Features

Real-Time Quota Monitoring

• Automatic detection – Finds Antigravity's language server process, port, and auth token without manual setup
• Background polling – Periodically fetches quota data to keep the status bar up-to-date
• Multi-model support – Tracks quota usage for all available AI models (Gemini, Claude, GPT, etc.)

Status Bar Integration

• Displays quota info directly in the VS Code status bar
• Visual indicators:
  • $(check) – Quota healthy (>20%)
  • $(warning) – Quota low (<20%)
  • $(error) – Quota exhausted
• Click to open the interactive quota menu

Pinned Models

• Pin your favorite models to the status bar for quick visibility
• Toggle pinning from the interactive menu
• When no models are pinned, displays "AGQ" as default

Interactive Quota Menu

• View all models with progress bars and percentages
• See time until quota reset for each model
• View prompt credits (available/monthly)
• Toggle model visibility directly from the menu

Cross-Platform Support

• Windows – Full support using wmic for process detection
• macOS – Unix-based detection strategy
• Linux – Unix-based detection strategy

Commands

| Command | Description | | ------------------ | --------------------------- | | AGQ: Refresh Now | Manually refresh quota data |

How It Works

1. Process Detection – Scans for Antigravity's language server process and extracts connection parameters
2. Port Discovery – Tests listening ports to find the correct API endpoint
3. Quota Fetching – Calls GetUserStatus API to retrieve model quotas and prompt credits
4. UI Updates – Parses the response and updates the status bar with formatted quota info

This extension was created by me and Gemini 3 Pro between some Rainbow Six Siege Games, therefore please do not expect the highest code quality in this repo (yet). Some parts of the code (and especially the knowledge of how this process works) are based on the Antigravity Quota Watcher project.
