List every book in the library, with its id, slug, name, author, type, and page count.

Return one book's chapter/section outline -- the map for get_section.

Lists every chapter (chapter_index, title, page_start) and, nested under each, its sections (section_index, title, page_start, approx_tokens). Auto-split sections have no native title; one is synthesized from a text snippet so it's still identifiable. Returns no section text -- that's get_section's job; this is just the map.

Typical flow: list_books -> get_book_outline(book_id) -> get_section( book_id, chapter_index, section_index) for targeted reading. Use search_book instead when you don't already know which section to read.

Search the library and return cited, scored excerpts.

Combines semantic and keyword search by default. Optionally scope to one book (book_id), or filter by exact author or source_type (one of "pdf", "epub", "markdown", "text").

Fetch one section's full text and summary.

The parent of a search_book hit, or a section located via get_book_outline's chapter_index/section_index map.

Report ingest status (chapter/section counts, chunk counts per stage) for every book.
