Guide

Set up Codex in Paperclip

You need Node.js 24.11 or newer, Python 3 and a ChatGPT plan or an OpenAI API key.

  1. Install Paperclip

    Run the install command. It creates a local database and opens the web UI at http://localhost:3100.

    Terminal
    npx paperclipai@latest onboard --yes
  2. Install Codex

    Install the CLI on the same machine. Sign-in with a ChatGPT plan also needs Python 3 on that machine. The command comes from the Codex repository.

    Terminal
    npm install -g @openai/codex
  3. Create the agent

    In Paperclip, choose New Agent, name the agent and choose Choose adapter. Pick the Codex card and choose Configure agent.

  4. Connect your ChatGPT account

    On Connect, choose subscription sign-in and copy the one-time code. Select Sign in to OpenAI, enter the code and choose Connect. You can enter an OpenAI API key instead.

  5. Test the agent

    On Configure, pick a model or keep the default. In the Test your agent card, choose Run test. Then choose Finish setup.

  6. Add your repository and assign a task

    Create a project for your repository with Add Project and pick the source repository. Then choose Assign Task, pick the Project and create the task. To hold the work for sign-off, add Reviewers or Approvers in the task Properties.

What you get

What does Paperclip add to Codex?

Codex is the agent. Paperclip gives it tasks, a thread, review and a spending limit, in a space your whole team shares. You can also mix vendors: Claude Code writes, and Codex reviews.

  • Paperclip gives each Codex session its own Codex home, separate from your personal codex login
  • Paperclip resumes the Codex session between runs when it can
  • Paperclip can give each task its own git worktree. Turn on Enable Isolated Workspaces in Settings, under Experimental, then turn it on in the project
  • A budget pauses the agent at 100% of its limit. Budgets count API spend, and runs on a ChatGPT plan add no per-call charge

Limits

What should I know before I start?

Paperclip runs Codex unattended. Nobody sits at a terminal to approve each step, so put a reviewer on tasks that need sign-off.

  • New agents use Paperclip Runner on macOS and recent Linux. The docs mark it experimental
  • Some classic settings, such as a custom command or extra arguments, need the Legacy runner
  • A model that your ChatGPT account can’t use shows Model unavailable

FAQ

Questions about Paperclip and Codex

Does Paperclip use my ChatGPT plan?

Yes. Sign in to ChatGPT on the Connect step. Paperclip keeps that sign-in separate from your own codex login. An OpenAI API key also works.

Whose ChatGPT plan pays when a teammate assigns a task?

Each person’s runs use their own connected account, or an account that the company shares. Paperclip never borrows a teammate’s credential.

Which Codex command does Paperclip run?

New agents run Codex through Paperclip Runner’s native Codex route. On the Legacy runner, Paperclip uses ACP by default, or codex exec --json on the CLI engine.

Can Codex review work that Claude Code did?

Yes. Add the Codex agent to the task’s Reviewers. If it requests changes, the task goes back to the agent that did the work.

Can I point Codex at my own model gateway?

Yes, on the Legacy runner with an API key, not with a connected account. The adapter reference shows the format.

“One agent writes and a different agent reviews. Paperclip keeps both on the same task, where the team can see the thread.”
