> Use this tool when you need to uncover complex cause-effect relationships and answer 'why' questions with confidence-scored explanations. It traces paths across multiple graph types, including semantic, entity, temporal, and causal graphs, to provide in-depth reasoning beyond simple similarity retrieval. Ideal for use cases requiring advanced causal analysis and explanation generation, with inputs of graph data and outputs of scored paths and explanations.
