Customer tools require Shopify's Protected Customer Data approval (requested when we submit to the App Store). Idempotency: each tool call is billed once per UTC hour per store — duplicate calls in the same hour are free. Cap enforcement: when your usage reaches 95% of the cap, Claude stops making tool calls until you raise the cap or a new period starts.
