WHY IT NEEDS A POLICY

Why todoist_invitation_reject needs a policy

The tool modifies data (invitation status) but the action is reversible—a rejected invitation can typically be re-sent or the sharing can be re-configured. This qualifies as Write rather than Destructive. Severity is medium because rejecting an invitation could disrupt collaboration workflows, but the blast radius is limited to project access management without data loss or financial impact.

From the tool's definition Tool performs 'Reject a project sharing invitation' - this modifies the state of an invitation record by changing it from pending to rejected, which is a reversible write operation.
