Prep one video for four Chinese platforms with Codex

A developer used Codex to generate platform-specific upload details and coordinate four parallel assistants for Xiaohongshu, Douyin, Bilibili, and WeChat Channels.

What they did
They created a video-publishing Skill in Codex. The Skill uses its rules to make titles and tags, asks which destinations to target, and outputs one JSON checklist for each platform. Four sub-agents then open separate Ego Lite spaces and complete the upload screens at the same time, one site per agent. If a sign-in is missing, they stop, and any fix they discover gets written back into the Skill.
How it went
The video, title, and tag details usually land in the draft area, but the author still has to clean up some entries by hand. They said the process is not yet stable and did not give any timing or success metrics.
Tips
Keep checking each platform after the agent finishes, even when it reports success. Make sure the workflow pauses before any final posting action and asks for a human review first.

Try it yourself with Codex

I have a video saved at [file path] about [topic]. For [platform 1], [platform 2], [platform 3], and [platform 4], draft the title, description, and tags each site is likely to need, then open the upload page for each one and enter the video plus the text. Stop before any final publish or submit action. Show me each prefilled form and ask me to approve it before anything goes live. If you run into a missing login or another blocking problem, pause and report it first.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
