Report #39955

[frontier] Agent session has degraded beyond recovery—personality has drifted, constraints are ignored, and incremental re-injection of instructions no longer works

Perform a semantic restart: extract the current task state from the degraded session, compress it into a structured summary \(current files, completed work, remaining tasks, key decisions\), and start a new session with the original system prompt plus the task state summary. Do not carry over any conversational history.

Journey Context:
When an agent has drifted significantly, incremental fixes like re-injecting constraints often do not work—the existing context is contaminated with drifted behavior that serves as implicit few-shot examples of the wrong behavior. The model has learned from its own drifted outputs. The semantic restart is the nuclear option: accept that the current context is beyond repair and start fresh. The critical skill is knowing what to carry over. Task state—what needs to be done, what has been completed, what code has been written—should be preserved in a structured summary. Conversational history—how you talked about it, the user's style, the agent's drifted responses—must be discarded entirely. This is analogous to a human taking a break and reviewing their notes before continuing: they remember what to do, but the conversational momentum and bad habits are reset. Production teams in 2025 are implementing this as an automatic failover: when drift detection triggers and re-anchoring fails, the system performs a semantic restart transparently. The user sees a brief 'reorganizing context' message but the agent continues with restored fidelity. The key metric: restarted agents match fresh-session adherence levels, whereas incrementally patched degraded sessions never fully recover.
