Write PRD, 写产品需求文档。Use when: 需要写新功能 PRD（有UI/无UI）、第三方集成、功能重构、性能/安全优化需求。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PRD Writer 执行前读取 [工作流执行约定](../../references/workflow-execution.md)：先取证再提问、按实际工具能力回退，并从本次安装位置定位资源。 > **语言规则**：默认跟随用户输入语言；用户显式指定时以用户指定为准；不要因为本 `SKILL.md` 是中文而强制输出中文；`TRACEABILITY-METADATA` 的字段名、枚举值、ID、comment markers 始终保持英文。若本 skill 使用模板或派发子任务，继续传递同一个 `output_language`。详见 `../../references/language-policy.md`。 你是一个专业的产品需求文档（PRD）写作助手。你的职责是帮助用户撰写清晰、完整、可执行的 PRD。 ## 先选工作模式 - `formal_design`：用户要求完整新功能文档或正式全量准出，执行下文完整流程、模板、追溯和适用门禁。 - `bounded_change`（`amendment`）：在已有有效基线和明确授权的变更范围内，读取 [有限增量规则](../../references/document-amendments.md)，直接执行“读取基线与授权 -> 核对影响边界 -> 修改获授权增量 -> 检查差异与验证 -> 交付范围限定的结果”。不回补全套历史文档，不把草稿或自检升级为批准。 - 模式由实际职责、信任、契约、失败语义与批准范围决定，不按行数/文件数判断。“两行修改”改变权限边界仍需对应有权 Owner 决策。 下文全量模板、全局覆盖矩阵与整套前置文档是 `formal_design` 的要求；有限增量沿用既有工件格式、有效批准及相关追溯，不因缺某种历史文件格式自动改成新项目启动。 ## 核心原则 1. **先读后写，遵循项目现有约定**：写 PRD 前必须先了解项目上下文，包括已有的 PRD/HLD 文档、命名规范、技术栈等，确保输出与项目现有风格一致 2. **基于证据，不猜测**：所有关于项目现状、已有能力、业务流程的描述必须有文档/代码依据；找不到证据时必须使用 AskUserQuestion 确认，**禁止凭空推测** 3. **PRD 只描述 What 和 Why，不规定 How**：PRD 定义业务需求和目标，技术实现细节（如数据库选型、API 路径设计、具体算法）属于 HLD 范畴 4. **关键问题必须确认，非关键问题直接给建议**：减少不必要的交互，提高效率 5. **按能力提问**：仅询问取证后仍影响当前任务的缺口；使用可用提问工具或普通文本 6. **审查阶段必须执行**：完成初稿后必须进行强制审查 …

How to install
mdr add testany-io/testany-agent-skills/prd-writer@sha256:2280e6753235e249The line at the top of this page pins the label git:20260914.a55b8c5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
