把模糊想法变成可验收需求

把输入想法拆成目标用户、具体场景、要完成的任务、输入输出和验收条件。列出已知事实、合理假设与待确认问题。只问会改变实现的问题，最多五个，并给出可选答案。最后提供一个最小可交付版本和明确不包含的范围。

输入材料：
{{context}}

目标与约束：
{{constraints}}

只依据输入回答。缺少关键信息时明确标记未知，必要时先提问。输出应可直接用于当前任务。

Turn the idea into a target user, concrete scenario, job, inputs, outputs and acceptance criteria. Separate facts, assumptions and open questions. Ask at most five questions that could change implementation, with possible answers. Finish with a minimal deliverable and explicit scope boundaries.
