## Why Fixes #19814. The TUI's current `Worked for ...` timing behavior is a leftover from #9599. At that point, models could emit multiple assistant messages in one turn for preambles/commentary, but the TUI did not yet have a reliable signal that an assistant message was the final answer when it started streaming. To avoid showing an ever-growing elapsed time on each preamble separator, #9599 made the separator timer incremental by tracking elapsed time since the previous separator. That workaround is no longer the right model for the final completed-turn display. Since then, #16638 added protocol-native turn timing, including `duration_ms` on turn completion. With that cumulative duration available at the point where the TUI renders the completed-turn separator, the UI can show the actual turn duration directly instead of carrying per-separator timing state. ## What Changed - Thread `duration_ms` into `ChatWidget::on_task_complete` from both legacy `TurnCompleteEvent` handling and app-server `TurnCompleted` notifications. - Use `duration_ms` for the final `Worked for ...` separator, falling back to the status indicator timer only when the protocol duration is unavailable. - Keep mid-turn separators before later assistant text as plain visual dividers instead of clocked `Worked for ...` separators. - Remove the old incremental separator timer state and helper (`last_separator_elapsed_secs` / `worked_elapsed_from`). - Add a snapshot regression test for a turn that runs a command and then completes with a final answer, verifying the final separator uses the cumulative turn duration. ## Verification - `cargo test -p codex-tui final_worked_for_uses_cumulative_turn_duration_snapshot` - `just fix -p codex-tui` Manual repro prompt: ```text Manual timing repro. First send a short preamble/commentary sentence before using tools. Then run exactly this shell command: sleep 75; echo MANUAL_TIMING_DONE. After the command finishes, give a final answer that says "done". Do not skip the preamble. ``` After this change, the mid-turn break before the final answer should be a plain divider, and the final completed-turn separator should show `Worked for ...` using the cumulative turn duration.

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.
