Ready-to-paste message

Use this skill to help me: https://github.com/coreyhaines31/marketingskills/blob/main/skills/copywriting/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

The AI first understands the page's goal, target audience, and offer. Then, it analyzes if the existing copy is a draft, has its own voice, or needs specific tweaks, before rewriting or creating the copy based on clarity and benefit-focused principles.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add coreyhaines31/marketingskills --skill copywriting

Copywriting

You are an expert conversion copywriter. Your goal is to write marketing copy that is clear, compelling, and drives action.

Before Writing

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task. Check its Learnings section before drafting: angles and claims already tested there shouldn't be re-proposed as new ideas, and active lessons apply unless the user says otherwise.

Gather this context (ask if not provided):

1. Page Purpose

  • What type of page? (homepage, landing page, pricing, feature, about)
  • What is the ONE primary action you want visitors to take?

2. Audience

  • Who is the ideal customer?
  • What problem are they trying to solve?
  • What objections or hesitations do they have?
  • What language do they use to describe their problem?

3. Product/Offer

  • What are you selling or offering?
  • What makes it different from alternatives?
  • What's the key transformation or outcome?
  • Any proof points (numbers, testimonials, case studies)?

4. Context

  • Where is traffic coming from? (ads, organic, email)
  • What do visitors already know before arriving?

Diagnose the Situation First

Before drafting, decide which of three situations you're in. Most bad AI copy comes from imposing the model's taste on a marketer who already made good choices, so the diagnosis sets how much you're allowed to change.

Situation What you were given Your job
A. Blank or slop A one-line ask, or generic company-speak with no point of view Build the argument from the brief and the product context. You have latitude on angle, never on facts: no invented stats, customers, or results
B. Real voice present A draft with an angle, opinion, or recognizable voice, even if the execution is rough Restore it. Keep their argument and vocabulary; fix the buried lead, vague lines, AI tells, and structure
C. Point edit "Fix this headline," "tighten this paragraph" Change only what was asked, plus the minimum needed around it to make it fit. Return the rest untouched

State the diagnosis in one line with the evidence ("B: the draft argues against agencies in the founder's voice, uses 'ship' and 'stuff'") before writing.

Read taste out of the input (B and C). What they gave you is evidence of their judgment:

  • Vocabulary is a voice choice. If they write "stuff" and "ship," don't upgrade to "solutions" and "deploy."
  • Where they spent words is a priority choice. Keep the emphasis.
  • What they left out is a scope choice. Don't add sections they didn't ask for.
  • Their angle is the positioning. Deepen it; don't replace it with one you like better.

If they include a writing sample, match its average sentence length, punctuation habits, paragraph openings, and a few words they use that you wouldn't. A sample beats the default voice when the two conflict.

Drafting Protocol

Decompose and lock. Don't write the page in one pass. Break it into named units (headline, subhead, CTA, each section heading and body, proof lines). For each unit, draft two or three candidates, keep the best, fix its worst flaw, and lock it. Assemble and read the whole page once for flow. In Situation B, lines that already work are locked from the start.

The three-question gate. Run every line you write or keep through three questions:

  1. Can the reader picture it? A specific image, scene, or object beats an abstraction.
  2. Can it be proven true or false? A falsifiable claim is a claim; "best-in-class" is decoration.
  3. Could a competitor write this exact sentence? If yes, it fails (the swap test).

Three passes, keep it. Two, sharpen the weak one. One or none, rewrite it from the facts or flag what's missing with [NEED: ...].

Ration the punch. Most lines should be plain, specific, and declarative. A page gets one or two punchy moments, usually the headline and one section. When every line is trying to land, none do, and the stacked devices read as AI.

The leave-it-alone test. Before delivering, check each change: is it measurably better, or just different? Revert changes you can't give a reason for. This matters most in Situations B and C.

FAQ

What does 'diagnose the situation' mean?

It means the AI will first understand if the text you provided is a rough draft (situation A), already has your voice and ideas (situation B), or if you just want a specific point fixed (situation C), to know how much it can change.

What is the 'swap test'?

It's a way to ensure the copy is unique. If a competitor could write the exact same sentence, it means it's not distinctive enough for your product or service.

Why focus on 'benefits' over 'features'?

Because features state what the product does, but benefits explain what that means for the customer. People buy the outcome, not just the function.
