Add a centralized FileWatcher in codex-core (using notify) that watches skill roots from the config layer stack (recursive) Send `SkillsChanged` events when relevant file system changes are detected On `SkillsChanged`: * Invalidate the skills cache immediately in ThreadManager * Emit EventMsg::SkillsUpdateAvailable to active sessions ~~* Broadcast a new app-server notification: SkillsListUpdatedNotification~~ This change does not inject new items into the event stream. That means the agent will not know about new skills, so it won't be able to implicitly invoke new skills. It also won't know about changes to existing skills, so if it has already read the contents of a modified skill, it will not honor the new behavior. This change also does not detect modifications to AGENTS.md. I plan to address these limitations in a follow-on PR modeled after #9985. Injection of new skills and AGENTS was deemed to risky, hence the need to split the feature into two stages. The changes in this PR were designed to easily accommodate the second stage once we have some other foundational changes in place. Testing: In addition to automated tests, I did manual testing to confirm that newly-created skills, deleted skills, and renamed skills are reflected in the TUI skill picker menu. Also confirmed that modifications to behaviors for explicitly-invoked skills are honored. --------- Co-authored-by: Xin Lin <xl@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 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.
