Prompt Engineering

Learn to write prompts that get reliable answers from AI models. Fourteen short chapters, each with a real before and after, show how to be specific, add context and roles, control the format, use examples, reason step by step, resist prompt injection, ground answers and test your prompts like code.

Who it is for

Students, developers and professionals who use AI chat tools or APIs and want consistent, useful answers instead of trial and error.

What you will be able to do

• Rewrite a vague prompt into a specific one that can be checked
• Use context, roles, examples and output formats on purpose
• Get JSON or tables a program can read
• Reduce made-up answers and pasted-text injection
• Build reusable prompt templates and system prompts
• Test two prompt versions on the same inputs and keep the better one
