> In most agentic prompt injection attacks, the agent treats the wrong content as a trusted source of instructions and allows itself to be misdirected or misused. This happens when the system fails to maintain a strict trust boundary between system-level directives and untrusted user data.

How on earth is a probabilistic token predictor supposed to turn untrusted user input into trusted system-level directives? The strict trust boundary must be maintained on this side of the agent, not within it.
