Why publish_photo needs a policy

Publishing content to Instagram is a reversible write operation—posts can be edited or deleted after creation. It modifies the account's public feed state. Severity is medium because misuse could result in unwanted public content, brand damage, or spam, but the action itself is not irreversible (unlike delete_media) and carries no financial obligation or code execution risk.

From the tool's definition Tool name 'publish_photo' and description explicitly states 'Publish a photo to your Instagram feed' with caption support. This creates new content on a public platform.
