pi-codex-usage

Minimal zero-configuration Pi extension for showing primary ChatGPT Codex usage limits in the statusline

This repository is a minimal fork of narumiruna/pi-extensions/extensions/pi-codex-usage. It keeps the auth and quota-fetching path, but intentionally narrows the interface to the primary Codex 5-hour and weekly limits.

Features

• Shows an empty statusline bar immediately, then refreshes every 30 seconds while the active Pi model uses openai-codex
• Statusline output stays compact, with the active usage label accented and the quota bar plus weekly reset countdown drawn on a themed background
• Regular Codex subscription models show the primary codex quota bucket
• GPT-5.3-Codex-Spark shows the parallel Spark quota bucket with the spark label
• When pi-telegram is available, the same compact value appears as codex: <value> or spark: <value> in the /start menu status text for active OpenAI Codex subscription models
• Additional returned buckets unrelated to the active Codex/Spark model are ignored
• Pi OpenAI Codex provider auth is used first
• Codex CLI app-server remains available as a fallback
• Missing auth, subscription, plan, or quota windows are shown as n/a, not as an error
• Successful updates briefly redraw the bar only when a 5% segment changes
• Network/provider failures keep the last good bar briefly, then show error
• No commands or configuration are required

Install

From npm:

pi install npm:@llblab/pi-codex-usage

From git:

pi install git:github.com/llblab/pi-codex-usage

Statusline

Regular Codex usage:

codex ██████▀▀▀▀ 6d

Spark model usage:

spark ██████████ 7d

The ten-character bar encodes two twenty-step limits at once: 40 total bits of quota state in 10 terminal cells. Each step is 5%: the top quadrants are the 5-hour limit, and the bottom quadrants are the weekly limit. If either quota window is exhausted, the bar keeps the same shape but switches to the error background color.

When the weekly reset time is available, the bar is followed by a countdown. More than a day remains is shown in 144-minute day-tenth steps such as 7d, 6.9d, 6.6d, 5.1d, 5d, 3.7d, 3d, 2d, 1.9d, 1.5d, and 1.1d, rounded upward to the next tenth. At 24 hours and below it switches to upward-rounded 6-minute hour-tenth steps such as 24h, 23.7h, 20.1h, 20h, 19.9h, 1.4h, 1.3h, 1.2h, 1.1h, and 1h. Under an hour it switches to floored minutes, and under a minute to seconds. After the reset timestamp passes, 0s is held until the next successful quota refresh reports the new weekly window.

When the 5-hour window is exhausted and exposes its own reset time, the statusline adds the 5-hour reset before the weekly reset:

codex ▄▄▄▄▄⠀⠀⠀⠀⠀ 5h/7d

The ten-character dual bar stays unchanged. The first countdown is the 5-hour reset, and the second countdown after / is the weekly reset.

Unavailable because Codex auth or subscription quota is not available:

codex n/a

Runtime failure, such as a network or provider error:

codex error

Telegram Status Menu

If @llblab/pi-telegram is loaded with the public status-line provider API, this extension registers an optional /start menu status row. The row is shown only while the active model uses the OpenAI Codex subscription provider:

codex: ██████▀▀▀▀ 6d
spark: ██████████ 7d

The value is the same compact quota bar plus weekly reset countdown used by the terminal statusline, and the label follows the active Codex/Spark model. If pi-telegram is absent, older, or the active model is not a Codex subscription model, no Telegram row is added.

Auth

The extension tries usage sources in this order:

1. Pi's openai-codex provider auth
2. codex app-server --listen stdio://

OpenAI API keys are not ChatGPT Codex subscription auth and do not expose these quotas.
