Agent Memory Should Have an Expiration Date: A Six-Field Metadata Framework
Hairy-Difficulty-411 · reddit · 2026-09-29
The author argues agent memory is usually discussed as a capability, but it should also be treated as stored data with a lifecycle.
They propose recording six fields per memory: where it came from, why it was saved, which user/org owns it, which tasks may use it, when it expires, and what must delete or replace it. Without this, an agent may confidently reuse outdated or misattributed information.
Key point: more memory isn't automatically better — it can just be a larger pile of old assumptions. Useful memory should be reviewable, correctable, and removable; sensitive info shouldn't become permanent just because it appeared once. The author asks how others handle memory expiration today.
