The exercise is not fully realistic because I think getting hundreds of suspicious emails puts the agent in alert. But the "no reply without human approval" part I think it is realistic because that's how most openclaw assistants will run.
Point taken. I was mistakenly assuming a conversational agent experience.
I love the idea of showing how easy prompt injection or data exfiltration could be in a safe environment for the user and will definitely keep an eye out on any good "game" demonstration.
