## Why Fixes #16688. The TUI currently hydrates collab receiver metadata by awaiting `thread/read` before each active-thread notification is rendered. During large subagent fan-outs, the embedded app-server can be busy starting agents and processing spawn work, so those synchronous metadata reads queue behind the fan-out and block the TUI event loop. That makes the UI appear frozen even though the underlying agent work can continue. ## What Changed - Replaced eager `thread/read` metadata hydration on the active notification path with local receiver-thread caching. - Kept `ThreadStarted` and picker refreshes as the places that fill in agent nickname/role metadata when it is available. - Skipped caching receiver threads that are explicitly reported as `NotFound`, avoiding live-looking ghost entries for failed stale-agent calls. - Added TUI tests covering both local receiver caching and `NotFound` suppression. ## Verification - `cargo test -p codex-tui collab_receiver_notification` - `just fix -p codex-tui` I also ran the full `cargo test -p codex-tui`; the new test passed, but the full process later aborted with an unrelated stack overflow in `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
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.
