Server has 5 tools with complete input schemas and descriptions. Naming follows verb_noun convention (search_*, get_*). Descriptions are present and contextual (avg ~120 chars), meeting baseline minimums. However, output schemas are not documented in the visible code, only inferred from Pydantic model validation. Parameter descriptions are adequate but lack constraint details (ranges, formats, enums). Error handling is minimal, no recovery guidance or categorization visible. No tool annotations (readOnlyHint, destructiveHint) despite all tools being read-only. Missing idempotency guarantees and rate-limit guidance.

• Document output schemas for all tools. Add a 'Returns' section to each tool description or expose schema definitions. Example: 'Returns FlightSearchResult with fields: flights (array of {airline, price, departure, arrival}), total_results (int), search_id (string).'
• Add readOnlyHint: true to all tool definitions. This signals to agents that these tools are safe to call speculatively without side effects.
• Convert parameter constraints to formal enums and min/max declarations. E.g., flight_type: enum ['1', '2'], adults: integer with minimum: 1, maximum: 9.
• Add error recovery guidance. E.g., get_weather description: 'If date > 16 days out, returns error field. Call get_historical_weather_average instead.' Implement structured error responses with actionable next steps.
• Implement pagination for search_flights, search_hotels, search_itinerary. Add limit (default 20, max 100) and offset/cursor parameters. Document result caps in descriptions.
