WHY IT NEEDS A POLICY

Why image_apply_filters needs a policy

This tool modifies image files by applying visual filters and adjustments. These modifications are reversible (the original image can be reprocessed or restored), and there is no data deletion, code execution, or financial impact. The changes are local to image properties (pixel values, color data) rather than destructive alterations.

From the tool's definition Tool applies filters and effects to images (blur, sharpen, grayscale, sepia, brightness, contrast, saturation adjustments), which modifies image data. The description states 'Apply filters and effects to image,' indicating data transformation.
