Frequently Asked Questions
What makes a good AI prompt?
A good prompt is specific (not vague), has clear output format requirements, provides relevant context, uses direct language (imperative verbs like 'Write', 'Analyze'), and includes constraints. Optionally, adding examples (few-shot prompting) significantly improves quality.
What is a system prompt?
A system prompt is an instruction given to an AI at the start of a conversation to set its role, behavior, and constraints. It's separate from the user message and typically used to configure the AI as a specialized assistant.
