## Summary - make `CODEX_EXEC_SERVER_URL=none` map to an explicit disabled environment mode instead of inferring from a missing URL - expose environment capabilities (`exec_enabled`, `filesystem_enabled`) so tool building can gate behavior explicitly and future multi-environment work has a clearer seam - suppress env-backed tools when the relevant capability is unavailable, including exec tools, `js_repl`, `apply_patch`, `list_dir`, and `view_image` - keep handler/runtime backstops so disabled environments still reject execution if a tool path somehow bypasses registration ## Testing - `just fmt` - `cargo test -p codex-exec-server` - `cargo test -p codex-tools disabled_environment_omits_environment_backed_tools` - `cargo test -p codex-tools environment_capabilities_gate_exec_and_filesystem_tools_independently` - remote devbox Bazel build via `codex-applied-devbox`: `//codex-rs/cli:cli`
npm i -g @openai/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.
