[architecture] Agent saves every single thought and action to memory, making future retrieval noisy and expensive
Gate memory writes with a reflection or importance scoring step. Before persisting a memory, ask the LLM to score its importance \(1-10\) or classify if it is a transient thought vs. a durable fact. Only persist memories above a threshold.
Journey Context:
When agents are given a save\_memory tool, they often over-use it, treating it like a log file. This causes write amplification: the vector store fills up with 'I am now thinking about step 1', which are useless for future queries and dilute the embedding space. The tradeoff is the cost of the importance-scoring LLM call on every potential write. However, this cost is negligible compared to the long-term degradation in retrieval quality and the storage costs of an uncurated memory store.
