About
VR.dev is an open-source verification layer for AI agents, designed to ensure their actions align with expected outcomes and prevent reward hacking. It offers three tiers of verification: HARD (deterministic state checks against databases, APIs, and file systems), SOFT (LLM-based rubric scoring), and AGENTIC (agent-driven probing for complex workflows). The platform allows users to compose these checks into trust pipelines for continuous integration, evaluation, and reinforcement learning training. It provides ground-truth reward signals for training models like TRL, VERL, or OpenClaw, and generates structured evidence records with audit trails. VR.dev integrates with popular agent frameworks like LangChain and LangGraph, and can be run locally for free or via a hosted API for advanced features like evidence anchoring and team dashboards.
