codex-statusline

See your Codex context and quota at a glance.

English | 简体中文

A status bar for OpenAI Codex CLI. It shows context used, 5-hour and weekly quota left with reset times, and session tokens. You keep running codex exactly as before.

CTX USED ███░░░░░ 35% | 5h ████████░░ 78% 5:41pm | week ████░░░░░░ 39% Fri 3:41pm | tok 1.2M

Why

• No more /status interruptions. Quota and context sit in view while you work.
• Local only. Never reads auth.json, never calls a quota API, never makes extra model calls.
• Zero new habits. Keep typing codex. codex exec, pipes, and scripts pass straight through to the official binary.
• Honest numbers. Unknown shows as -- and stale quota shows as refresh. A missing value is never passed off as 0% or 100%.
• Fits any width. Segments collapse, then drop, as the terminal narrows.

Install

Requires macOS or Linux, tmux, and Codex CLI ≥ 0.159.0. Bash, Zsh, and Fish are all detected automatically.

curl -fsSL https://raw.githubusercontent.com/Moviw/codex-statusline/main/install.sh | sh

The script installs uv if needed (uv also fetches Python 3.11+ for you), installs the tool, then shows you the exact shell/hook diff and asks before writing anything.

Prefer to do it yourself:

uv tool install codex-statusline    # or: pipx install codex-statusline
codex-statusline install            # add --dry-run to only preview the diff

Then open a new terminal and run codex. The first time, Codex asks you to review a hook: confirm it is codex-statusline binding.

Missing tmux? brew install tmux or sudo apt install tmux.

Usage

codex                     # same as always, now with a status bar
codex resume --last
codex exec 'task'         # non-interactive: passed straight through, no bar

codex-statusline doctor   # check versions and dependencies
codex-statusline preview --demo --width 80   # try it without launching Codex
codex-statusline uninstall

Uninstall removes only what this tool added and still matches exactly. If you edited its block, it stops instead of overwriting. Backups live in ~/.local/share/codex-statusline/.

Configuration

Optional. Create ~/.config/codex-statusline/config.toml:

segments = ["ctx", "5h", "week", "tokens"]  # pick and reorder
theme = "dark"     # dark | light
ascii = false      # true for terminals without block glyphs
warn_at = 20       # quota remaining % that turns yellow
crit_at = 5        # quota remaining % that turns red

Invalid values are reported and fall back to defaults.

How it works

codex becomes a small shell function that starts the official CLI inside a private tmux session and draws the bar at the bottom. Data comes from two places only: the terminal title Codex already emits (model, context, thread id), and the rollout log of this session, which a SessionStart hook pins by exact path. The official binary is not replaced or patched, and your tmux config is not touched. Details: docs/architecture.md.

FAQ

How do I scroll or copy? It runs inside tmux: press Ctrl-B then [ to scroll and copy. The mouse wheel may behave differently from bare Codex.

Windows? Not supported (tmux).

Is this official? No. It is a third-party tool built on a version-sensitive integration.
