## Why The Docker remote-env coverage was failing before it reached the behavior those tests are meant to exercise. The remote-aware test fixture only registered the remote environment, so tests that intentionally select both `local` and `remote` could not start a turn. After that was fixed, two tests exposed stale fixtures: the approval test was auto-approving under workspace-write, and the remote `view_image` test was writing invalid PNG bytes. ## What Changed - Added `EnvironmentManager::create_for_tests_with_local(...)` so tests can keep the provider default while also selecting `local` explicitly. - Updated `build_remote_aware()` to use that test-only manager when a remote exec-server URL is present. - Changed the remote apply-patch approval helper to use `SandboxPolicy::new_read_only_policy()` so the test actually exercises approval caching per environment. - Replaced the hardcoded remote `view_image` PNG blob with the existing `png_bytes(...)` helper so the test uses a valid image fixture. ## Validation Ran these isolated Docker remote-env tests on the devbox with `$remote-tests` setup: - `suite::remote_env::apply_patch_freeform_routes_to_selected_remote_environment` - `suite::remote_env::apply_patch_approvals_are_remembered_per_environment` - `suite::remote_env::apply_patch_intercepted_exec_command_routes_to_selected_remote_environment` - `suite::remote_env::exec_command_routes_to_selected_remote_environment` - `suite::view_image::view_image_routes_to_selected_remote_environment` All five pass.
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.
