Update Skill

If you're building or maintaining a collection of Claude skills, this is the meta-skill that helps you write and structure the SKILL.md files themselves. It covers the required YAML frontmatter (name and description fields), suggests a typical structure with title, overview, and main content sections, and includes practical guidance on when to split larger skills into reference subdirectories. The emphasis on action-verb descriptions and concrete use cases is smart, it makes skills actually discoverable. Think of this as the style guide and linter rolled into one. You'll reference it when spinning up new skills or refactoring existing ones that have grown messy.
