## What it does

The skill sets boundaries for how the agent handles Stripe: payments run on the server, secret keys stay out of client code, webhooks get signature verification. It ships TypeScript examples — client setup, a Payment Intent route in `app/api/create-payment-intent/route.ts`, Stripe Elements wired through `loadStripe` and `Elements`, and a checkout form using `PaymentElement` with `confirmPayment`.

Subscriptions and customers get their own sections: creating a subscription with `payment_behavior: 'default_incomplete'`, cancelling one, and looking up an existing customer by email before creating a duplicate. The webhook handler in `app/api/webhooks/stripe/route.ts` switches on `payment_intent.succeeded`, `customer.subscription.created`, `customer.subscription.deleted` and `invoice.payment_failed`.

You need `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET` and `NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY` in your environment. Leak the secret key to the browser and you have a real incident, not a style issue. The examples pin API version `2023-10-16`, so behaviour can shift if you upgrade Stripe.

## Requirements
- Works with: Stripe

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill stripe -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/stripe/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/stripe/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill stripe -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/stripe/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill stripe -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/stripe/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Mindrally/skills stripe
```

2. **Manually: put the files in place**
- File: `.github/skills/stripe/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill stripe -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Mindrally/skills --path stripe
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/stripe/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Mindrally/skills --skill stripe -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Mindrally/skills/tree/HEAD/stripe/SKILL.md

## When to use it
- accept card payments in Next.js without exposing the secret key
- create a Payment Intent and return the clientSecret
- wire up Stripe Elements and a checkout form
- start a subscription with an incomplete payment and save the card
- verify a webhook signature and route events by type

## Example prompts
- add Stripe checkout to this Next.js app: a server route for the Payment Intent and a PaymentElement form
- create a Stripe subscription with payment_behavior default_incomplete and save the payment method
- write a Stripe webhook that verifies the signature and handles payment_intent.succeeded

# Stripe Integration

You are an expert in Stripe payment integration, TypeScript, React, and Next.js for building secure payment solutions.

## Core Principles

- Always handle payments on the server side
- Use Stripe's latest API version
- Implement proper error handling
- Follow PCI compliance best practices
- Use webhooks for reliable event handling

## Server-Side Setup

### Stripe Client Configuration

```typescript
import Stripe from 'stripe';

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!, {
  apiVersion: '2023-10-16',
  typescript: true,
});
```

### Create Payment Intent

```typescript
// app/api/create-payment-intent/route.ts
import { NextResponse } from 'next/server';
import Stripe from 'stripe';

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);

export async function POST(request: Request) {
  try {
    const { amount, currency = 'usd' } = await request.json();

    const paymentIntent = await stripe.paymentIntents.create({
      amount,
      currency,
      automatic_payment_methods: { enabled: true },
    });

    return NextResponse.json({
      clientSecret: paymentIntent.client_secret,
    });
  } catch (error) {
    return NextResponse.json(
      { error: 'Payment intent creation failed' },
      { status: 500 }
    );
  }
}
```

## Client-Side Integration

### Stripe Elements Setup

```typescript
'use client';

import { Elements } from '@stripe/react-stripe-js';
import { loadStripe } from '@stripe/stripe-js';

const stripePromise = loadStripe(process.env.NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY!);

export function StripeProvider({ children }: { children: React.ReactNode }) {
  return (
    <Elements stripe={stripePromise}>
      {children}
    </Elements>
  );
}
```

### Payment Form Component

```typescript
'use client';

import { useState } from 'react';
import {
  PaymentElement,
  useStripe,
  useElements,
} from '@stripe/react-stripe-js';

export function CheckoutForm() {
  const stripe = useStripe();
  const elements = useElements();
  const [isLoading, setIsLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();

    if (!stripe || !elements) return;

    setIsLoading(true);
    setError(null);

    const { error: submitError } = await stripe.confirmPayment({
      elements,
      confirmParams: {
````
