What is AI Agent Skills?
AI Agent Skills is a directory of reusable capabilities (skills) that act like plugins for AI agents. Each skill packages instructions, references, templates, scripts, and workflow guidance in the open Agent Skills standard. Users browse the catalog, copy a one-line installation command, and paste it into their agent environment to activate the skill on demand. The platform is community-driven, open-source, and not officially affiliated with Anthropic or OpenAI.
