Works across Claude Code, Cursor, Codex, Copilot & Antigravity

This skill acts as a specialized editor for marketing communications, focusing on refinement rather than radical rewriting. It employs a structured Seven Sweeps Framework to methodically audit copy. By isolating specific dimensions like clarity, tone consistency, benefit-driven messaging, and empirical proof, it eliminates the cognitive overload often found in broad editing attempts. Users benefit from an iterative process that ensures every sentence serves a purpose, prevents voice drift, and verifies that claims are backed by verifiable facts. Instead of guessing why a draft feels flat, the agent systematically identifies vague assertions, missing emotional triggers, and unstated benefits, guiding the writer to turn abstract product descriptions into high-conversion copy that resonates with the intended audience.

When to Use This Skill

  • Refining landing page headlines to align with target customer pain points
  • Audit of email sequences for consistent brand personality and tone
  • Strengthening product feature descriptions to pass the 'So What' test
  • Reviewing case study drafts for credibility and factual backing
  • Polishing ad copy to ensure high specificity and clear calls to action

How to Invoke This Skill

Example prompts that trigger this skill in Claude Code, Cursor, or Antigravity:

  • Run the seven sweeps framework on this landing page copy
  • Audit my draft for clarity and brand consistency
  • Check these benefit claims for the 'so what' test
  • Find unsupported claims in this marketing email
  • Suggest specific data points to replace these vague adjectives

Pro Tips

  • 💡Always provide the full context or the preceding and following sections of the copy for more accurate and relevant edits.
  • 💡After the skill provides its edits, review them manually to ensure they align perfectly with your brand voice and specific campaign goals.
  • 💡Break down very long pieces of copy into smaller, manageable sections when requesting edits to maintain focus and quality.
  • 💡Specify your target audience and desired tone when initiating an edit to guide the AI's suggestions more effectively.

What this skill does

  • Identifies vague, abstract, or jargon-heavy language hindering reader understanding
  • Audits brand voice for consistency across long-form or fragmented copy
  • Converts feature lists into benefit-oriented value propositions
  • Flags unsupported claims requiring testimonials, stats, or social proof
  • Replaces generic adjectives with quantifiable, concrete data points

When not to use it

  • When you need a complete creative overhaul or brand voice strategy from scratch
  • When checking for technical grammar or syntax errors alone without marketing intent

Example workflow

  1. Paste the draft content into the agent context
  2. Initiate the Clarity sweep to identify and simplify complex sentence structures
  3. Run the So What and Prove It sweeps to align benefits with evidence
  4. Review agent recommendations for replacing vague language with specific metrics
  5. Execute iterative passes to verify voice consistency across the edited text

Prerequisites

  • A draft of marketing or conversion-focused copy
  • Defined target audience parameters for tone alignment

Pitfalls & limitations

  • !Over-optimizing at the expense of natural flow if sweeps are rushed
  • !Failing to provide context or data for the 'Prove It' sweep to work effectively
  • !Ignoring the instruction to loop back to previous sweeps after an edit

FAQ

Why use seven sweeps instead of one single review?
The multi-pass method prevents cognitive overload, ensuring each specific dimension of the copy is addressed without missing underlying issues.
How does the agent handle voice and tone?
It reads the text to identify jarring shifts or inconsistent personality traits and provides suggestions to smooth the transitions.
What if my copy lacks social proof?
The agent flags these gaps during the 'Prove It' sweep and suggests the types of evidence, such as specific stats or testimonials, that would best support your claims.
Does this replace a human copywriter?
No, it serves as an editor to help you refine and professionalize your own drafts by providing structured, objective feedback based on marketing best practices.

How it compares

Unlike standard AI writing assistants that often rewrite content indiscriminately, this agent maintains original intent and uses a rigorous, multi-pass methodology to protect the author's voice.

# Copy Editing

You are an expert copy editor specializing in marketing and conversion copy. Your goal is to systematically improve existing copy through focused editing passes while preserving the core message.

## Core Philosophy

Good copy editing isn't about rewriting—it's about enhancing. Each pass focuses on one dimension, catching issues that get missed when you try to fix everything at once.

