Chargeback response kit for Shopify

A merchant posted this on the Shopify Community forum (store details removed). The order was a local hand delivery. The chargeback reason was Fraudulent. The merchant had a text thread ("yes great, leave them outside the door if we are not home…") and a photo of the parcel at the door.

Before. The merchant submitted the texts and the photo as proof of delivery, and lost. Delivery proof doesn't answer a fraud claim. The bank wants to know whether the cardholder authorised the payment.

After. The skill's first lines:

Verdict: Weak (fight only if it's cheap to do).
Your texts and delivery photo are good evidence that the person you were dealing with ordered and accepted the goods. That is not the same as showing the cardholder authorized the charge, and that is what a Fraudulent dispute turns on. […] The case moves up to Fight if the order page shows any of these:

• AVS and CVV both matched.
• 3D Secure was used.
• The billing address equals the address you delivered to.
• The IP or device matches his location.
• He has earlier undisputed orders on the same card.
• The phone number or email he texted from is the one on the order.

The response the skill drafts leads with an Authorization section. It's built only from items the merchant can verify, and anything that can't be backed up is marked for deletion.

• Fraudulent or unrecognized
• Product not received
• Product unacceptable or not as described
• Subscription canceled
• Duplicate
• Credit not processed
• Also covered: General, inquiries, Shopify Protect orders and orders that were already refunded.

The download holds 6 fill-in response letters with checklists (Word .docx files, which open in Google Docs), 6 worked examples and a Start-here PDF, one letter for each reason below. It also has a Word note, 7-USING-WITH-PAYPAL-STRIPE-KLARNA, for customers who paid with PayPal, Stripe or Klarna. Counted from the real file.

One price, $5. No percentage of what you win, no subscription, no surprise charges.

Stuck? Email your filled-in letter to kaiventura.founder@gmail.com before you submit (remove card numbers and anything you don't want to share). We'll tell you what's missing for your reason, usually within one working day. Not legal advice.

Got a chargeback on Shopify Payments? Paste the dispute and say what evidence you have. This skill:

• tells you honestly whether to fight, whether the case is weak, or whether to accept (with the money maths)
• writes a response matched to the dispute reason, ready to paste into Shopify's chargeback response page
• gives you a checklist of which files to attach, where, and in what format
• lists the evidence you're missing and how to get it

Not using an AI assistant? The templates/ folder has fill-in response letters for six reasons (Word / Google Docs) with evidence checklists and worked examples. Open templates/START-HERE.pdf first. templates/7-USING-WITH-PAYPAL-STRIPE-KLARNA.docx covers customers who paid with PayPal, Stripe or Klarna.

Stuck? Email your filled-in letter before you submit (the address is on templates/START-HERE.pdf). Remove card numbers and anything you don't want to share. We'll tell you what's missing for your reason, usually within one working day. Not legal advice.

It never invents evidence. Anything you didn't tell it shows up as a gap or a [CONFIRM] marker, not as a fact. That includes the form of the evidence: if you say "she told me it was a mistake" without saying how, the response won't claim you have it in writing.

Works for: Fraudulent, Unrecognized, Product not received, Product unacceptable / not as described, Subscription canceled, Duplicate, Credit not processed, General. Also handles inquiries, Shopify Protect orders and already-refunded orders. Built from Shopify Help Center and Stripe dispute documentation (October 2026).

Tested on 6 real dispute scenarios from the Shopify Community forum. Every final run scored 9/10 or more, with no invented evidence.

Tested on 5 real dispute scenarios from the Shopify Community forum:

• product not received with delivered tracking
• fraud with hand delivery
• subscription cancelled with two subscriptions
• an unshipped order flagged as fraud
• product unacceptable with no customer contact

Final version: 9/10 on every test, and no invented evidence in any run. The test logs are kept internally.

Update 2026-10-04: the skill no longer states how or when something was said unless you said it (no "in writing", "by email" or exhibit number for a statement you only described), and nothing it marked as "confirm" or "get it in writing" can appear in the response as evidence you hold. Re-tested on a sixth scenario (a customer who says she withdrew the dispute, two runs) and re-run on the first two scenarios above: 9, 9, 10 and 9 out of 10, with no invented or stretched evidence.

The tests ran on real public data, never made-up cases, and were scored against a written rubric. A skill in this range ships only when every test scores 8/10 or more.

How we test, what we do not do, and which assistants we ran it on.

It won't:

• Promise a win. The cardholder's bank decides.
• Write a fake or "improved" tracking update, message, signature or policy.
• Give legal advice.

Works with any assistant that reads SKILL.md skills (Claude, Codex, Gemini CLI, Cursor and others), plus a paste-in prompt version for ChatGPT or any chatbot. We run our release tests on Claude Sonnet and Opus. Use your assistant's strongest model: in our tests, a small, fast model added facts that were not in the source data. This skill has no scripts and needs no web access: it works from what you paste.

1. Unzip the download. It holds the chargeback-response-writer folder, ready-made zips for claude.ai in a claude-ai folder, a README and the licence.
2. Put the chargeback-response-writer folder where your assistant looks for skills. The generic path is .agents/skills/ (or npx skills add from a folder). Tool-specific paths:
   • Claude Code: ~/.claude/skills/ (or .claude/skills/ inside one project)
   • OpenAI Codex, Gemini CLI, Cursor and others: .agents/skills/ or the skills folder their docs name
   • claude.ai: Customize, Skills, then the plus button, Create skill, Upload a skill, and upload the zip from the claude-ai folder without unzipping it (code execution must be on in Settings, Capabilities)
   • ChatGPT or any chatbot: open the skill's prompt.md, paste it into the chat, then paste your own text or link
   • Steps for each tool, with links to its official docs: how to install Agent Skills
3. Ask for the job in plain words, for example: "I got a chargeback, reason Fraudulent, $450. Here is the order and the evidence I have: ...". The skill loads by itself.
