Skill Creator

This is the meta-skill for building skills themselves. It walks you through the structure of SKILL.md files, the progressive disclosure pattern (metadata loads first, body loads when triggered, bundled resources load as needed), and how to balance specificity with context efficiency. The core insight is useful: treat Claude like it's already smart and only add what it genuinely can't infer. Includes practical guidance on when to use scripts versus references versus assets, and emphasizes keeping the main file under 500 lines by splitting content into reference docs. If you're publishing skills or building internal tooling that extends Claude, this codifies the design patterns worth following.

About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

What Skills Provide

Specialized workflows - Multi-step procedures for specific domains
Tool integrations - Instructions for working with specific file formats or APIs
Domain expertise - Company-specific knowledge, schemas, business logic
Bundled resources - Scripts, references, and assets for complex and repetitive tasks

Core Principles

Concise is Key

The context window is a public good. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual user request.
