## Why Plugins can bundle lifecycle hooks, but Codex previously only discovered hooks from user, project, and managed config layers. This adds the plugin discovery and runtime plumbing needed for plugin-bundled hooks while keeping execution behind the `plugin_hooks` feature flag. ## What - Discovers plugin hook sources from each plugin's default `hooks/hooks.json`. - Supports `plugin.json` manifest `hooks` entries as either relative paths or inline hook objects. - Plumbs discovered plugin hook sources through plugin loading into the hook runtime when `plugin_hooks` is enabled. - Marks plugin-originated hook runs as `HookSource::Plugin`. - Injects `PLUGIN_ROOT` and `CLAUDE_PLUGIN_ROOT` into plugin hook command environments. - Updates generated schemas and hook source metadata for the plugin hook source. ## Stack 1. This PR - openai/codex#19705 2. openai/codex#19778 3. openai/codex#19840 4. openai/codex#19882 ## Reviewer Notes - Core logic is in `codex-rs/core-plugins/src/loader.rs` and `codex-rs/hooks/src/engine/discovery.rs` - Moved existing / adding new tests to `codex-rs/core-plugins/src/loader_tests.rs` hence the large diff there - Otherwise mostly plumbing and minor schema updates ### Core Changes The `codex-rs/core` changes are limited to wiring plugin hook support into existing core flows: - `core/src/session/session.rs` conditionally pulls effective plugin hook sources and plugin hook load warnings from `PluginsManager` when `plugin_hooks` is enabled, then passes them into `HooksConfig`. - `core/src/hook_runtime.rs` adds the `plugin` metric tag for `HookSource::Plugin`. - `core/config.schema.json` picks up the new `plugin_hooks` feature flag, and `core/src/plugins/manager_tests.rs` updates fixtures for the added plugin hook fields. --------- Co-authored-by: Codex <noreply@openai.com>
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.
