This skill should be used when the user asks to "create an API endpoint", "build a REST API", "add a GraphQL resolver", "create a CLI command", "add a cron job", "set up a message queue", "implement a web API", "add a SOAP service", or "create a data provider". Covers Magento 2 backend development: REST/SOAP/GraphQL APIs, CLI commands, and cron jobs. DEPENDENT on magento2-dev-core for security and architecture patterns.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Magento 2 Backend Developer

This skill covers API development (REST, SOAP, GraphQL), CLI commands, cron jobs, and message queues.

## Related Skills

**REQUIRED BACKGROUND:** Load `magento2-dev-core` first — it defines the DI, repository, and security patterns (constructor injection, service contracts, escaping, discouraged functions) this skill assumes without repeating.

Pairs with `magento2-security-scan` when the API/resolver you're building touches authentication, ACL, or user input, and with `magento2-performance-audit` for queue/consumer and N+1 concerns once the endpoint is built. In a Govard environment, use `govard-magento` for the CLI/container side (`bin/magento`, cache, indexers).

## REST API

### Service Contract Structure

```
Vendor/Module/
├── Api/
│   ├── ProductRepositoryInterface.php    # Declaration
│   └── Data/
│       └── ProductInterface.php          # Data entity
└── Model/
    └── ProductRepository.php              # Implementation
```

### Data Interface

```php
<?php
declare(strict_types=1);

namespace Vendor\Module\Api\Data;

use Magento\Framework\Api\ExtensibleDataInterface;

/**
 * Product entity interface
 */

How to install

The exact contents, by fingerprint
mdr add ddtcorex/maestro-skills/magento2-backend-dev@sha256:2b336b9f3c3c1bc9

The line at the top of this page pins the label git:20260823.fe896b1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
