OpenAI has embedded Codex directly into the ChatGPT mobile app, making full vibe coding and computer control available from a phone. The video, from Riley Brown, walks through the exact setup sequence: configuring chat-first settings, enabling voice mode, installing plugins and skills, and setting permissions. The Vercel-integrated vibe coding skill, which Brown calls YOLO Mode, is the functional core of the workflow.
The more consequential demonstration starts at 12:15, where Brown uses the ChatGPT app to control his desktop computer remotely. Out-of-the-box vibe coding has documented flaws, covered at 7:06, and the workarounds Brown uses are specific and repeatable, not theoretical. He centralizes his agent skills at chorus.com/skills, which signals this is an ongoing, maintained workflow rather than a one-off demo.
The reason to watch the full video is the computer control segment and the honest acknowledgment of where Codex Mobile breaks without the right skill stack. The setup details between minutes 2 and 7 determine whether any of the rest works. Skip those and the YOLO Mode demonstration will not replicate cleanly.
