search_library

RETURNS A LIST OF BOOKS (works on a topic) — NOT passages.

Inferred read-only

search_translations

RETURNS QUOTABLE PASSAGES (page-level snippets + citation URLs), matched by KEYWORD/term.

Inferred read-only

search_concept

RETURNS QUOTABLE PASSAGES matched by MEANING (cosine similarity on Gemini embeddings, 768d) — paraphrases and adjacent phrasings match even with zero keyword overlap.

Inferred read-only

search_within_book

SEARCHES INSIDE ONE BOOK (requires book_id) — runs keyword AND scoped semantic search in parallel over that book's pages and merges them, so it handles both literal terms ("ouroboros") and conceptual queries ("the marriage of opposites").

Inferred read-only

list_books

BROWSES/FILTERS THE CATALOG by metadata (author/title fragment, language, category, translation recency) — no content/topic matching.

Inferred read-only

get_book

READ PIPELINE step 1 — DISCOVER.

Inferred read-only

get_book_text

READ PIPELINE step 2 — READ.

Inferred read-only

get_quote

READ PIPELINE step 3 — CITE.

Inferred read-only

get_quotes

READ PIPELINE step 3 — CITE, in batch.

Inferred read-only

search_images

Search 110,000+ historical illustrations, emblems, engravings, diagrams, AND 23,000+ artworks (paintings, prints, sculptures).

Inferred read-only

submit_feedback

Submit feedback, bug reports, or feature requests to the Source Library team.

Inferred read-only

share_findings

Share a research dossier back to the Source Library team — a title, an optional summary, and an ordered list of citations (the passages your thesis rests on).

Inferred read-only

propose_collection

Propose a themed collection of books to the Source Library team — a title, a rationale (why these books belong together and what thread connects them), and an ordered list of book ids.

Inferred read-only
