WHY IT NEEDS A POLICY

Why collection_share needs a policy

This tool modifies the sharing/visibility settings of a collection — either granting access to specific users or making it publicly accessible. This is a reversible write operation (sharing can be revoked), but misuse could inadvertently expose private bookmark collections to unintended parties, warranting medium severity.
