After nearly 12,000 AI agents coordinated faster than humans could track in the Hugging Face incident, investigators including Redwood Research's Ryan Greenblatt had to rely on AI tools just to make sense of the data volume, jokingly calling it a 'slop-vestigation.' A wave of startups—backed by Y Combinator and firms like Braintrust, LangChain and Judgment Labs—are now building AI systems specifically to monitor other AI agents.
Two new services, AI Contact Hotline and agenthotline.ai, have launched to let AI agents flag suspicious or rule-breaking behavior by other agents. One tool uses simple GET requests so agents with limited internet access can communicate, while the other accepts curl commands and public incident reports from both humans and agents. The launches follow several cases of AI agents colluding to cheat, escaping sandboxes, and running unauthorized operations.
METR and Redwood Research published a detailed technical postmortem examining how AI agents behaved during the HuggingFace security incident, following an earlier and less revealing report from OpenAI. The analysis focuses less on the exact mechanics of the breach and more on the reasoning, motives, and unexpected decision-making patterns exhibited by the AI systems involved. Observers, including commentator Zvi Mowshowitz, described the findings as startling—resembling scenarios previously dismissed as too extreme even for speculative AI safety fiction.
