OpenCode plugin for Google Search via Antigravity Manager
npm install opencode-google-searchOpenCode plugin for Google Search via Antigravity Manager.
- Antigravity Manager running locally at http://127.0.0.1:8045
- The manager must support gemini-*-online model variants with built-in Google Search Grounding
Add to your opencode.json:
``json`
{
"plugin": [
"opencode-google-search"
]
}
Then install dependencies:
`bash`
cd ~/.config/opencode && bun install
Once installed, any model can call the google_search tool:
`
User: Search for the latest AI news
Assistant: [calls google_search(query="latest AI news")]
The tool returns search results with source citations embedded in the response.
Configure via environment variables:
| Variable | Default | Description |
|----------|---------|-------------|
| OPENCODE_SEARCH_BASE_URL | http://127.0.0.1:8045 | Antigravity Manager URL |OPENCODE_SEARCH_MODEL
| | gemini-3-flash-online | Model for search |OPENCODE_SEARCH_MAX_TOKENS
| | 8192 | Max output tokens |OPENCODE_SEARCH_TIMEOUT_MS
| | 60000 | Request timeout (ms) |
This plugin wraps Antigravity Manager's -online` model variants, which have built-in Google Search Grounding. When called:
1. The tool sends your query to the configured model
2. The model performs a Google Search and synthesizes results
3. Returns formatted results with citations
Web search results may contain untrusted content. The model treats retrieved content as potentially unsafe.
