## Stack 1. [#26547](https://github.com/openai/codex/pull/26547) - [1 of 2] Align goal extension with core behavior 2. [#26548](https://github.com/openai/codex/pull/26548) - [2 of 2] Move goal runtime to extension ## Why The goal runtime is moving out of `codex-core` and into `codex-goal-extension`. This first PR brings the extension back in line with the current core behavior before the follow-up PR switches app-server sessions over to the extension, so that review can focus on ownership and wiring rather than hidden behavior drift. ## What Changed - Updates the extension `create_goal` and `update_goal` tool schemas/descriptions to match the current core wording for explicit token budgets, blocked-goal audits, resumed blocked goals, and system-owned budget/usage-limit transitions. - Marks `codex-goal-extension` as the live `/goal` extension crate rather than an unwired sketch. - Looks up the live thread before reading goal state for idle continuation, so continuation setup exits early when no live thread can accept the automatic turn.
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.
