## What it does

This skill guides coding agents through building Saleor integrations via GraphQL and webhooks. While the core communication protocol works with any backend stack, the included patterns rely on Next.js examples built with `@saleor/app-sdk`.

Instructions are structured across prioritized categories. The skill covers the initial registration handshake, signature verification, and synchronous or asynchronous webhook lifecycles. It also outlines rules for payment processing with the Transaction API, domain-scoped settings persistence via `EncryptedMetadataManager`, and UI synchronization through AppBridge.

Without verifying user JWT tokens on every route, iframe-embedded apps expose administrative actions. The guide enforces strict scope separation between app-level tokens and dashboard user sessions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add saleor/agent-skills --skill saleor-app -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add saleor/agent-skills --skill saleor-app -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add saleor/agent-skills --skill saleor-app -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install saleor/agent-skills saleor-app
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add saleor/agent-skills --skill saleor-app -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/saleor/agent-skills --path skills/saleor-app
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add saleor/agent-skills --skill saleor-app -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/saleor/agent-skills/tree/HEAD/skills/saleor-app/SKILL.md

## When to use it
- configure an app manifest with required webhook subscriptions
- verify Saleor webhook signatures and handle asynchronous event retries
- implement payment flows using the Transaction API and provider events
- embed custom interfaces into the Saleor Dashboard with AppBridge

## Example prompts
- Write a Saleor app manifest registering order creation and payment webhooks
- Implement webhook signature verification using `@saleor/app-sdk` in Next.js
- Set up domain settings storage with `EncryptedMetadataManager`

# Saleor App

Guide for building apps that extend Saleor via webhooks and the GraphQL API.
Framework-agnostic protocol documentation with Next.js examples using `@saleor/app-sdk`.

## When to Apply

- Defining an app manifest or registering webhooks
- Handling async/sync webhook events from Saleor
- Building payment apps with the Transaction API and provider webhooks
- Authenticating requests (registration handshake, JWT, signature verification)
- Storing app settings in Saleor metadata
- Building Dashboard UI inside the iframe
- Making GraphQL calls with app tokens
- Debugging webhook failures, auth errors, or permission issues
- Deciding who can view the app and what they should see (user vs app scope)

## Rule Categories by Priority

| Priority | Category        | Impact   | Prefix          |
| -------- | --------------- | -------- | --------------- |
| 1        | Protocol        | CRITICAL | `protocol-`     |
| 2        | Permissions     | CRITICAL | `permissions-`  |
| 3        | Payment Apps    | CRITICAL | `payment-`      |
| 4        | Webhooks        | HIGH     | `webhook-`      |
| 5        | Data & Settings | HIGH     | `data-`         |
| 6        | Dashboard UI    | MEDIUM   | `dashboard-`    |
| 7        | Development     | MEDIUM   | `dev-`          |

## Quick Reference

### 1. Protocol (CRITICAL)

- `protocol-manifest` — App manifest, required endpoints, permissions, extensions
- `protocol-auth` — Registration handshake, APL, token scopes, JWT/signature verification

### 2. Permissions (CRITICAL)

- `permissions-access-scopes` — Define per-feature permissions; guard user JWT on every API route; baseline + per-route meta; UI mirrors server

### 3. Payment Apps (CRITICAL)

- `payment-app` — Financial truth, stable references, unknown outcomes, refunds, and reconciliation

### 4. Webhooks (HIGH)

- `webhook-async` — Async event handling, payload typing, retry policy, signature verification
- `webhook-sync` — Sync event handling, response schemas, performance constraints
- `webhook-external` — Receiving webhooks from external services, multi-tenant routing

### 5. Data & Settings (HIGH)

- `data-graphql` — GraphQL from apps: client setup, auth headers, codegen, app vs user tokens
- `data-settings` — MetadataManager, EncryptedMetadataManager, domain-scoped persistence

### 6. Dashboard UI (MEDIUM)

- `dashboard-appbridge` — AppBridge iframe protocol, actions, events, theme/locale sync

### 7. Development (MEDIUM)

- `dev-debug` — Common errors, webhook dry runs, tunnel setup, debugging checklist
