## Why This is the first PR in a stack for the Windows fs-helper sandbox fix. Before changing fs-helper behavior, this pulls the reusable Windows sandbox session launch pieces out of the debug CLI path so later PRs can call the same backend selection and stdio forwarding logic. Keeping this as a pure refactor makes the later security fix easier to review: `codex sandbox windows` should continue to launch the same elevated or restricted-token backend, just through shared APIs in `windows-sandbox-rs` instead of code local to `cli/src/debug_sandbox.rs`. ## What Changed - Added `WindowsSandboxSessionRequest` and `spawn_windows_sandbox_session_for_level()` in `windows-sandbox-rs` to share the elevated-vs-legacy session launch decision. - Moved the Windows sandbox stdio forwarding helpers from `cli/src/debug_sandbox.rs` into `windows-sandbox-rs/src/stdio_bridge.rs`. - Updated `codex sandbox windows` to call the shared session launcher and stdio bridge. - Added unit coverage for the moved stdio forwarding helpers. ## Verification - `just bazel-lock-update` - `just bazel-lock-check` - `just test -p codex-windows-sandbox stdio_bridge::tests` - `just fix -p codex-windows-sandbox -p codex-sandboxing -p codex-exec-server -p codex-arg0 -p codex-core -p codex-file-system` - The new `stdio_bridge` tests also passed as part of `just test -p codex-windows-sandbox` on the stack tip. That full local run still fails in pre-existing legacy session integration tests with `CreateRestrictedToken failed: 87` on this workstation.
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.
