## Why `codex-rs/app-server-protocol/src/protocol/v2.rs` had grown into a single ~12k-line definition file for the entire app-server v2 API. This is purely a mechanical refactor to break up the monolithic `v2.rs` file that contains all app-server API v2 types into more modular files, grouped by resource (e.g. account, thread, turn, etc.). `just write-app-server-schema` shows no real changes, so we can be sure that this is purely an internal organizational change. ## What changed - Replaced the monolithic `protocol/v2.rs` with a `protocol/v2/` module tree and a small `mod.rs` that only declares and reexports modules. - Grouped v2 API definitions by conceptual owner, including `account`, `apps`, `collaboration_mode`, `command_exec`, `config`, `device_key`, `experimental_feature`, `feedback`, `fs`, `hook`, `item`, `mcp`, `model`, `notification`, `permissions`, `plugin`, `process`, `realtime`, `review`, `thread`, `thread_data`, `turn`, and `windows_sandbox`. - Moved v2 tests into `protocol/v2/tests.rs` so `mod.rs` stays small. - Kept shared protocol helpers in `protocol/v2/shared.rs`, including the enum mirroring macro and common cross-resource types. - Co-located resource-specific notifications and server-request payloads with the modules that own those resources. - Regenerated app-server protocol schema fixtures. The schema diffs are non-semantic newline-only changes after the refactor. ## Verification - `cargo check -p codex-app-server-protocol` - `cargo test -p codex-app-server-protocol` - `just write-app-server-schema`
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.
