## Why With the local model layer and app-server routing in place from PR1, this PR moves the active TUI runtime onto app-server notifications. The affected pieces share the same event flow, so the command surface, session state, bottom-pane prompts, chat rendering, history/status views, and tests move together to keep the stacked branch buildable. This PR also removes the obsolete compatibility surface that is no longer used after the migration. The proposed protocol-boundary verifier layer was dropped from the stack; enforcing that final boundary will be simpler once `codex-tui` no longer needs any `codex_protocol` references. This PR is part 2 of a 2-PR stack: 1. Add TUI-owned replacement models and extract app-server event routing. 2. Move the active TUI flow to app-server notifications and delete obsolete adapter code. ## What changed - Rewired app command and session handling to use app-server request and notification shapes. - Moved approval overlays, request-user-input flows, MCP elicitation, realtime events, and review commands onto the app-server-facing model surface. - Updated chat rendering, history cells, status views, multi-agent UI, replay state, and TUI tests to use app-server notifications plus the local models introduced in PR1. - Deleted `codex-rs/tui/src/app/app_server_adapter.rs` and the superseded `chatwidget/tests/background_events.rs` fixture path. ## Verification - `cargo check -p codex-tui --tests` - Top of stack: `cargo test -p codex-tui`
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.
