# Agent-STAR TravelDataset
This repository contains the synthetic queries and datasets presented in the paper [Demystifying Reinforcement Learning for Long-Horizon Tool-Using Agents: A Comprehensive Recipe](https://huggingface.co/papers/2603.21972).
The dataset serves as a long-horizon tool-use testbed for Reinforcement Learning (RL) research, specifically utilizing the TravelPlanner environment.

## Dataset Description
The dataset includes over **17K** synthetic queries generated through a three-step pipeline: element sampling, feasibility checking, and LLM back-translation. These queries require agents to iteratively call tools to satisfy multifaceted constraints.
