Rasmus Rygaard 0b4f694347 Add remote thread config loader protos (#18892)
## 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.

Codex CLI splash


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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.

Using Codex with your ChatGPT plan
