Most brand style guides are written for people: mood boards, values and a page about “our personality”. Models don’t do well with personality descriptions<\/strong>, but they follow clear rules reliably. The writing prompts in our text collection<\/a> use a short rules block instead of the full brand book.<\/p>\n\n\n\n

This post shows how to turn a style guide into ten rules or fewer<\/strong> that you can check in every output. It works especially well together with a well-written persona<\/a>.<\/p>\n\n\n\n

Why the full brand book doesn’t work<\/h2>\n\n\n\n

A long style guide mixes rules with inspiration. The model can’t tell which sentences are hard requirements and which are background. The result reads roughly<\/em> on-brand: the right mood, the wrong details.<\/p>\n\n\n\n

From description to rule<\/h2>\n\n\n\n

Go through the guide and rewrite every statement as something you could verify in the output:<\/p>\n\n\n\n

    \n\n
  • “We’re friendly but professional” \u2192 Use “you” and “we”. No slang, no emojis.<\/em><\/li>\n\n\n
  • “We value clarity” \u2192 Sentences under 25 words. One idea per paragraph.<\/em><\/li>\n\n\n
  • “We’re confident, not arrogant” \u2192 No superlatives such as “best” or “leading” unless backed by a source.<\/em><\/li>\n\n<\/ul>\n\n\n\n

    A rules block you can reuse<\/h2>\n\n\n\n
    Brand voice rules:\n1. Address the reader as \"you\". Refer to us as \"we\".\n2. Sentences under 25 words. Paragraphs under 4 sentences.\n3. No exclamation marks, emojis or ALL CAPS.\n4. No superlatives (best, leading, revolutionary) without a source.\n5. Use \"sign up\", never \"register\" or \"join now\".\n6. Numbers as digits: 3 steps, 10 minutes.\n7. End with one clear next step, never two.<\/code><\/pre>\n\n\n\n
    Keep the list short<\/h3>\n\n\n\n
    Past ten rules, models start dropping some, and so do the people reviewing the output. If a rule is rarely broken, remove it. If it is broken all the time, move it to the top.<\/p>\n\n\n\n
    \n\n
    If two writers can read a rule and disagree about whether it was followed, it isn’t a rule yet.<\/p>\n\nContent lead<\/cite><\/blockquote>\n\n\n\n
    Store it once, include it everywhere<\/h2>\n\n\n\n
    Save the rules block as a reusable snippet and include it in every writing prompt. When the brand changes a term, you update it in one place, and every prompt in the library follows.<\/p>\n","protected":false},"excerpt":{"rendered":"
