Paper: EvoUndo Framework Ensures Recoverability in LLM Agent Self-Evolution

LLM agents increasingly modify their own prompts, tools, middleware, and execution harnesses at runtime. While such self-evolution can improve capability, a successful mutation may leave persistent effects that cannot be safely reversed in different states.
The paper introduces EvoUndo, a framework for representing, synthesizing, diagnosing, and verifying the recoverability of model-generated self-modifications across counterfactual states. Across 600 unseen tasks, 197 capability-improving mutations failed recoverability verification. Conventional repair strategies failed under original representations.
Deterministic oracle analysis shows that extending the recovery calculus improves oracle recovery rates significantly. The results indicate that reliable agent self-evolution requires co-designing verification, state grounding, witness semantics, and recovery-language expressivity, rather than relying on iterative prompting alone.
