What is a Claude Code Skill?

A skill is a specialized capability that enhances Claude's behavior by providing domain-specific guidance, best practices, and implementation patterns for specific tasks.

What is the difference between references and assets in a skill?

References are documentation or schemas intended to be read by Claude to inform its process, while assets are files (like logos or templates) meant to be included in the final output without being fully loaded into the context window.

Where should I store my custom skills?

Skills can be stored globally in ~/.claude/skills/ for personal use, or in a project's .claude/skills/ directory for project-specific automation.

What is the 'Progressive Disclosure' principle in skill design?

It is a three-level loading system (Metadata > SKILL.md body > Resources) that keeps the context window lean by only loading detailed information when Claude determines it is absolutely necessary.

How does Claude know when to trigger a specific skill?

Claude uses the 'description' field in the SKILL.md YAML frontmatter to decide when to load the skill automatically based on the user's request.
