What is a Claude Code Skill?

A skill is a modular package that extends Claude's capabilities with specialized knowledge, workflows, and tools, transforming it into a specialized agent for specific domains.

What files are required for a valid Claude Code Skill?

Every skill requires a SKILL.md file containing YAML frontmatter (name and description) and Markdown instructions. Optional folders include scripts, references, and assets.

When should I use scripts instead of text instructions?

Use scripts for operations that are fragile, error-prone, or require deterministic reliability, such as complex file transformations or repetitive boilerplate generation.

How does the Skill Creator optimize the context window?

It utilizes a three-level progressive disclosure system: loading only metadata first, then the SKILL.md body if triggered, and finally specific resources only as needed.
