Detailed Description

Deep Research agent — NeoGraph port of langchain-ai/open_deep_research.

A supervisor/researcher pattern: a lead agent plans research topics, fans out parallel researcher agents (each running its own ReAct loop against web-search tools), compresses their findings, and synthesises a final markdown report.

Unlike LangGraph's Python implementation, this runs as a single compiled C++ graph. The supervisor issues ConductResearch tool-calls which the dispatcher node converts into parallel Sends to a researcher node that embeds the LLM + tool loop inline.

Function Documentation

create_deep_research_graph()

std::unique_ptr< GraphEngine > neograph::graph::create_deep_research_graph	(	std::shared_ptr< Provider >	provider,
		std::vector< std::unique_ptr< Tool > >	tools,
		DeepResearchConfig	cfg = {}
	)

Build the Deep Research graph.

Expected channels on the initial RunConfig::input:

• user_query (string): the research question.

On completion, result.output["channels"]["final_report"] holds the markdown report.

Parameters

provider	LLM provider (SchemaProvider with the "claude" schema).
tools	Search/fetch tools made available to every researcher. Typical set: web_search, fetch_url.
cfg	Iteration budgets and model id.
