What it does

Copywriting is an agent skill from coreyhaines31/marketingskills. When the user wants to write, rewrite, or improve marketing copy for any page, including homepage, landing pages, pricing pages, feature pages, about pages, or product pages. Also use when the user says "write copy for," "improve this copy," "rewrite this page," "marketing copy," "headline help," "CTA copy," "value proposition," "tagline," "subheadline," "hero section copy," "above the fold," "this copy is weak," "make this more compelling," "this sounds like AI," "AI slop," "make it sound human," or "help me…

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/ai-tells.md` and `references/copy-frameworks.md`).

It sits in Writing & Content, covering Copywriting, Landing pages and Positioning and messaging. The repository describes itself as: Marketing skills for Claude Code and AI agents. CRO, copywriting, SEO, analytics, and growth engineering. The licence is MIT.

When your agent uses it

  • Improve marketing copy for any page
  • Including homepage
  • The user says write copy for
  • Improve this copy

Example prompts

  • “write copy for,”
  • “improve this copy,”
  • “rewrite this page,”
  • “/copywriting”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Page Purpose
  2. Audience
  3. Product/Offer
  4. Context

What it can do on your machine

Read from SKILL.md and the folder at commit 1efedbc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Copywriting loads about 2.7k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 240 tokens; SKILL.md has 1,347 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~240
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.

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?

Copywriting Principles

Clarity Over Cleverness

If you have to choose between clear and creative, choose clear. Clarity also converts. Clearer positioning and copy is associated with +81% conversions, a 38% shorter sales cycle, 28% lower CAC, and 175% more referrals. When a reader has to decode your line, you've lost them.

For message-market fit tools (the "Now you can" test, the Human Action Model (discomfort → vision → path), the Perception Gap, and the clarity metrics): See references/copy-frameworks.md

Benefits Over Features

Features: What it does. Benefits: What that means for the customer.

Specificity Over Vagueness
  • Vague: "Save time on your workflow"
  • Specific: "Cut your weekly reporting from 4 hours to 15 minutes"
Customer Language Over Company Language

Use words your customers use. Mirror voice-of-customer from reviews, interviews, support tickets.

One Idea Per Section

Each section should advance one argument. Build a logical flow down the page.


Writing Style Rules

Core Principles
  1. Simple over complex: "Use" not "utilize," "help" not "facilitate"
  2. Specific over vague: Avoid "streamline," "optimize," "innovative"
  3. Active over passive: "We generate reports" not "Reports are generated"
  4. Confident over qualified: Remove "almost," "very," "really"
  5. Show over tell: Describe the outcome instead of using adverbs
  6. Honest over sensational: Fabricated statistics or testimonials erode trust and create legal liability
Quick Quality Check
  • Any AI tells? (see No AI Tells below)
  • Jargon that could confuse outsiders?
  • Sentences trying to do too much?
  • Passive voice constructions?
  • Exclamation points? (remove them)
  • Marketing buzzwords without substance?

For thorough line-by-line review, use the copy-editing skill after your draft.


No AI Tells

Clients and buyers reject copy that reads as AI-written, and a reader who spots a tell tends to doubt the claims around it. Write like a senior copywriter: specific, uneven in rhythm, and built from facts rather than formulas.

Never write these
  1. Contrast reveals. "It's not X, it's Y." "Not because X. Because Y." "Not just X, but Y." State Y directly, with the reason.
  2. Negation lists. "No setup call, no templates, no waiting on IT. No contract." Say what does happen. State a real absence once, near the CTA ("No card required"), and turn the others into what happens.
  3. Trailing pile-ons. A full claim followed by a comma and more clauses: "...the data you already have, no exports, no spreadsheets, no second copy." End the sentence at the claim.
  4. Self-answered questions and colon reveals. "The result? 3x faster." "The best part: it learns." Just say it. FAQ questions and a reader's own question ("Need to share a screenshot?") are fine.
  5. Stock openers and phrases. "In today's fast-paced world," "Whether you're X or Y," "Here's the thing," "Say goodbye to," "X, reimagined," "Unlock the power of," "Take it to the next level."
  6. Em dashes in short copy. Headlines, subheads, ads, social posts, and subject lines use none.
Keep these rare
  • At most one fragment and one list of three per section (a hero, a page section, or one short post). CTA microcopy and a real three-feature list are fine.
  • Words like seamless, robust, powerful, unlock, and streamline: replace them with the fact they stand in for.
  • Swap test: if a line would work unchanged on a competitor's site, rewrite it. If you lack the differentiator to fix it, flag [NEED: differentiator].
Check before delivering

Before handing over any draft, run the self-check in references/ai-tells.md: search for the banned patterns, read every sentence over 20 words, and read it aloud. Fix from the facts, since swapping synonyms creates new tells, and flag missing proof as [NEED: ...] rather than inventing it.

