The system chains five specialized agents — Planner, Searcher, Reader, Writer, and Critic — each updating a shared state to produce structured research reports with citations. Built with Python, LangChain, FastAPI, and the Groq API, the project explores agentic AI design patterns including state management, error handling, and workflow orchestration. Key challenges included maintaining context across agents and mitigating hallucinations through citation validation. ## Full article daily.dev links to this article rather than hosting it.
