[frontier] Agent output drifts from original constraints over a long conversation even though the context window still has room

Treat drift as a bounded stochastic process, not unbounded decay. Re-inject a one-sentence goal reminder every 4–6 turns and keep the active constraint set small \(≤5 items\). This shifts the equilibrium downward without bloating context or forcing a session restart.

Journey Context:
Teams often fight drift by repeating the full system prompt every turn \(expensive and noisy\) or by giving up and restarting sessions. Multi-turn drift research shows outputs converge to a finite KL-divergence equilibrium: recent turns dominate attention, but the divergence stabilizes rather than growing forever. The right leverage is small periodic restoring forces, not massive context dumps. Common mistake: assuming that because the system prompt is still technically in context, it is still behaviorally salient.
