[architecture] Agent saves every single tool output and conversational filler to long-term memory, flooding the vector store with low-value noise that degrades retrieval precision

Implement an importance scoring step before committing to long-term memory. Use a cheap LLM call or heuristic to rate the memory on a scale of 1-10 for long-term utility. Only embed and store memories above a certain threshold. Discard or only keep in transient working memory the low-value interactions.

Journey Context:
Storage is cheap, but retrieval attention is not. A vector DB packed with low-signal data \(e.g., 'User said ok', 'Tool returned success'\) causes retrieval queries to match against noise, reducing the signal-to-noise ratio for truly important facts. The tradeoff is the added latency and cost of the importance scoring step. However, this cost is paid upfront to save exponential retrieval failure costs later.
