Creating Claude Code Skills

Complete guide for creating skills that extend Claude Code with your team's expertise and workflows.

What are Claude Skills?

Skills are folders of instructions, scripts, and resources that Claude can discover and load dynamically to perform specialized tasks. They follow Anthropic's progressive disclosure architecture for efficient, context-aware loading.

Key Concepts

• Filesystem-based: Skills are folders, not databases
• Progressive disclosure: Load information only when needed (3-level architecture)
• Auto-discovery: Claude finds and loads relevant skills automatically
• Portable: Skills work across projects and teams
• Composable: Agents can reference multiple skills
