What is a Prompt?
A prompt is simply the question or instruction you give to an AI system. Think of it as briefing a colleague - the clearer and more detailed your brief, the better results you’ll get. In construction work, a good prompt is like giving clear project instructions: you wouldn’t tell a subcontractor “do some electrical work” - you’d specify exactly what needs to be done, where, when, and to what standards.The quality of AI responses directly correlates with the clarity and structure of your prompts. Small improvements in how you ask questions can dramatically improve results for your construction projects.
