## Why https://github.com/openai/codex/pull/16287 introduced a change to `codex-rs/login/src/auth/auth_tests.rs` that uses a PowerShell helper to read the next token from `tokens.txt` and rewrite the remainder back to disk. On Windows, `Get-Content` can return a scalar when the file has only one remaining line, so `$lines[0]` reads the first character instead of the full token. That breaks the external bearer refresh test once the token list is nearly exhausted. https://github.com/openai/codex/pull/16288 introduced similar changes to `codex-rs/core/src/models_manager/manager_tests.rs` and `codex-rs/core/tests/suite/client.rs`. These went unnoticed because the failures showed up when the test was run via Cargo on Windows, but not in our Bazel harness. Figuring out that Cargo-vs-Bazel delta will happen in a follow-up PR. ## Verification On my Windows machine, I verified `cargo test` passes when run in `codex-rs/login` and `codex-rs/core`. Once this PR is merged, I will keep an eye on https://github.com/openai/codex/actions/workflows/rust-ci-full.yml to verify it goes green. ## What changed - Wrap `Get-Content -Path tokens.txt` in `@(...)` so the script always gets array semantics before counting, indexing, and rewriting the remaining lines.
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.
