[frontier] Agent's self-critique calibration decays approving its own erroneous outputs after many turns
Implement a 'critic lottery': with 20% probability, summon a fresh 'critic' agent \(with no session history and a frozen 'constitution'\) to review the output; if the fresh critic disagrees with the internal critic, trigger a 'context purge' or session reset.
Journey Context:
Agents often use self-critique or a dedicated 'critic' sub-agent to check outputs. Over a long session, the critic becomes 'contaminated' by the same context that generated the errors—shared assumptions, accumulated shortcuts, or 'groupthink'. The critic's calibration decays; it starts approving errors because it 'remembers' making similar choices before. The 'critic lottery' ensures that some checks are 'pristine', coming from an agent with no memory of the session's drift. This provides a baseline to measure how much the internal critic has drifted. If the fresh critic disagrees with the internal one, the session context is likely poisoned and should be purged or compressed aggressively. This is similar to 'ground truth' audits in data pipelines. Trade-off: cost/latency of spawning fresh critics vs. accuracy and hallucination rate.
