Controls research scope with depth (how deep) and breadth (how wide) parameters
Evaluates source reliability with detailed scoring (0-1) and reasoning
Prioritizes high-reliability sources (≥0.7) and verifies less reliable information
Generates follow-up questions to better understand research needs
Produces detailed markdown reports with findings, sources, and reliability assessments
Available as a Model Context Protocol (MCP) tool for AI agents
For now MCP version doesn't ask follow up questions
