Report #54624

[frontier] How do you test agent robustness against context window pollution and distraction attacks without production failures?

Implement adversarial context poisoning in CI/CD: automatically inject semantic noise, irrelevant distractor documents, and conflicting instructions into test context windows to measure agent consistency, hallucination rates, and instruction hierarchy adherence under pollution.

Journey Context:
Agents that perform well on clean benchmarks fail in production when context windows contain distractor documents \(in RAG\) or conflicting system prompts. Traditional unit testing uses clean inputs. Emerging 'chaos engineering' for agents involves 'context poisoning'—deliberately injecting high-entropy noise, semantically similar but wrong documents, and 'prompt injection' attempts during testing. This measures the agent's 'contextual discernment' \(ability to ignore noise\) and 'instruction hierarchy adherence' \(following system prompt over user injection\). This prevents the 'clean room' fallacy where agents work in testing but fail on messy real-world context. The pattern uses automated red-teaming pipelines that perturb context embeddings and measure output drift. This is distinct from simple fuzzing—it targets the specific failure mode of attention distraction in transformers.
