Abstract

The paper examines the engineering transition from static software paradigms to autonomous agentic architectures (Software Engineering 3.0). Instead of focusing on organizational theory, the analysis concentrates on the technical implementation of functional subject attributes in software agents: goal planning, causal reasoning, and standardized execution. Key architectural patterns for deploying distributed multi-agent systems (MAS) are synthesized, specifically focusing on the integration of generative models with Case-Based Reasoning for strictly typed decision reproducibility. The study details the technical requirements for Agent-to-Agent (A2A) communication protocols and the establishment of stable behavioral contracts between autonomous entities. Implementation challenges are addressed through the lens of data engineering, specifically context memory management and vector data integration within existing IT landscapes. Furthermore, the paper structures the technical aspects of Artificial Intelligence Trust, Risk, and Security Management (AI TRiSM), defining methods for behavioral control, immutable logging, and decision traceability in high-load environments. The efficiency analysis is reframed from general business ROI to specific engineering metrics, correlating system performance with the costs of development, integration, and computational maintenance.
