The Problem Has Moved From Prompt Hygiene to Access Architecture
The conversation about AI agent security has been dominated by the wrong question. For the last two years, most of the energy in this space has gone into making AI agents say the right things. Guardrails. Output filters. Prompt sanitization. The implicit assumption is that the risk lives at the language layer. That assumption is now definitively wrong. The problem has moved from prompt hygiene to access architecture. The risk is not what agents say. It is what they do - with authorized access, through legitimate tool calls, in ways that no output filter was designed to evaluate.
