[frontier] Agent loses sense of self/identity after context window compression
Externalize constitutional identity using the Model Context Protocol \(MCP\)—store the agent's 'self' definition \(constraints, values, personality\) in MCP Resources and fetch it via tool calls every turn rather than storing it in the context window.
Journey Context:
Traditional agents store identity in the system prompt or context window, which inevitably gets summarized or compressed in long sessions, leading to personality drift or constraint amnesia. The Model Context Protocol allows agents to query external resources as if they were API endpoints. By moving the constitution from passive context \(which degrades\) to active retrieval \(fetched fresh each turn\), the agent's identity becomes independent of context length. This is the difference between 'remembering who you are' \(fallible\) and 'reading your identity card every morning' \(reliable\). The tradeoff is increased latency \(one extra tool call per turn\) and the risk of the retrieval failing \(requires fallback to cached identity\). However, for high-stakes long-session agents, the durability of externalized identity outweighs the latency cost.
