This PR replaces the TUI’s file-only `@mention` popup with a unified mentions experience. Typing `@...` now searches across filesystem matches, installed plugins, and skills in one popup, with result types clearly labeled and selectable from the same flow. - Adds a unified `@mentions` popup that returns: - plugins - skills - files - directories - Adds search modes so users can narrow the popup without changing their query: - All Results _(default/same as Codex App)_ - Filesystem Only - Plugins _(...and skills)_ - Preserves existing insertion behavior: - selected file paths are inserted into the prompt - paths with spaces are quoted - image file selections still attach as images when possible - selecting a plugin or skill inserts the corresponding `$name` - the composer records the canonical mention binding, such as `plugin://...` or the skill path - Expanded `@mentions` rendering: - type tags for Plugin, Skill, File, and Dir - distinct plugin/filesystem colors - stable fixed-height layout (8 rows) - truncation behavior for narrow terminals Note: - The unified mentions popup does not display app connectors under `@mention` results for Codex App parity. Connector mentions remain available through the existing `$mention` path. https://github.com/user-attachments/assets/f93781ed-57d3-4cb5-9972-675bc5f3ef3f

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.
