WHY IT NEEDS A POLICY

Why create_category needs a policy

This tool creates a new category entry in the Lutris gaming library database. Category creation is a reversible write operation—new categories can be deleted or modified without permanent data loss. There is no code execution, financial impact, or destructive action. The blast radius is minimal since it only adds metadata to organize games, not affecting game files or system state.

From the tool's definition Tool name 'create_category' and description 'Create a new game category' indicate data creation. The server description confirms it enables 'modifying game details, organizing categories' through a SQLite database, making this a reversible write operation.
