# hypotree

> hypotree — tygryso-hypotree. Use this tool when you need to manage complex hypotheses and revise beliefs based on evidence, enabling agents to structure knowledge as a directed acyclic graph with automatic updates and pruning. It solves problems of knowledge management, belief revision, and hypothesis testing in agentic R&D. The hypotree tool takes in hypotheses and evidence as inputs and outputs a revised graph of working knowledge, ideal for use in research and development contexts where knowledge is constantly evolving.
