GraphQL queries accept variables declared in the query signature and bound in the request. Define variables with the $ prefix (e.g., $userId: ID!), reference them in your query, and pass values separately from the query string. This approach decouples query structure from runtime data, enabling reuse across client applications.

GraphQL mutations follow the same syntax as queries but use the mutation keyword and typically modify server state. Structure mutations with input variables, specify the fields to return, and use fragments to reuse selection sets across multiple mutations. Mutations execute sequentially and support the same variable binding as queries.

Yes, GraphQL fragments let you define reusable selection sets once and include them in multiple queries and mutations. Fragments reduce duplication, improve maintainability, and ensure consistent field selection. Use the spread operator (...fragmentName) to inline fragment definitions into your requests.

Validate syntax by checking query structure against the GraphQL schema—ensure fields exist, types match, and required arguments are supplied. Most GraphQL clients and testing tools provide syntax validation; this Skill integrates validation into script generation to catch errors before deployment.

Use nested selections to fetch related objects in a single request; specify fields at each depth level to avoid over-fetching. Combine nested selections with fragments for complex hierarchies, and leverage aliases to rename fields if needed. This approach reduces round trips and aligns client needs with backend schema.

Testing queries in isolation via a GraphQL client or explorer before integrating them into your application catches schema mismatches and logic errors early. This Skill provides ready-to-use query templates and generates script artifacts that support standalone validation and testing workflows.
