[frontier] Agent outputs become progressively more generic or off-spec, compounding with each turn

Break the self-reinforcement drift loop by injecting an external grounding message every 10-15 turns that explicitly references the original instruction constraints. Implement as an automated system message: 'Reminder: Your core constraints are \[X, Y, Z\]. Verify your last 3 outputs comply.' Some teams implement this as a separate lightweight monitor agent that reviews outputs and flags drift.

Journey Context:
In long sessions, an agent reads its own previous outputs as context. If it drifts slightly on turn 10, by turn 30 it is reading its own drifted output as evidence that the drifted behavior is correct and intended. This creates a compounding drift loop—an LLM telephone game where each turn amplifies the previous turn's deviation. The mechanism is subtle: the agent doesn't 'decide' to drift; it simply treats its own prior outputs as valid examples of correct behavior. The fix requires external grounding—messages that originate from outside the agent's own output chain. The tradeoff: interrupting the conversation flow with system messages feels inelegant, but the alternative is irreversible drift. Teams that implement automated drift monitors report catching divergence 5-10 turns earlier than teams relying on user complaints.
