Your Idea

Image content requires a MIME Type field to specify the encoding of the image data.

An optional MIME type on text content would be useful, specifically for tool responses that involved structured data. Currently all text is assumed to be text/plain, but supporting alternate mime types eg. application/json text/csv would aid in clients using tool replies and allow rich text display of tool responses on host applications.
