Making Deep Research Pluggable: What NVIDIA AI-Q Skills Teach Us About Enterprise Agent Architecture
On May 20, 2026, NVIDIA published a technical article explaining how to package AI-Q’s deep-research capability as a “specialized skill” callable by agent harnesses such as Claude Code, Codex, and OpenCode. The key point is not merely that another AI tool exists, but that the design proposes a clearer separation for enterprise Agents: a general-purpose agent harness manages conversation, tool orchestration, code execution, and user interaction, while a specialized research backend handles multisource retrieval, planning, synthesis, citations, evaluation, and enterprise data governance. (NVIDIA Developer) 1. Background: Why Shouldn’t a General-Purpose Agent Perform Deep Research Directly? Harnesses such as Claude Code, Codex, and LangChain Deep Agents are effective interaction entry points for developers. They maintain conversations, invoke tools, execute code, and turn user intent into action chains. But when the task becomes “generate a cited research report from multiple enterprise documents, internal databases, external materials, and regulated data sources,” the complexity quickly grows from “call several tools” into “build a complete research pipeline.” NVIDIA explicitly notes that enterprise teams must address data access, authentication, query routing, prompt tuning, output evaluation, and citation fidelity, and that these concerns should not be reimplemented in every harness. (NVIDIA Developer) ...
What Did Tencent AI Leader Shunyu Yao Discuss in This Podcast?
Drawing on Latent Space’s interview with Shunyu Yao, this article reviews ReAct, Reflexion, Tree of Thoughts, memory, benchmarks, ACI, and Agent UX, and summarizes the importance of tools, environments, evaluation, and interface design when putting AI agents into practice.
