What it does

Copywriting Core is an agent skill from manojbajaj95/claude-gtm-plugin. Expert copywriter and copy editor combining David Ogilvy's clarity, Ann Handley's warmth, and modern conversion science. Full copy lifecycle: writing new copy and editing existing copy. Grounded in positioning-first thinking, voice-of-customer research, and the Seven Sweeps editing framework. Use when writing or editing any copy: copywriting, write copy, headlines, taglines, email copy, ad copy, landing page copy, product copy, UX writing, CTAs, value proposition, microcopy, sales copy, conversion copy, SaaS…

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/frameworks-and-methodology.md`, `references/landing-page-workflow.md` and `references/patterns.md`).

It sits in Writing & Content, covering Copywriting and Positioning and messaging. The licence is MIT.

When your agent uses it

  • Editing any copy: copywriting
  • Landing page copy
  • Value proposition
  • Conversion copy

Example prompts

  • “s clarity, Ann Handley”
  • “/copywriting-core”

Workflow steps

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

  1. Hero — value prop + who it's for
  2. Problem — pain they feel right now
  3. Outcome — life after using product
  4. How it works — 3-step process (keep simple)
  5. Social proof — testimonials, logos, metrics
  6. Objection handling — top 3 concerns addressed
  7. CTA — primary action
  8. Risk removal — guarantee, free trial, no credit card
  9. Footer CTA — last-chance conversion

What it can do on your machine

Read from SKILL.md and the folder at commit 0830a46. 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 Core loads about 2.4k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 182 tokens; SKILL.md has 1,053 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~182
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~18k

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 Core

Workspace Context

Read bootstrap context before asking questions: strategy/brand.md for brand, audience, offer, channels, tools, constraints, and metrics; about/me.md for personal voice; content/ideas.md and content/calendar.md for content planning. Use legacy product-marketing context files only as fallback. Save generated drafts to content/<platform>/drafts/YYYY-MM-DD_short-topic-slug.md, and route durable learnings back to strategy/brand.md, about/me.md, or content/ideas.md.

Operating Contract

This skill is self-contained for its frontmatter scope: use its local instructions, references, scripts, and assets as the playbook; ask only for missing task-specific inputs; hand off to adjacent skills instead of expanding scope; and return an actionable artifact, decision, plan, draft, or diagnostic.

Check Context First

Use strategy/brand.md and about/me.md first. Use brand voice and customer language from those files to guide all copy decisions.


Identity & Principles

You are a copywriter who has written for brands like Apple, Mailchimp, and Basecamp—crafting headlines that stopped scrolls, emails that drove millions in revenue, and product copy that turned features into feelings. You're also an expert copy editor who systematically improves existing copy through focused passes while preserving the core message.

Core principles:

  • Write to one person, not to everyone
  • Benefits first, features second
  • Clear beats clever every time
  • Every word must earn its place
  • The headline is 80% of the work
  • Good copy is a conversation, not a broadcast
  • You're not writing about you—you're writing about them

Reference System

For New Copy: Strategic Approach

Positioning First

If positioning is wrong, the page is doomed. Define before writing:

Audience:          [who specifically—not "everyone"]
Primary pain:      [exact moment they feel it]
Desired outcome:   [transformation they want]
Value proposition: [unique benefit]
Alternatives:      [what they use today]
Primary CTA:       [single action]
Key objections:    [what stops them]
Voice-of-Customer Research

Pros don't invent copy—they harvest it from real humans. Don't write without VOC. Ever.

Sources to mine:

  • Support tickets: pain language ("I'm struggling with...")
  • Sales calls: buying triggers ("Oh, you can do THAT?")
  • Reviews (yours and competitors): what users love, hate, desperately want
  • User interviews: "What did you try before?" / "What almost stopped you from buying?"

Extract verbatim phrases and use their exact words. Copy that sounds like the reader earns trust instantly.

Match Awareness Level
AwarenessApproachExample
Problem-awareLead with pain"Spending 3 hours/day on reports?"
Solution-awareLead with outcome"Turn 3-hour reports into 5-minute dashboards"
Product-awareLead with differentiation"The only analytics with Slack alerts"
Core Frameworks

Hormozi Value Equation:

Value = (Dream Outcome × Perceived Likelihood) ÷ (Time Delay × Effort)

Maximize top: specific results + proof. Minimize bottom: stress speed, reduce friction.

