继续测试 OpenAI Operator，华而不实呀！让它用 v0 dev 给我做个页面，做完了给我测试好。第一次不知道去YouTube找个真的URL帮我测试，非要编造一个，第二次出 Bug 了，点了fix按钮，但是不知道发送消息，得我手动接管，后来不知道怎么就卡死了。 Prompt：Please use v0[.]dev to build a page which can download a youtube video's thumbnail via youtube url, seo friendly. please find a sample video from youtube[.]com to verify it after you finish developing, no need to confirm anything with me, just build and test, share the project url with me when it works.
