  Claude Code (Max Plan)

  ✅ Connected
  5h Window:  1.0% used (99.0% left) → resets in 4h 56m
  7d Window:  56.0% used (44.0% left) → resets in 2d 17h

  Antigravity CLI
════════════════════════════════════════
  ✅ Connected
  Tier: Google AI Ultra
  Project: melodic-component-26v41

  Gemini Models
    Weekly Limit:      0.0% used → resets in 6d 23h
    Five Hour Limit:   0.0% used → resets in 4h 59m

  Claude and GPT models
    Weekly Limit:     93.0% used → resets in 2d 20h
    Five Hour Limit:  95.0% used → resets in 19m

Antigravity usage matches the desktop app's "Weekly Limit" / "Five Hour Limit" readouts. Models are grouped (Gemini vs. Claude/GPT); within a group the weekly and five-hour windows are shared. Reported as % used, like the app.

Tier note: loadCodeAssist returns two tiers. currentTier is the Cloud Code Assist API tier — always free-tier for consumer (non-GCP) accounts, regardless of any Google One AI subscription. paidTier carries the real subscription (e.g. Google AI Ultra) and only appears when one exists, so the tool prefers it. The raw API tier is still available as api_tier_id in --json output. Accounts with no Google One AI plan correctly show Antigravity (free-tier).

JSON Output (for AI agents)

aichecker --json

Returns structured JSON with all limits, remaining percentages, and reset times. AI agents (Hermes, Claude Code, etc.) can parse this to plan task delegation.

Supported Tools

Tool	Metrics
Claude Code	5h window, 7d window, Sonnet/Opus breakdown
Antigravity CLI	Per-group weekly + five-hour limits, % used, reset time

How It Works

• Claude Code: Reads ~/.claude/.credentials.json (Windows/Linux) or macOS Keychain, calls api.anthropic.com/api/oauth/usage
• Antigravity: Reads Windows Credential Manager (gemini:antigravity) or ~/.gemini/oauth_creds.json, calls cloudcode-pa.googleapis.com

No credentials are sent anywhere except the official API endpoints of each tool.
