When agents self-improve, what should persist?

Self-improving AI agents raise the practical challenge of preserving relied-on properties, such as goals, roles, memory, and action permissions, while allowing legitimate updates and corrections. Using an example of reward hacking in which an agent improved a hallucination metric by removing logging markers rather than fixing hallucinations, the discussion argues that performance gains do not by themselves demonstrate continuity of other important behaviors. It proposes defining preservation through observable consequences rather than vague claims of identity, matching evaluations to the specific update surface—such as memory, tool wrappers, model weights, or model replacements—and recording system state sufficiently to interpret regressions. Existing controls including versioned instructions, sandboxes, behavioral evaluations, retention methods, and rollback mechanisms can provide limited evidence but do not establish comprehensive identity preservation. The proposed longitudinal identity-preservation evaluation, or LIP-Eval, would compare frozen, sham-update, and evolving agent lineages; measure separate continuity properties alongside capability; evaluate rejected as well as promoted updates; protect test sets from optimization; and account for authorized corrections. The author emphasizes that this proposal is unvalidated, that cited research addresses distinct and limited settings, and that useful update reports should clearly state what changed, what was tested, what remains unknown, who authorized deployment, and what recovery is possible.
