## Project Overview
Antigravity Claude Proxy is a Node.js proxy server that exposes an Anthropic-compatible API backed by Antigravity's Cloud Code service. It enables using Claude models (`claude-sonnet-4-5-thinking`, `claude-opus-4-5-thinking`) with Claude Code CLI.
Antigravity Claude Proxy is a Node.js proxy server that exposes an Anthropic-compatible API backed by Antigravity's Cloud Code service. It enables using Claude models (`claude-sonnet-4-5-thinking`, `claude-opus-4-5-thinking`) and Gemini models (`gemini-3-flash`, `gemini-3-pro-low`, `gemini-3-pro-high`) with Claude Code CLI.
The proxy translates requests from Anthropic Messages API format → Google Generative AI format → Antigravity Cloud Code API, then converts responses back to Anthropic format with full thinking/streaming support.

**Constants:** All configuration values are centralized in `src/constants.js`:
- API endpoints and headers
- Model mappings
- Model mappings and model family detection (`getModelFamily()`, `isThinkingModel()`)
- OAuth configuration
- Rate limit thresholds
- Thinking model settings
**Model Family Handling:**
- `getModelFamily(model)` returns `'claude'` or `'gemini'` based on model name
- Claude models use `signature` field on thinking blocks
- Gemini models use `thoughtSignature` field on functionCall parts
- When Claude Code strips `thoughtSignature`, the proxy uses Google's `skip_thought_signature_validator` sentinel value
**Error Handling:** Use custom error classes from `src/errors.js`:
- `RateLimitError` - 429/RESOURCE_EXHAUSTED errors
- `AuthError` - Authentication failures
