Zero for Codex (CLI)

How to install Zero in the Codex CLI and keep it up to date.

Using the Codex desktop app? See the Codex app guide.

Install

Inside Codex CLI

Inside a Codex CLI session, run:

/plugin marketplace add officialzeroxyz/zero-plugins
/plugin install zero@zero-plugins
/reload-plugins

From the terminal

codex plugin marketplace add officialzeroxyz/zero-plugins
codex plugin add zero@zero-plugins

That's it — Zero sets itself up automatically. Ask Codex: "Help me set up and test Zero." It walks you through signing in.

Staying up to date

Nothing to do — updates are automatic:

• The Zero runner updates at the start of each session.
• The plugin itself checks for updates once a day, in the background, and they apply the next time you start Codex.

To turn off the daily plugin check, set ZERO_PLUGIN_AUTOUPDATE=0 in your environment.
