OpenAI Codex App First Look, Automations + MCP + Skills is Crazy

OpenAI just launched the Codex app, and it’s not just “chat with code”.

In this video, I do a full hands-on walkthrough of Codex, including the parts that actually matter for builders:

Starter prompts and how to structure prompts properly

Command mode, where Codex can run actions and commands

Plan mode, where Codex proposes a plan first, then you approve it

MCP server support, so you can connect multiple tool servers

Automations, scheduled tasks like “scan recent commits for bugs” and more

A real demo build: cloning an AI presentation generator (Gamma-like) inside Codex

You’ll see how the workflow feels from start to finish, how the plan approval works, what options you can choose (slides, palette, template library), and how Codex verifies and fixes output inside the IDE.
