AI agent skill registries provide curated libraries, marketplaces, and management platforms for modular capabilities and specialized instructions that expand autonomous agents. They are designed for AI engineers, developers, and operators looking to equip digital workers and coding assistants with domain-specific abilities. Unlike general prompt directories or full agent builders, these registries focus specifically on packaging reusable, executable skill extensions for existing agent runtimes.
