EP228: Do Self-Evolving Agents Forget

Title: Do Self-Evolving Agents Forget? Capability Degradation and Preservation in Lifelong LLM Agent AdaptationSource: http://arxiv.org/abs/2605.09315v1Summary:This paper introduces the 'capability erosion' framework to quantify how autonomous self-evolution can degrade an agent's prior knowledge across workflows and models. It proposes Capability-Preserving Evolution (CPE) as a necessary architectural constraint for building stable, lifelong learning agents that can adapt to new tasks without catastrophic forgetting.
