Felipe Coury c6bcd27832 feat(tui): suggest plan mode from composer drafts (#19901)
## Summary

- suggest Plan mode when the current composer draft contains the
standalone word `plan`
- shares the Codex App heuristics for detection
- excludes things line `/plan` and the word plan in shell mode
- reuse the existing `Shift+Tab` mode cycle and add thread-scoped
dismissal with `Esc`
- replace the normal footer hint while the reminder is visible so the
statusline stays anchored

## Why

The desktop app already nudges users toward Plan mode when their draft
clearly signals planning intent. The TUI had the underlying `/plan` and
`Shift+Tab` flows, but no equivalent reminder at the moment the user was
most likely to benefit from them.

## Details

The reminder is shown only when Plan mode is available, the draft
contains standalone `plan`, the user is not already in Plan mode, the
composer is actionable, and the current thread has not dismissed the
reminder. Slash-command and shell-command drafts are excluded.

The first implementation used an extra composer row, but that moved the
statusline whenever the heuristic fired. This version keeps the layout
stable by rendering the reminder in the existing footer row instead.

## Validation

- `INSTA_UPDATE=always cargo test -p codex-tui
chatwidget::tests::plan_mode::plan_mode_nudge -- --nocapture`
- `just fmt`
- `just fix -p codex-tui`
- `./tools/argument-comment-lint/run.py -p codex-tui`
- `cargo insta pending-snapshots`
- `git diff --check`

npm i -g @openai/codex
or brew install --cask codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


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
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

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.
