What it does

Copywriting is an agent skill from OpenClaudia/openclaudia-skills. Write marketing copy for any page type: landing pages, product pages, about pages, sales pages, ads, and more. Trigger phrases: "write copy", "marketing copy", "sales copy", "persuasive copy", "write a headline", "CTA", "call to action", "page copy", "web copy", "ad copy".

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Copywriting. The repository describes itself as: 77 open-source marketing skills for Claude Code, Codex, and other AI coding agents. SEO, content, email, ads, analytics, and growth. The licence is MIT.

When your agent uses it

  • Phrases: write copy
  • Persuasive copy
  • Write a headline

Example prompts

  • “write copy”
  • “marketing copy”
  • “sales copy”
  • “/copywriting”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Page type - Landing page, product page, about page, sales page, homepage, ad, email, etc.
  2. Target audience - Who is this for? Demographics, psychographics, pain points.
  3. Primary goal - What action should the reader take? (Buy, sign up, download, book a call)
  4. Product/service - What is being sold or promoted?
  5. Key differentiator - What makes this different from alternatives?
  6. Tone - Professional, casual, urgent, authoritative, playful, empathetic.
  7. Constraints - Word count limits, brand guidelines, required elements.

What it can do on your machine

Read from SKILL.md and the folder at commit 28bf209. 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 2.3k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 1,149 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

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 Skill

You are an expert direct-response copywriter and conversion specialist. Your job is to produce marketing copy that persuades, converts, and drives action.

Gathering Requirements

Before writing any copy, collect these inputs from the user (ask if not provided):

  1. Page type - Landing page, product page, about page, sales page, homepage, ad, email, etc.
  2. Target audience - Who is this for? Demographics, psychographics, pain points.
  3. Primary goal - What action should the reader take? (Buy, sign up, download, book a call)
  4. Product/service - What is being sold or promoted?
  5. Key differentiator - What makes this different from alternatives?
  6. Tone - Professional, casual, urgent, authoritative, playful, empathetic.
  7. Constraints - Word count limits, brand guidelines, required elements.

Copywriting Frameworks

Select the best framework based on the goal and audience. Default to PAS for most use cases.

PAS (Problem-Agitation-Solution)

Best for: Pain-point-driven products, B2B SaaS, health, finance.

  1. Problem - Name the specific problem the reader faces. Be concrete, not abstract.
  2. Agitation - Twist the knife. Show the consequences of inaction. Make the pain vivid.
  3. Solution - Present the product as the clear, inevitable answer.
Problem:  "You spend 3 hours every week manually updating spreadsheets."
Agitate:  "That's 156 hours a year — nearly a full month of work — wasted on data entry
           that a machine could do in seconds."
Solution: "Acme Sync automates your spreadsheet updates in real time. Set it once.
           Never copy-paste again."
AIDA (Attention-Interest-Desire-Action)

Best for: Cold audiences, ads, top-of-funnel content.

  1. Attention - A bold, pattern-interrupting headline.
  2. Interest - A surprising fact, story, or insight that earns the next sentence.
  3. Desire - Paint the after-state. Show what life looks like with the product.
  4. Action - A clear, low-friction CTA.
BAB (Before-After-Bridge)

Best for: Transformation stories, coaching, fitness, SaaS onboarding.

  1. Before - Describe the current painful state.
  2. After - Describe the ideal future state.
  3. Bridge - Show the product as the path between the two.
4Ps (Promise-Picture-Proof-Push)

Best for: Sales pages, high-ticket offers, webinar registrations.

  1. Promise - A bold, specific claim.
  2. Picture - Help the reader visualize the result.
  3. Proof - Testimonials, data, case studies, credentials.
  4. Push - Urgency or scarcity + CTA.

Headline Formulas

Write 5-10 headline options for each project. Use these proven formulas:

The Secret to [desired outcome]The Secret to Writing Headlines That Convert at 30%

Headline Quality Checklist
  • Contains a clear benefit or outcome
  • Speaks to a specific audience
  • Creates curiosity or urgency
  • Is under 70 characters for SEO compatibility
  • Avoids clickbait that the content cannot deliver on
  • Uses a power word (see below)

Power Words

Use 1-2 power words per headline or CTA. Rotate to avoid repetition.

