anthropics/claude-plugins-officialOfficial

When you're building Claude Code plugins, getting skills right means understanding progressive disclosure: metadata triggers the skill, SKILL.md provides instructions, and bundled resources (scripts, references, assets) load only when needed. This skill walks you through the creation process starting with concrete examples, then planning what belongs in scripts versus references versus assets, then structuring it all with strong triggering descriptions. The distinction between references (docs Claude reads) and assets (files Claude uses in output) is subtle but matters for context efficiency. If you're writing your first skill or wondering why Claude isn't picking up your existing ones, the triggering guidance alone is worth it.

Skill Development for Claude Code Plugins

This skill provides guidance for creating effective skills for Claude Code plugins.

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
