Codex

Codex is OpenAI’s open-source coding agent that runs in your terminal. It can write and edit code, execute commands, and navigate your codebase through natural language. For full documentation, see the Codex GitHub repository.

Warp auto-detects Codex when you run it, giving you access to rich input controls, code review, and other integrated features. For a product overview, see Codex in Warp.

For installation, authentication, project configuration, and productivity tips, see the How to set up Codex CLI guide.

Setting up notifications

Codex supports native notifications that Warp surfaces as in-app and desktop alerts — such as when Codex completes a task, encounters an error, or needs your input.

First, update Codex to the latest version — support for this setting was recently added. See the Codex upgrade instructions.

Then add the following to ~/.codex/config.toml:

[tui]
notification_condition = "always"

Then restart Codex. If this config isn’t set, Warp displays a setup chip in the terminal with instructions you can follow directly.

Supported Warp features

Codex supports the full set of Warp’s agent integration features:

• Agent notifications - Receive in-app and desktop alerts when Codex needs your attention. Requires a one-time config change (see Setting up notifications).
• Rich input editor - Press Ctrl-G to open an expanded input editor for composing longer prompts.
• Code review - Send inline review comments directly to the agent from Warp’s code review panel.
• Attach code as context - Select code and send it to the agent as context.
• Vertical tabs with agent metadata - Monitor Codex sessions with status indicators in Warp’s tab bar.
• Tab Configs - Save and restore Codex session configurations.
• Remote Control - Share your Codex session with teammates via session sharing.
