[frontier] Earlier instructions become unreliable as the conversation lengthens; even frontier models drop adherence after ~18-20 turns

Re-state active constraints immediately before the current turn, avoid sharding critical instructions across many early turns, and design workflows to reset or hand off before the reliable turn budget is exhausted. Treat long instruction history as background, not authority

Journey Context:
Recent work shows instruction-following degrades monotonically with turn count, and even strong models sustain only about 18 reliable conversational turns. Distance to relevant content matters more than raw context length. Production teams in 2026 are moving from one long conversation to a chain of bounded sub-sessions with explicit handoffs, each anchored by a fresh, compact instruction set
