What problem does it solve?

Skill Development provides a standardized approach for creating Claude Code plugin skills, ensuring consistent frontmatter, lean SKILL.md bodies, and a clear separation of heavy details into references for maintainability.

Core Features & Use Cases

  • Structured SKILL.md: Ensure frontmatter contains name and description and a concise body.
  • Progressive disclosure: Move details to references/examples/scripts to keep SKILL.md lean.
  • Bundle guidance: Advise on including scripts/references/assets for reusable tooling.
  • Lifecycle guidance: Outline steps from initialization to packaging and iteration.

Quick Start

Follow the Skill Creation Process to initialize or refine a Claude Code plugin skill, then organize content into lean SKILL.md with references.

FAQPage Schema
How do I structure SKILL.md frontmatter for a Claude Code plugin?

To structure SKILL.md frontmatter for a Claude Code plugin, include third-person name and description fields. This ensures the skill meets discovery requirements and can be accurately indexed by the platform.

What is progressive disclosure in Claude Code skill development?

Progressive disclosure in Claude Code skill development is the practice of moving heavy details into separate references and examples. This keeps the main SKILL.md body lean and maintainable while preserving comprehensive guidance.

What's the best way to organize reusable scripts within a plugin skill?

The best way to organize reusable scripts within a plugin skill is to bundle them as dedicated assets alongside your references. This separates executable tooling from core markdown guidance, ensuring clean resource structuring and maintainability.

What steps are needed to package a Claude Code skill for iteration?

Packaging a Claude Code skill requires following lifecycle guidance from initialization to iteration. You draft frontmatter, organize content into a lean SKILL.md, add detailed references or scripts, and finalize the bundle for deployment.

Do I need to include executable scripts in my SKILL.md file?

You do not need to include executable scripts directly in your SKILL.md file. You should keep the markdown body lean with core guidance and include optional executable scripts or assets as separate bundled files when needed.

Why does my Claude Code skill fail discovery requirements?

Your Claude Code skill fails discovery requirements if its frontmatter lacks a proper name and description. Ensure the SKILL.md includes these mandatory fields along with a concise markdown body to satisfy platform indexing.
