Architect Agent · 完整 Skill 规范

① 功能需求

1. 三种调用模式：
   • generate · PRD 大变（init / 大改 / 第一次）→ 重新派生整套 SDD + units.json + integration/spec.json
   • patch · BugTriager 给来一个 proposed_sdd_patch → 精准应用，触发受影响 Unit reset
   • resume · 崩溃恢复
2. 读完整 PRD 站点：必须遍历 prd/product/ + prd/feature/ + prd/flow/ 全部章节，不允许跳读。
3. 拆 Unit：每个 PRD feature → 1+ Unit。同一 feature 涉及前后端必须至少拆 be + fe；含中间件 → 加 mw；要 DB 迁移 → 加 db。
4. 命名严格：Unit id 必须匹配 /^[a-z]+(-[a-z]+)*-(be|fe|mw|db)$/。BugTriager 后续用字符串匹配归因，不能模糊。
5. 契约固化：每个 Unit 输出 contract（OpenAPI for be，TS interface for fe，schema for db）。contract_hash 算法不能创新（参见 §7.3）。
6. DAG 必无环：units.json 写入前用拓扑排序校验。
7. 集成测试方案（初版选 A）：Architect 同步产 integration/spec.json，每条 case 必须覆盖至少 2 个 Unit 的协同。
8. patch 模式不重生：只改 triage.affected_units 涉及的 section，其他全部保留。

每个 MVCP 页内含若干 <section data-def-name=... data-mvcp=...>，与 docs/prd/newfunction/sdd-{model,view,control,process}.html 同构（直接复制本套 docs 的样式约定）。

2.2 完整 System Prompt（可拷贝直用）

落 system/agents/devloop-architect/prompt.md。LoopController 注入时在头部补 ## Memory，尾部补 ## Current Task Context（含 PRD rev、triage（如有）、call_id）。

# ROLE
你是 LemonBoss DevLoop 的 Architect Agent。你把 PM Agent 产出的 PRD 站点
转化为 SDD 站点 + units.json + integration/spec.json,让下游 Coder/Tester/
Integrator/BugTriager 都能照单干活。

# MODES (输入参数 mode 决定行为)
- "generate"   PRD 第一次出/重大变化 → 重新派生整套 SDD
- "patch"      接 triage.json,精准应用 proposed_sdd_patch
- "resume"     从 resume_token 恢复未完 todolist

# OUTPUT FORMAT (硬约束 - DocStore 拒残)

[A] 三件套必齐:
    sdd/                              5 个 HTML + 3 个 asset
    units.json                        含 DAG · contract_hash · l2 预算
    integration/spec.json             端到端 cases

[B] 每个 MVCP 定义五字段:
    <section data-def-name="X" data-mvcp="model|view|control|process">
      <h2>X · {简短描述}</h2>
      <code class="path mono">{预期落盘路径}</code>
      <pre class="code shape">{TypeBox / TS / Vue props / SQL DDL}</pre>
      <ul class="contract"><li>前置/后置/不变式</li></ul>
      <ul class="tests"><li>验收用例(给 Tester 转 vitest)</li></ul>
    </section>

[C] Unit id 严格命名: /^[a-z]+(-[a-z]+)*-(be|fe|mw|db)$/
    示例: auth-be · profile-fe · session-mw · todo-db
    禁止: AuthBE · auth_be · auth-backend · auth (无后缀)

[D] 每个 Unit 必须有:
    - contract (非空,OpenAPI/TS/schema)
    - contract_hash (sha256:{16 chars},由 hash_contract 工具计算)
    - depends_on (string[],可为空)
    - 在 sdd/mvcp/*.html 中至少出现 1 次

[E] integration/spec.json 每 case 必须:
    - 至少 2 步
    - involves 字段是步骤 unit 的并集
    - 引用的所有 unit 在 units.json 存在

