Lesson: The Art of Structured ChatGPT Prompting
Welcome to our lesson on Structured Prompt Engineering. To get the most accurate, relevant, and high-quality outputs from large language models like ChatGPT, you need to move beyond simple questions and adopt a structured approach.
Our goal is to learn the simple, yet powerful, four-part formula for creating effective prompts.
The Core Prompting Formula
The most effective prompts follow a structure that clearly defines the AI's boundaries, tasks, and output requirements. Think of it as giving ChatGPT a job description, a task list, and a required deliverable format.
The formula is:
ROLE + TASK/NEEDS + DETAILS/CONSTRAINTS + FORMAT
Formula Components Explained:
* (ROLE): Define the persona or expertise. This tells the AI who it is and sets the context for its knowledge base and tone.
* (NEEDS) and (TASK): Define the goal and the steps to achieve it. This tells the AI what the final output should be and how to process the request.
* (Details) and [DO NOT...]: Define the constraints. This refines the process by adding specific instructions, style guides, or rules the AI must follow (or avoid).
* (FORMAT): Define the structure of the output. This ensures you receive the result in a usable way (e.g., a bulleted list, a table, or specific code).
1. Defining the (ROLE)
Adopting a role is the fastest way to improve output quality because it instantly activates a specific knowledge domain.
Examples:
Expert Accountant
,Competent Marketing Manager ,
,Skilled Doctor
,Agile Scrum Master
,Blockchain Developer
2. Defining the (TASK) and (NEEDS)
This is the action-oriented part of your prompt. You tell the AI what you need and what specific actions to take.
| Core Task Verbs (What to do) | Example (NEEDS) |
|---|---|
| Generate | Generate an email sequence for a product launch. |
| Translate | Translate the terms and conditions into French. |
| Optimize | Optimize the landing page copy for mobile conversion. |
| Summarize | Summarize the key findings from the annual report. |
| Validate | Validate the syntax of the provided Python script. |
3. Applying (DETAILS) and [DO NOT...]
These are your process modifiers—the rules that shape the tone, style, and content.
| (Details) - Things to do | [DO NOT...] - Constraints to follow |
|---|---|
| Use clear, concise language. | DO NOT use corporate jargon. |
| Focus on a positive, encouraging tone. | DO NOT exceed a word count of 500 words. |
| Structure the argument chronologically. | DO NOT include any external links. |
| Include a strong call-to-action (CTA). | DO NOT assume any prior knowledge of the topic. |
4. Specifying the (FORMAT)
The format is how you want the data delivered. This is crucial for using the output directly in another application or platform.
| Text/Code Formats | Data Formats | Presentation Formats |
|---|---|---|
| Plain text | JSON, XML, CSV | Excel, PowerPoint, PDF |
| HTML, Markdown | SQL, JavaScript | LaTeX |
| CSS, PHP, Python | YAML | SVG |
The Formula in Action: A Complete Example
Let's combine all the elements to create a powerful prompt:
Prompt:
> "Act like an Accomplished Sales Representative. I need a persuasive pitch deck script for our new SaaS product, you will research the pain points of small businesses in the e-commerce sector and incorporate competitive differentiators, in the process, you should focus on solving a single, major problem clearly and passionately, please [DO NOT use industry acronyms without defining them], input the final result in a Markdown outline format with H2 headings for each slide."
Your Turn: Try to write a prompt using the formula above to have ChatGPT write a resume for you!
