If you're building skills for Claude, this is your starting point. It walks you through the anatomy of a skill: the required SKILL.md with YAML frontmatter, how to organize bundled resources like scripts and reference files, and when to use high-freedom text instructions versus low-freedom deterministic scripts. Includes init_skill.py to scaffold new skills and package_skill.py for distribution. The guidance is practical: design around concrete examples, keep the main file concise by moving details to references, iterate based on real usage. It's meta in the best way, a skill that teaches you how to build skills, from the team at Supabase that's been shipping them in production.
