WHY IT NEEDS A POLICY

Why publish_with_video needs a policy

This tool creates and publishes new content (video posts) on Xiaohongshu, which is a reversible modification operation. While the content is posted publicly, the action itself can be undone by deleting the post. This fits the Write category rather than Execute because it is a content creation operation with predictable effects, not arbitrary code execution.

From the tool's definition Tool name 'publish_with_video' and description '发布小红书视频内容（仅支持本地单个视频文件）' (Publish Xiaohongshu video content - supports only local single video files) indicates content creation and posting to a social media platform.
