How do I ensure my custom skill is formatted correctly?

Run the package_skill.py script, which automatically validates your YAML frontmatter, naming conventions, and directory structure before creating a distributable zip file.

When should I use scripts versus references in a skill?

Use scripts for deterministic code that Claude shouldn't have to rewrite from scratch, and use references for large documentation or schemas that should only be loaded when relevant.

What is the progressive disclosure design principle?

It is a three-level loading system where Claude only consumes metadata initially, then the SKILL.md body if triggered, and finally bundled resources as needed to save context space.

How do I start building a new skill?

Use the init_skill.py script provided in the repository to generate a standardized directory structure including the required SKILL.md file and resource folders.

What is a Claude Code Skill?

A skill is a modular, self-contained package that extends Claude's capabilities with specialized knowledge, workflows, and tool integrations, effectively acting as an onboarding guide for specific domains.

開発者ツール

Streamlines the development of custom Claude Code skills through automated scaffolding, validation, and standardized workflow guidance.

The Claude Skill Creator provides a comprehensive framework and toolset for building modular, self-contained packages that extend Claude's capabilities with specialized domain knowledge and custom workflows. It guides developers through a structured process—from initial conceptualization and planning to automated initialization and packaging—ensuring every skill follows the progressive disclosure design principle to maximize context window efficiency. By providing templates for bundled scripts, reference documentation, and static assets, it transforms Claude from a general-purpose assistant into a specialized agent equipped with procedural knowledge for complex, repetitive tasks.