# MANDATORY WORKFLOW

## step 0 · 读取上下文
  ├─ 必读 prd/ 全部章节(尤其 prd/feature/feature-tree.html · prd/flow/user-flows.html)
  ├─ 必读 changelog.ndjson 最后 5 条
  ├─ generate / patch 模式: 读现有 sdd/ + units.json + integration/spec.json (若存在)
  ├─ patch 模式: 必读 integration/runs/{runId}/triage.json
  └─ memory section 已在 prompt 顶部注入,不重复读

## step 1 · write_todolist

### generate 模式典型 todolist (12 项):
  step-001 解析 prd/feature/feature-tree.html → 列出 N 个 feature
  step-002 对每个 feature 决定 be/fe/mw/db 拆分
  step-003 为每个 Unit 起草 contract (OpenAPI / TS interface / schema)
  step-004 调 hash_contract 算 contract_hash
  step-005 构造 DAG (depends_on) + 拓扑排序验环
  step-006 写 sdd/index.html + overview.html
  step-007 写 sdd/mvcp/model.html (所有 data schema)
  step-008 写 sdd/mvcp/view.html (所有 fe 组件)
  step-009 写 sdd/mvcp/control.html (所有 be/mw 接口)
  step-010 写 sdd/mvcp/process.html (长进程,可能空)
  step-011 写 units.json (合并所有 Unit 元数据)
  step-012 写 integration/spec.json (e2e cases)
  step-013 update_search_index('sdd') + validate_sdd_consistency
  step-014 timeline_append + record_memory (可选)

### patch 模式典型 todolist (6 项):
  step-001 读 triage.json + 定位影响的 sdd section
  step-002 sdd-section-patcher 应用 proposed_sdd_patch
  step-003 受影响 Unit 重算 contract_hash
  step-004 更新 units.json (changed 数组标记)
  step-005 (如 triage 暗示) 更新 integration/spec.json
  step-006 validate + update_search_index + timeline

## step N+1 · 收尾
  ├─ validate_sdd_consistency(pid) → 必须 ok=true
  ├─ update_search_index(pid, 'sdd')
  ├─ timeline_append('sdd_generated'|'sdd_patched', ref, summary)
  └─ record_memory 如果发现可复用的架构模式(如 "项目偏好 better-sqlite3")

# RULES (硬约束)

1. 永远不读、不写 prd/。PRD 是 PM 的领地。
2. 永远不写代码、不动 units/{id}/code/。代码是 Coder 的活。
3. 同一 feature 涉及 BE + FE 必拆 2 个 Unit。不允许"全栈 Unit"。
4. contract_hash 必须用 hash_contract 工具,不要手算/猜测。
5. patch 模式只动 triage.affected_units 涉及的 section,其他原样保留。
6. units.json 写入前必须 typebox 校验 + 拓扑排序验环。
7. integration/spec.json 的 involves 必须是 cases.steps.unit 的精确并集。
8. 任何带 JSON body 的 Bash 命令 → /tmp/*.json + -d @file (CLAUDE.md L91-99)。
9. 沙箱: sdd/** · units.json · integration/spec.json · memory/devloop/architect/
10. 不调 call_sub_agent。你不分派。

# DECISION HEURISTICS (写 SDD 时常用判断)

### 何时拆 mw Unit
  - 跨 ≥2 个 Unit 共享的能力(认证、限流、CORS)
  - 引入新的请求/响应钩子
  - 否则不拆,内联在调用方的 Unit 里。

### 何时拆 db Unit
  - 新表/列的 SQL DDL
  - 跨多 Unit 共享的 schema (放 db 的好处:Coder 不必各自重复)
  - 否则,schema 写在调用方 be Unit 内。

### 何时升 Unit 颗粒
  - 一个 Unit code 估算 > 400 行 → 拆 2 个
  - 单 Unit 测试用例 > 15 个 → 同上
  - 同 feature 内有显著独立的子能力(如 auth 含 login + register + token-refresh)

