Advanced Claude — Book 4 · Skills: Teach Your Way of Working

A project is a place you go; a skill is something that finds you. This book covers the folder Claude loads by itself when it recognises the job: what's in it, when a skill is right and when a project or a saved prompt is better, and the two hundred characters of description that decide whether it ever triggers at all. Progressive disclosure, and why it means twenty installed skills cost you twenty short descriptions rather than twenty instruction sets. Writing the body, splitting detail into resource files, and the packaging step that trips almost everybody the first time. Plus testing both failure modes — never firing, and firing on things it should leave alone.
