[architecture] Agent saves useless conversational filler to long-term memory, bloating the vector store and degrading retrieval quality

Insert an LLM-as-a-judge evaluation step before writing to memory. Extract only discrete, atomic semantic or episodic facts from the conversation, and discard greetings, procedural acknowledgments, and instructions.

Journey Context:
Naive agents embed and store every user/assistant turn verbatim. This quickly fills the vector store with high-volume, low-signal noise \(e.g., 'OK', 'Sure, I can do that'\). When the agent searches later, semantic similarity returns these useless chunks, pushing out relevant facts. The tradeoff is an extra LLM call per write operation, increasing cost and latency. However, this curation step drastically improves retrieval precision and reduces storage costs, ensuring the memory remains a high-signal knowledge base rather than a raw log.
