A workflow for writing marketing text for pages such as homepages, landing pages, pricing pages, feature pages, and product pages. It starts with the page's goal, audience, offer, evidence, and the action visitors should take.

Use it to draft or rewrite headlines, page sections, value propositions, calls to action, pricing copy, and other marketing content.

It prevents copy from being written without a clear reader, problem, or purpose. The questions help connect the wording to customer concerns and a specific next step.

copywriting — Skill for Claude Code by Cesarjoquin

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Cesarjoquin/Marketing-Skills --skill copywriting

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00174	$0.01746
Opus 5	$0.00087	$0.00873
Sonnet 5	$0.00035	$0.00349
Haiku 4.5	$0.00017	$0.00175

Security

Grade A, and why

copywriting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to copywriting — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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

Simple over complex — "Use" not "utilize," "help" not "facilitate"
Specific over vague — Avoid "streamline," "optimize," "innovative"
Active over passive — "We generate reports" not "Reports are generated"
Confident over qualified — Remove "almost," "very," "really"
Show over tell — Describe the outcome instead of using adverbs
Honest over sensational — Fabricated statistics or testimonials erode trust and create legal liability

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
