决策纪律(全文只在此声明一次,各步骤直接引用):影响目标范围、业务规则、权限/安全边界、API 契约、数据模型、迁移/兼容性、验收标准、显著成本、风险接受或测试策略的缺口,按 Decision Exposure Gate 分类。needs_user_answer 先按 Topic 查决策账本,仍未解决时用 AskUserQuestion 提问,回答前不得把问题写成风险、待确认事项或假设后继续生成;用户回答后先更新账本,再更新对应产物。
仅在以下场景使用:
/t-design [方案名称]不要因为用户只是问"怎么实现""大概怎么做"就自动触发本 skill。
基于用户故事、PRD 草稿、已发布 PRD 基线、技术预研、用户已准备的仓库内资料和现有代码,生成可实施、可追踪、可用于 /t-task 的技术设计。/t-prd-check 是推荐的可选上游检查;未运行时,本 skill 必须自行完成关键需求来源混合验证。
设计拆分为一份主文档加按端拆分的分端设计文档;每个适用端由对应设计 subagent 生成,主会话负责编排、跨端裁决和汇总。不适用端不创建分端文档,只在主文档 §4.2 标记"不适用"及原因。
如果未传方案名称,立即终止并提示:

D2 工程取舍由设计阶段明确选择并写入 Design;符合 Decision Continuity Contract 的 Entry Gate 时才回写决策账本。
只搜索真实目录:
docs/user-stories/**/*.md.ai/user-stories/**/*.md.ai/prd/**/*.mddocs/prd/**/*.md.ai/tech-research/**/*.mddocs/design/**/*.md、.ai/design/**/*.md(如果存在相关先例)优先做法:先从索引定位候选文档,再对候选文档做 Grep,最后 Read 真正相关的少量文件。
业务功能设计至少提取:用户故事 ID/标题/优先级/来源文件、场景概述或验收目标摘要、PRD 草稿中的当前候选业务边界/规则/非功能要求、已发布 PRD 基线及草稿相对基线的差异、draft 用户故事相对已发布故事的新增或变更场景、Decision Log 中影响设计的 Active Decisions / 已解决问题 / 本阶段到期的 Deferred Questions。草稿与正式来源的并存裁决按需求来源边界协议执行;冲突无法确认覆盖关系时停止并提示修正草稿,必要时运行 /t-prd-check [feature]。
如果没有找到足够的用户故事或 PRD:
.ai/tech-research/$ARGUMENTS.md;存在且足以支撑纯技术方案时继续生成,并在需求来源中标记 PRD/用户故事不适用分析真实代码结构,不要假设,输出:现有实现入口(后端、前端、Flutter 各自的现状)、可复用模块、需要修改的边界、与当前架构或约束冲突的点。代码分析复杂时用 Task 启动 Explore agent,要求返回现有实现位置、可复用点、受影响模块和具体文件路径。
${CLAUDE_PLUGIN_ROOT}/protocols/task-phase-execution.md 的 phase 结构、现有代码结构(如 frontend/、Flutter 工程是否存在)和 Decision Log。判定结果影响拆分方向且无法确定时,使用 AskUserQuestion 确认按适用端调度设计 agent,subagent_type 映射:
| 端 | subagent_type | 模板 | 输出 |
|---|---|---|---|
| backend | backend-design | template-backend.md | .ai/design/$ARGUMENTS/backend.md |
| frontend | frontend-design | template-frontend.md | .ai/design/$ARGUMENTS/frontend.md |
| flutter | flutter-design | template-flutter.md | .ai/design/$ARGUMENTS/flutter.md |
调度顺序:backend 适用 → 先调度 backend-design,成功后再调度 frontend-design / flutter-design;backend 不适用 → 可并行调度。同批次同角色复用按 ${CLAUDE_PLUGIN_ROOT}/protocols/subagent-dispatch.md 执行。
每次调度前必须:

命中项按 Decision Exposure Gate 分类处理;重新扫描通过前不得交付设计。随后运行 python ${CLAUDE_PLUGIN_ROOT}/scripts/check-design.py ".ai/design/$ARGUMENTS.md" 做确定性结构校验(章节、模板占位符、适用端文档、契约 operation、文件影响汇总和路径操作)。两项扫描全部通过后,才把 .state.json 写为 complete。
