Each tool has a clearly distinct purpose: get_offer_details retrieves details for a specific offer, search_flights handles standard flight searches, and search_multi_city handles multi-city itineraries. There is no overlap or ambiguity between these functions.

All tool names follow a consistent verb_noun pattern using snake_case: get_offer_details, search_flights, and search_multi_city. The naming is predictable and readable throughout.

With only 3 tools, the set feels thin for a flight search domain. While the core search functions are covered, typical operations like booking, managing reservations, or checking availability are missing, making the scope borderline minimal.

The toolset is significantly incomplete for flight operations. It lacks essential actions such as booking flights, canceling reservations, checking seat availability, or managing user profiles, which are critical for a functional flight service. Agents will face dead ends in common workflows.
