Zai Quota

OpenCode TUI plugin that shows your Z.AI coding plan quota (zai-coding-plan) directly in the sidebar: a gauge for the short usage window and one for the plan-level allowance, with live colors as you approach the limits.

Features

• Panel in the session sidebar with one gauge per quota limit:
  • Bar (26 cells) filled according to consumption percentage.
  • Dynamic colors: green < 70%, yellow 70-89%, red >= 90%.
  • Reset countdown per limit (from nextResetTime).
  • Usage / allowance numbers, plan level, and last-refresh time in the header.
• Compact zai:N% chip next to the session prompt input.
• Refreshes every minute, on session.idle, and on demand via the /zai-quota command (also in the command palette, ctrl+p).
• Colors read from the active OpenCode theme (api.theme.current.*) — no hardcoded hex values.

Install

OpenCode TUI plugins are not auto-discovered: installing the package only downloads it — the plugin must also be registered in tui.json. Two ways:

Option 1 — Plugin manager inside OpenCode (recommended)

1. npm install -g opencode-zai-quota
2. Open OpenCode, press ctrl+p and run plugin install (or open the plugin manager and add opencode-zai-quota).
3. The plugin manager writes the entry to tui.json for you. Restart OpenCode.

Option 2 — Manual registration

1. npm install -g opencode-zai-quota
2. Add the plugin to ~/.config/opencode/tui.json (a project-level .opencode/tui.json also works):

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": ["opencode-zai-quota"]
}

1. Restart OpenCode. The Z.AI PLAN panel appears in the session sidebar and the zai:N% chip next to the prompt input.

Editing tui.json requires a restart: config is not hot-reloaded. Unknown top-level keys in tui.json are rejected and will crash startup — keep the shape shown above.

Authentication

The token is read automatically from OpenCode's own credentials (~/.local/share/opencode/auth.json): the zai-coding-plan entry first, then zai. If you can chat with a zai-coding-plan model in OpenCode, the widget works with zero configuration.

Environment fallbacks: ZAI_TOKEN / Z_AI_TOKEN.

Data source

Commands

Slash command	Palette title	Description
/zai-quota (/zq)	Z.AI quota: refresh now	Force a refresh and show a toast with the result

Note

This is a community plugin, not affiliated with Z.AI or OpenCode.

Freeze guard (v1.0.2)

When the Z.AI provider kills a stream with Weekly/Monthly Limit Exhausted, the turn used to hang in the TUI (looking frozen). The plugin now listens for the session.error event, shows an error toast with the reset time, refreshes the gauges, and aborts the stuck turn automatically so the UI unfreezes immediately. Switch model with /models to keep working until the reset.
