US return policies, price-match rules, discounts, deals and Amazon price verdicts. Read-only.
Scored across 23 tools
The set follows a clean search/detail pattern per content domain (search_deals→get_deal, search_return_policies→get_return_policy, search_birthday_freebies→get_birthday_freebie), making most selections obvious. The residual overlaps are mild: get_store_credit_cards vs search_credit_cards (retailer-scoped vs database browse) and get_store_deals vs search_deals both return per-retailer deal lists, which could tempt a wrong pick. The retired predict_amazon_price is clearly flagged as a no-op, so it does not create confusion.
Overwhelmingly consistent snake_case with predictable verbs — search_*, get_*, compare_* — and parallel singular/plural pairs (get_birthday_freebie / search_birthday_freebies). Minor deviations are about_thrifle (verbless) and who_will_price_match (question phrasing rather than verb_noun), plus the stale predict_amazon_price referencing a product the server no longer supports.
23 tools is on the heavy end of the range, though the breadth is largely earned by covering nine distinct content domains (deals, returns, price matching, cards, discounts, birthday freebies, blog, cancellations, macro data). One slot is wasted on predict_amazon_price, a permanently retired stub, and get_deal_of_the_day is a thin singleton that could fold into search_deals; trimming those would bring the set into a comfortable range.
Core workflows are covered end-to-end with browse→detail pairs and cross-links (e.g. get_credit_card linking to the partner retailer's return policy, who_will_price_match as the reverse of get_price_match_policy). The notable gap is cancellation guides: get_cancellation_guide has no search/browse companion and admits coverage is small, so an agent cannot discover which merchants are supported. Macro data and blog content are also read-only by nature, which is appropriate.

Inputs: merchant (required), product.
The store and co-branded credit cards a US retailer offers, with APR, annual fee, whether promotional financing is deferred interest, and links to each card's full terms, the retailer's store-card page and its return policy.
