Why Well-Written Prompts Are Almost Always Structured
Structured prompts with clear formatting, sections, and explicit instructions produce better AI responses than unstructured ones by reducing ambiguity and guiding reasoning.
Background
Large language models (LLMs) like ChatGPT and Claude process prompts — the text instructions a user types in. Well-crafted prompts produce dramatically better outputs, and the emerging best practice is "structured prompting": using clear sections, delimiters (e.g., --- or ###), bullet points, and formatting to separate instructions from context, constraints, and desired output format.
