The authors formalize self-evolving agents as systems that update their harness (prompt, memory, skills) from task feedback while model weights remain frozen.
Self-evolving agents trade plasticity for stability in continual learning streams.
Evaluating three representative methods across drifting task streams reveals that self-modification and memory retrieval both accumulate interference over unseen and prior tasks.

The authors test whether nonparametric self-evolving LLM agents, which adapt by rewriting prompts, memory, or code without updating model weights, can function as continual learners.
