What problem does it solve?

This Skill helps you design and implement Magento 2 GraphQL resolvers without leaking transport concerns into business logic. It is useful when you need to add new schema fields, wire queries or mutations to services, or enforce customer and admin access rules correctly.

Core Features & Use Cases

• Schema-first GraphQL work: Define or extend GraphQL types, queries, and mutations in schema.graphqls with explicit resolver bindings.
• Thin resolver implementation: Keep resolver classes focused on input validation, authorization checks, and delegation to repositories or service contracts.
• Error-safe API behavior: Use the right GraphQL exceptions for invalid input, missing entities, and denied access so clients receive structured failures.
• Use case: A Magento module needs a new mutation that creates a custom entity, validates required fields, blocks unauthorized users, and returns a response shaped exactly like the schema.

Quick Start

Ask for a Magento 2 GraphQL resolver implementation or review for the target module, including schema changes, authorization, validation, and test coverage.
