What is Prompt Engineering?

Prompt engineering improves output quality by turning vague requests into testable, constrained instructions.

This starter module focuses on a simple but practical workflow so learners can build intuition before advanced topics.

How Prompt Iteration Works

1

Specify

Clearly define task intent, audience, and expected output shape.

2

Constrain

Add strict formatting and quality rules to reduce ambiguity.

3

Validate

Test edge cases and revise the prompt until failure modes drop.

Real World Example

Prompt quality through iteration.

Email Summarization Workflow

A team builds a prompt for summarizing long email threads into action items.

1

Objective

Summarize into bullets with owners and due dates.

2

Constraints

Max six bullets, neutral tone, and no invented details.

3

Validation

Run noisy and missing-context test cases before production.
