## Why External-agent import should be discoverable and deliberate without blocking startup or claiming the public `codex [PROMPT]` CLI namespace. The slash command keeps the flow local to the interactive TUI and reuses the existing app-server import API. ## What changed - add the user-facing `/import` slash command - detect external-agent importable items only when the command is invoked - run imports through the embedded local app-server - show start and completion messages, refresh configuration, and block duplicate imports while one is pending - reject the flow for unsupported remote and local-daemon sessions ## Validation - `just test -p codex-tui external_agent_config_migration` (10 passed) - manually exercised an isolated TUI fixture with existing external-agent setup and session data using a fresh `CODEX_HOME` - verified picker customization, plugin and session detection, import completion, repeated invocation, and imported-session resume context - the broader `just test -p codex-tui` run passed 2,805 tests, with 2 unrelated guardian feature-flag failures and 4 skipped tests ## Draft follow-ups - review whether completion messaging should remain attached to the initiating chat if the user switches chats during an import - review shutdown semantics for an in-progress background import ## Stack 1. [#27064](https://github.com/openai/codex/pull/27064): remove the startup migration flow 2. [#27065](https://github.com/openai/codex/pull/27065): extract the picker renderer 3. [#27070](https://github.com/openai/codex/pull/27070): add the external-agent import picker UX 4. [#27071](https://github.com/openai/codex/pull/27071): expose the flow through `/import` **This PR is stack item 4.** Draft while the lower stack dependencies are reviewed.
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.
