Agent-as-a-Tool: A New Era of AI Orchestration

Abstract As Large Language Model (LLM) agents increasingly integrate numerous external systems, they suffer from Tool Space Interference (TSI), a phenomenon causing context bloat, attention dilution, and degraded reasoning accuracy. In this paper, we introduce the Agent-as-a-Tool paradigm—an evolutionary, practical implementation of the recently proposed Self-Optimizing Tool Caching Network (SOTCN) and Federated Context-Aware Routing Architecture (Federated CARA). By leveraging Retrieval-Augment
