Travel Planning Agent
A multi-agent travel planning system orchestrated with LangGraph, using tool calling and human-in-the-loop review.
Problem
Planning a trip end-to-end usually means juggling several disconnected tools and a lot of manual back-and-forth to research, compare and finalize an itinerary.
Solution
A multi-agent system built with LangGraph, where specialized agents collaborate to research and assemble a travel itinerary. Agents use tool calling to pull in external information, with a human-in-the-loop checkpoint so the user can review and adjust the plan before it's finalized.
Architecture
An orchestration graph coordinates specialized agents (e.g. research, itinerary planning) through LangGraph, with tool-calling nodes for external actions and an explicit human approval step in the loop.
Key Features
Multi-agent orchestration, LLM tool calling, human-in-the-loop approval before finalizing output, and a Python-based agent pipeline.
