# Summary When a user finishes planning, the TUI asks whether to implement in the current conversation or start fresh with the approved plan. The clear-context choice is easier to evaluate when the prompt shows how much context has already been used, because the user can see when carrying the full prior conversation is likely to be less useful than preserving only the plan. <img width="1612" height="1312" alt="image" src="https://github.com/user-attachments/assets/694bcf87-8be5-4e88-a412-e562af62d5f7" /> This PR adds that context signal directly to the clear-context option while keeping the copy compact enough for the Plan-mode selection popup. # What Changed - Compute an optional context-usage label when opening the plan implementation prompt. - Show the label only on `Yes, clear context and implement`, where it informs the cleanup decision. - Prefer a percentage-used label when context-window information is available, with a compact token-used fallback when only token totals are known. - Preserve the original option description when usage is unknown or effectively zero. - Add rustdoc comments around the prompt-copy boundary so future changes keep the context label formatting and selection rendering responsibilities clear. # Testing - `cargo test -p codex-tui plan_implementation` # Notes The footer continues to show context remaining as ambient status. The implementation prompt intentionally shows context used because the user is choosing whether to clean up the current thread before implementation.
npm i -g @openai/codex
or brew install --cask codex
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.
