The Five-Part Prompt
Learn the basic architecture behind clear, reusable prompts.
Learning Objectives
- Identify the five prompt components that reduce ambiguity.
- Convert a vague instruction into a structured prompt.
- Add constraints that prevent unsupported guessing.
A prompt is a work brief
A useful prompt gives the model enough structure to complete a job without guessing what matters. Treat the prompt like a compact brief you would hand to a capable teammate.
The five core parts are role, context, task, format, and constraints. The role sets the lens. The context gives the source material. The task names the deliverable. The format tells the model how to shape the answer. The constraints define what the model should avoid.
The practical pattern
- Start with the role that matches the output.
- Add source material or the situation.
- State the exact action you want.
- Specify the answer format.
- Add boundaries such as evidence rules, length, or tone.
Use this structure when a prompt is part of a repeatable workflow: weekly summaries, account briefs, product synthesis, customer emails, or technical plans.
Examples
Before and after
Weak: Analyze these notes. Strong: You are a senior operations analyst. Use only the meeting notes to identify the top five blockers, evidence, owner, and next step.
Practice Exercise
Rewrite a vague work request
Take a real request from your team and rewrite it with role, context, task, format, and constraints.
- The prompt names the model role.
- The output format is explicit.
- The constraints say what evidence is allowed.
