Agent architecture
Agent state machines
Represent agent progress as explicit states and transitions.
Lesson overview
Agent state machines
Model-driven loops become easier to reason about when states are explicit.
Typical states include received, planning, awaiting_tool, executing, awaiting_approval, evaluating, completed, and failed.
Persist state for long-running work so a process restart does not lose the workflow.

Step 1
Theory
Agent state machines
Model-driven loops become easier to reason about when states are explicit.
Typical states include received, planning, awaiting_tool, executing, awaiting_approval, evaluating, completed, and failed.
Persist state for long-running work so a process restart does not lose the workflow.
Step 2
Example
Example
Apply Agent state machines to a realistic production scenario and trace the decision step by step.
Step 3
Code
Code
Add implementation notes or a runnable example for this concept.
Step 4
Practice
Practice
Write down the inputs, expected output, constraints, and one failure case for Agent state machines.
Step 5
Quiz
Quiz coming soon.
Step 6
Challenge
Challenge
Design a production-ready solution for Agent state machines and explain one important trade-off.
