## Description

Verifiers is a reinforcement learning environment framework and evaluation toolkit designed to train and evaluate large language models. It provides a standardized system for constructing simulation environments, managing training harnesses, and tracking agent trajectories through multi-turn interactions.

The project features a dedicated agent trajectory manager to handle branching rollouts and token sequences, alongside an evaluation toolkit that tests model outputs against defined reward rubrics and datasets. It includes capabilities for reward engineering and the ability to package environment modules for distributed sharing and remote execution.

The framework covers a broad range of operational areas, including automated metric collection, ablation-driven performance analysis, and the integration of model harnesses with reinforcement learning workflows to optimize agent behavior.
