CLI tool to check Antigravity AI usage quotas

agcheck 🚀

A simple CLI tool to check your Antigravity AI usage quotas directly from the terminal.

Based on CodexBar implementation.

Installation

pip install agcheck

Requirements

• Python 3.7+
• macOS (uses lsof for port detection)
• Antigravity app must be running

Usage

# Check your current usage
agcheck

# Watch mode - live updates every 5 seconds
agcheck -w

# Watch mode with custom interval (10 seconds)
agcheck -w -i 10

# Compact output format
agcheck -c

# JSON output for scripting
agcheck --json

# Disable colors (useful for piping)
agcheck --no-color

What it shows

• Account email and plan name
• Usage quotas for each AI model (Claude, Gemini, GPT, etc.)
• Visual progress bars with color coding:
  • 🟢 Green: >70% remaining
  • 🟡 Yellow: 30-70% remaining
  • 🔴 Red: <30% remaining
• Reset time countdown for each model

Example output

╔══════════════════════════════════════════════════════╗
║      🚀 ANTIGRAVITY TOKEN USAGE CHECKER              ║
╚══════════════════════════════════════════════════════╝

  Model Quotas:

  Claude Sonnet 4.5                  
    [████████████████░░░░]  80.0% remaining | 20.0% used ↻ 4h 25m

  Gemini 3 Flash                     
    [████████████████████] 100.0% remaining | 0.0% used ↻ 4h 26m

How it works

1. Detects the Antigravity language server process
2. Extracts the CSRF token from the process command line
3. Discovers listening TCP ports using lsof
4. Connects to the local API (HTTPS with self-signed cert)
5. Fetches and displays quota information
