Most AI sales pages fail in the same place. The headline is fine. The bullets are fine. Then the page hits the offer, the guarantee and the “why buy now” section, and the model starts making things up: a testimonial from “Sarah K.”, a timer that resets on refresh, “only 7 spots left”.
A good Claude Code skill fixes that by giving Claude a structure to follow and a list of things it is not allowed to invent.
Quick pick: start with Corey Haines’ free marketingskills (copywriting, offers, CRO and copy-editing skills), add ClawFu’s free sales-letter-writer for true long-form letters (the repo is now archived, so copy it and maintain it yourself), and finish with a humanizer pass. Paid packs add volume, not a different method. Below: which skills to install for long-form sales pages, what each one actually contains, how to install it, what the paid packs cost, and where the legal lines sit on reviews and urgency.

What are Claude Code skills for sales pages?
Direct answer: Claude Code skills for sales pages are folders containing a SKILL.md file that teach Claude a sales-copy method, such as a long-form letter structure, an offer-building process, an objection map or a PAS/AIDA framework. Claude loads the skill when your request matches its description, then writes to that method instead of from generic habits.
Skills live in ~/.claude/skills/ (available everywhere) or .claude/skills/ inside a project (available in that project only). You can also get them bundled in plugins through /plugin marketplaces, or install them with the open Skills CLI: npx skills add owner/repo. If you are new to the format, start with what Claude Code skills are and how to install Claude Code skills.
Why this matters for sales pages in particular: a sales page is the longest, most structured copy job most marketers do. It has a fixed order of jobs (attention, problem, mechanism, proof, offer, risk reversal, call to action), and a model left to itself tends to skip the hard parts. A skill turns that order into instructions Claude reads every time.
| Sales page job | What a good skill should force |
|---|---|
| Headline and lead | One reader, one promise, one reason to keep reading |
| Problem and agitation | The reader’s real cost, not melodrama |
| Mechanism | Why this works when other options did not |
| Proof | Only proof you supply; placeholders for the rest |
| Offer stack | What they get, priced honestly |
| Objections | Named, answered, in the reader’s words |
| Guarantee | Terms you will actually honor |
| Urgency | A real deadline or none |
| Close | One clear call to action |
Takeaway: a sales page skill is valuable for its structure and for its refusals. Judge every skill below on both.
The best Claude Code skills for sales pages in 2026
Direct answer: for most people the best free starting point is Corey Haines’ marketingskills repo (copywriting, cro, offers, copy-editing and marketing-psychology skills), plus ClawFu’s sales-letter-writer for true long-form letters, and a humanizer skill for the final pass. Paid packs add volume, not a different method.
Here is each option, with the source, cost, what it does and the install command taken from its own README.
1. coreyhaines31/marketingskills (free)
- Source: github.com/coreyhaines31/marketingskills
- GitHub: 57,803 stars, last push 31 October 2026
- Price: free
- What it does: a large marketing library. The skills that matter for sales pages are
copywriting,cro(the README’s current name for page conversion work),offers,copy-editing,marketing-psychology,pricingandcustomer-research. - Install:
npx skills add coreyhaines31/marketingskills --skill cro copywritingfor a subset, ornpx skills add coreyhaines31/marketingskillsfor everything. The README warns that if you ask Claude Code to run the command for you, the CLI can install to.agents/skills/, which Claude Code does not read, so pass-a claude-code.
This is the broadest free set and the one most marketers already have. See Claude Code skills for marketers for the full tour.
2. ClawFu sales-letter-writer, dan-kennedy-copy and boron-letters (free)
- Source: github.com/guia-matthieu/clawfu-skills
- GitHub: 150 stars, last push 1 October 2026. The repo is now archived (read-only), so expect no updates or fixes. Copy the skills you want and maintain them yourself.
- Price: free (MIT licence per the skill frontmatter)
- What it does:
sales-letter-writerdescribes itself as writing long-form direct response letters using Gary Halbert’s Boron Letters and Dan Kennedy’s The Ultimate Sales Letter. The same repo hasdan-kennedy-copy,boron-letters,grand-slam-offers(offer construction) andobjection-mapping. - Install: the README gives
git clone https://github.com/guia-matthieu/clawfu-skills.git, then copy the folders you want into~/.claude/skills/or use--add-dir. It also offers an MCP server vianpx @clawfu/mcp-skills.
This is the closest thing to a classic long-form sales letter in skill form. The star count is small, so read the SKILL.md before you rely on it.

