WPGraphQL Schema Extension Builder
Builds and documents WPGraphQL extensions with hooks such as `graphql_register_types`, `register_graphql_field`, and `register_graphql_object_type`. Ideal for exposing custom fields, computed properties, and relationships in a way that stays aligned with WordPress data models and client queries.

WPGraphQL Schema Extension Builder is designed for developers who need to extend a WordPress site beyond the default GraphQL schema without creating brittle one-off snippets. The skill centers on real WPGraphQL APIs including graphql_register_types, register_graphql_field, register_graphql_object_type, and resolver callbacks that map WordPress objects into queryable GraphQL fields. It is especially helpful when a frontend needs normalized data that is not exposed cleanly through the default schema.
What this skill actually does
The workflow usually starts by identifying a custom post type, taxonomy, or meta field that needs to be queryable. From there, the skill can define field arguments, shape output types, and document the expected query patterns so consumers in Next.js, Apollo, or custom clients know exactly what to request. It also helps keep naming, nullability, and relationship handling consistent, which matters once a schema starts growing across teams.
Use this skill when building headless WordPress projects, tightening schema contracts, or exposing computed data in WPGraphQL without making the API harder to reason about.
