Prompt Engineering

Craft prompts that get reliable, high-quality outputs

🔑 Key Concepts

Clarity — Be specific. 'Summarise this in 3 bullet points' > 'Summarise this'. Explicit instructions reduce ambiguity.
Few-shot examples — Show the model what you want with 2-3 examples. Output quality jumps dramatically with examples.
Chain-of-thought — Add 'Think step by step' or break complex tasks into sequential prompts. Reduces errors on reasoning tasks.
Temperature — 0 = deterministic (code, data extraction). 0.7 = creative (writing, brainstorming). Match temperature to task.

💡 Practice: Try implementing each concept yourself before moving on. Reading about RAG and building RAG are very different things.
