## Why `codex sandbox` now always runs the host sandbox backend, so it should accept the same profile selection mechanism as the rest of the runtime CLI surface. Without `--profile`, sandbox debugging can exercise only the default config stack unless users manually translate profile config into ad hoc `-c` overrides. Supporting `--profile` lets sandbox invocations load `$CODEX_HOME/<name>.config.toml`, including permission profile configuration, before resolving the sandbox policy for the command being run. ## What Changed - Added `--profile NAME` / `-p NAME` to the host-specific `codex sandbox` argument structs as `config_profile`. - Allowed root-level `codex --profile NAME sandbox ...` and made a sandbox-local `codex sandbox --profile NAME ...` override the root selection. - Threaded `LoaderOverrides` through sandbox config loading so selected config profile files participate in permission resolution before the legacy read-only fallback. - Documented the new sandbox flag in `codex-rs/README.md`. ## Verification - Added parser coverage for `codex sandbox --profile`. - Added sandbox config-loader coverage that verifies selected config profile loader overrides select the profile config rather than falling back to read-only. - Ran `cargo test -p codex-cli`.
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.
