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.
Check $ARGUMENTS first to determine execution mode:
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.
Proceed immediately to Task Execution (skip the "loaded" message).
When user requirements are available (either from initial $ARGUMENTS or follow-up message):
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:
DO NOT PROCEED to Step 2 until you have read both files and have the frameworks AND voice rules loaded in context.
Check if FOUNDER_CONTEXT.md exists in the project root.
From the user's requirements, extract:
For any missing information, apply defaults from Defaults & Assumptions.
Using the Framework Selection Matrix and "Choosing Between Frameworks" guidance from copy_frameworks.md:
Primary Framework: Select the best framework based on:
Alternative Framework: Select a genuinely different framework that offers a contrasting approach:
Write the complete copy using the primary framework:
Write the complete copy using the alternative framework:
Hard constraints. No interpretation. Every rule here exists because it kills conversion when broken.
Read writing_styles.md for the full Banned List. These are the critical ones:
## Copy Brief
**Copy type:** [What they're writing]
**Product/Service:** [What they're selling]
**Target audience:** [Who it's for]
**Key transformation:** [What the customer gets]
**Platform constraints:** [Character limits, length, etc.]
---
## Version A: [Primary Framework Name]
**Why this framework:** [1-2 sentences explaining why this is the optimal choice for this copy type]
### Copy:
[Full copy here, formatted appropriately for the platform]
---
## Version B: [Alternative Framework Name]
**Why this framework:** [1-2 sentences explaining why this alternative could work well]
### Copy:
[Full copy here, formatted appropriately for the platform]

## Recommendation
[Which version to test first and why. Any A/B testing suggestions.]
Example:
## Copy Brief
**Copy type:** Facebook Ad
**Product/Service:** AI scheduling tool for founders
**Target audience:** Solo founders working 60+ hour weeks
**Key transformation:** Reclaim 10+ hours per week
**Platform constraints:** 125 char hook, 1000 char max
---
## Version A: AIDA
**Why this framework:** AIDA gives a clean attention-to-action arc. Works well here because the problem is visible but the solution needs a moment to land.
### Copy:
You're working 70 hours a week and still behind.
Last Tuesday I counted how much time I spent just scheduling meetings. 2 hours and 17 minutes. In one day.
CalendarAI handles all of it. Scheduling, rescheduling, confirmations, the whole thing. I set it up in 8 minutes and haven't touched my calendar since.

## Version B: PAS
**Why this framework:** PAS leads with the pain, which is strong here. Founders already feel this daily, so we don't need to explain it. We just need to name it accurately.
### Copy:
Your calendar is running your business. You're not.
You spent 47 minutes yesterday rescheduling a single call. You have 3 "free" slots this week and two of them are back-to-back meetings you forgot about. Meanwhile, the actual work that grows your company keeps getting pushed.
CalendarAI does all of this for you. Schedules, reschedules, sends reminders, blocks your focus time. Set it up once, it runs.
2,400 founders use it. Average time saved: 11 hours a week.
→ Get your first week free. See how it works.

## Recommendation
Test Version B (PAS) first. The pain is real and daily for this audience, so leading with it will get more clicks. If CTR is strong but people aren't converting, swap to Version A, which spends more time on the proof.
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.
Before finalizing output, verify ALL of the following:
./references/copy_frameworks.md before writing copy./references/writing_styles.md before writing copyIf ANY check fails → revise before presenting.
Use these unless the user overrides:
Document any assumptions made in the Copy Brief.
