WHY IT NEEDS A POLICY

Why add_localized_news needs a policy

This tool creates new news content in the PlayFab system, which is a reversible write operation. It does not delete, execute arbitrary code, or move financial resources. The 'medium' severity reflects that news content creation could be used to spread misinformation to players, but the impact is limited to content modification rather than account/financial harm or system-level code execution.

From the tool's definition Tool name 'add_localized_news' and description 'Creates news' indicate data creation. The phrase 'Automatically handles the base news creation and localization' confirms a write operation that modifies the PlayFab content system by adding new news entries.
