Idea: [what I want to make easier] Audience: [who will use it] One primary task: [task] Inputs and expected output: [details] Storage or sharing needed: [none, or explain] Constraints: [devices, accessibility, data boundaries, existing platform] Return: user story, smallest useful version, exclusions, screen flow, empty/error/success behavior, and three concrete acceptance examples. Identify any information you still need. Do not invent accounts, backend integrations or working payments. If a feature only works as a demonstration, label it clearly. Finish with a plain-language update and verification checklist. AI.Untangled | Personal educational example. Review and adapt before use.
