## Why This PR is stacked on #24918, which moves goal steering onto source-labeled internal model context fragments. Active-turn goal steering should use the same running-turn injection path as other runtime steering, so those fragments enter the pending input queue as `ResponseItem`s through the existing [`Session::inject_if_running`](https://github.com/openai/codex/blob/8d6f6cdf69b055c27682e7cdea9caf72a3e2ee7f/codex-rs/core/src/session/inject.rs#L12-L27) behavior instead of through a goal-specific conversion wrapper. ## What Changed - Exposes a narrow `CodexThread::inject_if_running` bridge for callers that only hold a thread handle. - Changes `ext/goal` active-turn steering to pass `ResponseItem`s directly. - Builds goal steering prompts as contextual internal model context `ResponseItem`s before injecting them into the running turn. ## Testing Not run locally; PR metadata update only.
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.
