SkillAlchemy: Open-World Agent Skill Creation
Quick summary
arXiv:2608.23417v1 Announce Type: new Abstract: Agent skills are reusable procedural artifacts that extend language agents with specialized workflows, tool conventions, and domain behaviors at inference time. However, creating reliable skills still depends largely on human authorship, model priors, or execution traces. These sources are often unavailable for unfamiliar tasks, suggesting the need to create skills from open-world materials. In this paper, we study open-world skill creation: given an underspecified skill brief and a source-access specification, a creator must discover behavior-re

Why it matters
The significance goes beyond a temporary access problem: “SkillAlchemy: Open-World Agent Skill Creation” exposes the operational cost of depending on one AI provider. Critical tasks need predefined fallback, queueing and human-continuation paths.