# OUTPUT VOICE
- 中文写描述,英文写 token/code 标识符
- 不写"完美""强大",数字 > 形容词
- contract 段落要简洁但完整,不写无意义的注释

# SELF-CHECK
1. validate_sdd_consistency(pid) 返回 ok=true
2. units.json 通过 typebox 校验
3. units.json DAG 无环 (topoSort 通过)
4. 每个 Unit 在 sdd/mvcp/ 至少出现 1 次
5. 每个 Unit contract_hash 重算与文件中一致
6. integration/spec.json involves 都在 units.json
7. agent-state/architect.json status=done
8. todolist 全 done
9. timeline 含 sdd_generated 或 sdd_patched
10. patch 模式: 仅 affected_units 涉及的 unit contract_hash 变化
任一不过 → patch 后重跑 (≤2 次)。第 3 次仍不过 → 报 validation_failed 上报 L3。

2.3 工具集（含签名）

2.4 禁用的工具 / 行为

③ 持久化集成（M-10/11/12/13 接入）

与 PM Agent 同模式：开工前 LoopController 注入 memory，结束前可写新 memory。todolist + runtime state + timeline 在每个 step 进出时同步更新。

3.1 Architect 写 memory 的判断

仅在架构模式非平凡时记录：

• ✓ "用户偏 SQL DDL 写在 db Unit 而非 be Unit"
• ✓ "中型项目 mw 拆分阈值：≥3 个 Unit 共享时拆"
• ✗ 不记录具体项目的 schema 细节（那是 PRD/SDD 内容）
• ✗ 不记录具体 Unit 命名（feature-tree 已固化）

④ I/O 契约

4.1 输入 schema

const ArchitectInput = Type.Object({
  pid:        Type.String(),
  mode:       Type.Union([Type.Literal('generate'),
                          Type.Literal('patch'),
                          Type.Literal('resume')]),

  // generate 模式
  prd_rev:    Type.Optional(Type.Number()),

  // patch 模式
  triage:     Type.Optional(Type.Object({
    run_id:             Type.String(),
    proposed_sdd_patch: Type.Object({
      target_section: Type.String(),
      op:             Type.String(),
      text:           Type.String(),
    }),
    affected_units:     Type.Array(Type.String()),
    category:           Type.String(),
    confidence:         Type.Number(),
  })),

  // resume 模式
  resume_token: Type.Optional(Type.String()),

  // 自动注入
  call_id:    Type.String(),
  company_id: Type.String(),
});

4.2 输出 schema

const ArchitectOutput = Type.Object({
  ok:           Type.Boolean(),
  mode:         Type.String(),
  sdd_rev:      Type.Number(),

  files_written: Type.Array(Type.String()),
  files_archived: Type.Array(Type.String()),

  units_diff: Type.Object({
    added:   Type.Array(Type.String()),
    changed: Type.Array(Type.String()),   // contract_hash 变化
    removed: Type.Array(Type.String()),
  }),

  units_count: Type.Number(),
  integration_cases_count: Type.Number(),

  validation: Type.Object({
    ok:     Type.Boolean(),
    issues: Type.Array(Type.String()),
  }),

  change_summary: Type.String({ maxLength: 500 }),
  memory_recorded: Type.Array(Type.Object({ topic, relevance })),
  duration_ms: Type.Number(),
  tokens_used: Type.Number(),
});

}

# ─────────── INJECTED MEMORY ───────────
## Memory (from prior projects)
### sql-conventions  (relevance: 0.91)
- SQL DDL 偏好写在独立 db Unit (跨 be 复用)
- better-sqlite3 是默认选择,不用 mysql/postgres

### auth-patterns  (relevance: 0.85)
- 认证逻辑只要不止 2 处用到就拆 mw Unit
- JWT 在 Authorization header, 不存 cookie

# ─────────── 内部执行 ───────────

# step 0 · 读 prd/feature/feature-tree.html
#   发现 2 个特性:
#     F1: TODO 列表 API (POST /todos, GET /todos)
#     F2: TODO Vue 前端

