What files are mandatory for a new skill?

Every skill requires a SKILL.md file containing YAML frontmatter with 'name' and 'description' fields, plus the Markdown body instructions.

What is a Claude Code Skill?

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

Why is token efficiency important in skill creation?

Skills share the context window with the system prompt and conversation history; keeping skills concise ensures Claude has more room to process the actual user request.

What is the Progressive Disclosure design principle?

It is a strategy to manage context by loading information in stages: metadata first, then the SKILL.md body, and finally specific bundled resources only when needed.

When should I use scripts versus text instructions?

Use scripts in the /scripts folder for tasks requiring deterministic reliability or complex logic that would be token-expensive for Claude to rewrite repeatedly.
