Skill Builder

If you're building custom Claude Code workflows, you'll eventually need to package your own skills, and this walks you through the whole setup. It covers the required YAML frontmatter (name and description fields), progressive disclosure structure, and directory organization that Claude expects. The source shows you exactly where files go (top-level only, no nesting), how to write descriptions that help Claude know when to invoke your skill, and what a complete skill package looks like with scripts and templates. Think of it as the spec and scaffolding tool in one. Most useful when you've hit the limits of existing skills and need something purpose-built for your team's workflow.
