-# AI 驱动的 OKR 自动生成与同步
-
-## Context
-
-DevPerf 已具备完整的 Git 同步管线（Gitea → gitCommits 表）和 OKR CRUD 系统。
-当前 OKR 需人工创建，缺少与 Git 提交的联动。
-
-**目标**：每次 Git 同步后，AI 分析新增 commit messages，按仓库维度：
- 新增 KR — commit 提到的功能点尚无对应 KR
- 更新进度 — commit 涉及已有 KR 的功能
- 标记完成 — commit 明确表示功能已完成
-
-**分析粒度**：按仓库（每个仓库的新增 commits 做一次 AI 分析，prompt 中包含提交人信息）
-**OKR 归属**：commit 的提交人 = KR/Objective 的负责人（ownerId），通过 gitCommits.userId 关联
-**增量机制**：每条 commit 只分析一次，分析后打标记，后续同步不再重复处理
-
---
-
-## 第一阶段：Schema 变更
-
-**文件**: `backend/src/db/schema.ts`
-
-### 1a. 新增 `ai_analyzed_commits` 表（增量标记，防止重复分析）
-
-```
-aiAnalyzedCommits:
-  id            varchar(50) PK
-  commitSha     varchar(200) NOT NULL UNIQUE   -- 对应 gitCommits.sha
-  batchId       varchar(50) NOT NULL           -- 一次 AI 调用的批次 ID
-  createdAt     datetime NOT NULL
-```
-
-**核心作用**：每次同步后，只提取 `gitCommits` 中尚未出现在此表的 commit 送给 AI。分析完成后立即写入标记，确保该 commit 不会被重复处理。
-
-### 1b. objectives 表加字段
-
- `source` varchar(50) default `'manual'` — 值: `'manual'` | `'ai_generated'`
-
-### 1c. keyResults 表加字段
-
- `source` varchar(50) default `'manual'` — 值: `'manual'` | `'ai_generated'`
- `sourceKey` varchar(300) nullable — AI 分配的功能标识符（如 `"user-login"`），用于语义去重
-
-### 1d. keyResults.status 扩展
-
-现有 `'active' | 'paused' | 'cancelled'`，新增 `'completed'`。
-字段类型是 varchar，无需改 DDL，只需让 `recalcObjectiveProgress` 正确处理 completed。
-
-### 1e. syncLogs.source 枚举扩展
-
-将 `mysqlEnum('source', ['plane', 'gitea'])` 改为 `['plane', 'gitea', 'ai_okr']`。
-
---
-
-## 第二阶段：AI 配置与 LLM 客户端（豆包 Doubao）
-
-### 2a. 环境变量 (`backend/src/config.ts`)
-
-新增：
-```typescript
-AI_ENABLED: z.coerce.boolean().default(false),
-AI_API_KEY: z.string().default(''),
-AI_MODEL: z.string().default('doubao-seed-2-0-pro-260215'),
-AI_BASE_URL: z.string().default('https://ark.cn-beijing.volces.com/api/v3'),
-```
-
-**.env 示例**：
-```env
-AI_ENABLED=true
-AI_API_KEY=846b6981-9954-4c58-bb39-63079393bdb8
-AI_MODEL=doubao-seed-2-0-pro-260215
-AI_BASE_URL=https://ark.cn-beijing.volces.com/api/v3
-```
-
-### 2b. 新建 `backend/src/services/llm-client.ts`
-
-使用豆包（火山引擎 Ark）API，原生 fetch 实现，零额外依赖。
-
-**豆包 API 调用格式**：
-
-```typescript
-// POST https://ark.cn-beijing.volces.com/api/v3/chat/completions
-// Header: Authorization: Bearer {AI_API_KEY}
-// Header: Content-Type: application/json
-
-export async function callLLM(systemPrompt: string, userPrompt: string): Promise<string> {
