## Why Reasoning summaries can contain an empty HTML comment placeholder, `<!-- -->`, when a generated summary part has no prose. The TUI treated that placeholder as visible summary content, so it leaked into both the completed conversation history and persisted transcript. Multi-part empty summaries could also leave later generated status headings visible as orphaned transcript content. ## What - Strip the empty reasoning-summary placeholder at the shared `ReasoningSummaryCell` boundary. - Suppress the cell when removing placeholders leaves only generated bold status headings. - Cover the multi-part placeholder-only shape with a rendering regression test for both normal history and transcript output. ## How to Test 1. Start Codex TUI with reasoning summaries visible, for example with `hide_agent_reasoning = false` and `model_reasoning_summary = "detailed"`. 2. Run a turn that receives an empty generated reasoning-summary part. 3. Confirm that the in-progress status heading may appear while the turn is running, but the completed history and transcript contain neither literal `<!-- -->` tokens nor orphaned reasoning headings. 4. Confirm that a reasoning summary with actual prose still renders normally. The model output is nondeterministic, so the targeted regression covers the exact multi-part placeholder shape from the report: - `just test -p codex-tui reasoning_summary_block_hides_empty_html_comment_parts`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
