WHY IT NEEDS A POLICY

Why create_email_qrcode needs a policy

This tool creates a new QR code resource, which is a reversible write operation. The QR code itself is static metadata (containing an email address to be used in a prefilled email) with no financial impact, no code execution, and no destructive capability. Misuse would result in creation of unwanted QR codes, which can be deleted (delete_qrcode exists as a sibling tool), making this a low-severity write operation.

From the tool's definition Tool name is 'create_email_qrcode' and description states it 'Create[s] an email QR code'. The verb 'create' combined with the action of generating a new QR code resource indicates a write operation that adds data to the system.