-  const url = `${config.AI_BASE_URL}/chat/completions`;
-
-  const body = {
-    model: config.AI_MODEL,           // "doubao-seed-2-0-pro-260215"
-    messages: [
-      { role: "system", content: systemPrompt },
-      { role: "user", content: userPrompt }
-    ],
-    temperature: 0.3,                  // 低温度保证输出稳定
-    response_format: { type: "json_object" }  // 强制 JSON 输出
-  };
-
-  const response = await fetch(url, {
-    method: 'POST',
-    headers: {
-      'Authorization': `Bearer ${config.AI_API_KEY}`,
-      'Content-Type': 'application/json',
-    },
-    body: JSON.stringify(body),
-    signal: AbortSignal.timeout(60000),  // 60s 超时
-  });
-
-  if (!response.ok) {
-    throw new Error(`Doubao API error: ${response.status} ${await response.text()}`);
-  }
-
-  const data = await response.json();
-  return data.choices[0].message.content;
-}
-```
-
-**要点**：
- 豆包 Ark API 兼容 OpenAI `/chat/completions` 格式
- 使用 `response_format: { type: "json_object" }` 强制返回 JSON
- 超时 60s，失败重试 1 次（间隔 3s）
- `temperature: 0.3` 保证分析结果稳定一致
-

-
-## 第三阶段：核心服务 — `backend/src/services/okr-ai-sync.ts`
-
-### 整体流程
-
-```
-analyzeCommitsForOKR()
-  │
-  ├─ 1. gatherUnanalyzedCommits()
-  │     SELECT gc.* FROM git_commits gc
-  │     LEFT JOIN ai_analyzed_commits aac ON gc.sha = aac.commit_sha
-  │     WHERE aac.id IS NULL
-  │     → 按 repoName 分组（每个仓库一批）
-  │
-  ├─ 2. 遍历每个仓库的未分析 commits：
-  │     a. 通过 projectRepos 找到该仓库关联的 projectId
-  │     b. 获取该项目当前所有 Objectives + KRs（含 sourceKey）
-  │     c. 构建 AI prompt（该仓库的新 commits，含每条 commit 的提交人信息 + 项目现有 OKR）
-  │     d. 调用豆包 AI → 解析 JSON 响应
-  │     e. 执行 AI 返回的 actions：
-  │        - create_objective → 创建时 ownerId = commit 提交人的 userId（AI 返回 authorUserId）
-  │        - create_kr → 先查 sourceKey 防重 → 不存在才创建，归属到对应提交人
-  │        - update_progress → 更新 currentValue + 写 krLog
-  │        - complete_kr → status='completed' + 写 krLog
-  │     f. 重算 Objective progress
-  │     g. 标记这批 commits 为已分析（写入 aiAnalyzedCommits）
-  │
-  └─ 3. 写入 syncLogs (source='ai_okr')
-```
-
-### 增量更新机制（核心）
-
-```
-第一次同步：
-  gitCommits: [A, B, C, D, E]
-  aiAnalyzedCommits: []
-  → 未分析: [A, B, C, D, E] → 全部送 AI → 分析后标记 [A, B, C, D, E]
-
-第二次同步（新增了 F, G）：
-  gitCommits: [A, B, C, D, E, F, G]
-  aiAnalyzedCommits: [A, B, C, D, E]
-  → 未分析: [F, G] → 只送 F, G 给 AI → 分析后标记 [F, G]
-
-第三次同步（无新增）：
