🎯 What are Skills?

Skills are Markdown files that teach Claude how to perform specific tasks. They are model-invoked: Claude automatically applies relevant Skills when your request matches a Skill's description, without requiring explicit invocation.

According to the Claude Code official documentation, Skills provide a powerful way to:

• Customize Claude's behavior to match your team standards
• Teach Claude to use specific tools and frameworks
• Automate common development workflows
• Share best practices across projects and teams
