Browser Search Tool for GAIA
This module provides a dedicated Browser Search Tool implementation with proper
Supabase memory integration. It allows for searching websites directly using
browser_action capabilities and storing the results in the agent's memory.
The tool provides methods for:
- Searching specific websites (Wikipedia, YouTube, etc.)
- Determining the best site based on query content
- Storing search results and browser interactions in memory
- Error handling and detailed logging
All operations properly integrate with Supabase working memory, ensuring results
are persistently stored and retrievable for agent continuity.
