What the Codex App Really Controls (The Visibility Rule Explained)

Описание: OpenAI just shipped a standalone Codex desktop app for macOS. Not a ChatGPT tab. Not an IDE plugin. A standalone application sitting above your entire development environment.

But there's a visibility rule underneath it that nobody explains up front, and if you don't know it, half your work will seem invisible. I walked through every surface — cloud, desktop app, IDE side panel, CLI — and showed exactly what each one can and can't see.

This video breaks down the one mental model that makes thread visibility, worktrees, and the entire multi-surface Codex experience click: where you start a task is where that task lives. Downward visibility works. Upward visibility does not. Cloud floats above everything. The app sits below cloud but above your IDE. The CLI is a black box.

Beyond the visibility rule, I walk through the app's standout features: the Skills marketplace, MCP server configuration that lives above any single project, worktrees for parallel local work without file collisions, and Automations — essentially cron jobs for your AI coding agent.

If you use Codex across multiple surfaces, understanding this hierarchy saves you from chasing phantom threads.

If you're interested in AI-assisted development workflows, multi-agent orchestration, or managing parallel coding tasks, this breakdown covers how the Codex app fits into a real development workflow across cloud, desktop, IDE, and CLI. Whether you're just getting started with Codex or you've been using the CLI and side panel for months, the visibility rule and worktree walkthrough will clarify how all the pieces connect.
