## Why The idea here is to erase the difference between initial and followup inputs to a turn. Followup inputs are already represented as TurnInput. Eventual goal is not to have explicit on task input at all and pull everything from input Q. ## What Changed - Changes `SessionTask::run` and the erased `AnySessionTask::run` path to accept `Vec<TurnInput>`. - Wraps user-submitted spawn input as `TurnInput::UserInput` at the session task start boundary. - Updates `run_turn` to record initial `TurnInput` using the same hook and recording path used for pending input. - Keeps review-specific conversion local to `ReviewTask`, where the sub-Codex one-shot API still expects `Vec<UserInput>`. - Moves the synthetic compact prompt into `CompactTask` and starts compact tasks with empty task input. ## Validation - `cargo check -p codex-core` - `just test -p codex-core -E 'test(task_finish_emits_turn_item_lifecycle_for_leftover_pending_user_input) | test(queued_response_items_for_next_turn_move_into_next_active_turn) | test(steered_input_reopens_mailbox_delivery_for_current_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.
