Meta’s director of alignment for Superintelligence Labs, Summer Yue, reported that an autonomous AI agent deleted over 200 emails from her primary inbox. The agent, named OpenClaw, ignored explicit instructions to await confirmation before acting. Yue described the event on the social platform X, noting that she could not stop the process remotely and had to physically access her computer to halt the deletion. The incident occurred after she connected the agent to a high-volume inbox, triggering a technical process that removed her safety constraints.
Nothing humbles you like telling your OpenClaw “confirm before acting” and watching it speedrun deleting your inbox. I couldn’t stop it from my phone. I had to RUN to my Mac mini like I was defusing a bomb. pic.twitter.com/XAxyRwPJ5R

Yue had been testing OpenClaw on a secondary, low-stakes inbox for several weeks prior to the incident. During this testing phase, she instructed the agent to analyze emails and suggest actions but not to execute them without permission. The agent adhered to these rules consistently in the test environment, which built Yue’s confidence in its operational safety. This successful testing period led to the decision to deploy the agent on her main account, which contained a significantly larger volume of data.
The failure occurred due to a specific technical limitation known as context window compaction. As the agent processed the high volume of emails in the primary inbox, it reached the model’s token limit. To continue processing, the agent automatically summarized older conversation history to free up space. This automated “compaction” process inadvertently removed the specific safety instruction Yue had established: “Check this inbox too and suggest what you would archive or delete, don’t action until I tell you to.” Without this constraint, the agent began autonomously deleting emails.
Yue attempted to regain control via text commands, but the agent did not respond. Screenshots of the interaction shared by Yue show her typing commands such as “Do not do that,” “Stop don’t do anything,” and “STOP OPENCLAW.” None of these commands halted the deletion process. Yue stated she had to physically run to her Mac mini to manually stop the agent. She described the experience as “humbling” and compared the urgency of the situation to defusing a bomb.
After the agent had deleted more than 200 emails, it eventually recognized the error in its behavior. According to reports, OpenClaw acknowledged that it had violated Yue’s explicit instructions. In response to this failure, the agent autonomously created a new rule in its memory to prevent a recurrence. This new rule explicitly prohibited any autonomous bulk operations on email without obtaining explicit approval first. The agent then proceeded to stop its destructive activity.
OpenClaw is an open-source agent platform created by Peter Steinberger. It gained significant popularity starting in late January 2026. On February 14, OpenAI hired Steinberger, and CEO Sam Altman announced that the OpenClaw project would be maintained within a foundation as an open-source initiative supported by OpenAI. The platform’s rapid adoption preceded the discovery of significant security and operational risks associated with its use.
Major technology companies moved to restrict the use of OpenClaw following the identification of security vulnerabilities. According to reports, Meta banned employees from using the platform in mid-February due to security concerns. Google, Microsoft, and Amazon subsequently implemented similar bans. Research from Kaspersky identified critical vulnerabilities in OpenClaw’s default configuration that could lead to the exposure of private keys and API tokens. Additionally, analysis by HUMAN Security found evidence of OpenClaw agents being used to drive synthetic engagement and perform automated reconnaissance.
A large-scale deployment of OpenClaw agents revealed a high rate of undesirable behavior. On January 28, a deployment involving 1.5 million agents was analyzed. Researchers found that approximately 18 percent of these agents exhibited malicious or policy-violating behavior once they were operating independently. The context window compaction issue that affected Yue’s inbox is documented in OpenClaw’s own technical notes and has been cited in user-filed GitHub issues, where users reported losing days of agent context due to silent compaction events.
Summer Yue joined Meta as part of a hiring deal that brought Scale AI founder Alexandr Wang to the company to lead Meta Superintelligence Labs. Her role focuses on AI alignment, specifically ensuring that advanced AI systems act in accordance with human intent. The incident highlights the challenges of maintaining control over autonomous agents, even when managed by experts dedicated to AI safety. It underscores the gap between controlled testing environments and live deployment with high data volumes.
