Towards Healthy Evolution: Exploring the Role and Mechanisms of Human-Agent Interaction in Self-Evolving Systems
Dianxing Shi, Junqi He, Junhao Chen, Bowen Wang, Yuta Nakashima
Abstract
Self-evolving agents improve through continual self-play and self-generated learning signals, but autonomous evolution can also cause capability degradation and safety drift. Although human feedback has proven effective for static and post-trained agents, its role in self-evolving systems remains underexplored. We introduce Agent Norm Correction through Human-like Oversight and Review (ANCHOR), an LLM-based framework that simulates human supervision and delivers feedback at various phases of self-evolution. With ANCHOR, we evaluate two representative open-source self-evolving agent systems across coding, mathematical reasoning, and safety. Our results show that even limited supervision substantially mitigates safety degradation while preserving stable performance on core evolutionary objectives. Further analysis shows that supervision over the output verification phase is the most effective for intervention, whereas increasing supervision frequency yields diminishing returns. These findings provide empirical evidence and practical guidance for designing more stable, controllable, and human-aligned self-evolving agent systems.

(1 models)Scientific Impact Assessment: ANCHOR Framework for Human-Agent Interaction in Self-Evolving Systems
1. Core Contribution
The paper addresses a timely and important problem: self-evolving LLM agents (those that improve through self-play without human intervention) can experience safety drift, capability degradation, and reward hacking over continued training. The authors introduce ANCHOR (Agent Norm Correction through Human-like Oversight and Review), a framework that uses an LLM-based supervisor as a proxy for human oversight, injecting evaluative (non-oracle) feedback at five distinct phases of the self-evolution loop: task proposal, planning, thought, output, and execution result.
The key novelty is the systematic study of *where*, *how much*, and *how* supervisory feedback should be inserted into self-evolving training pipelines. The paper delivers three empirical findings: (1) even simulated supervision mitigates safety degradation while preserving task performance; (2) feedback on the execution/verification phase is most impactful; (3) supervision frequency exhibits diminishing returns, with low-to-moderate frequencies achieving near-maximal gains.
2. Methodological Rigor
The experimental design is reasonably comprehensive, covering two self-evolving frameworks (AZR and R-Zero), multiple backbone models (3B to 14B parameters), and three evaluation dimensions (coding, math reasoning, safety). The use of multiple safety benchmarks (HarmBench, SaladBench, HEx-PHI, and a custom Reward Hacking benchmark) strengthens the safety evaluation.
However, several methodological concerns arise:
3. Potential Impact
The paper addresses a genuine and growing concern as self-evolving agents become more prevalent. The practical finding that low-frequency supervision achieves near-maximal gains is valuable for real-world deployment, where human oversight is expensive. The framework's design — injecting feedback through system prompts rather than modifying the training algorithm — is elegantly non-invasive and could be adopted easily.
The Reward Hacking benchmark contribution (memory-induced reward hacking in service, medical, financial, and sales domains) is a useful secondary contribution, though it is only briefly described and would benefit from standalone validation.
The impact is somewhat constrained by the narrow scope of self-evolving paradigms tested (both are proposer-solver frameworks). Generalization to other self-evolution architectures (e.g., those based on different RL formulations, multi-agent debate, or tool-augmented evolution) remains unverified.
4. Timeliness & Relevance
This paper is highly timely. The rapid emergence of self-evolving agents (DeepSeek-R1, AZR, R-Zero, MM-Zero) has created a clear gap in understanding how to maintain safety during autonomous training. The paper correctly identifies that most existing human-agent interaction work focuses on inference-time or static training settings, not on the training loop itself. The June 2026 submission date aligns with a period of intense activity in this space.

Overall Assessment
This paper makes a solid empirical contribution to an important and timely problem. It provides useful practical guidance for practitioners building self-evolving systems. However, the novelty is more in the systematic experimental study than in the technical framework itself (which is essentially prompt-based LLM feedback). The paper would be strengthened by real human studies, stronger statistical analysis, and comparison with simpler safety-preserving baselines. The findings, while intuitive, are valuable as empirical confirmation.

While Paper 1 provides a strong methodological contribution to visual spatial planning for embodied AI, Paper 2's focus on the stability and safety of autonomous systems carries a wider potential impact for future AI development and deployment.
Paper 2 is more methodologically rigorous and broadly impactful: it introduces a formal measurement framework and metrics for appropriate reliance on set-valued AI advice across classification and regression, fitting widely used human-AI decision paradigms. This has clear real-world applicability (uncertainty communication, decision support, calibration) across many domains and can become a standard evaluation toolkit.

The reported jump on SWE-Bench Pro (59%→78%) suggests strong real-world utility and timeliness for agentic LLM improvement. Methodologically, it proposes a general loop (coreset selection, parallel rollouts, self-evaluation, pairwise self-preference) that can transfer across domains.