7. Directory finds: direct-response-copy variants (free)
Marketplaces and directories such as claudemarketplaces.com, claudskills.com and skills.sh list several direct-response-copy skills, including versions from sanky369/vibe-building-skills (31 stars, last push 12 July 2026) and majesticlabs-dev/majestic-marketplace (50 stars, last push 10 September 2026). They are small, single-author skills. Useful for ideas; check the SKILL.md and the repo before installing. ComposioHQ/awesome-claude-skills (78,504 stars, last push 18 September 2026) is a curated list worth browsing for more.
8. Paid packs
| Pack | Where | Price (checked 1 Nov 2026) | What you get, per the seller |
|---|---|---|---|
| Master Marketing Skills Bundle (Inflectual) | Gumroad | $167 one-time | 167 skills in 16 categories |
| Ultimate Claude SEO & AEO Skills Pack | Contra | $39 (shown against $79) | SEO and AEO skills for auditing, planning and writing |
| SuperSkills | superskills-one.vercel.app | $50 one-time | 139 Claude Code skills delivered as a ZIP |
Skill counts are the sellers’ claims and are unconfirmed. None of these is built mainly for sales pages: the Inflectual bundle and SuperSkills are general packs, and the Contra pack is SEO-focused (useful if your sales page also has to rank, see Claude Code skills for SEO). Install is usually unzipping into ~/.claude/skills/; follow the seller’s instructions.
Left out on purpose: Claude Skills 360 lists a $39 one-time price, but its page shows “20% OFF, Limited Time” with no end date, which is the kind of open-ended urgency this guide tells you not to use. It is excluded for that reason.
Takeaway: start free. The free repos above cover every section of a sales page. Buy a pack only if you want breadth across many marketing jobs.
Free vs paid: which should you pick?
Direct answer: pick free skills if you want to read and edit the method yourself; they are public, versioned on GitHub and easy to audit. Paid packs make sense when you want many ready-made skills in one download and accept that you cannot see the contents before buying.
| Option | Cost | Sales-page depth | Can you read it before installing? | Install |
|---|---|---|---|---|
| marketingskills | Free | High (copywriting, cro, offers) | Yes | npx skills add |
| ClawFu sales-letter-writer | Free | High (long-form letter) | Yes | git clone + copy |
| Sales-Page-Copywriting-Skill | Free | Medium (section + hostile review) | Yes | npx skills add |
| Anthropic marketing plugin | Free | Medium (drafting + claim review) | Yes | plugin marketplace |
| alirezarezvani marketing | Free | Medium | Yes | plugin marketplace |
| humanizer | Free | Final pass only | Yes | plugin or npx skills add |
| Inflectual bundle | $167 | Pricing public; sales depth unconfirmed | No | ZIP |
| Contra SEO & AEO pack | $39 | Low (SEO focus) | No | ZIP |
| SuperSkills | $50 | Unconfirmed | No | ZIP |
A practical point people raise on forums: skills are plain text. A paid pack does not run better than a free one; what you pay for is curation and someone else’s writing time. If you can write a decent brief, you can also write your own skill. Build your own Claude Code skill in an afternoon and encode your own offer and guarantee rules.
Takeaway: the deciding question is control. If you want to audit every rule the model follows, stay free.
How a sales page skill should handle long-form structure
Direct answer: a long-form sales letter skill should lay out the sections in a fixed order, give each section a job and an exit test, and stop Claude from moving on until the current section does its job. PAS and AIDA are the two frameworks most skills build in.
PAS and AIDA, built into a skill
PAS (Problem, Agitate, Solution) works for the opening third of the page. Name the problem in the reader’s words, show what it costs them, then introduce the solution.
AIDA (Attention, Interest, Desire, Action) works as the whole-page skeleton. The headline grabs attention, the story and mechanism hold interest, the offer and proof build desire, and the close asks for action.
In a SKILL.md, these become step lists rather than vague advice. A minimal pattern:
## Workflow
1. Ask for: product, one target reader, the top 3 objections, real proof assets, guarantee terms, any real deadline.
2. Lead: write 3 headlines for one reader and one promise (AIDA: Attention).
3. Opening: PAS. Problem in the reader's words, honest cost, then the solution.
4. Mechanism: explain why this works where alternatives failed (Interest).
5. Proof: use only supplied proof. If none, write [PROOF NEEDED: type].
6. Offer stack and price anchor using real prices only (Desire).
7. Objections: one H3 per objection, answered with facts.
8. Guarantee: restate the exact supplied terms. Never invent terms.
9. Urgency: only from a supplied real deadline. Otherwise omit.
10. Close: one call to action (Action).Section order for a long-form letter
- Pre-headline naming the reader
- Headline and subhead
- Lead story or problem statement
- Agitation (cost of doing nothing)
- The mechanism or “why this is different”
- Proof
- What you get (offer stack)
- Price and comparison
- Objections and FAQ
- Guarantee
- Deadline, only if real
- Close and P.S.