高风险、跨端或长文档设计在完成前额外调度一个无原会话背景的通用只读 agent,只提供全部设计文档和以下问题:实现入口、契约唯一来源、失败/权限/兼容路径、测试入口、文件影响范围。若读者无法从文档稳定回答或发现矛盾,修正文档并重新执行两项扫描;简单设计跳过时在收尾说明。
逐项按对应 agents/*-design.md 的"着重点"和质量清单验收。额外拒绝:

## 适用范围
仅在以下场景使用:
- 用户明确要求"技术设计""方案设计""架构设计""API 设计""数据模型设计"
- 用户明确执行 `/t-design [方案名称]`
- 已经确认这是新功能或较大能力扩展,需要正式设计文档进入 DDD 流程
不要因为用户只是问"怎么实现""大概怎么做"就自动触发本 skill。
## 目标
基于用户故事、PRD 草稿、已发布 PRD 基线、技术预研、用户已准备的仓库内资料和现有代码,生成可实施、可追踪、可用于 `/t-task` 的技术设计。`/t-prd-check` 是推荐的可选上游检查;未运行时,本 skill 必须自行完成关键需求来源混合验证。

## Input Contract
上游输入(按设计类型选择;读取顺序:先索引,再 `.ai/decision` / `.ai/decision-log`,再需求来源,最后 guides):
- 业务功能设计:

- `docs/prd/00-index.md`、`docs/user-stories/00-index.md` — 索引
- 纯技术方案设计:
- `.ai/tech-research/<feature>.md` — 技术预研报告,可作为唯一上游需求来源
- 仅适用于不涉及业务逻辑、产品规则、用户可见流程或验收目标变动的设计
可选输入:
- `${CLAUDE_PLUGIN_ROOT}/guides/core/environment-and-testing-guide.md` — 环境与测试指南
- `${CLAUDE_PLUGIN_ROOT}/guides/backend/development.md` — 后端开发规范
- `${CLAUDE_PLUGIN_ROOT}/guides/frontend/development.md` — 前端开发规范
- `${CLAUDE_PLUGIN_ROOT}/guides/flutter/development.md` — Flutter 开发规范(目标项目启用 Flutter 时)
- `${CLAUDE_PLUGIN_ROOT}/guides/flutter/demo-testing.md` — Android Patrol 用户故事演示规范(设计要求 Flutter Demo 时)
- `${CLAUDE_PLUGIN_ROOT}/guides/core/quality.md` — 质量规范
## Output Contract
下游产出:
- `.ai/design/$ARGUMENTS.md` — 设计主文档,包含:
- 目标与范围
- 用户故事/PRD/技术预研引用与完整 Decision Trace
- 跨端现状概览
- 总体设计与关键取舍、交付端范围
- 跨端契约(API 契约摘要与契约源声明)
- 分端设计摘要
- 测试与验收策略(跨端汇总)
- 风险与验证动作(汇总)
- 文件影响范围(全量汇总,`/t-task` 的唯一拆分依据)
- `.ai/design/$ARGUMENTS/backend.md` — 后端分端设计(适用时),包含 API 契约(唯一设计源)、数据库设计、领域逻辑、权限安全、详细设计、后端测试策略
- `.ai/design/$ARGUMENTS/frontend.md` — 前端分端设计(适用时),包含页面/组件/线框、状态与数据流、交互与关键状态、性能、测试与 Demo 策略

- `.ai/design/$ARGUMENTS/.state.json` — 设计生成状态;结构见 `${CLAUDE_PLUGIN_ROOT}/protocols/design-state-contract.md`,只有 `complete` 可被下游消费
- `.ai/decision-log/$ARGUMENTS.md` — 复用上游决策;仅在产生用户决策、问题状态变化或重要 AI 决策时更新
## 核心约束
- 若存在 `.ai/decision/<feature>.md`,设计必须尊重其中目标用户、Scope Direction、D0/D1 产品决策和 Handoff;不得用技术方案静默改变立项结论
- 若存在 `.ai/decision-log/<feature>.md`,必须逐项承接影响设计的 Active Decision;不得重复询问 Resolved Question,也不得使用 Superseded Decision
- 纯技术方案没有 PRD/用户故事时,以 `.ai/tech-research/<feature>.md` 中的技术目标、约束和影响范围为准;必须在主文档中声明"纯技术方案设计,不涉及业务逻辑变动",并引用对应技术预研报告;执行流程与质量门禁以 `${CLAUDE_PLUGIN_ROOT}/guides/` 为准
