Lesson
Prompt chains turn one risky giant prompt into a sequence of smaller decisions. Each step has a clear input, output, and quality check.
Chains are easier to debug because you can see where the system misunderstood, hallucinated, or lost important context.
Objectives
Split a task into stages.
Pass structured outputs between stages.
Find where a chain can fail.
Practice
Map a research-to-summary workflow into three model calls.
Define the output schema for each step.
Next action
Design a three-step chain for summarizing meeting notes.
