[frontier] Agent gradually violates constraints with no internal mechanism to detect its own drift

Deploy a lightweight oversight agent with a short, constraint-fresh context that periodically reviews the primary agent's recent outputs against the original constraint set. The oversight agent must have no conversation history—only the constraint definitions and the output to evaluate. Use a smaller, cheaper model for the oversight role.

Journey Context:
Single-agent architectures have a fundamental blind spot: the agent cannot detect its own drift because the drift is gradual and the agent's self-evaluation is contaminated by the same context that caused the drift. You cannot ask a drifted agent whether it has drifted—it will evaluate itself against its drifted constraints, not the original ones. A separate oversight agent with a short, fresh context can objectively evaluate compliance because it isn't subject to the same context pressure. The oversight agent must be lightweight \(a smaller model is acceptable and preferred for cost\) and must never accumulate conversation history—each evaluation starts from a clean state. This pattern is emerging in production multi-agent systems in 2025-2026 as teams realize that self-evaluation is fundamentally insufficient for drift detection. Critical design consideration: the oversight agent must evaluate against the ORIGINAL constraint text, not a summary, to avoid compounding drift through summarization. Tradeoff: adds infrastructure complexity and per-evaluation cost, but catches drift that is structurally invisible to the primary agent.
