[frontier] Agent quality degrades significantly after N turns — should I restart the session?
Implement session segmentation: proactively break long sessions into managed segments, transferring a structured state object \(not raw conversation history\) between segments. Explicitly capture: \(1\) active constraints, \(2\) decisions made, \(3\) current task state, \(4\) identity markers. The break-even point is typically 20-40 turns depending on task complexity.
Journey Context:
Rather than letting a session degrade continuously, leading teams are implementing session segmentation — proactively ending a context window and starting a new one with a structured state transfer. The key is that the state transfer must be structured, not just a narrative summary. A naive summary loses the structural information that keeps the agent anchored and often omits constraints that the agent has already drifted away from. The structured state transfer acts as a 'fresh start' that re-anchors the agent without losing session continuity. The break-even point varies: simple Q&A tasks can go longer; complex multi-step tasks with many constraints degrade faster. The cost of the segmentation step \(one additional LLM call to generate the state object, plus the latency of starting a new context\) is consistently less than the cost of operating a degraded agent. LangGraph's state management pattern formalizes this approach with checkpointed state graphs.
