Adds the app-server v2 goal API on top of the persisted goal state from PR 1. ## Why Clients need a stable app-server surface for reading and controlling materialized thread goals before the model tools and TUI can use them. Goal changes also need to be observable by app-server clients, including clients that resume an existing thread. ## What changed - Added v2 `thread/goal/get`, `thread/goal/set`, and `thread/goal/clear` RPCs for materialized threads. - Added `thread/goal/updated` and `thread/goal/cleared` notifications so clients can keep local goal state in sync. - Added resume/snapshot wiring so reconnecting clients see the current goal state for a thread. - Added app-server handlers that reconcile persisted rollout state before direct goal mutations. - Updated the app-server README plus generated JSON and TypeScript schema fixtures for the new API surface. ## Verification - Added app-server v2 coverage for goal get/set/clear behavior, notification emission, resume snapshots, and non-local thread-store interactions.
npm i -g @openai/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.
