WHY IT NEEDS A POLICY

Why fizzy_publish_board needs a policy

Severity is medium because publishing sensitive project information could expose confidential business data, but the action itself is not destructive or irreversible.

From the tool's definition Tool description states 'Publish a Fizzy board, making it publicly accessible via a shareable link' — this changes the visibility/access control state of existing data, a reversible modification.
