TDQS
Scored across 5 tools
Each tool has a clear, distinct purpose: cart creation, item addition, cart viewing, product retrieval, and catalog search. No two tools overlap in functionality.
All tool names follow a consistent verb_noun pattern in snake_case (add_to_cart, create_cart, get_product, search, view_cart). The naming is predictable and easy for an agent to follow.
With exactly 5 tools, the surface is well-scoped for a storefront domain. Each tool serves a necessary function without redundancy or bloat.
Core cart and product operations are covered. However, missing cart update (quantity change), remove item, or checkout functionality leaves minor gaps that agents might need to work around.
