"description": "Search the full text of books scanned by the Internet Archive — the \"which book contains this passage?\" lookup that the metadata tools cannot answer. Quote a phrase for an exact-phrase match; bare terms match anywhere in the text. Each result is an Internet Archive item with the matching passages as snippets, plus a relevance score. The full-text index is far slower than the metadata endpoints, and a search usually takes 10–30 seconds. Use it when the passage is the question, and use openlibrary_search_books to search by title, author, or subject. Results key on Internet Archive items rather than Open Library works: chain the returned ia_identifier to archive.org, or match it against the ia_identifiers on openlibrary_search_books results to reach the catalogue record.",
