Reliable reinforcement learning (RL) agents must maintain operational integrity amidst sensor malfunctions, dynamic disturbances, and slow environmental shifts. The detection of out-of-distribution conditions is pivotal to determining when an agent's observations, transitions, or trajectory dynamics deviate from the assumptions underpinning its policy training.

MAADBench is a refreshable benchmark for anomaly detection in multi‑agent systems powered by large language models. It addresses the challenge of keeping benchmarks current by sampling and coupling generative tasks, generating trace data under configurable LLM backbones, and automatically providing deterministic step‑level labels. The authors evaluated 25 anomaly‑detection methods on 5,200 labeled traces, finding that existing approaches depend heavily on supervision, struggle with subtle MAS‑specific anomalies, and lack robustness across different LLM backbones.

The paper introduces Patterns of Past Rewards (PPR), a lightweight, algorithm‑agnostic online change‑point detector for cooperative multi‑agent reinforcement learning. PPR smooths agents’ return streams, highlights recent changes, and applies a statistical drift detector to flag significant shifts. Experiments in a custom Speaker‑Listener environment show that PPR balances detection speed and alarm stability, outperforming both a smoothed‑return baseline and a raw‑return detector.
