Clarifying Question Generation

via “human-in-the-loop clarification prompting for ambiguous queries”

A modular Agentic RAG built with LangGraph — learn Retrieval-Augmented Generation Agents in minutes.

Unique: Embeds clarification as a first-class agent node in the LangGraph workflow, triggered by conditional routing, rather than implementing it as a pre-processing step or external validation layer. The clarified context is merged back into the conversation state, enabling the agent to learn from the clarification in subsequent reasoning steps.

vs others: More user-friendly than silent retrieval failures and more efficient than always retrieving multiple interpretations; clarification is integrated into the agent loop rather than bolted on as a separate validation step.
