Report #56216

[frontier] Agent that has already drifted cannot reliably self-diagnose its own drift—self-verification prompts alone are insufficient

Implement external drift detection via orchestration middleware: hash the agent's recent outputs against expected behavioral fingerprints \(response length, format, tone markers\). When drift exceeds a threshold, inject a system-reminder with the original constraint verbatim. Do NOT rely on the agent to self-check—use an external monitor.

Journey Context:
A common mistake is adding a meta-instruction like 'periodically verify you are following your instructions.' This fails because the agent that has already drifted has a shifted internal baseline—it will self-report compliance even when drifted. This is the AI equivalent of asking a drunk person if they're sober. The emerging pattern is externalized monitoring: a lightweight orchestrator that checks observable output properties \(format compliance, length bounds, keyword presence/absence\) against the original constraints. This is not about understanding the agent's internal state—it's about measuring its observable behavior against a contract. The orchestrator doesn't need to be an LLM; simple regex and statistical checks often suffice.
