SkillFlow:Benchmarking Lifelong Skill Discovery and Evolution for Autonomous Agents

arXiv:2604.17308v1 Announce Type: new Abstract: As the capability frontier of autonomous agents continues to expand, they are increasingly able to complete specialized tasks through plug-and-play external skills. Yet current benchmarks mostly test whether models can use provided skills, leaving open whether they can discover skills from experience, repair them after failure, and maintain a coherent library over time. We introduce SkillFlow, a benchmark of 166 tasks across 20 families in which ta
