Prompt with Purpose
Turn a vague request into a task an AI system can execute and you can evaluate.
Core concept
By the end
You will be able to
- Write prompts with a goal, context, constraints, and output contract.
- Separate trusted instructions from untrusted input.
- Define a useful stopping condition.
01
A prompt is a working contract
Strong prompts say what outcome is needed, why it matters, what information is trustworthy, what boundaries apply, and what a successful response looks like.
The model should not have to guess the audience, format, source of truth, or definition of done.

Goal: [OUTCOME]
Context: [TRUSTED FACTS]
Constraints: [BOUNDARIES]
Deliverable: [FORMAT]
Verify: [CHECKS]02
Inspect, correct, and reuse
Prompting is iterative. Inspect the result, identify the missing constraint or context, and improve the reusable instruction instead of repeatedly requesting a vague improvement.
