Report #61492
[frontier] Agent personality and instruction interpretation drift as context window fills, causing inconsistent tool use patterns and decision frameworks
Use Model Context Protocol \(MCP\) to maintain persistent identity metadata \(personality parameters, decision heuristics, constraint priorities\) outside the LLM context window, fetching relevant identity fragments on-demand
Journey Context:
Traditional approaches embed personality in system prompts, which suffer from positional bias and attention dilution. As context grows, early tokens \(including personality definitions\) receive exponentially less attention. The MCP pattern externalizes identity into structured resources \(similar to a separate process memory\) that the agent can query via tools. This creates 'identity persistence' regardless of context window state. The frontier implementation uses MCP servers to host vectorized personality embeddings, allowing the agent to perform semantic similarity searches against its 'core identity' before high-stakes decisions, effectively anchoring behavior against drift.
