How to use

The latest version of Zed can already use this adapter out of the box.

To use Codex, open the Agent Panel and click "New Codex Thread" from the + button menu in the top-right.

Read the docs on External Agent support.

Or try it with any of the other ACP compatible clients!

Install the adapter from the latest release for your architecture and OS: https://github.com/zed-industries/codex-acp/releases

You can then use codex-acp as a regular ACP agent:

OPENAI_API_KEY=sk-... codex-acp

Or via npm:

npx @zed-industries/codex-acp