-  → 未分析: [] → 跳过，不调用 AI
-```
-
-### AI Prompt 设计
-
-**System Prompt**:
-```
-你是一个开发团队的 OKR 管理助手。你的任务是分析 git commit 记录，管理项目的 OKR（目标与关键成果）。
-
-你需要分析提交记录，输出 JSON 格式的操作指令：
-
-判断逻辑：
- commit 包含 "完成"、"done"、"finished"、"实现完毕" 等完成语义 → 对应 KR 标记完成
- commit 是 feat/feature 类型但未完成 → 更新对应 KR 进度（根据描述估算百分比）
- commit 涉及的功能在现有 KR 中不存在 → 创建新 KR（需同时提供时间节点）
- fix/refactor/chore/docs 类 commit → 只在涉及明确功能时才操作
- 不要为同一个功能创建重复的 KR，已有相同 sourceKey 的直接更新
-
-新建 Objective 规则：
- 如果提交涉及的功能没有归属到任何已有 Objective → 可以创建新 Objective
- Objective 的 startDate 和 endDate 由你根据提交内容和功能复杂度判断
- period 格式为 "YYYY-Qn"（如 "2026-Q2"），根据 endDate 推算
-
-新建 KR 规则：
- targetValue = 100, unit = "%"
- 根据 commit 语义估算 currentValue（初步实现=30, 基本完成=70, 完成=100）
- sourceKey 用小写英文短横线格式（如 "user-login", "payment-module"）
- title 用中文描述
- startDate 和 endDate 由你根据功能复杂度和提交时间判断
-```
-
-**User Prompt 模板**:
-```
-仓库：{{repoName}}
-所属项目：{{projectName}}
-当前日期：{{today}}
-
-该项目已有的 OKR：
-{{#each existingObjectives}}
-Objective: id={{id}}, title="{{title}}", period={{period}}, 时间={{startDate}}~{{endDate}}, 进度={{progress}}%
-  Key Results:
-  {{#each keyResults}}
-  - id: {{id}}, title: "{{title}}", sourceKey: "{{sourceKey}}", status: {{status}}, 进度: {{currentValue}}/{{targetValue}}, 时间: {{startDate}}~{{endDate}}
-  {{/each}}
-{{/each}}
-
-{{如果没有已有 OKR: "该项目暂无 OKR 记录。"}}
-
-该仓库的开发人员（commit 提交人 → 系统用户映射）：
-{{#each authors}}
- userId: "{{userId}}", 姓名: {{displayName}}
-{{/each}}
-
-该仓库新增的提交记录（按时间排序，均为增量，之前的已处理过）：
-{{#each commits}}
- [{{committedAt}}] 提交人: {{authorName}}(userId={{userId}}) {{sha前7位}}: {{message}} (+{{additions}}/-{{deletions}})
-{{/each}}
-
-请分析以上提交，返回 JSON。注意：每个 action 都必须带 ownerId 字段，值为提交人的 userId，表示该 OKR 归谁负责。
-{
-  "actions": [
-    {
-      "type": "create_objective",
-      "ownerId": "提交人的userId",
-      "title": "目标标题",

-      "krId": "已有KR的id",
-      "reasoning": "..."
-    }
-  ],
-  "summary": "一句话总结该仓库近期开发动态"
-}
-如果没有需要操作的内容，返回 {"actions": [], "summary": "..."}
-```
-
-### 防重复策略（三层保障）
-
-| 层级 | 机制 | 说明 |
-|------|------|------|
-| **Commit 级** | `aiAnalyzedCommits` 表 | 已分析的 SHA 打标记，下次同步时过滤掉，不再送给 AI |
-| **KR 级** | `sourceKey` 唯一性检查 | 创建前查 DB，同 Objective 下同 sourceKey 只允许一条，重复则转为 update |
-| **Objective 级** | 项目下已有 OKR 传入 prompt | AI 看到完整上下文，避免建议创建重复目标 |
-
-### OKR 负责人归属
-
- commit 有 `userId`（通过 author-matching 映射到系统用户）
- AI prompt 中包含每条 commit 的提交人信息（userId + displayName）
