What get_validations does on Shopify Graphql
AI agents call get_validations to retrieve information from Shopify Graphql without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_validations is rated Low
This tool retrieves validation rules for carts and checkouts—a read-only operation with no side effects. It does not create, modify, or delete data, nor does it execute code or trigger financial transactions. The low severity reflects minimal blast radius; misuse would only expose validation logic information, not compromise transactions or data integrity.
From the tool's definition Tool name 'get_validations' and description 'Fetch cart and checkout validation rules' indicate a retrieval operation that queries validation rules without modifying, deleting, or executing external operations.
