About this paper

Yinghan Hou, Zongyou Yang

SkillSieve screens agent-skill packages before installation using cheap static checks, then applies contextual analysis and a three-model jury to packages that remain high-risk. On a human-reviewed benchmark of 390 skills, its full pipeline achieved F1 0.929, with precision 0.912 and recall 0.945. These results apply to that benchmark, not the 49,592-skill archive.
