WHY IT NEEDS A POLICY

Why text_to_audio needs a policy

This tool creates new audio content from text input using an external API. It produces/writes a new artifact (audio file) but does not delete data, execute arbitrary code, or involve financial transactions. It is reversible in the sense that the generated file can be discarded. Misuse could result in unwanted API usage or content generation, hence medium severity.
