Use when writing or revising any reader-facing prose for this book — chapters in wiki/, the front page, appendices, exercises, sidebars. Encodes Schuyler's writing voice — direct, conversational, honest about limitations, dry humor that never crowds out technical content — adapted for discursive tutorial prose from the README-oriented original. Read BOOK-PLAN.md's "Drafting: process and voice" section first; it governs how prose gets generated, while this skill governs how it should sound. Do NOT use for code comments or commit messages.
