## Why On Windows, Codex runs shell commands through a top-level `powershell.exe -NoProfile -Command ...` wrapper. `execpolicy` was matching that wrapper instead of the inner command, so prefix rules like `["git", "push"]` did not fire for PowerShell-wrapped commands even though the same normalization already happens for `bash -lc` on Unix. This change makes the Windows shell wrapper transparent to rule matching while preserving the existing Windows unmatched-command safelist and dangerous-command heuristics. ## What changed - add `parse_powershell_command_plain_commands()` in `shell-command/src/powershell.rs` to unwrap the top-level PowerShell `-Command` body with `extract_powershell_command()` and parse it with the existing PowerShell AST parser - update `core/src/exec_policy.rs` so `commands_for_exec_policy()` treats top-level PowerShell wrappers like `bash -lc` and evaluates rules against the parsed inner commands - carry a small `ExecPolicyCommandOrigin` through unmatched-command evaluation and expose `is_safe_powershell_words()` / `is_dangerous_powershell_words()` so Windows safelist and dangerous-command checks still work after unwrap - add Windows-focused tests for wrapped PowerShell prompt/allow matches, wrapper parsing, and unmatched safe/dangerous inner commands, and re-enable the end-to-end `execpolicy_blocks_shell_invocation` test on Windows ## Testing - `cargo test -p codex-shell-command`

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.
