Scored across 16 tools
Each tool has a clearly distinct purpose with no significant overlap. For example, 'add_to_cart' and 'update_cart' handle different cart operations, while 'check_warehouse_stock' and 'get_delivery_options' address separate availability concerns. The descriptions reinforce these distinctions, making tool selection straightforward for an agent.
All tools follow a consistent verb_noun naming pattern, such as 'add_to_cart', 'get_product_details', and 'track_order'. This uniformity enhances readability and predictability across the set, with no deviations in style or convention.
With 16 tools, the server is well-scoped for a Costco e-commerce domain, covering authentication, product search, cart management, order processing, and membership functions. Each tool serves a specific role, avoiding bloat while providing comprehensive coverage for typical shopping workflows.
The toolset offers complete coverage for the Costco shopping domain, including CRUD operations for cart items, order lifecycle from checkout to tracking, product discovery, and account management. No obvious gaps exist; agents can perform end-to-end tasks like searching, adding to cart, checking out, and tracking orders seamlessly.
