Copywriting is an agent skill that supplies headline formulas and landing-page structure templates for solo builders shipping dev-tool and SaaS go-to-market pages.

About

Copywriting is an agent skill from Infrasity’s dev-GTM Claude skills pack—a reference library of headline formulas, landing section types, and full page structure templates tuned for builders who must ship credible marketing pages without a dedicated copy team. It catalogs outcome-led hooks (“achieve X without Y”), problem-led reversals, audience-specific positioning lines, and proof-driven claims, then maps them into repeatable page skeletons from compact single-page landers to enterprise B2B layouts and product-launch narratives. Section tips push you to articulate pain, benefits, mechanism, and testimonial selection instead of feature dumps alone. Solo operators use it while validating demand on a landing page, refreshing positioning before launch, or drafting lifecycle email heroes that reuse the same formulas. The skill is template-forward prose guidance for agents, not a live analytics or A/B testing integration—bring your own voice, metrics, and brand constraints.

  • Headline formulas grouped by outcome, problem, audience, differentiation, and proof angles
  • Core and supporting landing section types with tips for problem, benefits, how-it-works, and testimonials
  • Page structure templates: feature-heavy, varied engaging, compact, enterprise B2B, and product launch layouts
  • Section-level writing guidance so agents do not skip problem narrative or social proof blocks
  • Dev-GTM oriented reference meant to pair with positioning work before paid acquisition

What it does

Draft and structure landing-page copy using proven headline formulas, section types, and page templates instead of staring at a blank marketing doc.

Who is it for?

Best when you're publishing validation landers, dev-tool launches, and compact SaaS pages and want frameworks instead of generic “write marketing copy” prompts.

Skip if: Long-form SEO editorial calendars, paid ad creative testing platforms, or teams that already enforce a strict brand voice guide with legal review.

When should I use this skill?

You are writing or restructuring a marketing or landing page and need headline formulas, section types, and page templates rather than freeform fluff.

What you get

You get agent-drafted page copy organized by formula and template—ready to paste into your site builder and iterate with real visitor feedback.

  • Headline options by formula type
  • Section-by-section landing page draft
  • Page layout chosen from a named structure template

By the numbers

  • 5 headline formula families (outcome, problem, audience, differentiation, proof) plus additional formulas
  • 5 page structure templates including enterprise B2B and product launch
  • 4 section writing tip areas: problem, benefits, how it works, testimonials

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.

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

  • Jargon that could confuse outsiders?
  • Sentences trying to do too much?
  • Passive voice constructions?
  • Exclamation points? (remove them)
  • Marketing buzzwords without substance?

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.

Use Rhetorical Questions

Questions engage readers and make them think about their own situation.

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

Use Analogies When Helpful

Analogies make abstract concepts concrete and memorable.

Pepper in Humor (When Appropriate)

Puns and wit make copy memorable—but only if it fits the brand and doesn't undermine 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

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"

Maintain consistency, but adjust intensity:
