From Single Chatbot to a Stateful Multi‑Agent Travel Planner (Google ADK)

Most “travel chatbots” fail the same way: they forget constraints, return generic advice, and confidently invent details. Travel planning is a high‑variance task — it includes preferences, logistics, and time‑sensitive information — so a single prompt that tries to do everything becomes brittle.

This project demonstrates a better approach: build travel planning as a small workflow using Google’s Agent Development Kit (ADK). The system captures constraints, runs parallel research tasks, and synthesizes a plan from the collected artifacts — while persisting state across turns.
