## Summary This adds `experimental_network.danger_full_access_denylist_only` for orgs that want yolo / danger-full-access sessions to keep full network access while still enforcing centrally managed deny rules. When the flag is true and the session sandbox is `danger-full-access`, the network proxy starts with: - domain allowlist set to `*` - managed domain `deny` entries enforced - upstream proxy use allowed - all Unix sockets allowed - local/private binding allowed Caveat: the denylist is best effort only. In yolo / danger-full-access mode, Codex or the model can use an allowed socket or other local/private network path to bypass the proxy denylist, so this should not be treated as a hard security boundary. The flag is intentionally scoped to `SandboxPolicy::DangerFullAccess`. Read-only and workspace-write modes keep the existing managed/user allowlist, denylist, Unix socket, and local-binding behavior. This does not enable the non-loopback proxy listener setting; that still requires its own explicit config. This also threads the new field through config requirements parsing, app-server protocol/schema output, config API mapping, and the TUI debug config output. ## How to use Add the flag under `[experimental_network]` in the network policy config that is delivered to Codex. The setting is not under `[permissions]`. ```toml [experimental_network] enabled = true danger_full_access_denylist_only = true [experimental_network.domains] "blocked.example.com" = "deny" "*.blocked.example.com" = "deny" ``` With that configuration, yolo / danger-full-access sessions get broad network access except for the managed denied domains above. The denylist remains a best-effort proxy policy because the session may still use allowed sockets to bypass it. Other sandbox modes do not get the wildcard domain allowlist or the socket/local-binding relaxations from this flag. ## Verification - `cargo test -p codex-config network_requirements` - `cargo test -p codex-core network_proxy_spec` - `cargo test -p codex-app-server map_requirements_toml_to_api` - `cargo test -p codex-tui debug_config_output` - `cargo test -p codex-app-server-protocol` - `just write-app-server-schema` - `just fmt` - `just fix -p codex-config -p codex-core -p codex-app-server-protocol -p codex-app-server -p codex-tui` - `just fix -p codex-core -p codex-config` - `git diff --check` - `cargo clean`
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.
