What Is RAG and Why Every AI App Uses It
The simple trick that lets AI answer questions about your own stuff — explained in plain language.
Prompt engineering is the practice of designing and refining inputs to AI models to get more accurate, useful, and consistent outputs. As language models become more capable, knowing how to communicate with them effectively is a high-leverage skill — whether you're a developer, product manager, or anyone building AI-powered workflows. This collection covers the core techniques: chain-of-thought prompting, few-shot examples, system prompts, role-based prompting, output formatting, and how to avoid common failure modes. Small changes in how you phrase a prompt can dramatically change the quality of the results, and these lessons show you exactly how and why.
