Overcoming Simple Prompt Limits: A Guide to Designing LLM-Based Autonomous Agent Workflows (ReAct Pattern)
Simple prompts alone cannot automate complex work. This guide shows how to design the full architecture of an AI agent workflow that repeatedly plans, uses tools, and validates results with LLMs, step by step using the ReAct pattern.
Ensuring AI Agent Reliability: From Hallucination Prevention to Exception Handling — A Practical Python Code Guide
Reliability is the hardest part of putting AI agents into production. This guide goes beyond simple prompt instructions and presents the core code developers must implement themselves: external validation logic (guardrails), conversation st