- AI 返回 action 时必须携带 `ownerId`，即该 OKR 归哪个提交人负责
- 执行时：`create_objective` 的 `ownerId` = AI 指定的 userId，`create_kr` 同理
- 跳过 `userId` 为 null 的 commits（作者未映射到系统用户）
-
-**示例**：仓库 rtc_backend 有张三、李四两个人提交代码
- 张三的 commit 涉及"用户登录" → AI 创建 KR 归属张三
- 李四的 commit 涉及"支付模块" → AI 创建 KR 归属李四
- 同一个 Objective 下可以有不同负责人的 KR
-
-### 时间节点（由 AI 判断）
-
- **不再固定取当前季度**，而是由 AI 根据以下信息决定：
-  - commit 的提交时间
-  - 功能的复杂度（从 commit 内容推断）
-  - 已有 OKR 的时间范围（避免冲突）
- AI 返回的 `startDate`、`endDate` 直接写入 Objective 和 KR
- `period` 根据 endDate 自动推算（复用已有 `dateToPeriod()`）
- Objective 创建后，其日期范围由 AI 决定，后续也可由 AI 在新的分析中调整
-
-### 完成判定
-
-AI 返回 `complete_kr` action 时：
-1. `currentValue = targetValue`（即 100）
-2. `status = 'completed'`
-3. 写 krLog：`action='completed'`, `detail='AI 根据 commit {sha} 判定完成：{reasoning}'`
-4. `recalcObjectiveProgress()` 时 completed 的 KR 按 100% 计入
-
---
-
-## 第四阶段：集成到同步流程
-
-### 4a. 修改 `backend/src/sync/scheduler.ts`
-
-```typescript
-import { analyzeCommitsForOKR } from '../services/okr-ai-sync';
-
-// 在 syncGitea() 之后调用
-giteaJob = new Cron('0 2,19 * * *', async () => {
-  await syncGitea();
-  if (config.AI_ENABLED) {
-    console.info('[SCHEDULER] AI OKR 分析开始...');
-    await analyzeCommitsForOKR().catch(e =>
-      console.error('[SCHEDULER] AI OKR analysis failed:', e)
-    );
-  }
-});
-```
-
-### 4b. 新增 API 端点 (`backend/src/routes/okr.ts`)
-
-| 方法 | 路径 | 说明 |
-|------|------|------|
-| POST | `/api/okr/ai-analyze` | 手动触发 AI 分析（admin/manager） |
-| POST | `/api/okr/ai-analyze/preview` | 预览模式：返回 AI 建议但不执行 |
-
-### 4c. 修改 `backend/src/services/okr.ts`
-
- 导出 `dateToPeriod()` 函数供 okr-ai-sync 使用
- `recalcObjectiveProgress()` 增加对 `status === 'completed'` 的处理（按 100% 计入进度）
-
---
-
-## 第五阶段：DB 迁移
-
-新增迁移文件 `backend/drizzle/0002_add_ai_okr_fields.sql`：
-
-```sql
-- 新表：增量标记（已分析过的 commit 不再重复处理）
-CREATE TABLE ai_analyzed_commits (
-  id VARCHAR(50) PRIMARY KEY,
-  commit_sha VARCHAR(200) NOT NULL,
-  batch_id VARCHAR(50) NOT NULL,
-  created_at DATETIME NOT NULL,
-  UNIQUE INDEX uniq_analyzed_sha (commit_sha)
-);
-
-- objectives 加字段
-ALTER TABLE objectives ADD COLUMN source VARCHAR(50) DEFAULT 'manual';
-
-- key_results 加字段
-ALTER TABLE key_results ADD COLUMN source VARCHAR(50) DEFAULT 'manual';
-ALTER TABLE key_results ADD COLUMN source_key VARCHAR(300) NULL;
-
-- syncLogs source 枚举扩展
-ALTER TABLE sync_logs MODIFY COLUMN source ENUM('plane', 'gitea', 'ai_okr') NOT NULL;
