Correct the `shell` tool description for sandboxed runs and add targeted tests. - Fix the WorkspaceWrite description to clearly state that writes outside the writable roots require escalated permissions; reads are not restricted. The previous wording/formatting could be read as restricting reads outside the workspace. - Render the writable roots list on its own lines under a newline after "writable roots:" for clarity. - Show the "Commands that require network access" note only in WorkspaceWrite when network is disabled. - Add focused tests that call `create_shell_tool_for_sandbox` directly and assert the exact description text for WorkspaceWrite, ReadOnly, and DangerFullAccess. - Update AGENTS.md to note that `just fmt` can be run automatically without asking.
OpenAI Codex CLI
npm i -g @openai/codex
or brew install codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you are looking for the cloud-based agent from OpenAI, Codex Web, see chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager. If you use npm:
npm install -g @openai/codex
Alternatively, if you use Homebrew:
brew install codex
Then simply run codex to get started:
codex
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.
