## Why The app-server watcher relocation leaves the generic filesystem watcher as the last watcher-specific implementation still living inside `codex-core`. Moving that code to a small crate keeps `codex-core` focused on thread execution and lets app-server depend on the watcher without reaching back into core for filesystem watching primitives. This PR is stacked on #21287. ## What changed - Added a new `codex-file-watcher` crate containing the existing watcher implementation and its unit tests. - Updated app-server `fs_watch`, `skills_watcher`, and listener state to import watcher types from `codex-file-watcher`. - Removed the `file_watcher` module and `notify` dependency from `codex-core`. - Updated Cargo workspace metadata and `Cargo.lock` for the new internal crate. ## Validation - `cargo check -p codex-file-watcher -p codex-core -p codex-app-server` - `cargo test -p codex-file-watcher` - `cargo test -p codex-app-server skills_changed_notification_is_emitted_after_skill_change` - `just bazel-lock-update` - `just bazel-lock-check` - `just fix -p codex-file-watcher` - `just fix -p codex-core` - `just fix -p codex-app-server`
npm i -g @openai/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.
