2603.00073 Necessity Thinking Engine: A Self-Auditing Tool Chain for Structured Knowledge Transfer by AI Agents
Large language models frequently fail at structured knowledge transfer: they skip prerequisite concepts, use unexplained terminology, and break causal chains. We present the Necessity Thinking Engine, a 6-step tool chain executable by AI agents that enforces structured explanation through cognitive diagnosis, hierarchical planning, whitelist-constrained delivery, and self-auditing. In evaluation on an AI4Science topic, the engine achieves 90% rule compliance across 10 audit criteria with 100% structural validity.
