What are the mandatory fields for a Claude Skill?

Every SKILL.md file must start with a YAML frontmatter block containing a 'name' (maximum 64 characters) and a 'description' (maximum 1024 characters).

What is the main purpose of the Skill Builder?

It provides a standardized framework and guide for creating custom capabilities for Claude, ensuring they are optimized for autonomous discovery and context efficiency.

How does progressive disclosure work in Claude Skills?

It is a tiered loading system where Claude only loads metadata (Level 1) initially, and only pulls in full documentation (Level 2) or reference files (Level 3) once the skill is actually triggered.

Where should I store my custom skills?

Personal skills should be placed in ~/.claude/skills/, while project-specific, version-controlled skills should be placed in the .claude/skills/ directory at your project root.
