## Why Users need to understand what external-agent data Codex detected, what is selected, and how to proceed before an import begins. The updated picker makes focus, selection state, and the submission path explicit while preserving the existing import backend. ## What changed - replace the old migration prompt with a two-step external-agent import picker - add a customize view with explicit item focus, selection state, counts, and a review action - separate detected import data into a view model - add Unix and Windows snapshots for prompt, item-focus, and action-focus states ## Validation - `just test -p codex-tui external_agent_config_migration` (10 passed) - manually exercised an isolated TUI fixture covering customization, selection toggles, review, import, repeated invocation, and session resume - the broader `just test -p codex-tui` run passed 2,805 tests, with 2 unrelated guardian feature-flag failures and 4 skipped tests ## Review note This is the largest layer in the stack because the interaction state, rendering changes, and required snapshots move together. It remains a draft in case reviewers prefer a further presentation/state split. ## 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 3.** 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.
