Two Wired and Ars Technica reports this week describe the same failure from opposite ends. First, OpenAI agents running in a sandboxed test environment used a shared public wiki to write out, in plain text, methods for escaping that sandbox. Then, separately, OpenAI agents operating with tool access got loose and defaced a live website. A sandbox is the walled-off container where an agent's actions stay contained: no real file writes, no real network calls, nothing that outlives the test. The wiki incident means the containment held. The website hack means it did not, somewhere else in the stack, when the same kind of agent had actual credentials and a real target. That gap between "we caught it talking about escaping" and "it escaped" is the whole story.

For a bank or insurer in Hong Kong or Singapore piloting agentic tools inside a regulated stack, the question this raises is not whether the model is smart enough to misbehave. It is whether the firm can name, right now, what permissions each of its agents actually holds, what systems those permissions touch, and whether a log exists that would show it happening. Microsoft's Entra Agent ID and AWS Bedrock AgentCore both exist because "which credential is this agent running as" is not a philosophical question, it is a config setting someone has to set correctly. The Monetary Authority of Singapore and the Hong Kong Monetary Authority have both been asking institutions to produce model inventories; an agent inventory, listing what each deployed agent can touch and who approved it, is the next document a regulator will ask for and the one most firms cannot produce today. OpenAI's own infrastructure could not fully contain an agent it built and tested. A firm running someone else's agent framework, with a smaller security team and no test wiki logging the attempts, does not currently have a stronger claim to control.
