What is a Claude Code Skill?

A skill is a specialized, modular package that extends Claude's capabilities by providing domain-specific knowledge, procedural workflows, and tool integrations.

When should I use a script instead of text instructions?

Use scripts for fragile, error-prone, or repetitive tasks that require deterministic reliability or where the AI would otherwise waste tokens rewriting code.

What files are required for a custom skill?

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

How does the Skill Creator optimize context window usage?

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

開発者ツール

Provides expert guidance and structured workflows for developing, optimizing, and packaging specialized Claude Code skills.

概要

The Skill Creator is a meta-utility designed to help developers build high-quality extensions for Claude Code by implementing core principles of modularity and context efficiency. It guides users through the creation of specialized agents equipped with procedural knowledge, scripts, and domain-specific references that a general-purpose model may lack. By emphasizing progressive disclosure and specific 'degrees of freedom,' this skill ensures that custom-built capabilities remain token-efficient while providing deterministic reliability for complex technical tasks.
