Principles of Writing Effective Prompts

What is a Prompt?

A prompt is the information or instructions you give an AI assistant. The quality of your prompt often determines the quality of the response.

The Four Elements of an Effective Prompt

Persona

Who you are or who you want Gemini to act as.

Task

The specific action you want Gemini to perform.

Context

Background information that helps Gemini understand the situation and your goals.

Format

How you want the response presented (e.g., bullet points, table, email, report, presentation outline).

The PTCF Framework

A simple way to improve prompts is to include:

• Persona;
• Task;
• Context;
• Format.

The more relevant information you provide in these areas, the more tailored and useful Gemini's responses are likely to be.

Using Roles and Personas

You can ask Gemini to adopt a specific role, such as:

• Tutor;
• Coach;
• Travel guide;
• Chef;
• Marketing consultant;
• Project manager;

This helps Gemini tailor its tone, expertise, and recommendations to the situation.

Iterate
