Use when the user wants thorough research, a literature review, a competitive scan, or says "deep research", "research this properly", "build me a research doc".

Conducts in-depth analysis of a specific source or topic, producing a comprehensive, information-dense summary for research synthesis. Use when detailed analysis and documentation of an individual source is needed as part of a larger research effort. Primarily used by the research-analyst agent inside the deep-research workflow.
