Scored across 4 tools
Each tool has a clearly distinct purpose: listing states, searching facilities, getting facility details, and explaining treatment types. No overlap in functionality.
All tool names follow a consistent verb_noun pattern using snake_case (e.g., list_states, search_facilities).
Four tools is ideal for a directory finder: coverage discovery, search, detail, and terminology help. Each tool earns its place.
The set covers the full workflow: discover coverage (list_states), search with filters (search_facilities), retrieve full profile (get_facility_detail), and understand program types (get_treatment_types). No obvious gaps.
