## Summary This changes `js_repl` so saved references to `codex.tool(...)` and `codex.emitImage(...)` keep working across cells. Previously, those helpers were recreated per exec and captured that exec's `message.id`. If a persisted object or saved closure reused an old helper in a later cell, the nested tool/image call could fail with `js_repl exec context not found`. This patch: - keeps stable `codex.tool` and `codex.emitImage` helper identities in the kernel - resolves the current exec dynamically at call time using `AsyncLocalStorage` - adds regression coverage for persisted helper references across cells - updates the js_repl docs and project-doc instructions to describe the new behavior and its limits ## Why We already support persistent top-level bindings across `js_repl` cells, so persisted objects should be able to reuse `codex` helpers in later active cells. The bug was that helper identity was exec-scoped, not kernel-scoped. Using `AsyncLocalStorage` fixes the cross-cell reuse case without falling back to a single global active exec that could accidentally attribute stale background callbacks to the wrong cell.
npm i -g @openai/codex
or brew install --cask 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.
