What is a Claude Code Skill?

A skill is a modular, self-contained package that extends Claude's capabilities with specialized knowledge, procedural workflows, and tool integrations.

What files are required for a custom skill?

Every skill requires a SKILL.md file containing YAML frontmatter metadata and markdown instructions. Optional directories include scripts/, references/, and assets/.

When should I use a script instead of instructions?

Use scripts for tasks requiring deterministic reliability, repetitive code generation, or complex operations where the same code would otherwise be rewritten multiple times.

How does Skill Creator optimize the context window?

It uses a three-level progressive disclosure system: metadata is always loaded, the skill body loads upon trigger, and detailed resources are only loaded as needed.

开发者工具

Guides the development of modular, context-efficient Claude Code skills using standardized frameworks and best practices.

The Skill Creator skill is a specialized meta-utility designed to help developers build and optimize custom capabilities for Claude. It enforces the 'Progressive Disclosure' design principle, ensuring that specialized knowledge, workflows, and tool integrations remain token-efficient. By providing a structured anatomy for skills—including scripts for deterministic tasks, references for domain expertise, and assets for boilerplate—it enables the creation of high-performance AI agents tailored to specific business logic or technical domains.
