Report #13010

[architecture] Agent memory grows infinitely until it degrades performance; how should I implement memory decay and curation?

Implement a scoring function combining Recency, Frequency, and Importance \(RFI\) to calculate a memory's retention score, and actively discard or archive memories falling below a threshold.

Journey Context:
Storing every interaction leads to retrieval noise and ballooning storage costs. Agents need a forgetting mechanism akin to human memory. Just using vector similarity is insufficient because a rare but highly important fact might be forgotten, while a frequent but trivial fact persists. The RFI score \(inspired by the Spacing Effect\) allows the agent to forget trivial daily logs but remember critical user preferences.
