## Summary This PR adds `CodexAuth::AgentIdentity` as an explicit auth mode. An AgentIdentity auth record is a standalone `auth.json` mode. When `AuthManager::auth().await` loads that mode, it registers one process-scoped task and stores it in runtime-only state on the auth value. Header creation stays synchronous after that because the task is initialized before callers receive the auth object. This PR also removes the old feature flag path. AgentIdentity is selected by explicit auth mode, not by a hidden flag or lazy mutation of ChatGPT auth records. Reference old stack: https://github.com/openai/codex/pull/17387/changes ## Design Decisions - AgentIdentity is a real auth enum variant because it can be the only credential in `auth.json`. - The process task is ephemeral runtime state. It is not serialized and is not stored in rollout/session data. - Account/user metadata needed by existing Codex backend checks lives on the AgentIdentity record for now. - `is_chatgpt_auth()` remains token-specific. - `uses_codex_backend()` is the broader predicate for ChatGPT-token auth and AgentIdentity auth. ## Stack 1. https://github.com/openai/codex/pull/18757: full revert 2. https://github.com/openai/codex/pull/18871: isolated Agent Identity crate 3. This PR: explicit AgentIdentity auth mode and startup task allocation 4. https://github.com/openai/codex/pull/18811: migrate Codex backend auth callsites through AuthProvider 5. https://github.com/openai/codex/pull/18904: accept AgentIdentity JWTs and load `CODEX_AGENT_IDENTITY` ## Testing Tests: targeted Rust checks, cargo-shear, Bazel lock check, and CI.

npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
