TDQS
Scored across 6 tools
Tools have distinct purposes, but find_best_deals and find_cheapest_offers could be confused initially; descriptions help differentiate them.
All tool names follow a consistent verb_noun pattern in snake_case, e.g., compare_prices, list_sources.
6 tools is well-scoped for a shopping deals server, covering search, comparison, details, and sources without being excessive.
Covers key operations like search, price comparison, and best deals, but lacks filtering or wishlist features, which are minor gaps for this domain.