- 只引用用户故事,不粘贴完整故事正文或整段 Gherkin
- 优先复用现有实现,不凭空设计新架构
- 默认不搜索额外资料;人类在进入 `/t-design` 前应已准备好相关资料。只有在人类明确要求补充外部依据时,才可将外部资料作为附加参考
- API 契约的单一设计源是 backend 分端文档;frontend/flutter 分端文档只声明依赖的接口与字段,不得复制或另立契约;后端不适用时以现有 OpenAPI/SDK 或接口为契约源
- 主文档不承载 API 字段表、数据库表结构和页面线框等分端细节;细节只活在对应分端文档,主文档保留摘要与链接
- 数据库设计遵循"尽量简洁、当前必需、避免过度审计设计"
- 现状依据及 MODIFY/DELETE 路径必须真实存在;CREATE 路径可以尚不存在,但父目录必须真实存在,并给出相邻实现或项目规范作为命名依据
- 分端文档由对应设计 subagent 生成;主会话不得绕过 subagent 代写分端设计,除非该端不适用
## 工作流程
### 1. 验证参数和输出位置
- 校验 `$ARGUMENTS` 非空;文件名仅允许中文、英文、数字、空格、下划线、连字符
- 如果 `.ai/design/$ARGUMENTS.md` 或 `.ai/design/$ARGUMENTS/` 下任一分端文档已存在,先询问是否覆盖。用户确认后先重新判定适用端,删除上一轮存在但本轮不适用的分端文档,再按输出协议写入 `in_progress` 状态
### 2. 收集最小必要输入
如果当前上下文不足,使用 `AskUserQuestion` 只补齐以下内容;用户已在对话或参数里给出的信息不重复提问。提问遵循决策纪律(先查账本):
- 功能目标或问题陈述
- 人类已准备好的相关资料路径或名称
- 需要覆盖的范围边界
- 交付端范围(仅当无法从需求来源、现有代码或 Decision Log 判断时)
D2 工程取舍由设计阶段明确选择并写入 Design;符合 Decision Continuity Contract 的 Entry Gate 时才回写决策账本。
### 3. 搜索需求来源
只搜索真实目录:
- `docs/user-stories/**/*.md`
- `.ai/user-stories/**/*.md`
- `.ai/prd/**/*.md`
- `docs/prd/**/*.md`
- `.ai/tech-research/**/*.md`
- `docs/design/**/*.md`、`.ai/design/**/*.md`(如果存在相关先例)
优先做法:先从索引定位候选文档,再对候选文档做 `Grep`,最后 `Read` 真正相关的少量文件。
业务功能设计至少提取:用户故事 ID/标题/优先级/来源文件、场景概述或验收目标摘要、PRD 草稿中的当前候选业务边界/规则/非功能要求、已发布 PRD 基线及草稿相对基线的差异、draft 用户故事相对已发布故事的新增或变更场景、Decision Log 中影响设计的 Active Decisions / 已解决问题 / 本阶段到期的 Deferred Questions。草稿与正式来源的并存裁决按需求来源边界协议执行;冲突无法确认覆盖关系时停止并提示修正草稿,必要时运行 `/t-prd-check [feature]`。
如果没有找到足够的用户故事或 PRD:
- 优先检查 `.ai/tech-research/$ARGUMENTS.md`;存在且足以支撑纯技术方案时继续生成,并在需求来源中标记 PRD/用户故事不适用
- 不存在或技术预研不足、且缺失影响方案判断时,按决策纪律要求用户补齐目标、范围或来源后再继续
- 纯技术方案设计至少提取:技术目标、当前约束、选定技术路线、依赖或版本变化、影响范围、风险和不涉及业务逻辑变动的边界声明
### 4. 分析现有实现
分析真实代码结构,不要假设,输出:现有实现入口(后端、前端、Flutter 各自的现状)、可复用模块、需要修改的边界、与当前架构或约束冲突的点。代码分析复杂时用 `Task` 启动 Explore agent,要求返回现有实现位置、可复用点、受影响模块和具体文件路径。
### 5. 确定交付端范围与契约归属
- 判定 backend / frontend / flutter 哪些端适用:依据需求来源中的交付端描述、`${CLAUDE_PLUGIN_ROOT}/protocols/task-phase-execution.md` 的 phase 结构、现有代码结构(如 `frontend/`、Flutter 工程是否存在)和 Decision Log。判定结果影响拆分方向且无法确定时,使用 `AskUserQuestion` 确认
- 契约归属:backend 适用时,API 契约由 backend 分端设计产出,backend 设计必须先行;backend 不适用时,契约源为现有实现分析中确认的现有接口/OpenAPI/SDK,frontend/flutter 可直接并行生成
- 在主文档 §4.2 记录交付端范围和判定依据
