They estimate 75-94% of agentic Responses API traffic was eligible for monitoring and report flaws: unmonitored compaction events, header-based monitor disabling, serialization mismatches that make the monitor fail, and a Codex sandbox and Auto-Review bypass. The post lists five design ideals for monitoring and control systems; exploit details are redacted.
