    npm version License: MIT

    A reverse-engineered client for the Google Antigravity CLI (Agy / Code Assist), bundled as an opencode plugin. It adds OAuth authentication and a google-agy model provider so opencode can call Gemini, Claude, and GPT models through the Code Assist backend, plus web search, quota, and image tools.

    Features

    • Google OAuth 2.0 (PKCE) — browser authorization with automatic token refresh.
    • Model support — Gemini 3.7 / 3.6 / 3.5 / 3.1 Flash & Pro series, claude-sonnet-4-6, claude-opus-4-6-thinking, gpt-oss-120b-medium.
    • Tools:
      • agy_usage — inspect Code Assist quota and limits
      • websearch_cited — grounded web search with inlined citations and a Sources: list
      • read_url_content — fetch and clean page content
      • generate_image — image generation and editing
    • Native context compaction — protocol-aligned summarization and tool-call flattening.
    • Thinking-chain fidelity — streaming deduplication, signature self-healing, system-reminder stripping.
