TUI: Render request_user_input results in history and simplify interrupt handling (#10064)
## Summary
This PR improves the TUI experience for `request_user_input` by
rendering submitted question/answer sets directly in conversation
history with clear, structured formatting.

It also intentionally simplifies interrupt behavior for now: on `Esc` /
`Ctrl+C`, the questions overlay interrupts the turn without attempting
to submit partial answers.

/>

## Scope
- TUI-only changes.
- No core/protocol/app-server behavior changes in this PR.
- Resume reconstruction of interrupted question sets is out of scope for
this PR.

## What Changed
- Added a new history cell: `RequestUserInputResultCell` in
`codex-rs/tui/src/history_cell.rs`.
- On normal `request_user_input` submission, TUI now inserts that
history cell immediately after sending `Op::UserInputAnswer`.
- Rendering includes a `Questions` header with `answered/total` count.
- Rendering shows each question as a bullet item.
- Rendering styles submitted answer lines in cyan.
- Rendering styles notes (for option questions) as `note:` lines in
cyan.
- Rendering styles freeform text (for no-option questions) as `answer:`
lines in cyan.
- Rendering dims only the `(unanswered)` suffix.
- Rendering can include an interrupted suffix and summary text when the
cell is marked interrupted.
- Rendering redacts secret questions as `••••••` instead of showing raw
values.
- Added `wrap_with_prefix(...)` in `history_cell.rs` for wrapped
prefixed lines.
- Added `split_request_user_input_answer(...)` in `history_cell.rs` for
decoding `"user_note: ..."` entries.

## Interrupt Behavior (Intentional for this PR)
- `Esc` / `Ctrl+C` in the questions overlay now performs `Op::Interrupt`
and exits the overlay.
- It does **not** submit partial/committed answers on interrupt.
- Added TODO comments in `request_user_input` overlay interrupt paths
indicating where interrupted partial result emission should be
reintroduced once core support is finalized.
- Queued `request_user_input` overlays are discarded on interrupt in the
current behavior.

## Tests Updated
- Updated/added overlay tests in
`codex-rs/tui/src/bottom_pane/request_user_input/mod.rs` to reflect
interrupt-only behavior.
- Added helper assertion for interrupt-only event expectation.
- Existing submission-path tests now validate history insertion behavior
and expected answer maps.

## Behavior Notes
- Completed question flows now produce a readable `Questions` block in
transcript history.
- Interrupted flows currently do not persist partial answers to
model-visible tool output.

## Follow-ups
- Reintroduce partial-answer-on-interrupt semantics once core can
persist/sequence interrupted `request_user_input` outputs safely.
- Optionally add replay/resume rendering for interrupted question sets
as a separate PR.

Codex CLI (Rust Implementation)

We provide Codex CLI as a standalone, native executable to ensure a zero-dependency install.

Installing Codex

Today, the easiest way to install Codex is via npm:

npm i -g @openai/codex
codex

You can also install via Homebrew (brew install --cask codex) or download a platform-specific release directly from our GitHub Releases.

Documentation quickstart

What's new in the Rust CLI

The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.

Config

Codex supports a rich set of configuration options. Note that the Rust CLI uses config.toml instead of config.json. See docs/config.md for details.

Model Context Protocol Support

MCP client

Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the configuration documentation for details.

MCP server (experimental)

Codex can be launched as an MCP server by running codex mcp-server. This allows other MCP clients to use Codex as a tool for another agent.

Use the @modelcontextprotocol/inspector to try it out:

npx @modelcontextprotocol/inspector codex mcp-server

Use codex mcp to add/list/get/remove MCP server launchers defined in config.toml, and codex mcp-server to run the MCP server directly.

Notifications

You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The notify documentation includes a detailed example that explains how to get desktop notifications via terminal-notifier on macOS. When Codex detects that it is running under WSL 2 inside Windows Terminal (WT_SESSION is set), the TUI automatically falls back to native Windows toast notifications so approval prompts and completed turns surface even though Windows Terminal does not implement OSC 9.

codex exec to run Codex programmatically/non-interactively

To run Codex non-interactively, run codex exec PROMPT (you can also pass the prompt via stdin) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the RUST_LOG environment variable to see more about what's going on.

Experimenting with the Codex Sandbox

To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:

# macOS
codex sandbox macos [--full-auto] [--log-denials] [COMMAND]...

# Linux
codex sandbox linux [--full-auto] [COMMAND]...

# Windows
codex sandbox windows [--full-auto] [COMMAND]...

# Legacy aliases
codex debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
codex debug landlock [--full-auto] [COMMAND]...

Selecting a sandbox policy via --sandbox

The Rust CLI exposes a dedicated --sandbox (-s) flag that lets you pick the sandbox policy without having to reach for the generic -c/--config option:

# Run Codex with the default, read-only sandbox
codex --sandbox read-only

# Allow the agent to write within the current workspace while still blocking network access
codex --sandbox workspace-write

# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
codex --sandbox danger-full-access

The same setting can be persisted in ~/.codex/config.toml via the top-level sandbox_mode = "MODE" key, e.g. sandbox_mode = "workspace-write".

Code Organization

This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:

  • core/ contains the business logic for Codex. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use Codex.
  • exec/ "headless" CLI for use in automation.
  • tui/ CLI that launches a fullscreen TUI built with Ratatui.
  • cli/ CLI multitool that provides the aforementioned CLIs via subcommands.
