WHY IT NEEDS A POLICY

Why generate_and_save_qrcode needs a policy

This tool creates or modifies data (PNG files) in a reversible manner, fitting the Write category. While it does perform file I/O, there is no code execution, deletion, or financial impact. Severity is low because QR code generation and file creation have minimal blast radius—worst case is disk space consumption or benign PNG files that can be easily removed.

From the tool's definition Tool description states it will 'automatically save as PNG file to specified directory', which creates files on the filesystem. The action is reversible (files can be deleted) and has no destructive or side-effectful operations like code execution.
