WHY IT NEEDS A POLICY

Why generate_event_qr needs a policy

This tool creates new data artifacts (QR code images encoding calendar event information). Generation of static content like QR codes is a reversible write operation. No code execution, data deletion, or financial impact is involved. The severity is low because misuse would at worst create unwanted QR codes, which have minimal blast radius.

From the tool's definition Tool generates/creates QR codes (evidenced by 'generate_event_qr' name and description 'Generate a QR code for calendar event'). The action is reversible—QR codes can be regenerated or deleted without lasting harm.