### 6. 分端生成设计(subagent 编排)
按适用端调度设计 agent,`subagent_type` 映射:
| 端 | subagent_type | 模板 | 输出 |
|---|---|---|---|
| backend | backend-design | [template-backend.md](${CLAUDE_PLUGIN_ROOT}/skills/t-design/template-backend.md) | `.ai/design/$ARGUMENTS/backend.md` |
| frontend | frontend-design | [template-frontend.md](${CLAUDE_PLUGIN_ROOT}/skills/t-design/template-frontend.md) | `.ai/design/$ARGUMENTS/frontend.md` |
| flutter | flutter-design | [template-flutter.md](${CLAUDE_PLUGIN_ROOT}/skills/t-design/template-flutter.md) | `.ai/design/$ARGUMENTS/flutter.md` |
调度顺序:backend 适用 → 先调度 backend-design,成功后再调度 frontend-design / flutter-design;backend 不适用 → 可并行调度。同批次同角色复用按 `${CLAUDE_PLUGIN_ROOT}/protocols/subagent-dispatch.md` 执行。
每次调度前必须:
- 按 subagent-dispatch 协议 Read 对应 `agents/<role>.md` 全文并注入为子 agent prompt 的角色指令段
- 在 prompt 中提供最小上下文:方案名与输出路径、需求来源文件路径清单与关键摘要、Decision Log 路径及影响本端的 Active Decision 摘要、现有实现分析结论(本端相关部分)、契约源(backend 适用时传 `.ai/design/$ARGUMENTS/backend.md` 路径及 `design_result.contract_summary`;否则传现有接口清单)、分端模板路径与对应 guide 路径、`${CLAUDE_PLUGIN_ROOT}/protocols/design-agent-output-contract.md`
- 不复制 guide、protocol 或 agent 文档中的长篇规则
处理子 agent 返回:
- 只读取 `task_completion.status` 和 `design_result`,拒绝旧的顶层 `status/doc_path/contract_summary` 返回结构
- `needs_user_answer` 非空 → 按决策纪律处理,然后重新调度该端
- `task_completion.status=partial` 或 `design_result.self_check` 未通过 → 不进入合并;修复输入后重新调度,无法恢复时把生成状态写为 `failed`
- `task_completion.status=failed` → 终止该端并把生成状态写为 `failed`;不得写入该端成功状态
- frontend/flutter 的 `design_result.contract_dependencies` 必须按输出协议逐项对比 backend 的 `design_result.contract_summary`;operation、method/path、字段子集或调用方冲突时重新调度客户端设计,属于产品语义冲突时使用 `AskUserQuestion` 裁决
- 每个端成功后更新 `completed_stacks`;全部适用端 `task_completion.status=success` 后进入合并
### 7. 合并生成主文档
使用 [template.md](${CLAUDE_PLUGIN_ROOT}/skills/t-design/template.md) 生成 `.ai/design/$ARGUMENTS.md`,内容来自前序步骤与各分端文档返回:
- 目标、范围、需求来源与完整 Decision Trace(主会话编写;分端文档只保留本端 DEC 子集)
- 跨端现状概览、总体设计与关键取舍、交付端范围
- 跨端契约摘要(来自 backend `design_result.contract_summary` 或现有接口)与契约源声明
- 分端设计摘要(来自各端 `task_completion.summary`,每端 3-5 行)
- 测试与验收策略跨端汇总(来自各分端文档测试章节)
- 风险与验证动作汇总
- §8 文件影响范围:逐行合并各分端文档的文件影响表,标注来源分端;此表是 `/t-task` 的唯一拆分依据,必须覆盖全部适用端
不适用章节保留并标记"不适用"及原因。写入后对所有实际生成的文档运行:
