Prompt chaining
One giant prompt that reads an email, looks up the order, decides on a refund and writes a reply is hard to test and fails in mysterious ways. Four small steps, each with one job, fail in ways you can see and fix.
In this lesson you'll learn to
- Explain when splitting a task into a chain of prompts beats one large prompt, and what it costs.
- Use the common chain patterns, from sequential steps and parallel fan-out to review-and-revise.
- Pass results between steps as structured data, with checks in code in between.
- Estimate how errors compound along a chain, and design steps and gates to limit it.
