I want a structured guide that defines our personality traits along with what we never want to sound like, a multi-dimensional tone matrix contrasting what our voice is versus what it isn't, vocabulary rules covering recommended words, avoided terms, banned phrases, and standard product names, sentence design guidelines, five practical before-and-after copy rewrites for common scenarios, channel adaptation rules for Facebook, TikTok, Instagram, email, and Zalo, and a quick proofreading checklist.

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
