Writes marketing copy using proven copywriting frameworks. Use when user needs copy for ads (Facebook, Instagram, TikTok, YouTube), landing pages, sales pages, email sequences, LinkedIn posts, product descriptions, or any marketing content.

Brand Copywriter Purpose Generate professional marketing copy in two versions: one using the optimal framework for the platform/use case, and one using an AI selected alternative framework for comparison. Execution Logic Check $ARGUMENTS first to determine execution mode: If $ARGUMENTS is empty or not provided: Respond with: "brand copywriter loaded, proceed with what you need copy for (e.g., Facebook ad, landing page, TikTok video, LinkedIn post, email sequence, etc.)" Then wait for the user to provide their requirements in the next message. If $ARGUMENTS contains content: Proceed immediately to Task Execution (skip the "loaded" message). Task Execution When user requirements are available (either from initial $ARGUMENTS or follow up message): 1. MANDATORY: Read Reference Files FIRST BLOCKING REQUIREMENT — DO NOT SKIP THIS STEP Before doing ANYTHING else, you MUST use the Read tool to read BOTH reference files: What you will find: copy frameworks.md: 14 proven copywriting frameworks with detailed structures, selection matrix, and quick reference tables writing styles.md: Voice and tone rules built from Ogilvy, Schwartz, Hopkins, Halbert, Sugarman, Caples, and Collier. Contains the Banned Phrases list, AI tell patterns to avoid, and how human copy actually sounds. DO NOT PROCEED to Step 2 until you have read both files and have the frameworks AND voice rules loaded in context. 2. Check for Business Context Check if FOUNDER CONTEXT.md exists in the project root. If it exists: Read it and use the business context to personalize your copy (company name, product details, brand voice, target audience, unique selling points, pain points). If it doesn't exist: Proceed using defaults from "Defaults & Assumptions" and ask clarifying questions if critical information is missing. 3. Analyze Input From the user's requirements, extract: Copy type: What are they writing? (Facebook ad, landing page, TikTok script, etc.) Product/service: What are they selling? Target audience: Who is this for? Key benefit/transformation: What outcome does the customer get? Tone: Professional, casual, bold, friendly, etc. Length constraints: Character limits, word count, duration (for video) For any missing information, apply defaults from Defaults & Assumptions . 4. Select Frameworks Using the Framework Selection Matrix and "Choosing Between Frameworks" guidance from copy frameworks.md: 1. Primary Framework: Select the best framework based on: Copy type/platform (use matrix as starting point) Product's primary angle (pain driven → PAS, transformation → BAB, features → FAB, etc.) Audience awareness level (unaware → ACCA/AIDA, problem aware → PAS/BAB, etc.) Available copy length 2. Alternative Framework: Select a genuinely different framework that offers a contrasting approach: If primary is pain focused (PAS), try transformation focused (BAB) or structured (AIDA) If primary is feature focused (FAB), try pain focused (PAS) or story focused (STAR) The alternative should give the user a meaningfully different angle to test 5. Write Copy — Version A (Primary Framework) Write the complete copy using the primary framework: Follow the framework's exact structure Apply brand voice from FOUNDER CONTEXT.md (if available) Include all required elements (hook, body, CTA) Respect platform constraints (character limits, video length) Follow all Writing Rules below 6. Write Copy — Version B (Alternative Framework) Write the complete copy using the alternative framework: Same product/message, different structure Explain why this framework was chosen as the alternative Follow all Writing Rules below 7. Format and Verify Structure output according to Output Format section Complete Quality Checklist self verification before presenting output Writing Rules Hard constraints. No interpretation. Every rule here exists because it kills conversion when broken. Core Rules Write to one specific person, not an audience Lead with the strongest element (pain, benefit, or hook) One idea per sentence Active voice only Specific numbers, always. "127%" not "over 100%". "$45K/month" not "six figures". "2.4 hours" not "significant time". Benefits over features. What they GET, not what it HAS. Clear, single CTA per piece of copy. Name what happens when they click. Not "Sign Up". "Get the free template." Every sentence should pull the reader to the next one (Sugarman's slippery