## Why App-server clients sometimes need argv-based local process execution while sandbox policy is controlled outside Codex. Those environments can reject sandbox-disabling paths before a command ever starts, even when the caller intentionally wants unsandboxed execution. This PR adds a distinct `process/*` API for that use case instead of extending `command/exec` with another sandbox-disabling shape. Keeping the new surface separate also makes the future removal of `command/exec` simpler: clients that need explicit process lifecycle control can move to the newer handle-based API without depending on `command/exec` business logic. ## What changed - Added v2 process lifecycle methods: `process/spawn`, `process/writeStdin`, `process/resizePty`, and `process/kill`. - Added process notifications: `process/outputDelta` for streamed stdout/stderr chunks and `process/exited` for final exit status and buffered output. - Made `process/spawn` intentionally unsandboxed and omitted sandbox-selection fields such as `sandboxPolicy` and `permissionProfile`. - Added client-supplied, connection-scoped `processHandle` values for follow-up control requests and notification routing. - Supported cwd, environment overrides, PTY mode and size, stdin streaming, stdout/stderr streaming, per-stream output caps, and timeout controls. - Killed active process sessions when the originating app-server connection closes. - Wired the implementation through the modular `request_processors/` app-server layout, with process-handle request serialization for follow-up control calls. - Updated generated JSON/TypeScript schema fixtures and documented the new API in `codex-rs/app-server/README.md`. - Added v2 app-server integration coverage in `codex-rs/app-server/tests/suite/v2/process_exec.rs` for spawn acknowledgement before exit, buffered output caps, and process termination. ## Verification - `cargo test -p codex-app-server-protocol` - `cargo test -p codex-app-server` --------- Co-authored-by: Owen Lin <owen@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.