ClawFu’s sales-letter-writer follows a Halbert and Kennedy style. Corey Haines’ copywriting and cro skills lean toward modern landing page order. For short pages see skills for landing page copy, and for the headline step see headline skills.
Takeaway: a framework only helps if the skill makes it a sequence with inputs. “Use AIDA” alone changes nothing.
Offers, objections and guarantees: what to look for
Direct answer: for offers, the skill should ask what the buyer actually gets and price it honestly. For objections, it should collect real objections first and answer each one. For guarantees, it should only restate terms you give it. If a skill writes a guarantee you did not supply, remove that rule.
Offers
An offer is more than the price. It is the deliverable, the bonuses, the terms and the risk reversal together. ClawFu’s grand-slam-offers and Corey Haines’ offers and pricing skills both cover offer construction. Check that the skill asks you for the real components and does not inflate “value” figures. A line like “$5,000 of value” needs a basis you can defend; otherwise cut it.
Objections
The strongest pattern here is the hostile-reader pass in the yashaiguy-dev skill: write a draft, then attack it as a skeptical buyer. ClawFu’s objection-mapping gives you a list to work from. Better still, feed the skill real objections from sales calls, support tickets or Reddit threads in your niche. A skill can only answer the objections it is given.
Common sales page objections to supply:
- “Is this worth the price?”
- “Will this work for my situation?”
- “I tried something like this and it failed.”
- “What happens if I do not like it?”
- “Why buy now and not later?”
Guarantees
A guarantee is a promise with legal weight. The skill should restate your exact terms (length, what qualifies, how to claim) and nothing more. Write that as a hard rule in the SKILL.md: “Guarantee text must match the supplied terms word for word in substance. If no terms are supplied, write [GUARANTEE TERMS NEEDED].”
Takeaway: every one of these three sections depends on facts only you have. A skill that asks for them is doing its job.
Honest urgency and the FTC rules on fake reviews
Direct answer: in the US, the FTC’s rule on consumer reviews and testimonials (16 CFR Part 465), announced 14 August 2024 and in effect from 21 October 2024, bans fake reviews and testimonials, including ones generated by AI. The FTC can seek civil penalties per violation. Separately, FTC guidance treats fake countdown timers and false scarcity claims as deceptive design.
What the review and testimonial rule covers
Per the FTC press release, the rule prohibits:
- Writing, buying or selling fake reviews or testimonials, including AI-generated ones
- Paying for or incentivising reviews conditioned on them being positive or negative
- Undisclosed reviews from company insiders
- Suppressing negative reviews through threats or intimidation
- Buying or selling fake social media indicators such as bot followers or views
At announcement, legal commentators cited a maximum of $51,744 per violation. That figure is inflation-adjusted each year, so check the current number with the FTC.
This is why the claim rules in your skill matter. An AI model asked to “add social proof” will happily write “This changed my business! - Mike R.” That sentence is a fake testimonial the moment you publish it.
Urgency that stays honest
The FTC’s 2022 staff report on dark patterns, Bringing Dark Patterns to Light, names fake countdown timers and false “low stock” or “high demand” messages as deceptive. Honest urgency comes from real clocks:
| Honest urgency | Fake urgency (do not use) |
|---|---|
| Launch price ends on a stated date, and actually ends | Timer that resets on reload |
| Cohort starts on a fixed date | ”Only 3 spots left” with no real limit |
| Bonus tied to a real event | ”Limited time” with no end date |
| Seasonal deadline the buyer already knows | Fake “X people are viewing this” |
Rules to paste into any sales page skill
## Claim rules (non-negotiable)
- Never write testimonials, reviews, ratings, user counts or results. Use [PROOF NEEDED: ...].
- Never write a deadline, countdown or scarcity claim unless a real one is supplied.
- Never state a guarantee beyond the supplied terms.
- Never invent statistics or conversion figures.This is not legal advice. If you sell in regulated categories (health, finance, income claims), have the page checked.
Takeaway: the cheapest compliance step is a four-line rule block in your SKILL.md.
A worked setup: from install to first draft
Direct answer: install one structure skill, one review skill and one humanizer, give Claude a brief with real proof and terms, then run draft, hostile review, claim check and humanize in that order.
This is a suggested workflow, not a tested benchmark.
