• Antigravity-Tools-LS: A Language Server Protocol (LSP) designed for AI protocols, providing you with smarter code completion, diagnostics, and protocol debugging experiences.

🌟 Detailed Feature Matrix

1. 🎛️ Smart Account Dashboard

• Global Real-time Monitoring: Instant insight into the health of all accounts, including average remaining quotas for Gemini Pro, Gemini Flash, Claude, and Gemini Image generation.
• Smart Recommendation: The system uses a real-time algorithm to filter and recommend the "Best Account" based on quota redundancy, supporting one-click switching.
• Active Account Snapshot: Visually displays the specific quota percentage and the last synchronization time of the currently active account.

2. 🔐 Powerful Account Management

• OAuth 2.0 Authorization (Auto/Manual): Pre-generates a copyable authorization URL so you can finish auth in any browser; after the callback, the app auto-completes and saves the account (use “I already authorized, continue” if needed).
• Multi-dimensional Import: Supports single token entry, JSON batch import, and automatic hot migration from V1 legacy databases.
• Gateway-level Views: Supports switching between "List" and "Grid" views. Provides 403 Forbidden detection, automatically marking and skipping accounts with permission anomalies.

3. 🔌 Protocol Conversion & Relay (API Proxy)

• Multi-Protocol Adaptation (Multi-Sink):
  • OpenAI Format: Provides /v1/chat/completions endpoint, compatible with 99% of existing AI apps.
  • Anthropic Format: Provides native /v1/messages interface, supporting all features of Claude Code CLI (e.g., chain-of-thought, system prompts).
  • Gemini Format: Supports direct calls from official Google AI SDKs.
• Smart Self-healing: When a request encounters 429 (Too Many Requests) or 401 (Expired), the backend triggers millisecond-level automatic retry and silent rotation, ensuring business continuity.

4. 🔀 Model Router Center

• Series-based Mapping: Classify complex original model IDs into "Series Groups" (e.g., routing all GPT-4 requests uniformly to gemini-3-pro-high).
• Expert Redirection: Supports custom regex-level model mapping for precise control over every request's landing model.
• Tiered Routing [New]: Automatically prioritizes models based on account tiers (Ultra/Pro/Free) and reset frequencies to ensure stability for high-volume users.
• Silent Background Downgrading [New]: Intelligently identifies background tasks (e.g., Claude CLI title generation) and reroutes them to Flash models to preserve premium quota.

5. 🎨 Multimodal & Imagen 3 Support

• Advanced Image Control: Supports precise control over image generation tasks via OpenAI size (e.g., 1024x1024, 16:9) parameters or model name suffixes.
• Enhanced Payload Support: The backend supports payloads up to 100MB (configurable), more than enough for 4K HD image recognition and processing.
