Scored across 16 tools
Each tool targets a distinct action (login, search, select, checkout, etc.) with clear boundaries. No two tools overlap in purpose.
All tool names follow a consistent verb_noun pattern using snake_case (e.g., search_hotels, get_hotel_details, cancel_reservation). Single-word tools like status and login fit the verb style.
16 tools cover a comprehensive hotel booking workflow from login to check-in and loyalty management. Slightly above the typical 3-15 range, but still well-scoped and each tool earns its place.
Covers authentication, search, details, room selection, extras, booking, modifications, cancellations, check-in, and loyalty. Minor gaps like viewing account profile, but core booking lifecycle is complete.
