WHY IT NEEDS A POLICY

Why karea_share_project needs a policy

Sharing a project modifies project metadata and access permissions reversibly—the share can be undone. This is a write operation rather than read (queries data only), execute (runs code/commands), destructive (irreversible deletion), or financial (money movement).

From the tool's definition Tool name 'karea_share_project' and description 'Share a project with another user' indicate modification of project access permissions, which is a write operation that creates or modifies data (access control list entries).
