## Why `command/exec` is another app-server entry point that can run under caller-provided permissions. It needs to accept `PermissionProfile` directly so command execution is not left behind on `SandboxPolicy` while thread APIs move forward. Command-level profiles also need to preserve the semantics clients expect from profile-relative paths. `:cwd` and cwd-relative deny globs should be anchored to the resolved command cwd for a command-specific profile, while configured deny-read restrictions such as `**/*.env = none` still need to be enforced because they can come from config or requirements rather than the command override itself. ## What Changed This adds `permissionProfile` to `CommandExecParams`, rejects requests that combine it with `sandboxPolicy`, and converts accepted profiles into the runtime filesystem/network permissions used for command execution. When a command supplies a profile, the app-server resolves that profile against the command cwd instead of the thread/server cwd. It also preserves configured deny-read entries and `globScanMaxDepth` on the effective filesystem policy so one-off command overrides cannot drop those read protections. The PR also updates app-server docs/schema fixtures and adds command-exec coverage for accepted, rejected, cwd-scoped, and deny-read-preserving profile paths. ## Verification - `cargo test -p codex-app-server command_exec_permission_profile_cwd_uses_command_cwd` - `cargo test -p codex-app-server command_profile_preserves_configured_deny_read_restrictions` - `cargo test -p codex-app-server command_exec_accepts_permission_profile` - `cargo test -p codex-app-server command_exec_rejects_sandbox_policy_with_permission_profile` - `just fix -p codex-app-server` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.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.
