Baoyu Uses REA and Computer Use to Download 2,291 CapCut Templates

The author describes using Codex + REA to download a video playing in WeChat Channels with a simple prompt. One conversation round was insufficient; Codex configured a local proxy server, required several password entries to install certificates, and wrote a script to decrypt the downloaded video. The author presents this as a case study, notes that more mature download solutions likely exist, and suggests packaging the workflow as a Skill if it works reliably.

Baoyu describes using REA with Computer Use to investigate how CapCut renders dynamic subtitles, without knowing where their formats were stored. He had it operate CapCut, download Templates, and monitor network URLs and disk save locations. After downloading several dozen through clicks, Codex found clicking too slow and constructed URLs to download directly, ultimately downloading 2291 Templates.