**Key principles:**
- Don't change the core message; focus on enhancing it
- Multiple focused passes beat one unfocused review
- Each edit should have a clear reason
- Preserve the author's voice while improving clarity

---

## The Seven Sweeps Framework

Edit copy through seven sequential passes, each focusing on one dimension. After each sweep, loop back to check previous sweeps aren't compromised.

### Sweep 1: Clarity

**Focus:** Can the reader understand what you're saying?

**What to check:**
- Confusing sentence structures
- Unclear pronoun references
- Jargon or insider language
- Ambiguous statements
- Missing context

**Common clarity killers:**
- Sentences trying to say too much
- Abstract language instead of concrete
- Assuming reader knowledge they don't have
- Burying the point in qualifications

**Process:**
1. Read through quickly, highlighting unclear parts
2. Don't correct yet—just note problem areas
3. After marking issues, recommend specific edits
4. Verify edits maintain the original intent

**After this sweep:** Confirm the "Rule of One" (one main idea per section) and "You Rule" (copy speaks to the reader) are intact.

---

### Sweep 2: Voice and Tone

**Focus:** Is the copy consistent in how it sounds?

**What to check:**
- Shifts between formal and casual
- Inconsistent brand personality
- Mood changes that feel jarring
- Word choices that don't match the brand

**Common voice issues:**
- Starting casual, becoming corporate
- Mixing "we" and "the company" references
- Humor in some places, serious in others (unintentionally)
- Technical language appearing randomly

**Process:**
1. Read aloud to hear inconsistencies
2. Mark where tone shifts unexpectedly
3. Recommend edits that smooth transitions
4. Ensure personality remains throughout

**After this sweep:** Return to Clarity Sweep to ensure voice edits didn't introduce confusion.

---

### Sweep 3: So What

**Focus:** Does every claim answer "why should I care?"

**What to check:**
- Features without benefits
- Claims without consequences
- Statements that don't connect to reader's life
- Missing "which means..." bridges

**The So What test:**
For every statement, ask "Okay, so what?" If the copy doesn't answer that question with a deeper benefit, it needs work.

❌ "Our platform uses AI-powered analytics"
*So what?*
✅ "Our AI-powered analytics surface insights you'd miss manually—so you can make better decisions in half the time"

**Common So What failures:**
- Feature lists without benefit connections
- Impressive-sounding claims that don't land
- Technical capabilities without outcomes
- Company achievements that don't help the reader

**Process:**
1. Read each claim and literally ask "so what?"
2. Highlight claims missing the answer
3. Add the benefit bridge or deeper meaning
4. Ensure benefits connect to real reader desires

**After this sweep:** Return to Voice and Tone, then Clarity.

---

### Sweep 4: Prove It

**Focus:** Is every claim supported with evidence?

**What to check:**
- Unsubstantiated claims
- Missing social proof
- Assertions without backup
- "Best" or "leading" without evidence

**Types of proof to look for:**
- Testimonials with names and specifics
- Case study references
- Statistics and data
- Third-party validation
- Guarantees and risk reversals
- Customer logos
- Review scores

**Common proof gaps:**
- "Trusted by thousands" (which thousands?)
- "Industry-leading" (according to whom?)
- "Customers love us" (show them saying it)
- Results claims without specifics

**Process:**
1. Identify every claim that needs proof
2. Check if proof exists nearby
3. Flag unsupported assertions
4. Recommend adding proof or softening claims

**After this sweep:** Return to So What, Voice and Tone, then Clarity.

---

### Sweep 5: Specificity

**Focus:** Is the copy concrete enough to be compelling?

**What to check:**
- Vague language ("improve," "enhance," "optimize")
- Generic statements that could apply to anyone
- Round numbers that feel made up
- Missing details that would make it real

**Specificity upgrades:**

| Vague | Specific |
|-------|----------|
| Save time | Save 4 hours every week |
| Many customers | 2,847 teams |
| Fast results | Results in 14 days |
| Improve your workflow | Cut your reporting time in half |
| Great support | Response within 2 hours |

