WHAT IT DOES

WHY IT NEEDS A POLICY

Why bulk_assign_category needs a policy

This tool creates or modifies data (category assignments) in a reversible manner. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely retrieve data (Read). Severity is medium because bulk modification of game library metadata could cause organizational confusion or require manual cleanup if misused, but the operation is reversible.

From the tool's definition Tool name 'bulk_assign_category' and description 'Assign multiple games to a category at once' indicate modification of game metadata. The 'bulk' prefix suggests batch operations affecting multiple records.