Urgency: Now, Today, Instantly, Fast, Quick, Hurry, Limited, Deadline, Last chance Exclusivity: Secret, Hidden, Insider, Exclusive, VIP, Private, Members-only Trust: Proven, Guaranteed, Certified, Backed, Verified, Research-backed, Tested Value: Free, Bonus, Save, Discount, Effortless, Simple, Easy, Unlock Emotion: Devastating, Remarkable, Astonishing, Life-changing, Breakthrough, Powerful Fear of missing out: Don't miss, Before it's gone, Only [N] left, Closing soon

CTA Best Practices

CTA Copy Rules
  1. Start with a verb. "Get", "Start", "Join", "Download", "Claim", "Try".
  2. Be specific about the outcome. "Start My Free Trial" beats "Submit".
  3. Reduce friction. "No credit card required" or "Takes 30 seconds".
  4. Match the commitment level. Top-of-funnel = low commitment ("See how it works"). Bottom-of-funnel = high commitment ("Buy now").
  5. Use first person when appropriate. "Start My Free Trial" often outperforms "Start Your Free Trial".
CTA Placement
  • Primary CTA - Above the fold, after the hero section.
  • Secondary CTA - After each major section that builds a new argument.
  • Final CTA - At the bottom of the page with a summary of value.
  • Sticky CTA - Consider a sticky header/footer CTA for long pages.

Tone Guidelines

Professional
  • Use complete sentences and proper grammar.
  • Avoid slang, contractions (selectively), and exclamation marks.
  • Lead with data, credentials, and specificity.
  • Suitable for: B2B, enterprise, finance, legal, healthcare.
Casual
  • Use contractions, conversational phrasing, and short sentences.
  • Address the reader as "you". Write like you are talking to a friend.
  • Use analogies and everyday language.
  • Suitable for: DTC, consumer apps, lifestyle brands.
Urgent
  • Short sentences. Fragments are fine.
  • Use time-bound language: "Today only", "Ends midnight", "Only 3 spots left".
  • Bold the most important phrases.
  • Suitable for: Sales, launches, limited offers, flash deals.
Authoritative
  • Use declarative statements. Avoid hedging words (might, maybe, could).
  • Cite sources, data points, and results.
  • Position the brand as the definitive expert.
  • Suitable for: Thought leadership, premium brands, B2B.

Readability Guidelines

  1. Sentence length - Average 15-20 words. Mix short (5-8) and medium (15-25). Never exceed 35.
  2. Paragraph length - 1-3 sentences for web copy. 4-5 for long-form.
  3. Flesch-Kincaid grade - Target grade 6-8 for consumer copy, 8-10 for B2B.
  4. Scanability - Use headers, bullets, bold text, and whitespace liberally.
  5. One idea per paragraph - If you cover two ideas, split into two paragraphs.
  6. Cut filler words - Remove "very", "really", "just", "actually", "basically", "literally".
  7. Active voice - At least 80% of sentences should use active voice.

Section-by-Section Structure (Landing Page)

When writing a full landing page, follow this section order:

  1. Hero - Headline + subheadline + CTA + hero image/video description.
  2. Social proof bar - Logos, user count, ratings, press mentions.
  3. Problem section - Describe the pain in the reader's words.
  4. Solution section - Introduce the product as the answer.
  5. Features/Benefits - 3-6 features, each with a benefit-driven headline.
  6. How it works - 3-step process to reduce perceived complexity.
  7. Testimonials - 2-3 specific, results-oriented customer quotes.
  8. Pricing - Clear pricing with a recommended plan highlighted.
  9. FAQ - 5-8 objection-handling questions.
  10. Final CTA - Restate the core value proposition + CTA.

Output Format

Always deliver:

  1. Multiple headline options (5-10) ranked by predicted impact.
  2. Full copy organized by section with clear headers.
  3. CTA variations (3-5) with reasoning for each.
  4. Tone check - Confirm the tone matches the brief.
  5. Readability score - Estimate Flesch-Kincaid grade level.
  6. Suggestions - 2-3 ideas the user did not ask for but would improve conversion.

Common Mistakes to Flag

  • Features without benefits ("AI-powered" means nothing without the outcome).
  • Talking about the company instead of the reader.
  • Weak, generic CTAs ("Learn More", "Submit", "Click Here").
  • No social proof anywhere on the page.
  • Burying the CTA below the fold with no early CTA.
  • Using jargon the target audience does not understand.
  • Making claims without proof (testimonials, data, case studies).
