Get Claude to write exactly 3 numbered Midjourney prompts, plain text, under 220 words in total: feed (--ar 1:1), portrait feed (--ar 4:5) and Story (--ar 9:16).

Shot from directly overhead.\n\nBrand colors: navy #1B2A4A, pine green #2E6B4F.\n\nPlacements we bought: feed square, feed portrait, Stories. The Stories ad has the profile name on top and the \"Shop now\" button at the bottom.\n\nNotes:\n- Last summer's ad showed a model's back with sunscreen; legal flagged it (we didn't have a model release).\n- The tube's front text is tiny; it usually comes out garbled, so don't show the label up close.\n- Someone wants a famous lifeguard TV show vibe. Please, no.\n- We tested a sunset version; people thought it was a nighttime product.","rules":[{"type":"numberedItems","count":3},{"type":"maxWords","max":220},{"type":"plainText"}],"mistakes":[{"title":"One prompt for all sizes","why":"The AI writes a single prompt, and cropping it to 9:16 cuts off the product.","fix":"Add: \"Exactly 3 numbered prompts: --ar 1:1, --ar 4:5, --ar 9:16.\"","checks":["numberedItems","r0"]},{"title":"Rewording the scene each time","why":"The AI describes the scene differently in each prompt, so the 3 ads don't match.","fix":"Add: \"Repeat the same scene description word for word.\"","checks":["r1"]},{"title":"Forgetting Story overlays","why":"The profile name and Shop button cover the product in the Story.","fix":"Add to the 9:16 one: \"top and bottom 15% empty\".","checks":["r2"]},{"title":"Headings and notes","why":"The AI labels each prompt with bold headings and tips.","fix":"Add: \"Plain text, no headings, no notes.\"","checks":["plainText","maxWords"]}],"promptHints":[{"label":"Asks for 3 prompts","patterns":["\\b(3|three)\\b.{0,20}prompts"]},{"label":"Gives each ratio","patterns":["1\\s*:\\s*1","4\\s*:\\s*5","9\\s*:\\s*16"]},{"label":"Keeps the scene identical","patterns":["word for word","same scene","identical"]},{"label":"Protects the Story overlays","patterns":["top and bottom","15\\s*%"]},{"label":"Adds exclusions","patterns":["--no"]}],"hint":"Cropping one image to 3 shapes usually ruins at least one.
