Semantic Release / release (push) Has been cancelled
Implements a new provider that uses Google's Antigravity unified gateway API to access Claude, Gemini, and other models through a single OAuth2-authenticated endpoint. Features: - OAuth2 token management with automatic refresh - Multi-account rotation for rate limit distribution - Support for Claude Opus/Sonnet 4.5 (with/without thinking) - Support for Gemini 2.5/3 models (Pro/Flash variants) - Thinking mode support with configurable tokens - Image processing support - Dual quota pool tracking (antigravity vs gemini-cli) - Gemini-style API request format Authentication: - Reads from ANTIGRAVITY_REFRESH_TOKEN env var (priority) - Falls back to ~/.config/opencode/antigravity-accounts.json - Automatic token refresh with retry logic - Rate limit tracking per account and quota pool Files added: - providers/antigravity.py - Main provider implementation - providers/antigravity_auth.py - OAuth token manager - providers/registries/antigravity.py - Model registry - conf/antigravity_models.json - Model definitions (11 models) - docs/antigravity_provider.md - Setup and usage docs - tests/test_antigravity_provider.py - Unit tests (14 pass) Integration: - Added to provider priority order after ZEN - Registered in server.py with auto-detection - ToS warning logged on first use
