Report #1501

[architecture] Agent retrieves too much long-term memory into the context window, overwhelming the LLM and diluting the focus on the immediate task

Separate working memory \(current scratchpad/task context\) from long-term memory \(vector store\), and only inject long-term memories when working memory explicitly lacks required information.

Journey Context:
People think RAG solves context limits, but injecting top-k chunks blindly adds noise. LLMs suffer from 'lost in the middle' and distraction. Working memory is fast but volatile; long-term is slow but persistent. The tradeoff is latency vs. accuracy. If you stuff the prompt with 10 retrieved memories, the LLM loses track of the current step. Only retrieve long-term memory to fill specific gaps in working memory, and keep the working memory strictly focused on the current execution trajectory.
