Fresh Memory, Stale Plans: Dependency-Scoped Validation for Distributed LLM-Agent Memory

A study published on arXiv indicates that in distributed LLM agent teams, although members can access the latest shared facts, they may still act based on outdated plans. The study describes a scenario where the planner develops actions based on requirement r3, another agent submits requirement r4, but the executor does not replace the original plan when receiving r4, causing it to continue acting according to the old plan. This problem is referred to as “fresh memories, outdated plans” and is attributed to the lack of a dependency scope verification mechanism.
