## Why The app-server and exec-server expose separate JSON-RPC APIs, but exec-server currently sources its serialized protocol and envelope types through app-server-oriented code. Giving each API an explicit owner makes the crate boundary legible without introducing shared generic envelopes. ## What changed - Added `codex-exec-server-protocol` to own exec DTOs, process IDs, and JSON-RPC envelopes. - Updated exec-server clients, transports, handlers, and tests to use the new crate. - Exposed app-server's existing JSON-RPC types through a public `rpc` module while retaining root re-exports. - Preserved existing wire shapes, including exec `PathUri` behavior. ## Stack This is PR 1 of 6. Next: [PR #29721](https://github.com/openai/codex/pull/29721), which moves auth mode below the app wire boundary. ## Validation - Exec-server protocol and server coverage passed in the focused protocol test runs. - App-server protocol schema fixtures passed.
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
