## Summary - add an exec-server `envPolicy` field; when present, the server starts from its own process env and applies the shell environment policy there - keep `env` as the exact environment for local/embedded starts, but make it an overlay for remote unified-exec starts - move the shell-environment-policy builder into `codex-config` so Core and exec-server share the inherit/filter/set/include behavior - overlay only runtime/sandbox/network deltas from Core onto the exec-server-derived env ## Why Remote unified exec was materializing the shell env inside Core and forwarding the whole map to exec-server, so remote processes could inherit the orchestrator machine's `HOME`, `PATH`, etc. This keeps the base env on the executor while preserving Core-owned runtime additions like `CODEX_THREAD_ID`, unified-exec defaults, network proxy env, and sandbox marker env. ## Validation - `just fmt` - `git diff --check` - `cargo test -p codex-exec-server --lib` - `cargo test -p codex-core --lib unified_exec::process_manager::tests` - `cargo test -p codex-core --lib exec_env::tests` - `cargo test -p codex-core --lib exec_env_tests` (compile-only; filter matched 0 tests) - `cargo test -p codex-config --lib shell_environment` (compile-only; filter matched 0 tests) - `just bazel-lock-update` ## Known local validation issue - `just bazel-lock-check` is not runnable in this checkout: it invokes `./scripts/check-module-bazel-lock.sh`, which is missing. --------- Co-authored-by: Codex <noreply@openai.com> Co-authored-by: pakrym-oai <pakrym@openai.com>
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.
