## Why A process host should be discarded and rebuilt after critical actor or V8 failure, while the existing in-process production path must keep its current cell-error semantics. This change establishes that failure boundary without adding the host process or remote client. ## What changed - add optional task-failure supervision to the transport-neutral code-mode session runtime - report Tokio cell-actor failures and V8 runtime-thread panics to a host-provided fail-stop handler - preserve the existing handler-less in-process behavior - make host-owned cell ID allocation fail before numeric wraparound ## Follow-up The V8 panic signal surfaced here should also be consumed by the `InProcessCodeModeSession` manager in a future change so it can fail the affected cell. This PR intentionally leaves the handler-less in-process behavior unchanged while putting the required panic tracking in place. ## Stack This is **2 of 4** in the process-owned code-mode session stack. - #30108 is merged into `main` - The next PR targets this branch ## Validation - `just test -p codex-code-mode` — 53 passed - `just argument-comment-lint -p codex-code-mode` - `just fix -p codex-code-mode`
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.
