Report #87155

[frontier] Agent that was working perfectly starts producing lower quality outputs as session approaches context limits

Implement proactive session segmentation: when context reaches 60-70% of window capacity, initiate a handoff protocol that creates a structured session summary, extracts active constraints and state, and spawns a fresh context with the identity block \+ session state \+ conversation summary

Journey Context:
Quality degradation near context limits isn't just about running out of tokens—it's about the attention dilution that happens as context fills. Even with 200K token windows, agents show measurable quality degradation at 60-70% capacity because the attention budget is spread too thin across too many competing signals. The frontier practice in 2025 is proactive session segmentation: deliberately ending a context and starting a new one before quality degrades, rather than after. The handoff protocol is critical—it must preserve: \(1\) identity block \(immutable\), \(2\) active task state \(what's being worked on\), \(3\) conversation summary \(what was discussed\), in that priority order. Teams that implement this report consistent quality across multi-hour sessions that previously degraded after 45-60 minutes.
