  "account": "AI agents are not magic; they are workflows with probabilistic decision-making and real-world privileges. They follow a classical operator feedback loop of observe, decide, act, and repeat, with the deciding step being a language model. The good news is that twenty years of distributed-systems security apply almost unchanged, as everything around the language model can be secured. AI agents require secured for-loops, with identity issued per agent, short-lived and cryptographically verifiable, authorisation scoped per tool and enforced in the runtime, and deny-all as the starting posture with grants as deliberate exceptions. A signed execution history is also necessary to answer \"what did the agent do\" in an audit. While prompt injection against a legitimately granted tool remains a weakness, infrastructure can keep the set of things a misbehaving model can reach small, turning a catastrophe into an incident.",
  "summary": "If agents were magic, we couldn’t secure them. They aren’t, so we can. AI agents are not magic. They are workflows with probabilistic decision-making and real-world privileges. Strip away the framing and you find the classical operator feedback loop you already know from Kubernetes controllers and embedded thermostats: observe, decide, act, repeat. The only new element is that the deciding step…",
