What is a Claude Code Skill?

A Claude Code Skill is a specialized capability defined in a SKILL.md file that provides domain-specific guidance, patterns, and instructions for Claude to follow during tasks.

Why is progressive disclosure important for skills?

It allows Claude to manage hundreds of skills by loading only metadata initially; detailed instructions are only added to the context when the specific skill is triggered.

Where should I save my custom Claude skills?

Personal skills should be placed in ~/.claude/skills/[skill-name]/, while project-specific skills go in the root .claude/skills/[skill-name]/ directory.

What are the required fields for a new skill?

Every skill requires a YAML frontmatter at the top of the SKILL.md file containing a 'name' (max 64 characters) and a 'description' (max 1024 characters).

Can Claude skills run executable scripts?

Yes, you can include a scripts directory within your skill folder and reference those scripts in your SKILL.md for Claude to execute autonomously.
