Agent Memory's Core Flaw: Notes Are Written Before Questions Exist

A technical analysis published on DEV Community argues that poor agent memory notes are not a matter of effort or prompt quality, but a structural design flaw. At the time a note is written, the future queries it must serve do not yet exist, making write-time precision fundamentally undefined rather than merely difficult. The piece draws on a 1960s information-science concept called anticipatory indexing, attributed to Robert Fairthorne, to show this problem predates AI agents. Unlike demand forecasting, note writing offers no recurring feedback signal against which a writer's output can be measured or improved. The author concludes that the solution is not a better writing process but a different unit of storage altogether.
