[frontier] Need systematic protocol to maintain agent identity and constraints across sessions of 50\+ turns

Implement the Identity Checkpoint Protocol: \(1\) Create an identity digest: persona label \+ tone directive \+ top 3–5 constraints \+ output format, ≤200 tokens. \(2\) Inject this digest as a system-level message every N turns where N=10 for safety-critical constraints, N=15–20 for style/tone. \(3\) At each checkpoint, append a self-audit trigger: 'Before responding, verify your last 3 outputs aligned with these instructions. If any drifted, explicitly correct.' \(4\) Vary the digest wording slightly each injection to prevent the agent from learning to ignore repeated identical text.

Journey Context:
Production teams in 2025 are converging on identity checkpointing as the standard response to instruction drift, moving beyond static system prompts toward dynamic identity management. The key insight is that identity maintenance is a control systems problem requiring feedback loops, not a prompt engineering problem solvable with stronger initial conditions. The protocol treats the instruction set as a signal needing periodic amplification to overcome context noise. The digest must be condensed because re-injecting the full system prompt every N turns consumes too much context budget. The self-audit trigger creates a closed-loop feedback mechanism. The wording variation prevents 'banner blindness'—the well-documented phenomenon where agents stop attending to repeatedly identical text blocks, treating them as noise rather than signal. Teams implementing this protocol report 40–60% improvement in constraint adherence over sessions exceeding 30 turns.
