MUSE-Autoskill: Self-Evolving Agents via Skill Creation, Memory, Management, and Evaluation

arXiv:2605. 27366v2 Announce Type: replace Abstract: Large language model (LLM) agents rely on reusable skills to solve complex tasks, but existing skill creation approaches often treat skills as isolated, static artifacts, limiting reusability, reliability, and long-term improvement.

MemSkill: Learning and Evolving Memory Skills for Self-Evolving Agents

MemSkill redefines memory operations in large language model agents as learnable and evolvable skills, enabling agents to extract, consolidate, and prune information from interaction traces more flexibly. It uses a controller to select relevant skills, an LLM-based executor to generate skill-guided memories, and a designer that reviews failures to refine or add new skills, forming a closed‑loop improvement cycle. Experiments on datasets such as LoCoMo, LongMemEval, HotpotQA, and ALFWorld show that MemSkill outperforms strong baselines and generalizes across settings, while analyses reveal how skills evolve over time.

WikiSkill: Compiling Agent Experience into Persistent Knowledge for Skill Evolution

WikiSkill is a framework that separates raw execution experience, accumulated knowledge, and executable skills, continuously consolidating experience into a persistent knowledge base (wiki). By co‑evolving agent skills with this wiki, the method consistently outperforms state‑of‑the‑art skill‑evolution techniques across diverse benchmarks and models. The study shows that larger models benefit more from evolved skills, smaller models can outperform larger ones when equipped with skills, and that skills transfer effectively across model families, with the wiki’s persistent knowledge being critical for success.

A Framework for Evaluating Agentic Skills at Scale

arXiv:2606. 17819v1 Announce Type: cross Abstract: Agent skills -- structured, reusable knowledge artifacts that augment LLM agent capabilities -- have been rapidly adopted in industry, yet their cross-domain impact and use across commercial and open-source models remain under-studied, and no reusable methodology exists for evaluating an individual skill.

When Not to Imitate: Boundary-Aware Skill Memory for Reliable Tool-Use LLM Agents

The paper introduces Boundary-Aware Skill Memory (BASM), a method that enriches skill memories for large language model agents with explicit boundary fields such as applicability conditions, risk cues, avoidance rules, and recovery notes. This approach transforms retrieved skills from unconditional templates into state‑conditioned guidance, preventing the Skill Imitation Trap where more skills lead to incorrect tool usage. Experiments on three agent benchmarks and four model scales show that BASM improves task success rates, accuracy, and reduces attack success while cutting average steps compared to memory‑free baselines.
