Codex Status

An OpenCode TUI plugin that shows your ChatGPT Codex quota in the session sidebar.

It reads your usage from the Codex CLI's own endpoint using credentials that opencode already stores. Checking quota does not consume any of your quota.

Installation

Install the plugin with OpenCode's native installer:

opencode plugin opencode-codex-status --global

Or via npx:

npx opencode-codex-status install

For project-local testing, use OpenCode's project scope:

opencode plugin opencode-codex-status

Or via npx:

npx opencode-codex-status install --project

Restart OpenCode after installing.

Usage

It uses the OpenAI credentials OpenCode already stores. No extra auth setup is needed.

Once loaded, the quota display appears in the TUI sidebar. Run /codex-status to force a refresh, or /codex-status-toggle to show/hide the display on the fly.

Configuration

The installer writes a plugin entry in tui.json. To change options, edit that entry:

{
  "plugin": [["opencode-codex-status", { "pollMs": 60000 }]]
}

Option	Default	Description
pollMs	300000	Polling interval in milliseconds
retryCount	1	Retries on transient failure
authPath	(auto)	Path to the auth JSON file
enabled	true	Start with the sidebar display hidden when false; toggle at runtime via /codex-status-toggle

How it works

The plugin fetches your Codex usage data on startup and periodically every 5 minutes (configurable). It also refreshes after each step completes.

Each quota window shows a label, a progress bar, remaining percent, and estimated time until reset. Error states and stale data are displayed inline.