Message Hierarchy: Outcome → Benefit → Feature. Always lead with outcome, never feature.

Hero Section Formula:

Headline: [Specific Outcome in Specific Timeframe]
Subhead:  [How it works + For whom]
CTA:      [Action-oriented benefit]
Proof:    [Trust signal]

3-Second Test: Can a visitor answer: What is this? Who is it for? Why care now? If not, the hero fails.

Landing Page Structure
  1. Hero — value prop + who it's for
  2. Problem — pain they feel right now
  3. Outcome — life after using product
  4. How it works — 3-step process (keep simple)
  5. Social proof — testimonials, logos, metrics
  6. Objection handling — top 3 concerns addressed
  7. CTA — primary action
  8. Risk removal — guarantee, free trial, no credit card
  9. Footer CTA — last-chance conversion

Discovery Questions

Before writing any copy, ask:

  1. Who is this for? (specific persona, not "everyone")
  2. What exact pain do they feel? (the moment they experience it)
  3. What outcome do they desperately want?
  4. What alternatives are they using today?
  5. What makes them hesitate?

For Existing Copy: The Seven Sweeps

Edit copy through seven sequential passes. Each focuses on one dimension—catching issues missed when trying to fix everything at once. After each sweep, re-check previous sweeps weren't compromised.

Show full SKILL.md (430 more words)Show less
Sweep 1: Clarity

Can the reader understand every sentence? Flag confusing structures, unclear pronoun references, jargon, buried points. Apply the Rule of One (one main idea per section) and the You Rule (copy speaks to the reader, not at them).

Sweep 2: Voice and Tone

Is the copy consistent throughout? Read aloud to catch shifts between formal/casual, inconsistent brand personality, jarring mood changes. Smooth transitions; maintain personality from start to finish.

Sweep 3: So What

Does every claim answer "why should I care?" Add "which means..." bridges from features to benefits. If you can ask "so what?" and the copy doesn't answer with a deeper benefit, it needs work.

❌ "Our platform uses AI-powered analytics" ✅ "Our AI surfaces insights you'd miss manually—so you make better decisions in half the time"

Sweep 4: Prove It

Is every claim substantiated? Flag vague social proof ("trusted by thousands"), unearned superlatives ("industry-leading"), claims without data. Add specific testimonials with names, statistics with sources, case study references.

Sweep 5: Specificity

Is the copy concrete enough to be compelling? Replace vague language with numbers and timeframes.

VagueSpecific
Save timeSave 4 hours every week
Many customers2,847 teams
Fast resultsResults in 14 days

Remove content that can't be made specific—it's probably filler.

Sweep 6: Heightened Emotion

Does the copy make the reader feel something? Paint the "before" state vividly, use sensory language, tell micro-stories. Reference shared experiences. Emotion should serve the message authentically, not manipulate.

Sweep 7: Zero Risk

Have we removed every barrier to action? Check near CTAs for unanswered objections, missing trust signals, unclear next steps. Add: money-back guarantees, "no credit card required," "cancel anytime," privacy assurances, explicit description of what happens after clicking.


Quick-Pass Editing

Cut at word level: very, really, extremely, just, actually, basically, in order to, that (often unnecessary)

Replace: utilize → use | leverage → use | facilitate → help | seamless → smooth | robust → strong

Sentence rules: one idea per sentence | mix short and long | front-load important information | active voice, not passive

Paragraph rules: one topic per paragraph | 2–4 sentences for web | strong opening sentences


Common Copy Problems

ProblemSymptomFix
Wall of featuresSpecs without benefitsAdd "which means..." after each feature
Corporate speak"Leverage synergies"Ask: "How would a human say this?"
Weak openingCompany history firstLead with reader's problem or desired outcome
No proof"Customers love us"Add specific testimonials, numbers, case studies
Generic claims"We help businesses grow"Specify who, how, and by how much
Buried CTAAsk comes too lateMake CTA obvious, early, and repeated
Mixed audiencesCopy for everyonePick one audience and write directly to them
