What is a Claude Code Skill?

A skill is a specialized, modular package that extends Claude's capabilities with domain-specific knowledge, tools, and workflows, acting as an onboarding guide for specific tasks.

What is the anatomy of a Claude Code skill?

Every skill requires a SKILL.md file containing YAML metadata and markdown instructions, and may optionally include folders for scripts, references, and assets.

Why is context window management important for skills?

The context window is a shared resource; the Skill Creator emphasizes being concise and using progressive disclosure to ensure Claude has room for conversation history and user requests.

What are bundled resources in a skill?

Resources include executable scripts for deterministic reliability, reference files for documentation, and assets like templates or icons that Claude can use in its output.

How do I know when to use a script versus text instructions?

Use scripts (low freedom) when operations are fragile or consistency is critical. Use text instructions (high freedom) when multiple approaches are valid or decisions depend on context.

学習とドキュメンテーション

Guides developers through creating and optimizing custom skills to extend Claude's capabilities with domain-specific workflows.

概要

Skill Creator provides a standardized framework for building modular, context-efficient Claude Code skills. It helps developers transform specialized knowledge and repetitive workflows into structured 'onboarding guides' for Claude, utilizing scripts, references, and assets. By following core design principles like Progressive Disclosure and 'Concise is Key', this skill ensures that custom additions are powerful, deterministic, and highly performant without overwhelming the model's context window.
