## Why Thread-scoped config needs a stable boundary between the app/session owner and the config stack. Instead of having call sites manually copy thread config fields into individual overrides, this adds the proto and Rust plumbing needed for a `ThreadConfigLoader` implementation to return typed sources that can be translated into ordinary config layer entries. Keeping the remote payload typed also makes precedence easier to reason about: session-owned thread config maps back to the existing session config source, while user-owned thread config is represented separately without introducing a new config-layer source until it has TOML-backed fields. ## What changed - Added the `codex.thread_config.v1` protobuf service and generated Rust module for loading thread config sources. - Added `RemoteThreadConfigLoader`, which calls the gRPC service, parses `SessionThreadConfig` / `UserThreadConfig`, and validates provider fields such as `wire_api`, auth timeout, and absolute auth cwd. - Added proto generation tooling under `config/scripts/generate-proto.sh` and `config/examples/generate-proto.rs`. - Added `ThreadConfigLoader::load_config_layers`, plus static/no-op loader helpers, so tests and callers can use the same typed loader interface while config-layer translation stays centralized. ## Verification - `cargo test -p codex-config thread_config`
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.
