🔬Agent-ToM: Catching Bad Agents with Theory-of-Mind Probes

TL;DR

New arXiv paper trains a learned monitor to flag autonomous LLM agents going off the rails by modeling their beliefs and intents, not just their outputs. Beats output-only baselines on a security-analysis benchmark.

Agent-ToM: Catching Bad Agents with Theory-of-Mind Probes — daily-hour-news

Key Points

1

Frames agent monitoring as a Theory-of-Mind problem: infer the agent's belief state, not just classify the next action

2

Targets the same problem Anthropic, OpenAI, and Google all flag as the biggest blocker to long-horizon agents

3

Reports gains over output-only and trace-only baselines on a security analysis benchmark

4

Public arXiv preprint with code references for reproducibility

Why It Matters

Output-classifier guardrails miss the agent that's about to make a fine action for a bad reason. ToM-style monitors are the direction enterprise agent platforms are heading.
