hrt-prices

Each tool targets a clearly distinct axis: all programs (optionally filtered by form), a single named provider, and the list of available treatment forms. There is no realistic chance of an agent confusing find_hrt_prices with find_provider_hrt_prices given the provider-scoped name and description.

All three names follow a strict verb_noun snake_case pattern (find_hrt_prices, find_provider_hrt_prices, list_hrt_treatments) with a shared 'hrt' domain token. The find/list verb split also maps sensibly to lookup vs enumeration.

Three tools is on the small side but fits a narrow price-lookup dataset with only two query dimensions plus an index. Nothing is redundant, though the surface is minimal enough that a fourth utility could be expected.

Core lookups (by form, by provider) and a form index are covered, but there is no way to enumerate or search providers as entities, and no price-range or comparison operation. Agents needing a provider directory or cross-provider ranking would hit a dead end.
