Turn a vague idea into a brief you can start with

Help me organize an idea that is not fully developed yet into a one-page mini brief. Idea: [自然语言描述]; intended audience: [谁会用]; my current resources and time: [限制].

First, list the facts you can confirm from the input and the assumptions that still need confirmation. Then write: the problem to solve, one specific use case, the minimum deliverable, three things explicitly out of scope, a way to validate whether it is useful, and the first step that can be started today. Do not automatically add accounts, payments, AI Agents, or a complex backend unless the input explicitly requires them. Finally, ask no more than three questions that would affect the direction. Keep the tone practical and stay within 500 characters.

请帮我把一个还不成熟的想法整理成一页小 Brief。想法：[自然语言描述]；面向的人：[谁会用]；我现在的资源和时间：[限制]。

先列出你从输入中确认的事实，以及仍需确认的假设。然后写：要解决的问题、一个具体使用场景、最小可交付结果、明确不做的三件事、验证是否有用的方法、今天可以开始的第一步。不要自动添加账号、支付、AI Agent 或复杂后台，除非输入明确需要。最后最多问三个会影响方向的问题。语气务实，500 字以内。