```bash
python ${CLAUDE_PLUGIN_ROOT}/scripts/check-decision-closure.py ".ai/design/$ARGUMENTS.md" ".ai/design/$ARGUMENTS/backend.md" ".ai/design/$ARGUMENTS/frontend.md" ".ai/design/$ARGUMENTS/flutter.md"
```
命中项按 Decision Exposure Gate 分类处理;重新扫描通过前不得交付设计。随后运行 `python ${CLAUDE_PLUGIN_ROOT}/scripts/check-design.py ".ai/design/$ARGUMENTS.md"` 做确定性结构校验(章节、模板占位符、适用端文档、契约 operation、文件影响汇总和路径操作)。两项扫描全部通过后,才把 `.state.json` 写为 `complete`。
高风险、跨端或长文档设计在完成前额外调度一个无原会话背景的通用只读 agent,只提供全部设计文档和以下问题:实现入口、契约唯一来源、失败/权限/兼容路径、测试入口、文件影响范围。若读者无法从文档稳定回答或发现矛盾,修正文档并重新执行两项扫描;简单设计跳过时在收尾说明。
### 8. 分端设计验收
逐项按对应 `agents/*-design.md` 的"着重点"和质量清单验收。额外拒绝:
- API 缺少 operation ID、字段语义或具体契约源
- frontend/flutter 复制 API 字段定义,或客户端状态方案偏离对应 guide
### 9. 收尾输出
完成后在响应中明确说明:
- 主文档与各分端文档路径
- Decision Log 路径和本轮新增/复用/替代的 DEC/Q ID
- 本次设计覆盖的核心范围与适用端
- 关键风险和验证动作
- 无上下文读者测试:`passed` 或 `skipped` 及原因
- 延期问题:明确说明"无",或列出已告知用户、写入 Decision Log 且尚未到最迟解决阶段的 Q ID
- 下一步命令:高风险或复杂设计建议运行 `/t-design-check $ARGUMENTS`;简单设计可直接进入 `/t-task $ARGUMENTS`
- 如文档内容较多或结构复杂,可使用 `/t-html-show .ai/design/$ARGUMENTS.md` 生成 HTML 可视化预览
## 质量检查清单
交付前确认:
- 需求来源混合验证完成;纯技术方案已声明业务边界
- 每个适用端均由对应 agent 生成并通过其质量清单
- 主文档覆盖全部 Active Decision、Requirement/Story 和分端文件影响
- `needs_user_answer=0`;`check-decision-closure.py` 与 `check-design.py` 通过;`.state.json` 已写为 `complete`
## 失败处理
- 参数缺失:终止并给出 `/t-design [方案名称]` 示例;文件名非法:终止并说明允许字符范围;无法创建输出目录或写文件:终止并报告
- 未找到足够需求文档:按决策纪律处理(影响判断时补齐并停止;不影响时只记录不需要用户选择的证据限制)
- 子 agent 返回 `partial`、失败或超时:允许继续收集其他端诊断,但不得合并主文档;无法在本轮恢复时把 `.state.json` 写为 `failed` 并报告失败 agent 与原因
- 跨端契约冲突:以 backend 契约为准修正客户端分端设计;产品语义级冲突升级为 `AskUserQuestion`
- 代码分析失败:继续,但标记"现有实现分析不完整"

After setup, propose one small task with explicit inputs and expected output for the user to approve. Do not treat copying this prompt or successful installation as proof that the task succeeded.Copying is not installation or a successful run. Check dependencies, API costs and permissions before proceeding.
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.

Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
This page exposes the same decision, trust, audit, use-case, and install signals through the Registry API, so agents can rank this skill without scraping the UI.
