Rise of AI Agents: From Passive RAG to Autonomous Execution
Prerequisite: Familiarity with zero-trust data security and prompt boundary isolation covered in Part 5 — Enterprise Security & Data Poisoning. Answer-first: Passive RAG systems fail on ambiguous multi-step enterprise workflows because they cannot dynamically iterate, validate assumptions, or invoke transactional external systems. Autonomous AI agents powered by ReAct loops and the Model Context Protocol orchestrate distributed tool execution, dynamic replanning, and strict token budget guardrails to deliver reliable task automation without infinite loops. ...
