## Why Thread names are app-server metadata now, backed by the thread store and sqlite state database. Keeping a core `SetThreadName` op plus a rollout `thread_name_updated` event made rename persistence live in the wrong layer and required historical replay support for an event that new app-server flows should not write. ## What changed - Removed `Op::SetThreadName` and `EventMsg::ThreadNameUpdated` from the core protocol and deleted the core handler path that appended rename events to rollouts. - Updated app-server `thread/name/set` so both loaded and unloaded threads write through thread-store metadata and app-server emits `thread/name/updated` notifications. - Updated local thread-store name metadata updates to write sqlite title metadata and the legacy thread-name index without appending rollout events. - Removed state extraction and rollout handling for the deleted thread-name event. ## Validation - `cargo test -p codex-app-server thread_name_updated_broadcasts` - `cargo test -p codex-app-server thread_name_set_is_reflected_in_read_list_and_resume` - `cargo test -p codex-thread-store update_thread_metadata_sets_name_on_active_rollout_and_indexes_name` - `cargo test -p codex-state` - `cargo check -p codex-mcp-server -p codex-rollout-trace` - `just fix -p codex-app-server -p codex-thread-store -p codex-state -p codex-mcp-server -p codex-rollout-trace` ## Docs No external documentation update is expected for this internal ownership change.
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.
