## Summary This PR lets programmatic AgentIdentity users provide one token through either stdin login or environment auth. `codex login --with-agent-identity` reads an Agent Identity JWT from stdin, validates that it has the required claims, and stores that token as the `agent_identity` value in `auth.json`. The file format is token-only; the decoded account and key fields are runtime state, not hand-authored auth.json fields. The Agent Identity JWT claim shape and decoder live in `codex-agent-identity`; `codex-login` only owns env/storage precedence and conversion into `CodexAuth::AgentIdentity`. When env auth is enabled, `CODEX_AGENT_IDENTITY` can provide the same JWT without writing auth state to disk. `CODEX_API_KEY` still wins if both env vars are set. Reference old stack: https://github.com/openai/codex/pull/17387/changes Reference JWT/env stack: https://github.com/openai/codex/pull/18176 ## Stack 1. https://github.com/openai/codex/pull/18757: full revert 2. https://github.com/openai/codex/pull/18871: isolated Agent Identity crate 3. https://github.com/openai/codex/pull/18785: explicit AgentIdentity auth mode and startup task allocation 4. https://github.com/openai/codex/pull/18811: migrate Codex backend auth callsites through AuthProvider 5. This PR: accept AgentIdentity JWTs through login/env ## Testing Tests: targeted login and Agent Identity crate tests, CLI checks, scoped formatter/linter cleanup, and CI. --------- Co-authored-by: Shijie Rao <shijie.rao@openai.com>

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.
