Abhinav 78baa20780 deprecate legacy notify (#20524)
# Why

`notify` is the remaining compatibility surface from the legacy hook
implementation. The newer lifecycle hook engine now owns the active hook
system, so we should start steering users away from adding new `notify`
configs before removing the old path entirely. This also adds a
lightweight watchpoint for the deprecation so we can see how much legacy
usage remains before the clean drop.

# What

- emit a startup deprecation notice when a non-empty `notify` command is
configured
- emit `codex.notify.configured` when a session starts with legacy
`notify` configured
- emit `codex.notify.run` when the legacy notify path fires after a
completed turn
- mark `notify` as deprecated in the config schema and repo docs
- remove the orphaned `codex-rs/hooks/src/user_notification.rs` file
that is no longer compiled
- add regression coverage for the new deprecation notice

# Next steps

A follow-up PR can remove the legacy notify path entirely once we are
ready for the clean drop. Before then, we can watch
`codex.notify.configured` and `codex.notify.run` to understand the
deprecation impact and remaining active usage. The cleanup PR should
then delete the `notify` config field, the `legacy_notify`
implementation, the old compatibility dispatch types and callsites that
only exist for the legacy path, and the remaining compatibility
docs/tests.

# Testing

- `cargo test -p codex-hooks`
- `cargo test -p codex-config`
- `cargo test -p codex-core emits_deprecation_notice_for_notify`

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.
