MUSE-Autoskill: Self-Evolving Agents via Skill Creation, Memory, Management, and Evaluation
MUSE-Autoskill introduces a lifecycle-driven framework for LLM agents to autonomously build, organize, and refine reusable skills rather than treating them as static components. The system combines skill creation on demand with memory management, runtime evaluation, and continuous refinement, addressing a core bottleneck in agent scalability: how to move beyond hand-crafted skill libraries toward self-improving capability stacks. This matters because agent reliability and generalization depend heavily on skill quality and reuse patterns, making automated skill evolution a key lever for moving agents from narrow task solvers to adaptive systems.
Modelwire context
ExplainerThe paper's most underappreciated contribution is the evaluation loop: skills are not just created and stored but continuously scored and pruned at runtime, which means the agent can deprecate bad skills rather than accumulating a growing library of unreliable ones. That self-pruning property is what separates this from earlier tool-augmented agent work.
This is largely disconnected from recent activity in our archive, as Modelwire has no prior coverage to anchor it to. It belongs to a cluster of research exploring how agents manage persistent, reusable knowledge across tasks, a problem that sits adjacent to memory architecture work (retrieval-augmented generation, episodic memory stores) and to the broader question of how agents generalize without human-curated scaffolding. The skill lifecycle framing is a relatively recent lens on that problem, and this paper is an early entry in what will likely become a crowded sub-field.
The real test is whether MUSE-Autoskill's skill quality holds up on long-horizon benchmarks with distribution shift between training and evaluation tasks. If an independent replication on something like GAIA or AgentBench shows skill reuse rates above 40 percent on novel task categories, the lifecycle approach has legs; if reuse collapses on out-of-distribution tasks, the framework is solving a memorization problem, not a generalization one.
