problem-definition

Produce a Problem Definition Pack in Markdown (in-chat; or as files if the user requests):

1) Context snapshot (product, user, trigger, decision, constraints) 2) Problem statement (1-liner + expanded) + why now 3) JTBD (primary job + key sub-jobs) + target segment notes 4) Current alternatives (including analog/non-digital) + gaps + switching costs 5) Evidence & assumptions log (what we know vs what we’re guessing)

6) Success criteria (outcome metric(s), leading indicators) + guardrails 7) Scope boundaries (in/out, non-goals, dependencies) 8) Prototype / learning plan (fast prototype + tests to de-risk) 9) Risks / Open questions / Next steps (always included)

定義產品問題並產生問題定義套件（問題陳述、JTBD、當前替代方案、證據和假設、成功指標、範圍邊界、原型/學習計劃）。在澄清問題空間時使用。 來源：liqiongyu/lenny_skills_plus。
