Why big prompts fail

This lesson explains what a prompt framework is, why one giant prompt gives shallow answers, and how decomposition splits a job so each part gets full attention.

  • A prompt is the request you type into an AI tool such as ChatGPT, Claude or Gemini. A prompt framework is a reusable structure for that request, a short checklist of the parts a good prompt contains, usually named with an acronym so it is easy to remember.
  • Frameworks help because the AI fills in whatever you leave out with generic guesses. A framework makes sure you include the parts that change the answer, such as who it is for, what you want to achieve and the format you need.
  • Frameworks make prompts repeatable. You fill the same parts each time, save the prompt as a template and share it with colleagues, so the whole team gets consistent results.
  • Frameworks are not magic words. The value comes from the detail you put in each part. They help most when a request is complex or open to interpretation, while a quick, simple question can stay short.
  • There are well over sixty named frameworks, and most of them remix the same ingredients: role, task, context, audience, format, constraints and examples. Learning the ingredients matters more than memorising the names.
  • Decomposition is a prompting technique from AI research. Instead of slots to fill, it changes how the AI works through a task, and you can add it on top of any fill-in framework. The Prompt Report from 2024, the largest survey of prompting techniques, lists decomposition as one of six main families.
