If you're building skills for Claude, this is your onboarding guide. It walks through the complete creation process: gathering concrete usage examples, planning what scripts and references to bundle, and structuring everything with the three-level progressive disclosure system (metadata, SKILL.md body, bundled resources). The guidance on when to use scripts versus references versus assets is specific and useful. Scripts go in when you're rewriting the same code repeatedly, references hold documentation Claude should load as needed, and assets are files that get used in output. What stands out is the emphasis on concrete examples first, then building the reusable components, which keeps you from overengineering abstractions nobody needs.