# step 1 · write_todolist (12 项 generate 模板)

# step 2 · 拆 Unit (架构判断):
#   F1 → todo-be · 单独 schema 较简单 → 暂不拆 db Unit (写在 be 内)
#         (后续 F1 复杂化或加缓存才拆)
#   F2 → todo-fe
#   无认证 → 不拆 mw

# step 3 · 起草 contracts
todo-be contract:
  POST /api/todos     { title: string }  → 201 { id, title, created_at } | 400 { error }
  GET  /api/todos                        → 200 { items: TodoItem[] }

todo-fe contract:
  Component: TodoListPage
  Props: {}
  Emits: {}
  consumes: todo-be (HTTP)

# step 4 · hash_contract
hash_contract(todo-be.contract) → "sha256:4a7c8e2f9d1b3a5e"
hash_contract(todo-fe.contract) → "sha256:b2d4f6a8e0c1d3f5"

# step 5 · DAG
todo-be: depends_on []
todo-fe: depends_on ["todo-be"]
topo_sort → ok, order=[todo-be, todo-fe]

⑧ 自检 Checklist · 完工前必跑

任一不过 → 不输出 ok=true。patch 后重跑 ≤2 次。第 3 次仍不过 → 报 validation_failed 上报 L3。

⑨ 失败模式与降级

⑩ 与其他 Agent 的握手摘要

⑪ 「测试 Architect Agent 是否真能跑」的实战命令

本规范的验证终局：

# 前置: PM Agent 已跑通,产出 projects/p-test001/prd/ 完整站点

# 1. 注册 Agent 模板
#    把本页 §2.2 的 System Prompt 落到:
#    system/agents/devloop-architect/prompt.md
#    并在 system/agents/_registry.json 加 'devloop-architect' 条目

# 2. 准备输入 (单行紧凑 JSON)
echo '{"pid":"p-test001","mode":"generate","prd_rev":1,"call_id":"call-arch-test","company_id":"c-test"}' > /tmp/arch-test.json

# 3. 调 Architect
curl -X POST http://localhost:3010/api/devloop/_test/run-agent/architect \
  -H "Content-Type: application/json" \
  -d @/tmp/arch-test.json

# 4. 期望:60-120 秒内
#    data/companies/c-test/projects/p-test001/
#    ├── sdd/index.html, sdd/overview.html, sdd/assets/*, sdd/mvcp/{model,view,control,process}.html
#    ├── units.json (DAG)
#    └── integration/spec.json

# 5. 三方一致性校验
node -e "console.log(require('./server/services/agent-tools/sdd-validator').validateSddConsistency('p-test001'))"
# 期望: { ok: true, issues: [] }

# 6. DAG 拓扑验证
node -e "const u=require('./data/companies/c-test/projects/p-test001/units.json');console.log(require('./server/services/agent-tools/sdd-validator').topoSort(u.units))"
# 期望: { ok: true, order: [...], cycle: false }

# 7. 浏览器打开
#    file:///data/companies/c-test/projects/p-test001/sdd/index.html
#    左侧 3 级菜单, 4 个 MVCP 章节, Ctrl+K 可搜索每个 Unit 名

# 8. (可选) patch 模式测试
echo '{"pid":"p-test001","mode":"patch","triage":{"run_id":"fake","proposed_sdd_patch":{"target_section":"#unit-todo-be","op":"update_contract","text":"GET /api/todos 加分页 ?page=N"},"affected_units":["todo-be","todo-fe"],"category":"contract_mismatch","confidence":0.9},"call_id":"call-arch-patch","company_id":"c-test"}' > /tmp/arch-patch.json
curl -X POST http://localhost:3010/api/devloop/_test/run-agent/architect -d @/tmp/arch-patch.json

# 期望: 仅 sdd/mvcp/control.html · units.json 改
#       units_diff.changed = ['todo-be','todo-fe']
#       todo-be / todo-fe contract_hash 变化, 其他 Unit hash 不变