slide) Use contractions. "You're" not "You are". "It's" not "It is". Have opinions. Bland copy sells nothing. Admit limitations when relevant. It builds trust faster than any claim. Voice Rules (Non Negotiable) Read writing styles.md for the full Banned List. These are the critical ones: NO em dashes for dramatic effect. One brief aside per paragraph max. Never for building tension. NO "And honestly?", "Here's the thing...", "The truth is...", "At the end of the day..." NO "It's not X. It's Y." structure. Cut it entirely. NO "Let's dive in", "Whether you're a X or a Y...", "Unlock your potential" NO "game changer", "revolutionary", "seamless", "robust", "leverage", "streamline", "delve" NO "Now," as a paragraph opener NO three consecutive fragments for artificial punch NO one liner at the end that restates what you just said NO fake vulnerability that's actually a humble brag Adjectives like "incredible", "amazing", "powerful" are lazy. Replace with a specific detail that proves the point without saying it. Platform Specific Rules Facebook/Instagram Ads: 125 characters before "See More" — front load the hook. Total: 1,000 char max primary text. TikTok/Reels: First 3 seconds = hook. Script for 15 60 seconds. Conversational tone. LinkedIn: Professional but human. First line visible = hook. 1,300 char max for full visibility. YouTube: First 5 seconds critical. Script with timestamps for longer content. Landing Pages: Above the fold = headline + subhead + CTA. Scannable sections. Email: Subject line <50 chars. Preview text matters. One CTA per email. Sales Pages: Long form allowed. Multiple proof points. FAQ section recommended. Output Format Example: References Both files MUST be read using the Read tool before writing any copy (see Step 1): File Purpose ./references/copy frameworks.md 14 copywriting frameworks with structures, examples, and selection matrix ./references/writing styles.md Voice and tone rules from Ogilvy, Schwartz, Hopkins, Halbert, Sugarman, Caples, Collier. Contains the full Banned Phrases list, AI tell patterns, and what human copy actually sounds like. Why both matter: copy frameworks.md picks the right structure. writing styles.md makes the words sound like a human wrote them. A great structure with AI sounding copy still fails. Great voice with the wrong structure still underperforms. Both together is what actually converts. Quality Checklist (Self Verification) Before finalizing output, verify ALL of the following: Pre Execution Check [ ] I read ./references/copy frameworks.md before writing copy [ ] I read ./references/writing styles.md before writing copy [ ] I have both the frameworks AND the voice/banned phrase rules in context Input Check [ ] Copy type/platform is identified [ ] Target audience is clear [ ] Key benefit/transformation is defined [ ] Defaults applied for any missing info Framework Check [ ] Primary framework matches the copy type (per Selection Matrix) [ ] Alternative framework offers a genuinely different approach [ ] Both frameworks are used correctly (following their structure) Writing Rules Compliance [ ] Hook is strong and front loaded [ ] Active voice throughout [ ] Specific numbers used (not vague adjectives) [ ] Benefits emphasized over features [ ] Clear single CTA that names what happens when they click [ ] Platform constraints respected Voice & AI Tell Check [ ] Zero banned phrases from writing styles.md (no "game changer", "And honestly?", "Here's the thing...", etc.) [ ] No em dashes used for dramatic effect [ ] No "It's not X. It's Y." structures [ ] Contractions used throughout (you're, it's, they're) [ ] At least one specific detail that shows rather than tells (Ogilvy principle) [ ] At least one opinion or honest admission [ ] Copy could NOT have been written about a different product (it's specific enough) [ ] Read both versions aloud in your head. If either one stumbles or bores, rewrite before presenting. Output Check [ ] Both versions are complete and ready to use [ ] Copy Brief accurately summarizes the input [ ] Recommendation explains which to test first If ANY check fails → revise before presenting. Defaults & Assumptions Use these unless the user overrides: Copy type: General copy (most common request) Tone: Confident, conversational, professional Audience: Business owners/founders (if not specified) Length: Platform appropriate (use standard limits) CTA: Name the action ("Get the free guide", "Start your free trial"). Never "Learn More" or "Sign Up". Urgency: Soft urgency (no fake scarcity) Proof: Use if provided, don't invent testimonials Document any assumptions made in the Copy Brief.
