Codex comes in six flavors; this guide explains when to pick each

What it does

CodexGuide is a Chinese-language, task-oriented knowledge base for OpenAI Codex. It walks beginners through their first desktop-app task, helps developers wire the CLI into real repositories, and gives team leads templates for AGENTS.md, sandbox rules, and shared playbooks. The whole thing is published as a VuePress site at codexguide.ai, with content explicitly dated so you know when to re-check OpenAI’s official docs.

The interesting bit

Most Codex content stops at “look, it wrote a function.” This project treats Codex as a multi-entry workflow system—desktop, CLI, Cloud, IDE, mobile—and focuses on the boring but valuable part: how to verify output, manage credentials, and turn one successful prompt into a reusable team standard.

Key highlights

• Covers six distinct entry points (desktop app, CLI, Cloud, IDE, ChatGPT mobile, browser) with specific trade-offs for each.
• Heavy emphasis on safety: sandbox approvals, credential handling, and explicit “when not to do this” warnings.
• Includes non-dev workflows—PPT generation, Obsidian knowledge bases, clinical literature reviews, Figma/Notion automation.
• Provides AGENTS.md templates and team playbooks for turning individual hacks into repeatable processes.
• Dates its content against official OpenAI sources so readers know when advice may have drifted.

Caveats

• Primarily written in Chinese; English speakers get a translated README but the deep content is 中文.
• Explicitly not an official OpenAI project, so feature and pricing details can stale-date quickly.
• The repo is essentially a VuePress documentation site, not a tool you install or import.

Verdict

Worth bookmarking if you are onboarding a team to Codex or trying to move from “impressive demo” to “daily workflow.” Skip it if you are looking for a Codex alternative or a drop-in CLI plugin.
