discover

<!-- workflow-deps:start --> ## 安装依赖预检（执行工作流之前） 本工作流入口 **discover** 只负责编排；单独安装它**不会**自动安装所调用的技能。 必需技能：`pm-market`、`pm-competitor`、`pm-demand`、`pm-priority`。 新产品额外需要 `pm-brainstorm`；仅在已有相关头脑风暴产物或用户明确跳过时可不调用它。 先用当前平台的技能列表检查必需技能是否可用。**若缺少依赖，停止工作流**，不要假装已执行；告知用户缺少的技能并给出安装方式。不要擅自安装或跳过。 完整安装命令（只装本入口并不够）： ```bash npx skills add https://github.com/konglong87/superPM --skill discover pm-market pm-competitor pm-demand pm-priority pm-brainstorm ``` 没有 Node.js/npm 时，可按仓库 README 手动安装完整技能包；安装后重新检查技能列表，再继续流程。 <!-- workflow-deps:end --> ## Workflow contract When the full pack is installed, also consult `skills/_shared/workflow-contract.md`; standalone installation follows the complete steps below. For a new product idea, run `/pm-brainstorm` before this chain unless a relevant artifact exists or the user explicitly opted out.

Reuse relevant artifacts after confirmation; report only outputs actually created. ## Overview This command chains 4 skills into a complete product discovery workflow: 1. **pm-market** — Market landscape & sizing 2. **pm-competitor** — Competitive analysis 3. **pm-demand** — Demand validation & pain point analysis 4. **pm-priority** — Prioritization & opportunity ranking Each step pauses for user confirmation before proceeding. ## Execution Flow ### Step 1: Market Analysis Run the market analysis skill to understand the market landscape. ...
