WHY IT NEEDS A POLICY

Why strings_create_translation needs a policy

This tool creates new translation entries in a localization system, which is a reversible write operation. The blast radius is medium because an agent could create incorrect or malicious translations that affect application content and user experience, but the action is reversible (translations can be updated or deleted). It does not delete data (Destructive), execute code (Execute), or move money (Financial).

From the tool's definition Tool name is 'strings_create_translation' and description states 'Create a translation for a key and locale in a Phrase Strings project.' The verb 'Create' indicates data modification.
