Report #27198

[frontier] Agent loses context across sessions; naive database queries break tool-calling flow

Expose vector stores and key-value memory as MCP Resources \(resource://memory/\{id\}\) not just Tools, letting agents fetch state via URI subscription without function-call latency

Journey Context:
Teams initially bolt memory onto Tools \(search\_memory tool\), but this forces LLM to generate JSON for every recall, adding 500ms\+ latency and token cost. MCP Resources allow the host to inject context directly into the prompt via resource subscriptions, zero latency. Tradeoff: Resource schema must be static, so use resource templates for dynamic access. Alternative is tool-calling for everything, which scales poorly for high-frequency memory access.
