Summary
A new arXiv paper titled "When the Critic Falls Behind: Co-Evolving Rubrics and Harnesses for Continual Agent Self-Improvement" addresses how autonomous agents are improved. The snippet notes that agents increasingly rely on harnesses that govern interaction, memory, tools, and execution around large language models. It says recent work has begun evolving these harnesses from execution experience, but the supervision guiding that evolution often stays relatively static. According to the snippet, this makes it hard to track changing behavioral weaknesses across rounds and may limit generalization to unseen tasks.

What happened
Autonomous agents increasingly depend on harnesses that govern interaction, memory, tools, and execution around large language models (LLMs). While recent work has begun to evolve these harnesses from execution experience, the supervision used to guide evolution often remains relatively static, making it difficult...
Why it matters
Builders working on autonomous agents may care because the paper frames the supervision signal, not only the harness, as something that needs to keep changing during self-improvement. Teams that rely on fixed evaluation criteria could see weaknesses go untracked as an agent evolves. The snippet is cut off and describes the problem only, so the proposed method and its results are not visible here.
