Prompt Engineering for Engineers

Treat prompts as code. Learn the 6-part framework to get deterministic, production-grade results from LLMs.

If you are building software, you need a reliable data processor, not a chatbot. Most developers treat Prompt Engineering as a dark art - tweaking adjectives and hoping for the best. This is wrong. Prompt Engineering is like API design using natural language.

In this tutorial, we are going to kill the "vibes-based" approach and use a predefined template. We will take a vague, failing request and refactor it into an instruction set that returns a reliable JSON, every single time.

You are moving from "Can you please help me?" to function(context) -> output.

Tutorial Goals

  • Master the 6-Part Framework for writing production-ready prompts
  • Use delimiters to sandbox user input and prevent confusion
  • Implement Few-Shot Prompting to force adherence to specific formats
  • Use Chain of Thought (CoT) to force the model to think step-by-step
  • Learn the Anti-Patterns that cause hallucinations and bad output formatting
