WHY IT NEEDS A POLICY

Why create_phone_qrcode needs a policy

This tool creates a new QR code object stored via the QR Forge API. It is a reversible write operation (the QR code can be deleted later). It does not execute code, delete data, or move money. Severity is low because a static phone-dial QR code has minimal blast radius — it encodes a phone number but does not initiate a call or financial transaction on its own.

From the tool's definition 'Create a phone-number QR code (static; dials when scanned)' — creates a new QR code resource via the API
