Practical overview

When it fits

Use it when a Codex coding session would benefit from ChatGPT-based planning or review and the documented local bridge setup fits the development environment.

Who it is for

  • Developers using Codex for repository changes
  • Users with a ChatGPT web subscription who want ChatGPT to support planning and code review
  • Developers interested in a local MCP-based bridge between a coding agent and ChatGPT

Documented uses

  • Generate planning input for Codex coding sessions
  • Obtain review input during repository work
  • Let Codex execute changes while ChatGPT supplies high-level reasoning
  • Configure a ChatGPT connector for a Codex workspace
Before you choose

Requirements & limits

The repository is public, open source and licensed under MIT. The documented setup uses ChatGPT sign-in and may involve Cloudflare authentication for a stable hostname.

  • It uses the ChatGPT web interface rather than a demonstrated provider-agnostic model layer.
  • The bridge is described as read-only and OAuth-protected.
  • Codex remains responsible for executing repository changes.
  • Node.js 20 or later, Git, cloudflared and Corepack pnpm are part of the documented setup.
  • A temporary Cloudflare address is used by default; a stable hostname requires an existing Cloudflare-managed domain.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install and configure the Codex Skill

Build the repository, install its Codex Skill, and configure the ChatGPT connector.

Before you start

  • Git
  • Node.js 20 or later
  • cloudflared
  • Corepack pnpm
  • A Codex home directory

Steps

  1. Clone or update the repository checkout.

  2. Run corepack pnpm install, then corepack pnpm build in the repository directory.

  3. Copy skill/SKILL.md into /skills/codex-with-chatgpt/SKILL.md and update the checkout path in that file.

  4. Run c2c setup and configure the ChatGPT connector in the built-in browser using the pairing code.

Expected outcome

The Codex Skill is installed and the ChatGPT connector is configured for the workspace.

Guide limitations

  • The documented process may require ChatGPT login, CAPTCHA or two-factor authentication.
  • A new workspace requires a ChatGPT Project with project-only memory.
  • A stable hostname additionally requires a Cloudflare account and a domain already on Cloudflare.