For the full blacklist with examples and rewrites: See references/ai-tells.md


Best Practices

Be Direct

Get to the point. Don't bury the value in qualifications.

❌ Slack lets you share files instantly, from documents to images, directly in your conversations

✅ Need to share a screenshot? Send as many documents, images, and audio files as your heart desires.

Show full SKILL.md (531 more words)Show less
Use Rhetorical Questions

A question that names the reader's pain can open a section well.

  • "Hate returning stuff to Amazon?"
  • "Tired of chasing approvals?"

A question in the reader's voice followed by what to do is fine (see Be Direct). A question that labels your own claim ("The result? 3x faster.") is an AI tell.

Use Analogies When Helpful

Analogies make abstract concepts concrete and memorable.

Pepper in Humor (When Appropriate)

Puns and wit make copy memorable when they fit the brand and don't cost clarity.


Page Structure Framework

Above the Fold

Headline

  • Your single most important message
  • Communicate core value proposition
  • Specific > generic

Example formulas:

  • "{Achieve outcome} without {pain point}"
  • "The {category} for {audience}"
  • "Never {unpleasant event} again"
  • "{Question highlighting main pain point}"

For comprehensive headline formulas: See references/copy-frameworks.md

Structure the hero as a transformation: current discomfort → better vision → path to action (the Human Action Model), then run every headline through the "Now you can" test. See references/copy-frameworks.md

For natural transition phrases: See references/natural-transitions.md

Subheadline

  • Expands on headline
  • Adds specificity
  • 1-2 sentences max

Primary CTA

  • Action-oriented button text
  • Communicate what they get: "Start Free Trial" > "Sign Up"
Core Sections
SectionPurpose
Social ProofBuild credibility (logos, stats, testimonials)
Problem/PainShow you understand their situation
Solution/BenefitsConnect to outcomes (3-5 key benefits)
How It WorksReduce perceived complexity (3-4 steps)
Objection HandlingFAQ, comparisons, guarantees
Final CTARecap value, repeat CTA, risk reversal

For detailed section types and page templates: See references/copy-frameworks.md


CTA Copy Guidelines

Weak CTAs (avoid):

  • Submit, Sign Up, Learn More, Click Here, Get Started

Strong CTAs (use):

  • Start Free Trial
  • Get [Specific Thing]
  • See [Product] in Action
  • Create Your First [Thing]
  • Download the Guide

Formula: [Action Verb] + [What They Get] + [Qualifier if needed]

Examples:

  • "Start My Free Trial"
  • "Get the Complete Checklist"
  • "See Pricing for My Team"

Page-Specific Guidance

Homepage
  • Serve multiple audiences without being generic
  • Lead with broadest value proposition
  • Provide clear paths for different visitor intents
Landing Page
  • Single message, single CTA
  • Match headline to ad/traffic source
  • Complete argument on one page
Pricing Page
  • Help visitors choose the right plan
  • Address "which is right for me?" anxiety
  • Make recommended plan obvious
Feature Page
  • Connect feature → benefit → outcome
  • Show use cases and examples
  • Clear path to try or buy
About Page
  • Tell the story of why you exist
  • Connect mission to customer benefit
  • Still include a CTA

Voice and Tone

Before writing, establish:

Formality level:

  • Casual/conversational
  • Professional but friendly
  • Formal/enterprise

Brand personality:

  • Playful or serious?
  • Bold or understated?
  • Technical or accessible?

Maintain consistency, but adjust intensity:

  • Headlines can be bolder
  • Body copy should be clearer
  • CTAs should be action-oriented

Output Format

When writing copy, provide:

Page Copy

Organized by section:

  • Headline, Subheadline, CTA
  • Section headers and body copy
  • Secondary CTAs
Annotations

For key elements, explain:

  • Why you made this choice
  • What principle it applies
Alternatives

For headlines and CTAs, provide 2-3 options:

  • Option A: [copy]. Rationale: [why]
  • Option B: [copy]. Rationale: [why]
Meta Content (if relevant)
  • Page title (for SEO)
  • Meta description

  • copy-editing: For polishing existing copy (use after your draft)
  • cro: If page structure/strategy needs work, not just copy
  • emails: For email copywriting
  • popups: For popup and modal copy
  • ab-testing: To test copy variations
