WHY IT NEEDS A POLICY

Why adjust_crop_position needs a policy

Based on the tool name, this tool likely adjusts/modifies the crop position of an image processing profile in RawTherapee, which is a reversible write operation. However, the empty description significantly lowers confidence. Given the server context (RAW photo development with iterative editing), this is most likely a Write operation that modifies image processing parameters.

From the tool's definition Tool name 'adjust_crop_position' suggests modifying crop parameters; description is empty and uninformative.