- Install.
npx skills add coreyhaines31/marketingskills --skill copywriting offers cro -a claude-code, copy ClawFu’ssales-letter-writerinto~/.claude/skills/, and add humanizer. - Write a brief file (
brief.md) with: product, one reader, price, offer components, guarantee terms, any real deadline, real testimonials with permission, and the top objections. - Draft. Ask Claude: “Using sales-letter-writer, write a long-form sales page from brief.md. Follow the claim rules.”
- Attack it. Run the hostile-reader pass from the Sales-Page-Copywriting-Skill, or ask Claude to read the draft as a skeptical buyer and list every unanswered objection.
- Check claims. Run Anthropic’s
brand-reviewto flag unsupported claims. Then search the draft for every number and quote and confirm each one is in your brief. - Edit and humanize. Use
copy-editing, then the humanizer. See editing skills. - Carry it into email. The same brief feeds launch emails (email marketing skills) and ads (ad copy skills).
Brief checklist
- One named target reader
- Real price and offer components
- Exact guarantee terms
- Real deadline, or “none”
- Real proof with permission, or “none yet”
- Top five objections in the buyer’s words
Takeaway: the brief does most of the work. Skills only arrange what you give them.
Common mistakes with AI sales page skills
Direct answer: the most common mistakes are installing too many overlapping skills, giving no real proof, letting the model write testimonials, using urgency with no real deadline, and publishing without a human read.
- Overlap. Five copywriting skills with similar descriptions compete for the same request. Install one structure skill per job.
- Empty brief. No proof in, invented proof out. Supply it or demand placeholders.
- Template testimonials left in. Any “social proof template” must be replaced or deleted before publishing.
- Borrowed urgency. Do not copy the “limited time” banner style of the packs you buy from.
- Inflated value stacks. “$2,997 value” for a bundle of PDFs erodes trust and may count as a misleading price claim.
- Skipping the read-aloud. Read the page out loud once. Clumsy lines show up fast.
- Never updating the skill. When a guarantee or price changes, change the skill and the brief, or the old terms will keep coming back.
Takeaway: most failures come from inputs and checks, not from the skill itself.
Frequently asked questions
What is the best Claude Code skill for sales pages?
For free, Corey Haines’ marketingskills (copywriting, cro, offers) plus ClawFu’s sales-letter-writer cover short and long pages. Add a humanizer for the final pass.
Are Claude Code skills free?
Most are. The repos in this guide are free on GitHub. Paid packs exist on Gumroad, Contra and seller sites, priced from $39 to $167 in our check.
How do I install a Claude Code skill?
Put the skill folder in ~/.claude/skills/ or .claude/skills/, run npx skills add owner/repo, or add a plugin marketplace with /plugin marketplace add. Restart Claude Code if it does not appear.
Can Claude write a full long-form sales letter?
Yes, given a detailed brief. A skill like sales-letter-writer keeps the structure consistent, but you still supply proof, terms and the human edit.
Is PAS or AIDA better for a sales page?
They do different jobs. PAS suits the opening; AIDA suits the full page. Most long-form skills use both.
Can AI write testimonials for my sales page?
No. Under the FTC rule, AI-generated fake testimonials are banned. AI can format or trim real testimonials you have permission to use.
Is fake urgency illegal?
FTC staff guidance treats fake countdown timers and false scarcity as deceptive design, and the FTC can act against deceptive practices. Use real deadlines only.
What should a sales page guarantee say?
Exactly the terms you will honor: duration, conditions and how to claim. Never let a model add terms.
Do paid Claude skill packs write better sales pages?
Unconfirmed. Skills are plain text instructions, and none of the paid packs we checked is built mainly for sales pages.
Where do Claude Code skills live on my computer?
Personal skills live in ~/.claude/skills/; project skills in .claude/skills/ inside the repo. Plugin skills are managed by Claude Code.
Why is my skill not triggering?
The description in the SKILL.md frontmatter decides when Claude loads it. Make it name the task (“long-form sales page”) and remove overlapping skills.
Can I use these skills in Claude.ai instead of Claude Code?
SKILL.md skills also work in Claude apps that support skill uploads, though install steps differ. This guide covers Claude Code.
How do I stop Claude from inventing statistics?
Add a claim rule to the skill: no numbers unless supplied, and use [PROOF NEEDED] placeholders. Then check every number in the draft.
Is a sales page different from a landing page?
A sales page is usually long-form and sells directly. A landing page is often shorter and aims at one action such as a signup. See the landing page skills guide.
Do I need coding skills to use Claude Code skills?
Not much. You run a few terminal commands and edit Markdown files. See Claude Code skills for copywriters.
