Knowledge-extractor: a self-evolving scientific framework for hydrogen energy research driven by AI agents

Figure 3. The Cyclic Workflow of the DeepResearchAgent. The agent operates in a core iterative loop comprising three stages: (A) Plan, where the user query is decomposed into actionable steps; (B) Execute, where information is gathered using automated tools; (C) Assess & Reflect, where the collected evidence is evaluated. This loop continues, refining the plan with each iteration, until the Termination Criteria are met. Upon completion, the agent proceeds to the (D) Final Step: Synthesize, where all verified findings are integrated into a comprehensive, citable report.
