Report #96639
[architecture] Agent appends new facts to the vector store without deleting or updating contradictory old facts, causing it to retrieve both a prior state and a new state simultaneously, leading to confused outputs
Implement a memory consolidation or update mechanism. When inserting a new fact, search for semantically similar existing facts. If a contradiction is found \(via LLM judge\), either delete the old fact or update the existing vector payload, rather than blindly appending.
Journey Context:
Vector databases are typically append-only, which is great for logs but terrible for state. Human memory updates; if a user changes their preference, the old preference is overwritten. An agent that only appends will accumulate contradictory states. Implementing a read-before-write or consolidation step ensures the memory store reflects the current state of truth, not a history of all states.
