Week 2 — Agentic Systems

Prerequisite: Week 1

Week 2 moves from using agentic tools to building agentic systems of your own. The goal: by the end of the week you will have built and launched a working agentic workflow — from a first REACT loop to a monitored production system that automates real work.

Objectives

By the end of the week you should be able to:

• Explain the anatomy of an agentic system and build a REACT loop.
• Build a simple harness around an agent.
• Build good, reliable, reusable skills.
• Build an agentic workflow system with human-in-the-loop control, observability, guardrails, cost awareness, and memory.

The week at a glance

• Days 1–2: intro to agentic systems — building a REACT loop and a simple harness.
• Day 3: Monitoring, telemetry, and observability.
• Days 4–5: building an agentic workflow system — human in the loop, guardrails, costs, autonomous and semi-autonomous operation, and memory.

The Week's core:

Iterative self improvement. All the tools, techniques, and strategies we cover this week are designed to help you use the systems to improve themselves.
