Scored across 3 tools
Each tool has a distinct purpose: finding airports, exploring cheapest dates, and searching specific flights. No overlap.
All tool names follow a verb_noun pattern with consistent verb choices (find/search), making them predictable.
With only 3 tools, it's slightly minimal but covers the core flight search workflow without unnecessary bloat.
The tool set covers the full flight search lifecycle: locate airports, find optimal dates, and retrieve specific flights. No obvious gaps.
