EP228: Why self-evolving AI forgets basic tasks

Title: Do Self-Evolving Agents Forget? Capability Degradation and Preservation in Lifelong LLM Agent Adaptation

Source: http://arxiv.org/abs/2605.09315v1

Summary:

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.
