WHY IT NEEDS A POLICY

Why gdoc_insert_inline_image needs a policy

This tool modifies document content by adding an image to the document. While the insertion can be undone (unlike Destructive operations), it permanently changes the document state and could be misused to inject unwanted content, add spam images, or deface documents if an AI agent acts without proper authorization. This fits the Write category (creates/modifies data reversibly).

From the tool's definition Tool name 'gdoc_insert_inline_image' and description 'Insert an image from a URL at a specific position in the document' indicate content modification.
