## Summary - Remove `perCwdExtraUserRoots` / `SkillsListExtraRootsForCwd` from the `skills/list` app-server API. - Drop Rust app-server and `codex-core-skills` extra-root plumbing so skill scans are keyed by the normal cwd/user/plugin roots only. - Regenerate app-server schemas and update docs/tests that only existed for the removed extra-roots behavior. ## Validation - `just write-app-server-schema` - `just fmt` - `cargo test -p codex-app-server-protocol` - `cargo test -p codex-core-skills` - `just fix -p codex-app-server-protocol` - `just fix -p codex-core-skills` - `just fix -p codex-app-server` - `just fix -p codex-tui` ## Notes - `cargo test -p codex-app-server --test all skills_list` ran the edited skills-list cases, but the full filtered run ended on existing `skills_changed_notification_is_emitted_after_skill_change` timeout after a websocket `401`. - `cargo test -p codex-tui --lib` compiled the changed TUI callers, then failed two unrelated status permission tests because local `/etc/codex/requirements.toml` forbids `DangerFullAccess`. - Source-truth check found the OpenAI monorepo still has generated/app-server-kit mirror references to the removed field; those should be cleaned up when generated app-server types are synced or in a companion OpenAI cleanup.
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.
