What disable_gift_card does on Shopify Graphql
AI agents use disable_gift_card to create or update resources in Shopify Graphql, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.
Why disable_gift_card is rated Medium
Disabling a gift card is a reversible modification of data state. It changes the card's availability/functionality but the card record and its value remain intact and can be re-enabled. This is characteristic of Write operations.
From the tool's definition Tool description states 'Disable a gift card'. The action modifies the state of a gift card (from enabled to disabled) but does not irreversibly delete it or move money. The tool is on a Shopify Admin GraphQL server enabling store management.

disable_gift_card stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Shopify Graphql, apply this rule, and every disable_gift_card call is checked against it from then on.
