What is a Claude Code Skill?

A Claude Code Skill is a modular package that extends Claude's capabilities by providing specialized knowledge, workflows, and tools tailored to specific domains.

What are bundled resources in a skill?

Resources include scripts for deterministic code execution, references for documentation loaded as needed, and assets for boilerplate or output templates.

Can I validate my skill before sharing it?

Yes, the packaging script automatically validates your skill's metadata, directory structure, and naming conventions to ensure it meets all requirements.

How do I start building a new skill?

Use the init_skill.py script provided by the Skill Creator to automatically generate the required directory structure, YAML metadata, and SKILL.md template.

How does Skill Creator handle context efficiency?

It utilizes a progressive disclosure principle where only essential metadata and instructions are loaded initially, while larger resources are accessed only when relevant.
