About

A practical, code-first introduction to agentic systems for developers. You will learn the agent loop, tools and function calling, memory, planning, multi-agent patterns, guardrails, and evaluation, with honest coverage of what breaks in production. No hype and no videos: eleven focused chapters you can read in an evening or two.

You will learn to

  • ✓ Tell agents, chatbots, and workflows apart, and pick the least autonomy that solves the problem
  • ✓ Implement the core agent loop (perceive, plan, act, observe) in a few dozen lines of Python
  • ✓ Design tools and function-calling schemas that models use correctly, and turn errors into recoverable feedback
  • ✓ Choose the right memory strategy: transcript management, summaries, long-term stores, and retrieval
  • ✓ Apply planning, multi-agent patterns, guardrails, and human-in-the-loop controls with clear tradeoffs
  • ✓ Evaluate agents with small honest eval suites, pick a framework (or none), and scope an agent project that ships
