dsh-antigravity

English | 简体中文

Google Antigravity / Cloud Code Assist model provider for DeepSeek Harness.

Provides Google OAuth authentication, multi-account pool scheduling, live quota monitoring, seamless failover, and full internationalization (i18n).

Credits: This project is built upon LiZhenNet/dsh-antigravity. Special thanks to the original author for the foundational integration work. This project extends it with multi-account pool scheduling, health awareness, automatic failover, and diagnostics.

Features

• Multi-Account Scheduling: Manage multiple Google accounts with automatic load-aware scheduling across active sessions. Preserves session affinity while providing seamless failover when quota is depleted or throttled.
• Live Quota Monitoring: Real-time visualization for Gemini and 3P (Claude / GPT) quota buckets, including 5-hour and weekly reset tracking.
• Model Support: Full support for gemini-3.8-flash, gemini-3.7-flash, claude-opus-4-6, claude-sonnet-4-6, etc., with customizable reasoning effort tiers.
• Diagnostics: Built-in structured diagnostics logging to easily inspect and resolve request errors.

Login & Authentication

Open Settings > Antigravity and click Login to authorize via Google OAuth. The settings page automatically refreshes your quota upon login. You can add multiple accounts in the settings view to configure a pool.

The plugin starts a loopback OAuth callback server at http://localhost:51121/oauth-callback. If your browser does not open automatically, run the CLI helper:

node "$DSH_HOME/profiles/web/node_modules/dsh-antigravity/bin/antigravity-login.mjs"

Credentials are saved at: $DSH_HOME/storages/antigravity-oauth.json.
