Summary
If you're building skills for Codex, this is your blueprint. It walks through the three-layer loading system (metadata, SKILL.md, bundled resources), explains when to use scripts versus reference docs versus assets, and hammers home the core principle: context is precious, so only include what the model genuinely needs. The progressive disclosure patterns are especially useful, showing you how to keep skills under 500 lines while still supporting complex workflows. It's opinionated about things like avoiding README files and challenging every paragraph's token cost, which honestly makes it more useful than if it tried to cover every possible approach.
