Researcher agents are specialized reasoning units designed for Deep Haystack Extraction. Unlike a standard search, a Researcher agent doesn't just return links; it reads the content of 50+ documents (SharePoint, SQL, Web) simultaneously, identifies contradictions, and synthesizes a single, cited report. In 2026, this is powered by high-tier models with extended 'thought-budgets' that perform internal verification steps before responding.
Every claim made by a Researcher agent must be Groundable. The agent automatically appends [Ref 1, Ref 2] markers that link back to the exact paragraph in Dataverse or SharePoint. Using the 'Citations' tool is mandatory for enterprise-grade research to prevent hallucination in legal or technical workflows.
