Claude Skills Guide

Claude Code Skills for Travel Booking Platforms

Travel booking platforms require complex integrations with multiple APIs, real-time data processing, and dynamic pricing logic. Claude Code skills provide an elegant way to encapsulate domain knowledge and automate repetitive workflows in travel applications. This guide walks through practical skill designs for common travel booking scenarios. Explore more domain-specific patterns in the use cases hub.

Core Architecture for Travel Skills

A travel booking skill needs clear boundaries between what Claude controls and what external systems handle. The skill orchestrates API calls, formats data for users, and maintains state across interactions. Your primary tools are Bash for executing scripts, Read for accessing configuration, and Write for generating outputs.

Structure your travel skill around three phases: initialization (loading API credentials and user preferences), execution (processing the booking logic), and cleanup (releasing resources and updating caches).

# flight-tracker.md
<!-- Store in ~/.claude/skills/flight-tracker.md -->

Monitor flight prices and alert on drops.

When the user asks to track a flight, extract the route and date, then check the price using the bash tool.

Flight Search Integration

Flight search requires coordinating multiple data sources. Build a skill that accepts departure city, destination, and date range, then queries your preferred APIs. The skill should normalize responses into a consistent format users understand.

#!/usr/bin/env python3
# flight_search.py - Simplified flight search handler
import sys
import json
from datetime import datetime, timedelta

def search_flights(origin, destination, departure_date, return_date=None):
    # Mock API response for demonstration
    flights = [
        {
            "airline": "SkyAir",
            "flight_number": "SA 234",
            "departure": f"{departure_date}T08:30:00",
            "arrival": f"{departure_date}T14:45:00",
            "price": 342.00,
            "currency": "USD"
        },
        {
            "airline": "Oceanic Airlines",
            "flight_number": "OA 891",
            "departure": f"{departure_date}T14:15:00",
            "arrival": f"{departure_date}T20:30:00",
            "price": 298.00,
            "currency": "USD"
        }
    ]
    return flights

if __name__ == "__main__":
    args = sys.argv[1:]
    results = search_flights(args[0], args[1], args[2])
    print(json.dumps(results, indent=2))

This script accepts three arguments: origin airport code, destination airport code, and departure date. Integrate it into your skill by calling bash with the appropriate parameters.

When the user requests flight search, extract:
- Origin airport (IATA code)
- Destination airport (IATA code)  
- Departure date in YYYY-MM-DD format
- Optional return date

Execute: python flight_search.py {origin} {destination} {departure_date}

Hotel Aggregation Patterns

Hotel booking involves aggregating data from multiple providers. Design your skill to fetch from several sources in parallel, then merge results by hotel property. This prevents single-source dependencies and gives users more options.

Your hotel search skill should:

1. Accept location (city name or airport code), check-in date, check-out date, and guest count
2. Query each configured provider API concurrently using background processes
3. Normalize responses into a standard schema:
   - hotel_name: string
   - location: string
   - price_per_night: number
   - rating: number (0-5)
   - amenities: array of strings
4. Sort results by price ascending by default
5. Present top 10 options with key differentiators highlighted

Handle edge cases gracefully: when a provider API fails, continue with available data rather than failing the entire request. Log the error for debugging but don’t interrupt the user experience.

Price Tracking and Alerts

Frequent travelers benefit from price monitoring. Build a skill that checks prices periodically and notifies users when fares drop. This requires persistent storage for user preferences and tracked routes — the supermemory skill provides a ready-made pattern for this persistent context.

# price_monitor.py - Track prices and detect drops
import json
import os
from datetime import datetime

PRICE_FILE = ".travel_prices.json"

def load_prices():
    if os.path.exists(PRICE_FILE):
        with open(PRICE_FILE, 'r') as f:
            return json.load(f)
    return {}

def save_prices(data):
    with open(PRICE_FILE, 'w') as f:
        json.dump(data, f, indent=2)

def check_price(route, current_price):
    prices = load_prices()
    route_key = f"{route['origin']}-{route['destination']}"
    
    if route_key in prices:
        historical = prices[route_key]
        lowest = historical['lowest_price']
        if current_price < lowest:
            return {
                'alert': True,
                'previous_low': lowest,
                'new_low': current_price,
                'savings': lowest - current_price
            }
    
    prices[route_key] = {
        'lowest_price': current_price,
        'last_checked': datetime.now().isoformat()
    }
    save_prices(prices)
    return {'alert': False}

This pattern extends to car rentals, vacation packages, and cruise bookings. The key is maintaining historical context to identify genuine deals versus normal market fluctuations.

Itinerary Management

After booking, travelers need to manage itineraries. Create a skill that stores trip details and provides contextual updates. This requires structured storage that persists across Claude sessions.

The itinerary skill manages:
- Active bookings (flights, hotels, activities)
- Trip timeline with dates and locations
- Document storage (confirmation numbers, voucher references)
- Weather alerts for destination dates

On invocation, display upcoming trips sorted by departure date.
Allow users to add, modify, or cancel bookings through natural language commands.

Integrate calendar APIs to automatically detect scheduling conflicts. When a user adds a flight, check against existing calendar events and warn about overlaps.

Best Practices for Travel Skills

Keep these principles in mind when building travel booking skills:

Secure credential handling — Never hardcode API keys in skill files. Use environment variables or a secrets manager. Your skill should fail gracefully if credentials are missing rather than exposing sensitive data.

Rate limiting respect — Travel APIs often impose rate limits. Implement request throttling and exponential backoff. Cache responses when freshness isn’t critical to reduce API calls.

Currency and locale awareness — Prices vary by user location. Store user preferences for currency (USD, EUR, GBP) and display format (1,234.56 vs 1.234,56). Use locale-aware date formatting.

Error transparency — When searches fail, explain why. “No flights found” differs from “API timeout” or “Invalid airport code.” Users can act on specific error messages.

Extending Your Skills

These foundational patterns scale into more sophisticated implementations. Add machine learning models to predict price trends, integrate loyalty program APIs for point redemptions, or build multi-city trip optimizers. Each extension follows the same architecture: clear input specification, reliable API orchestration, and structured output presentation. For complex booking pipelines that coordinate multiple skills, see how to combine two Claude skills in one workflow.

The travel booking domain benefits significantly from Claude’s ability to handle multi-step reasoning. Complex itineraries with dozens of segments become manageable when Claude can programmatically coordinate each step while maintaining coherent user communication.
