## Why `PermissionProfile` is the canonical runtime permission model in the Rust workspace, but the Linux sandbox helper still accepted a legacy `SandboxPolicy` plus separate filesystem and network policy flags. That translation layer made the helper interface harder to reason about and left `linux-sandbox`-specific callers and tests coupled to the legacy policy representation. This change moves the helper onto `PermissionProfile` directly so the Linux sandbox plumbing matches the rest of the permission stack. ## What changed - changed `codex-linux-sandbox` to accept `--permission-profile` and derive the runtime filesystem and network policies internally - updated the in-process seccomp and legacy Landlock path in `codex-rs/linux-sandbox` to operate on `PermissionProfile` - updated Linux sandbox argv construction in `codex-rs/sandboxing`, `codex-rs/core`, and the CLI debug sandbox path to pass the canonical profile instead of serializing compatibility policy projections - simplified the Linux sandbox tests to build the exact permission profile under test, including the managed-proxy path and direct-runtime-enforcement carveout coverage - removed helper-local `SandboxPolicy` usage from `bwrap` tests where `FileSystemSandboxPolicy` is already the value being exercised ## Testing - `cargo test -p codex-sandboxing` - `cargo test -p codex-linux-sandbox` (on this macOS host, the crate compiled cleanly and its Linux-only tests were cfg-gated) - `cargo test -p codex-core --no-run` - `cargo test -p codex-cli --no-run`
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.
