A3.7/5.0

Scored across 5 tools

Disambiguation4/5

Each tool has a distinct retrieval axis: codes for one store (find_promo_codes), newest codes across stores (latest_promo_codes), store discovery (search_stores), and category enumeration (list_categories). The only mild overlap is between find_promo_codes and search_stores, since both can answer 'what's available for store X' and search_stores surfaces a 'best offer', but the descriptions clarify when to prefer each.

Naming Consistency4/5

All names are snake_case and resource-oriented, with four following a verb_noun shape (find_, list_, report_, search_). latest_promo_codes breaks the verb-first pattern by using an adjective, which is a minor deviation but still immediately readable and unambiguous.

Tool Count5/5

Five tools is well-matched to a narrow coupon-lookup domain, with no redundant or filler endpoints. Discovery, retrieval, browsing, and feedback each have exactly one tool.

Completeness4/5

The surface covers the full shopper loop: find codes, browse stores, see newest offers, explore categories, and report outcomes that feed the vote tally. A minor gap exists around fetching a single store's full profile or filtering codes by condition/expiry, but agents can work around this via search_stores and find_promo_codes.

Inputs: store (required).
