validate_graphql_codeblocks

Validate GraphQL code blocks against the Shopify GraphQL schema to detect and correct hallucinated fields or operations. Provides detailed validation results to guide LLMs in generating accurate and error-free code snippets.

Instructions

This tool validates GraphQL code blocks against the Shopify GraphQL schema to ensure they don't contain hallucinated fields or operations. If a user asks for an LLM to generate a GraphQL operation, this tool should always be used to ensure valid code was generated.

It returns a comprehensive validation result with details for each code block explaining why it was valid or invalid. This detail is provided so LLMs know how to modify code snippets to remove errors.
