Guizang uses Grok bot to read a GitHub project and produce a promo video

Guizang (歸藏, @op7418) says he asked Grok, via its @bot account, to read one of his GitHub projects and make a promotional video for it, and he shared the resulting video.

The only report so far is his own X post, which does not name the project, describe what Grok did, or say how the video was made or how well it turned out. The claim that Grok produced the video therefore rests on his statement alone.
