Report #75798

[architecture] Agent memory database grows indefinitely, leading to retrieval noise, increased storage costs, and the agent recalling irrelevant past events

Implement memory consolidation and decay: periodically summarize older episodic memories into higher-level semantic insights \(e.g., 'User prefers dark mode' instead of 5 instances of 'User clicked dark mode'\) and delete the raw episodic traces.

Journey Context:
Agents that log every interaction verbatim create a noisy retrieval environment. When querying, the top-K results get polluted with redundant, low-level logs. Human memory naturally consolidates. Mimicking this by summarizing/decaying old memories keeps the vector store dense with high-signal insights and reduces retrieval noise. The tradeoff is the loss of granular auditability and the compute cost of running background consolidation tasks, but it is necessary for long-running agents.
