What is a Claude Code Skill?

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

Are the name and description fields mandatory in SKILL.md?

Yes, every SKILL.md must start with YAML frontmatter containing 'name' (max 64 chars) and 'description' (max 1024 chars) for Claude to discover the skill.

What is the benefit of progressive disclosure in skills?

It allows Claude to manage hundreds of skills by only loading metadata initially, loading full instructions and referenced files only when a specific skill is triggered.

Where should I store my custom skills?

Personal skills should be stored in ~/.claude/skills/ for global access, while project-specific skills belong in the .claude/skills/ directory within your project root.
