## Why The `notify` hook payload did not identify which Codex client started the turn. That meant downstream notification hooks could not distinguish between completions coming from the TUI and completions coming from app-server clients such as VS Code or Xcode. Now that the Codex App provides its own desktop notifications, it would be nice to be able to filter those out. This change adds that context without changing the existing payload shape for callers that do not know the client name, and keeps the new end-to-end test cross-platform. ## What changed - added an optional top-level `client` field to the legacy `notify` JSON payload - threaded that value through `core` and `hooks`; the internal session and turn state now carries it as `app_server_client_name` - set the field to `codex-tui` for TUI turns - captured `initialize.clientInfo.name` in the app server and applied it to subsequent turns before dispatching hooks - replaced the notify integration test hook with a `python3` script so the test does not rely on Unix shell permissions or `bash` - documented the new field in `docs/config.md` ## Testing - `cargo test -p codex-hooks` - `cargo test -p codex-tui` - `cargo test -p codex-app-server suite::v2::initialize::turn_start_notify_payload_includes_initialize_client_name -- --exact --nocapture` - `cargo test -p codex-core` (`src/lib.rs` passed; `core/tests/all.rs` still has unrelated existing failures in this environment) ## Docs The public config reference on `developers.openai.com/codex` should mention that the legacy `notify` payload may include a top-level `client` field. The TUI reports `codex-tui`, and the app server reports `initialize.clientInfo.name` when it is available.
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.
