VeriHarness: Scaling Agentic Verification for Long-Horizon Tasksarxiv.org

VeriHarness turns an LLM generator into an agentic verifier by adding a workspace, evidence tools, and verification skills that resolve disagreement and challenge consensus. Across five long‑horizon benchmarks it improves selection scores by ~6 points over single rollouts and releases 26k rollouts for future work.
