antigravity-balance
Check Google Antigravity AI model quota/token balance. Use when a user asks about their Antigravity usage, remaining tokens, model limits, quota status, or rate limits. Works by detecting the local Antigravity language server process and querying its API.
Why this skill is useful
Adds an executable script that queries the local Antigravity API for user quota and token balance, which is not publicly documented.
What it needs
Requires node installed locally. Requires antigravity account access. About 1k tokens when loaded. Last updated 2026-03-07. 639 stars on the source repository.
What this skill does
Antigravity Balance Check your Antigravity AI model quota and token balance. Quick Start How It Works 1. Process Detection: Finds the running languageservermacosarm (or platform equivalent) process 2. Extracts Connection Info: Parses --extensionserverport and --csrftoken from process args 3. Port Discovery: Scans nearby ports to find the HTTPS API endpoint (typically extensionPort + 1) 4. Queries Local API: Hits https://127.0.0.1:{port}/exa.languageserverpb.LanguageServerService/GetUserStatus 5. Displays Quota: Shows remaining percentage, reset time, and model info Output Format Default output shows: User name, email, and tier Model name and remaining quota percentage Visual progress bar (color-coded: green >50%, yellow >20%, red ≤20%) Reset countdown (e.g., "4h 32m") JSON output (--json) returns structured data: Requirements Node.js (uses built-in https module) Antigravity (or Windsurf) must be running Troubleshooting If the script fails: 1. Ensure Antigravity/Windsurf is running 2. Check if the language server process exists: ps aux grep languageserver 3. The process must have --appdatadir antigravity in its args (distinguishes from other Codeium forks) Platform-Specific Process Names Platform Process Name ---------- -------------- macOS (ARM) languageservermacosarm macOS (Intel) languageservermacos Linux languageserverlinux Windows languageserverwindowsx64.exe