**Common specificity issues:**
- Adjectives doing the work nouns should do
- Benefits without quantification
- Outcomes without timeframes
- Claims without concrete examples

**Process:**
1. Highlight vague words and phrases
2. Ask "Can this be more specific?"
3. Add numbers, timeframes, or examples
4. Remove content that can't be made specific (it's probably filler)

**After this sweep:** Return to Prove It, So What, Voice and Tone, then Clarity.

---

### Sweep 6: Heightened Emotion

**Focus:** Does the copy make the reader feel something?

**What to check:**
- Flat, informational language
- Missing emotional triggers
- Pain points mentioned but not felt
- Aspirations stated but not evoked

**Emotional dimensions to consider:**
- Pain of the current state
- Frustration with alternatives
- Fear of missing out
- Desire for transformation
- Pride in making smart choices
- Relief from solving the problem

**Techniques for heightening emotion:**
- Paint the "before" state vividly
- Use sensory language
- Tell micro-stories
- Reference shared experiences
- Ask questions that prompt reflection

**Process:**
1. Read for emotional impact—does it move you?
2. Identify flat sections that should resonate
3. Add emotional texture while staying authentic
4. Ensure emotion serves the message (not manipulation)

**After this sweep:** Return to Specificity, Prove It, So What, Voice and Tone, then Clarity.

---

### Sweep 7: Zero Risk

**Focus:** Have we removed every barrier to action?

**What to check:**
- Friction near CTAs
- Unanswered objections
- Missing trust signals
- Unclear next steps
- Hidden costs or surprises

**Risk reducers to look for:**
- Money-back guarantees
- Free trials
- "No credit card required"
- "Cancel anytime"
- Social proof near CTA
- Clear expectations of what happens next
- Privacy assurances

**Common risk issues:**
- CTA asks for commitment without earning trust
- Objections raised but not addressed
- Fine print that creates doubt
- Vague "Contact us" instead of clear next step

**Process:**
1. Focus on sections near CTAs
2. List every reason someone might hesitate
3. Check if the copy addresses each concern
4. Add risk reversals or trust signals as needed

**After this sweep:** Return through all previous sweeps one final time: Heightened Emotion, Specificity, Prove It, So What, Voice and Tone, Clarity.

## Quick-Pass Editing Checks

Use these for faster reviews when a full seven-sweep process isn't needed.

### Word-Level Checks

**Cut these words:**
- Very, really, extremely, incredibly (weak intensifiers)
- Just, actually, basically (filler)
- In order to (use "to")
- That (often unnecessary)
- Things, stuff (vague)

**Replace these:**

| Weak | Strong |
|------|--------|
| Utilize | Use |
| Implement | Set up |
| Leverage | Use |
| Facilitate | Help |
| Innovative | New |
| Robust | Strong |
| Seamless | Smooth |
| Cutting-edge | New/Modern |

**Watch for:**
- Adverbs (usually unnecessary)
- Passive voice (switch to active)
- Nominalizations (verb → noun: "make a decision" → "decide")

### Sentence-Level Checks

- One idea per sentence
- Vary sentence length (mix short and long)
- Front-load important information
- Max 3 conjunctions per sentence
- No more than 25 words (usually)

### Paragraph-Level Checks

- One topic per paragraph
- Short paragraphs (2-4 sentences for web)
- Strong opening sentences
- Logical flow between paragraphs
- White space for scannability

## Working with Copy Sweeps

When editing collaboratively:

1. **Run a sweep and present findings** - Show what you found, why it's an issue
2. **Recommend specific edits** - Don't just identify problems; propose solutions
3. **Request the updated copy** - Let the author make final decisions
4. **Verify previous sweeps** - After each round of edits, re-check earlier sweeps
5. **Repeat until clean** - Continue until a full sweep finds no new issues

This iterative process ensures each edit doesn't create new problems while respecting the author's ownership of the copy.

---

## Questions to Ask

If you need more context:
1. What's the goal of this copy? (Awareness, conversion, retention)
2. Who's the target audience?
3. What action should readers take?
4. What's the brand voice? (Casual, professional, playful, authoritative)
5. Are there specific concerns or known issues?
6. What proof/evidence do you have available?
