LLM-Powered Autonomous Agents: Comprehensive System Design & Architecture Analysis
Landmark reference architecture decomposing autonomous agents into planning (subgoal decomposition, reflection), memory (short-term in-context, long-term vector search), and tool execution loops.
Identifies fundamental limits of finite context windows, reliability bottlenecks in long-term planning, and unreliability of open-ended natural language tool interfaces.
Context: Large language models, vector memory systems, ReAct prompting, and agent loops.
