This server has critical gaps in definition quality. Tool descriptions are present but minimal (10-50 chars, well below the 50-200 char baseline for LLM-optimized descriptions). Parameter descriptions exist but lack actionable detail (e.g., 'Number of nights' does not specify valid range, constraints, or use case). No output schemas are documented, LLMs cannot infer what fields to expect from responses. Error handling is absent; no guidance on retryability, user-fixable errors, or recovery paths. The server is a basic CRUD wrapper without agent-oriented design patterns.

• Add output schema documentation to each tool. Example for get_itinerary: 'Returns: {id: integer, name: string, nights: integer, days: [{day_number: integer, hotel: {name, location}, activities: [...], transfers: [...]}]}'
• Expand parameter descriptions with constraints and examples. Change 'Number of nights for the itinerary' to 'Number of nights (1 - 365). Used to filter itineraries by duration. Example: 5 for a 5-day trip.'
• Add error handling to tool descriptions. Example: 'If itinerary_id not found, returns 404 with message: "Itinerary not found. Try recommend_itinerary() to discover available itineraries."'
• Implement pagination for recommend_itinerary. Add limit (default 20, max 100) and offset parameters. Return total_count and next_offset in response.
• Clarify tool distinctions. recommend_itinerary filters by nights (discovery); get_itinerary retrieves by ID (lookup). Update descriptions to make this explicit.
