Why the Execution Process Is More Dangerous Than the Final Answer: Evaluating AI Agent Harness Safety with HarnessAudit

The article argues that the real safety risks of AI agents lie in their execution harness rather than the model’s final output, and introduces HarnessAudit—a framework that audits full execution trajectories across eight real‑world domains, assessing boundary compliance, execution fidelity, and stability under perturbations.