-```
-
---
-
-## 关键文件清单
-
-| 文件 | 操作 | 说明 |
-|------|------|------|
-| `backend/src/db/schema.ts` | 修改 | 新表 + 新字段 |
-| `backend/src/config.ts` | 修改 | 豆包 AI 环境变量 |
-| `backend/src/services/llm-client.ts` | **新建** | 豆包 API 调用封装 |
-| `backend/src/services/okr-ai-sync.ts` | **新建** | 核心 AI 分析 + 增量更新逻辑 |
-| `backend/src/services/okr.ts` | 修改 | 导出 dateToPeriod, completed 状态处理 |
-| `backend/src/sync/scheduler.ts` | 修改 | 同步后触发 AI 分析 |
-| `backend/src/routes/okr.ts` | 修改 | 新增手动触发端点 |
-| `backend/drizzle/0002_*.sql` | **新建** | DB 迁移 |
-
---
-
-## 实施顺序
-
-1. Schema 变更 + 迁移文件（第一、五阶段）
-2. config.ts 加豆包 AI 环境变量（第二阶段 2a）
-3. llm-client.ts — 豆包 API 封装（第二阶段 2b）
-4. okr.ts 小改（导出 dateToPeriod + completed 处理）
-5. okr-ai-sync.ts 核心服务（第三阶段）
-6. scheduler.ts 集成 + 新 API 端点（第四阶段）
-7. 端到端测试
-
---
-
-## 验证方案
-
-1. 配置 `.env`：`AI_ENABLED=true`，`AI_API_KEY=...`，`AI_MODEL=doubao-seed-2-0-pro-260215`
-2. 确保数据库中已有项目、用户、项目-仓库绑定、git commits 数据
-3. 调用 `POST /api/okr/ai-analyze/preview` 查看 AI 返回的 actions（不写库）
-4. 确认 actions 合理后，调用 `POST /api/okr/ai-analyze` 执行
-5. 通过 `GET /api/okr` 验证 OKR 数据已生成，时间节点由 AI 合理设定
-6. 再次调用 `POST /api/okr/ai-analyze`，确认不会重复生成（增量标记生效）
-7. 手动触发 Git 同步拉到新 commits，再次分析，确认只处理新增 commits
-8. 检查 krLogs 中有 AI 操作记录
-9. 前端 OKR 页面查看显示是否正常
-
---
-
-## 错误处理
-
-| 场景 | 处理 |
-|------|------|
-| AI_ENABLED=false 或 API key 为空 | 静默跳过，不影响 Git 同步 |
-| 豆包 API 返回非 JSON | 尝试用正则提取 ```json 块，失败则记 syncLogs error |
-| 豆包 API 超时（60s） | 记错误日志，commits 保持"未分析"状态，下次同步重试 |
-| AI 建议更新不存在的 KR | 跳过该 action，记 warning |
-| AI 建议创建重复 sourceKey 的 KR | 转为 update_progress |
-| commit 的 repo 没有绑定到任何项目 | 跳过该仓库的分析 |
-| 某个仓库无新增 commits | 跳过，不调用 AI |

-你需要分析提交记录，输出 JSON 格式的操作指令：
-
-判断逻辑：
- commit 包含 "完成"、"done"、"finished"、"实现完毕" 等完成语义 → 对应 KR 标记完成
- commit 是 feat/feature 类型但未完成 → 更新对应 KR 进度（根据描述估算百分比）
- commit 涉及的功能在现有 KR 中<EFBFBD><EFBFBD>存在 → 创建新 KR（需同时提供时间节点）
- fix/refactor/chore/docs 类 commit → 只在涉及明确功能时才操作
- 不要为同一个功能创建重复的 KR，已有相同 sourceKey 的直接更新
-
-新建 Objective 规则：
- 如果提交涉及的功能没有归属到任何已有 Objective → 可以创建新 Objective
- Objective 的 startDate 和 endDate 由你根据提交内容和功能复杂度判断
- period 格式为 "YYYY-Qn"（如 "2026-Q2"），根据 endDate 推算
-
-新建 KR 规则：
- targetValue = 100, unit = "%"
- 根据 commit 语义估算 currentValue（初步实现=30, 基本完成=70, 完成=100）
- sourceKey 用小写英文短横线格式（如 "user-login", "payment-module"）
- title 用中文描述
- startDate 和 endDate 由你根据功能复杂度和提交时间判断
