What is the difference between Expand and Deep modes?

Expand mode iteratively refines queries based on previous results for exploration, while Deep mode performs parallel multi-query synthesis for exhaustive analysis.

What backends does the Deep Research skill use?

It primarily uses Tavily for AI-optimized search, while mandating the loading of Exa (neural/GitHub search) and Valyu (recursive research) for comprehensive discovery.

Does this skill require specific API keys?

Yes, it requires a TAVILY_API_KEY and an EXA_API_KEY to be configured in your environment or configuration files.

How does the smart stopping feature work?

The agent automatically stops searching when sources consistently agree (confidence threshold), when follow-up queries return redundant results, or when the maximum iteration limit is reached.

生产力与工作流

Conducts multi-mode web research and synthesis using Tavily, Exa, and Valyu for comprehensive information discovery.

The Deep Research skill transforms Claude into a sophisticated research agent capable of complex, iterative information gathering. By leveraging multiple backends like Tavily, Exa, and Valyu, it goes beyond simple search results to provide multi-query synthesis, automated query refinement, and smart stopping based on confidence thresholds. Whether performing a quick fact-check or a deep dive into technical documentation and market trends, this tool orchestrates parallel searches to deliver structured markdown reports complete with source analysis and research traces.
