Scored across 7 tools
Each tool targets a distinct query type: keyword search, lowest-price summary, per-shop offers, price trend, shop list, site stats, and full product list. Minor overlap exists between search_products and list_all_products, and between get_lowest_price and get_offers (summary vs. detail), but the descriptions make the boundaries clear enough.
All names are snake_case verb_noun and follow a predictable pattern: search_/get_/list_ prefixes mapping cleanly to search, single-resource retrieval, and collection listing. No camelCase or inconsistent verb styles.
Seven tools is well-scoped for a price-comparison service covering search, per-product pricing, offers, trends, shops, and site metadata. Every tool earns its place with no filler.
The surface covers the core comparison lifecycle: find products, find prices, see offers, check trends, browse shops, and get site stats. Gaps are minor—no per-shop detail page tool and no way to browse the mentioned Telegram Bots, but agents can work around these.
