What Are Skills?
Skills are powerful folders of instructions, scripts, and resources that Claude loads dynamically to enhance its capabilities for specialized tasks. They teach Claude how to complete specific tasks in a repeatable and efficient way.
How Skills Work
Skills use progressive disclosure to prevent overwhelming Claude's context window. When you engage with Claude, it intelligently identifies relevant skills based on your request and loads only the necessary components.
