Skill Creator

If you're building skills for Claude, this is your starting point. It walks through the core principles: keep things concise since context window is shared, match specificity to how fragile the task is, and use progressive disclosure so Claude only loads what it needs when it needs it. The structure is clear: required SKILL.md with frontmatter and instructions, optional scripts for deterministic code, references for documentation Claude can pull in later, and assets for output files. The progressive loading pattern (metadata always present, body when triggered, resources on demand) is smart and the guidance on what not to include (no READMEs, no changelogs) keeps things lean. Practical advice throughout on splitting large skills and avoiding context bloat.

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.
