🧠 ai-agent-handbook - Learn How AI Agents Work

📘 What this is

ai-agent-handbook is a clear guide to how AI agents work under the hood. It helps you understand the parts that make agent systems run, such as memory, tools, prompts, loops, and multi-agent setup.

This guide is made for people who want to learn how agent frameworks work without getting lost in hard language. It uses simple examples and plain steps so you can follow along even if you are new to this topic.

🛠️ Main topics covered

🤖 Agent loops

Learn how an agent thinks step by step, makes a choice, takes action, and checks results.

🧠 Memory systems

See how short-term and long-term memory work in agent apps, including episodic memory and saved context.

🧩 Context management

Understand context rot, compaction, and how systems keep the right data in view.

📝 System prompt assembly

Learn how the final prompt gets built from rules, task data, and user input.

🔌 Tools and MCP

See how agents use tools, why tool sprawl happens, and how MCP helps connect systems in a cleaner way.

👥 Multi-agent orchestration

Learn how several agents can work together with Plan/Act patterns and shared tasks.

📄 Progressive disclosure

See how to give an agent only the detail it needs at each step.

🧰 Framework comparison

Compare more than 30 frameworks and learn what each one does well.
