AI Agent Skills
Skills are folders of instructions, scripts, and resources that AI agents can discover and use to execute tasks with more precision and efficiency. Agents are increasingly capable, but often lack the context needed to work reliably. Skills solve this by giving agents access to procedural knowledge and company, team, and user-specific context, loaded on demand.
