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:

Read: ./references/copy_frameworks.md
Read: ./references/writing_styles.md

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.
