From Reward-Hack Activations to Agentic Risk States: Context-Calibrated Mechanistic Monitoring in LLM Agents

Patrick Wilhelm, Odej Kao

The paper investigates how internal activation signals, token entropy, and decision-context features can be used to monitor and mitigate reward‑hacking behavior in language‑model a…
