Report #26634
[frontier] Agent loses continuity of 'self' across long sessions, forgetting its assigned persona \(e.g., 'senior Rust engineer'\) while retaining general knowledge, leading to inconsistent code style and architecture decisions
Implement a 'persona core' memory tier: maintain an immutable 'identity vector' \(summary of role, constraints, style\) that is re-injected into the context window every 5 turns or when semantic drift is detected \(>0.3 embedding distance from baseline\); use structured storage \(e.g., SQLite\) for episodic memories but keep the persona in the active context layer; implement a 'persona validator' tool that checks proposed outputs against the core identity before execution
Journey Context:
Simple summarization destroys persona details. Vector DB retrieval often returns irrelevant technical facts instead of identity anchors. The MemGPT approach \(Berkeley 2023\) treats the persona as OS 'kernel' state that cannot be swapped out. Teams often try to 'fine-tune' the persona in, but that prevents runtime adaptation. The tradeoff is context space vs. consistency; the 0.3 threshold provides a tunable knob.
