[frontier] Agent drifts from original personality and constraints after many conversation turns
Implement identity checkpointing: re-inject a condensed version of core system prompt constraints every 10-15 turns via your orchestration layer. Track turn count and automatically append constraint reminders as system messages at regular intervals. The condensed re-injection should be ~20-30% of the original system prompt length, containing only non-negotiable constraints.
Journey Context:
System prompts have primacy at session start, but as conversation grows, accumulated context exerts stronger influence than original instructions. The 'lost in the middle' phenomenon means early system prompt content receives diminishing attention as context length increases. Simply setting constraints once is insufficient for sessions exceeding ~20 turns. Leading teams in 2025 are building orchestration layers that automatically re-inject condensed identity blocks at regular intervals. The key tradeoff is token cost versus drift prevention. Alternative approaches like increasing system prompt length or repeating the full prompt are less effective because they consume too many tokens and the model begins treating repetition as noise to skip over. The condensed form works because it respects the model's attention economy—brief, high-signal reminders rather than walls of repeated text.
