I would argue that recognizing if the agent is an adversary also requires breadth and a willingness to dive deep when you need to. Both things that the article highlights.

Before agents that is what every high performing person I've ever worked with was like. It was the kind of person I wanted to hire when I was in charge of that sort of thing. Enough breadth to know where to dive deep and enough willingness and curiosity to dive deep.

We’ve been trusting (or distrusting) our agents for all of recorded history. The choice between Claude or Codex matters. Trust matters.

this is true for humans too
