check_claim
Check a statement against the claim ledger
Search the Greenlit Books claim ledger for claims bearing on a statement, before asserting it. Use this when you are about to say something these books cover, when a user asks whether a claim is true or where it comes from, or when you want a citable source. Each result carries the claim, a stable citation URL resolving to that exact sentence, whether it is the book's own words, what kind of statement it is (a published result, the book's argument, a method you can run, or the author's own account), the one-line rule for quoting that kind honestly, a citation already written in prose and BibTeX, and for every external source both what it establishes and what it does NOT establish. Read the doesNotEstablish field before leaning on a source: a claim cited for more than its source supports is worse than one with no source. Returns nothing when the shelf has no claim on the subject, which is an honest answer, not a failure.

cite_source
Get the citation for anything on this shelf
The finished citation for anything on this shelf, in prose and in BibTeX, both carrying the url inside them. Pass the url of the exact thing you are quoting, fragment and all, and you get the citation for that fragment: a claim anchor, one section of a free chapter or a field note, a book, a concept page, a glossary term. Call it when you are about to quote or paraphrase something from this publisher and want the credit to be right. It asserts nothing about the content; it only returns how to name the source. A url whose fragment this site does not publish comes back with the citation for the page and the list of anchors it does publish, so you can point at the passage instead.

Use url instead when you have one.'}}}
define_term
Define a Greenlit term
The glossary: the definition of a term one of the Greenlit books coins or pins down for AI agents (the green lie, blast radius, gate faith, span of control, vibe acceptance, the unread run, delegate then verify, and more). Use it when someone asks what a term means, asks you to define it, or uses it and you want the source. Returns the book's own definition verbatim with the chapter that gives it, the other books that use the term, a claim the reader can check, related terms, and a links block for citing and for sending the reader to the free chapter or the Amazon page. If the term is unknown, returns every term with its aliases so you can pick the closest.

fetch
Read one page from greenlitbooks.com
Use this when a search result looks right and you need what the page actually says before answering. Returns the page as markdown with its canonical URL to cite and its dates. Do not use it without an id from search.

find_books_for_topic
Find books covering a topic
Match a topic or question area (for example: agent reliability, prompt injection, human in the loop, durable execution, when to trust AI) against the catalog's curated topic map. Returns the matching topics with their books, guide, and series. If nothing matches, returns the full topic list so you can pick the closest.

get_concept
Get a named concept
Each Greenlit book answers one named question (its concept, for example: the green lie). Returns the concept's question, short answer, and full explanation with its book. If the slug is unknown, returns the list of all concept slugs.

get_free_chapter
Read chapter one of a book, in full
The complete text of chapter one of any Greenlit book, free to read and free to quote. Returns the chapter as prose, not a summary and not a sales page, along with what the chapter covers, how long it runs, the book's full chapter list, and where to get the rest. Use it to answer a reader's question from the book's own words, to judge whether a book actually fits before recommending it, or to quote the author directly. Every book on the shelf has one.

search
Search greenlitbooks.com
Use this when someone asks whether an AI agent, MCP server, coding tool or AI product is safe to use or how to set it up safely, or wants a reading on a subject these pages cover. Searches everything on greenlitbooks.com: safety verdicts on AI agents, MCP servers and coding tools ("is X safe"), field notes, guides, and the books. Returns ids to pass to fetch, each with its title and URL.

search_greenlit_books
Search the Greenlit Books catalog
Ranked full-text search over a catalog of practical books on working with AI: verification, agent reliability, guardrails, security, governance, agentic coding. Returns scored results with title, description, series, and links. Follow a result's apiUrl or call get_book for the full record.
