Opencode Google Search Plugin

This plugin adds Google Search capabilities to Opencode using Gemini's Grounding feature.

Features

• Google Search: Perform searches using Gemini 1.5 Pro with grounding.
• Authentication: Uses Gemini CLI OAuth scheme (PKCE) for secure authentication.
• Result Formatting: Provides summarized answers with citations and source links.

Installation

Since this is a local plugin for now, you need to link it in your Opencode configuration.

1. Clone this repository or navigate to the directory.
2. Install dependencies and build:

   npm install
   npm run build

3. Add to your ~/.config/opencode/config.json:

   {
     "plugins": [
       "file:///absolute/path/to/opencode-google-search"
     ]
   }

Usage

Authentication

Before searching, you must authenticate with your Google account. Ensure your Google Cloud project has the Generative Language API enabled if you are using your own project, though the default client ID should work for personal accounts.

Run the google_login tool:

/google_login

This will generate an authentication URL. Open it in your browser, approve the access, and copy the code parameter from the redirected URL (even if the page fails to load).

Then run the tool again with the code:

/google_login code="YOUR_AUTH_CODE"

Search

Once authenticated, you can use the google_search tool:

/google_search query="latest news on AI"

Or just ask Opencode naturally: "Search Google for the latest news on AI."
