## Why Remote-control HTTP requests applied the authentication headers and then appended `ChatGPT-Account-ID` again with `reqwest::RequestBuilder::header`. Since reqwest appends, the wire request could contain the same header twice. Intermediaries may coalesce duplicate values into `uuid,uuid`, which is not a valid account ID. ## What changed - Build remote-control request authentication headers in one place. - Apply provider headers first, then use `HeaderMap::insert` for the explicit account ID. This preserves the current account-ID precedence and all other authentication headers while ensuring exactly one account header is sent. - Preserve duplicate HTTP headers in the test harness and assert exactly one account header for enroll, refresh, list, and revoke requests. ## Validation Added focused coverage for: - Adding the explicit account header when the auth provider omits it. - Replacing multiple provider-supplied account values, including a differently cased header name. - Preserving authorization and routing headers while replacing only the account header. - Rejecting invalid account header values before sending a request. - Emitting exactly one account header for enroll, refresh, list, and revoke requests. - Maintaining header uniqueness across unauthorized recovery, retry, and error-response paths. - Emitting exactly one installation header for enroll and refresh requests. Checks run: - `just test -p codex-app-server-transport request_headers`: 3 passed - `just test -p codex-app-server-transport remote_control_http_mode`: 6 passed - `just test -p codex-app-server-transport clients_tests`: 6 passed - `just test -p codex-app-server-transport`: 123 passed - `cargo test -p codex-app-server-transport`: 123 passed - `just clippy -p codex-app-server-transport` - `just fmt-check` - `bazel test //codex-rs/app-server-transport:app-server-transport-unit-tests`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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
