The authors tested write-time compression in TextWorld cooking games, where an agent's writer repeatedly converts its previous state and latest observation into a state capped at 128 tokens.
Short agent memories fail mainly by dropping facts too early
Controlled text-game experiments separate unavoidable memory limits from poor write-time choices, then show a training method can modestly improve short-delay retention.

Shen and Li study agents that repeatedly rewrite a fixed-size state instead of retaining their full interaction history.
Why this paper
From Independent Researcher and Kean University
In one line
Fixed-size LLM agent memory fails mainly because writers discard future-relevant facts, and reader-loss training reduces this regret only over short delays.
