If you're building skills for AI agents and want them to follow the agentskills.io spec properly, this walks you through the full authoring process. It enforces progressive disclosure (keeping core logic under 500 lines), validates metadata with a Python script before you go too far, and structures everything into scripts, references, and assets directories. The third-person imperative style takes some getting used to, but it keeps instructions crisp. Honestly most useful if you're cranking out multiple skills and need a consistent framework, less so if you're just prototyping one-offs. The validation script alone saves you from metadata mistakes that would break discoverability.
