Prompt Patterns

Problem

AI prompts that work in testing break in production. Small changes in wording cause wildly different outputs. There's no systematic approach—just trial and error.

Solution

A library of proven patterns that consistently produce better results.

• Chain of Thought: "Think step by step..."
• Few-Shot: Show examples to guide format
• Role-Based: "You are an expert..."
• Structured Output: Force consistent JSON
• Self-Consistency: Multiple answers, majority vote

Demo

Take a simple task like "summarize this text." Compare a naive prompt vs a structured prompt with chain-of-thought. See the dramatic improvement in quality and consistency.
