## Why Extensions can already contribute prompt, tool, turn-item, and thread-lifecycle behavior, but there was no explicit host-owned hook for per-turn setup and cleanup. That makes extension-private turn state awkward: an extension either has to stash it outside the turn lifecycle or depend on core runtime objects. This adds a small turn lifecycle boundary. Extensions receive stable identifiers plus the existing session, thread, and turn `ExtensionData` stores, while core keeps owning task scheduling, cancellation, and turn teardown. ## What Changed - Added `TurnLifecycleContributor` with `on_turn_start`, `on_turn_stop`, and `on_turn_abort` callbacks in `codex-rs/ext/extension-api`. - Added typed `TurnStartInput`, `TurnStopInput`, and `TurnAbortInput` payloads that expose `thread_id`, `turn_id`, `session_store`, `thread_store`, and `turn_store`. - Registered and re-exported turn lifecycle contributors through `ExtensionRegistry` and `ExtensionRegistryBuilder`. - Wired `Session` to emit turn start, stop, and abort callbacks from the existing turn/task lifecycle paths. - Carried the turn-scoped `ExtensionData` through `RunningTask` and `RemovedTask` so stop/abort callbacks receive the same turn store created at turn start. ## Verification - Not run locally.
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.
