OpenChamber Command Code Usage

A lightweight OpenChamber extension that displays Command Code usage directly inside OpenChamber.

Preview

Features

• Plan and account status
• Monthly usage, total allowance, percentage, remaining allowance, and period end
• 5-hour and weekly usage windows with percentages and reset times
• Billing-period requests, cost, input/output tokens, and success rate
• Manual refresh, one refresh when the panel opens, and refreshes every five minutes while it remains open

Requirements

• OpenChamber with Extension support
• Command Code CLI
• cmduse

macOS setup

npm i -g command-code@latest
cmd login
brew install JeffreyJYZ/tap/cmduse

Verify the CLI installation:

cmduse -1 --json

Installation

The repository includes the generated files required by OpenChamber. Git URL installation does not run npm install or build TypeScript for the extension, so panel/main.js and service/main.js are committed.

Install in OpenChamber

1. Open OpenChamber.
2. Go to Settings → Extensions.
3. Paste https://github.com/dai1012/openchamber-commandcode-usage.
4. Click Add.
5. Approve the local service permission.

How it works

OpenChamber panel
    ↓
extension local service
    ↓
cmduse -1 --json

The panel calls the extension's local service through the OpenChamber host. The service discovers and runs the local cmduse executable, then returns its parsed JSON response to the panel.

Privacy / Security

• The extension does not read ~/.commandcode/auth.json.
• The extension does not store a Command Code API key.
• Usage data comes only from the local cmduse -1 --json command.
• The local service listens only on localhost (127.0.0.1).
• The extension does not upload usage data to third-party servers.
• Child-process stdout/stderr is not returned when execution or JSON parsing fails.

Platform compatibility

Verified:

• macOS Apple Silicon
• OpenChamber 1.24.x

Other platforms may work when cmduse is available on PATH or configured through CMDUSE_PATH, but they are not claimed as verified here.

Development

The repository includes TypeScript sources, tests, and the generated files required by OpenChamber:

npm install
npm test
npm run build

panel/main.js is a browser IIFE. service/main.js is the Node service entrypoint required by the OpenChamber local-service contract.
