## Why Skills update notifications are app-server API behavior, but the watcher lived in `codex-core` and surfaced through `EventMsg::SkillsUpdateAvailable`. Moving the watcher out keeps core focused on thread execution and lets app-server own both cache invalidation and the `skills/changed` notification. ## What changed - Added an app-server-owned skills watcher that watches local skill roots, clears the shared skills cache, and emits `skills/changed` directly. - Registers skill watches from the common app-server thread listener attach path, including direct starts, resumes, and app-server-observed child or forked threads. - Stores the `WatchRegistration` on `ThreadState`, so listener replacement, thread teardown, idle unload, and app-server shutdown deregister by dropping the RAII guard. - Removed `EventMsg::SkillsUpdateAvailable`, the core watcher, and the old core live-reload test. - Extended the app-server skills change test to verify a cached skills list is refreshed after a filesystem change without forcing reload. ## Validation - `cargo check -p codex-core -p codex-app-server -p codex-mcp-server -p codex-rollout -p codex-rollout-trace` - `cargo test -p codex-app-server skills_changed_notification_is_emitted_after_skill_change`
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.
