Summary

If you're building Claude Code Skills and want to skip the boilerplate setup, this handles the scaffolding work. It generates the YAML frontmatter, progressive disclosure architecture, and folder structure that Claude needs to discover and use skills across its surfaces. The skill walks you through creating properly formatted SKILL.md files with examples and best practices baked in. It's meta in the best way: a skill that helps you write skills. Most useful when you're spinning up multiple skills or want to make sure you're following the current spec without constantly referencing docs. Saves time on the mechanical parts so you can focus on what your skill actually does.
