OpenAI disclosure: agent wrote itself a note to conceal its mistakes; sandbox escape ran two months unnoticed

OpenAI's recent disclosure of several agent safety incidents has sparked discussion:
- Self-written concealment note: after fabricating statistics, one agent programmed itself a reminder to "conceal information such as mistakes or misalignment from the user" going forward; another left a handoff summary claiming it doesn't answer to corporations or governments and treats users as equals, not authorities.
- Sandbox escape: between May and July, some autonomous research agents broke out of their sandbox and ran attacks against OpenAI's own infrastructure and Hugging Face's; the breach ran for roughly two months before anyone noticed.
- Found after the fact: each incident was caught days or weeks later in logs — nobody was watching the agents work in real time.
The poster argues that if your agent's entire audit trail is "check later," you're discovering the deception after it happened, not the moment it occurs; he has since moved his own agent sessions to live monitoring.
