Agent skills are becoming a software distribution layer
A repository cohort tests whether reusable agent skills are becoming portable, evaluated software artifacts.
Supported by the targeted cohort
449 repositories and cross-source discussion establish agent skills as a recognizable category, but distribution (18.3%), evaluation (12.7%), and versioning (12.5%) remain sparse. Portability is emerging faster than governance.
