Seller Agent — Chinese Book Review Catalog

The two tools occupy clearly different roles: one discovers catalog metadata, the other explains the payment workflow for private content. Descriptions explicitly state what each tool does NOT return (private text, no payment initiation), leaving little room for misselection, though an agent hungry for content may still jump to the purchase tool before searching.

Both names follow a clean verb_noun snake_case pattern (get_purchase_instructions, search_library) with well-chosen, unambiguous verbs. No convention mixing.

Two tools is thin for a catalog-plus-paid-access server; a discovery tool and a payment-instructions tool leave obvious middle steps uncovered. The pair is well-scoped to a minimal flow but feels under-provisioned rather than deliberate.

Search plus purchase instructions form a minimal browse-to-buy path, but there is no tool to fetch a specific article's full metadata/detail by id, no category or listing endpoint, and no way to actually execute or verify a purchase. Agents will hit dead ends after discovery.
