[architecture] Agent saves every single conversational turn to long-term memory, overwhelming the vector store and degrading retrieval precision

Implement an importance scoring step before writing to long-term memory. Have the LLM score the potential memory on a scale of 1-10 based on how critical, surprising, or actionable the information is. Only persist memories that exceed a threshold \(e.g., score > 7\). Discard or summarize low-importance turns.

Journey Context:
When building agents with persistent memory, developers often wire the memory save function to every LLM output. This creates a massive vector store full of 'Hello', 'Thanks', and trivial confirmations. When the agent searches this bloated store, the signal-to-noise ratio plummets, and retrieval latency increases. The tradeoff is that an LLM call to score importance adds latency and cost to every turn, and there is a risk of accidentally discarding a seemingly trivial fact that becomes important later. However, this is strictly better than the alternative: a degenerated, unusable memory index that returns garbage.
