## Summary Fixes #18160. iTerm2 can append the current foreground process to tab titles, and Codex's terminal-title updates were causing that decoration to appear as `(codex")` with a stray trailing quote. Codex was writing OSC 0 title sequences terminated with ST (`ESC \`). Some terminal title integrations appear to accept that title update but still expose the ST terminator in their own process/title decoration. ## Changes - Update `codex-rs/tui/src/terminal_title.rs` to terminate OSC 0 title updates with BEL instead of ST. - Update the focused terminal-title encoding test to assert the BEL-terminated sequence. ## Compatibility This should be low risk: the title payload and update timing are unchanged, and BEL is the form already emitted by `crossterm::terminal::SetTitle` in the crossterm version used by this repository. BEL is also the widely supported xterm-family title terminator used by common terminals and multiplexers. The main theoretical risk would be a very old or unusual terminal that accepted only ST and not BEL for OSC title termination, but that is unlikely compared with the observed iTerm2 issue. ## Verification - `cargo test -p codex-tui terminal_title` - `cargo test -p codex-tui`
npm i -g @openai/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.
