If you're building skills for Claude, this is your reference guide. It walks through the full anatomy of a skill file, from YAML frontmatter to bundled scripts and assets, with clear guidance on when to use each. The progressive disclosure pattern is smart: keep SKILL.md under 500 lines, split domain-specific content into reference files, and remember that conciseness matters because context windows are shared across everything. The degrees of freedom framework is especially useful for deciding whether to give text instructions, pseudocode, or locked-down scripts. Honestly just wish this existed as the official docs instead of being packaged as a skill.
