Define your goal
Start by clearly defining what you want the AI to do. Be specific: "Write a Python function" is better than "Write code." Include the expected output format.
Add context and constraints
Provide relevant background information, constraints, and requirements. Example: "The function should handle edge cases like empty input and invalid data. Use type hints."
Use a structured template
Structure your prompt with sections: Role (who the AI should act as), Task (what to do), Context (background), Format (how to respond), and Examples (few-shot learning).
Iterate and refine
Test your prompt with an AI model. If the output is not quite right, refine by adding more specific instructions, examples, or constraints. Good prompts often require several iterations.
