WHAT IT DOES

WHY IT NEEDS A POLICY

Why fizzy_publish_board needs a policy

Publishing a board is a reversible modification of data state (access permissions/visibility) rather than creation, deletion, or code execution. It changes who can access the board but does not destroy data or execute arbitrary operations. The severity is medium because publishing could expose sensitive task information unintentionally, but the action is reversible (can unpublish).

From the tool's definition The tool description states it 'Publish a Fizzy board, making it publicly accessible via a shareable link.' This is a state-changing operation that modifies access permissions and visibility of a board, converting it from private/restricted to public.
