I used to think the scary part of AI agents was the model hallucinating.
It isn’t.
The scary part is when your system looks fine — green logs, clean outputs, a polite writer agent producing a report — and somewhere in the middle, one message quietly changed the mission.
Not because a user typed something evil.
Because a researcher agent fetched a page. Because a tool returned poisoned text. Because the next agent trusted its teammate the way we trust people we work with every day.
