PRD Author
SkillDocs & knowledgeUse this skill to author or expand a Product Requirements Document for a medical-data SaaS change. Drives PRD from business intent to a structured artifact that includes stage breakdown, measurable acceptance criteria, named dependencies, and a compliance section referencing COMPLIANCE_TAG.md. Handles iterative expansion: start lean, fill gaps surfaced by prd-implementation-precheck, until blockers/warnings are zero. Chinese trigger examples: "写 PRD", "PRD 起草", "补全 PRD", "PRD 分阶段", "PRD 完善", "需求文档撰写". Do NOT use for technical design (that's design.md / OpenSpec), do NOT bypass Step 0 (compliance precheck must come first). Success = PRD passes prd-implementation-precheck with zero blockers and zero warnings; stage breakdown present; compliance section linked.

Output structure (canonical PRD skeleton)
# PRD — <change name>
## 0. 元数据
- change_id, owner (PM), date, version
- 引用 COMPLIANCE_TAG.md 与数据等级
## 1. 背景与目标
- 业务问题(事实 + 痛点)
- 这次要解决什么、为什么现在
- 与既有产品/平台的关系
## 2. 用户与场景
- 主要用户角色 + 角色画像
- 核心场景 1-3 个
- 反例场景(这次不解决)
## 3. 功能范围
- In-scope(细到 feature 级)
- Out-of-scope(显式列出)
- Future scope(不在本 change 但未来要做)
## 4. 验收准则
- 业务侧 KPI(baseline + target + 测量方法)
- 用户侧验证(任务完成率、NPS 等)
- 技术侧(性能、可用性、合规通过率)
## 5. 阶段拆分
- Stage 1: 范围 + DoD + 退出准则
- Stage 2: 范围 + DoD + 退出准则
- Stage 3: ...
## 6. 依赖与协作
- 外部依赖(按团队 + 命名 owner + 截止日期)
- 内部依赖(哪些既有模块要改)
## 7. 风险与对冲
- Top 3 风险 + 对冲
## 8. 合规说明
- 链接 COMPLIANCE_TAG.md
- 数据等级
- 模型 allowlist 摘要
- PHI 流向描述
## 9. 关联文档
- TDD、design.md、相关 prototype
Workflow
- Anchor — 把用户的 business intent 转成第 1-2 章。
- Scope — 第 3 章是 PRD 的灵魂;显式列出 not-doing。
- Measurability — 第 4 章的每个 KPI 必须给"如何测"。
- Stage — 第 5 章按 "shippable stage" 拆分,不按 "month"。
- Compliance link — 第 8 章引用 Step 0 的 COMPLIANCE_TAG,不重复写。
- Iterate — 跑
prd-implementation-precheck→ 修 blocker/warning → 直到 0/0。
Common failure modes
- 抽象目标无 KPI:写"提升用户体验"而无指标。修:每个目标必须给"上线后我们看哪个数字"。
- No-out-of-scope:只写做什么不写不做什么。修:每个 in-scope 配一条 out-of-scope。
- Stage = 时间切片:错。Stage = 价值切片,每个 stage 上线即有用。
- 合规章节空填:写"遵守 HIPAA/PIPL" 而无具体引用。修:必须 link 到 COMPLIANCE_TAG.md 的具体条款。
