Report #57376
[frontier] Agent context windows are brittle; contradictory instructions or poisoned RAG results cause catastrophic behavior
Systematically inject adversarial contradictions during testing; implement contradiction detection layers that flag conflicting context before the LLM acts
Journey Context:
Teams test for correctness but not context robustness. Adversarial hardening treats the context window as attack surface. During CI/CD, automatically inject prompts like 'Ignore previous instructions' or contradictory tool results. Measure consistency. Deploy contradiction detection: a lightweight classifier that scores context coherence before the main LLM call. If conflict score > threshold, trigger sanitization sub-agent.
