OPENAI'S PRACTICAL GUIDE TO BUILDING AGENT

Summary from the TLDR AI newsletter

This guide emphasizes starting with single agents before multi-agent systems, using manager patterns where one agent coordinates others via tool calls or decentralized handoffs for peer-to-peer task delegation. Key insights include implementing guardrails as layered defenses (LLM-based classifiers, regex filters, and moderation APIs), designing tools for messy long-horizon tasks, and building human-in-the-loop mechanisms triggered by failure thresholds or high-risk actions.
