+description: "项目健康度分析（专用工作流）：采集仓库 PR/Issue 数据到 SQLite 并计算聚合指标，生成健康度报告。当用户提到「项目怎么样」「项目健康度」「项目报告」「项目状况」「项目分析」「项目整体情况」等综合分析意图时，必须使用本 skill，不要拆分为 repo/issue/pr 单独操作。"

+# gitlink-health（开源项目健康度分析技能）
+
+**CRITICAL — 开始前必须先阅读 [`../gitlink-shared/SKILL.md`](../gitlink-shared/SKILL.md)，其中包含认证、权限处理和 API 注意事项。**
+**CRITICAL — GitLink 操作只能用 `gitlink-cli`。禁止用 `gh`（GitHub CLI）操作 GitLink 资源。`gh` 仅适用于 GitHub 平台。**
+
+## 何时使用 / 何时跳过
+
+**必须使用本 skill（不要拆分为 repo/issue/pr）的场景：**
+- 用户说"项目怎么样""健康度""项目报告""项目状况""项目整体情况"
+- 用户要求综合分析一个项目的 PR、Issue 等多项指标
+- 用户要生成任何形式的项目评估报告
+
+**跳过本 skill（使用底层 skill）的场景：**
+- 用户明确只操作仓库信息（查看分支、提交等）→ `gitlink-repo`
+- 用户明确只操作 Issue（创建、查看、关闭等）→ `gitlink-issue`
+- 用户明确只操作 PR（创建、合并、查看 diff 等）→ `gitlink-pr`
+
+## 目录结构
+
+```
+- `SKILL.md`: 本文件
+- `references/queries.md`: SQL 查询参考与执行指南
+- `asset/health_report_template.md`: 报告模板
+- `data/gitlink_health.db`: SQLite 数据库
+```
+
+## 前置条件
+
+首先确保已完成认证：
+
+```bash
+gitlink-cli auth login        # 交互式登录（推荐）
+# 或
+export GITLINK_TOKEN="your-token"  # 非交互环境设置 Token
+```
+
+可通过 `gitlink-cli auth status` 验证登录状态。
+
+## 工作流程
+
+### 1. 采集仓库数据
+
+运行以下命令采集目标仓库的数据：
+```bash
+gitlink-cli health +fetch --owner OWNER --repo REPO
+```
+不传 `--owner`/`--repo` 时会自动从当前目录的 git remote 推断。命令运行后会自动生成 `~/.agents/skills/gitlink-health/data/gitlink_health.db` 文件。
+
+### 2. 查询指标
+
+读取 [references/queries.md](references/queries.md)，按其中说明确定目标仓库的 `repo_id`，再逐条执行指标查询。
+
+### 3. 生成报告
+
+按照 [references/queries.md 底部的「报告组装清单」](references/queries.md#报告组装清单)逐项执行查询并填入 [asset/health_report_template.md](asset/health_report_template.md)。**必须逐项打勾核对，输出前确认报告包含全部 14 个模板字段，不允许省略任何一项。**
+
+## 命令参考
+
+### health +fetch
+
+| 参数 | 说明 | 默认值 |
+|------|------|--------|
+| `--owner` | 仓库所有者 | 自动从 git remote 推断 |
+| `--repo` | 仓库名称 | 自动从 git remote 推断 |
+| `--db` / `-d` | SQLite 数据库路径 | `~/.agents/skills/gitlink-health/data/gitlink_health.db` |
+| `--max-pages` / `-M` | 最大页数（不限为全量） | 不限 |
+
+
+## 数据库表
+
+| 表名 | 用途 | 支持的指标 |
+|------|------|-----------|
+| `users` | 用户信息（user_name） | - |
+| `repos` | 仓库信息（repo_name, owner_id） | - |
+| `issues` | Issue 数据 | Issue 解决时长、状态分布 |
+| `pulls` | PR 数据 | PR 合并率、贡献者活跃度 |
+
+详细表结构与 API 字段映射规则见 [references/queries.md 表结构章节](references/queries.md#表结构)。

+# SQL 查询参考
+
+所有查询使用 SQLite，通过命令行逐条执行。将 `<repo_id>` 等占位符替换为实际值。
+
+**每个查询都标注了它对应报告模板中的哪些字段。按照[底部的组装清单](#报告组装清单)逐项执行，确保不遗漏。**
+
+## 表结构
+
+### users
+
+```sql
+CREATE TABLE users (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    user_name TEXT NOT NULL UNIQUE
+);
+```
+
+### repos
+
+```sql
+CREATE TABLE repos (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    repo_name TEXT NOT NULL,
+    owner_id INTEGER NOT NULL,
+    FOREIGN KEY (owner_id) REFERENCES users(id),
+    UNIQUE(repo_name, owner_id)
+);
+```
+
+### issues
+
+```sql
+CREATE TABLE issues (
+    id INTEGER PRIMARY KEY,
+    repo_id INTEGER NOT NULL,
+    number INTEGER,          -- 仓库内 Issue 编号 (project_issues_index)
+    creater_id INTEGER,      -- 创建者 → users.id
+    processor_id INTEGER,    -- 处理人 → users.id（nullable）
+    create_time TIMESTAMP,   -- 创建时间，格式 "YYYY-MM-DD HH:MM"
+    close_time TIMESTAMP,    -- 关闭时间（nullable）
+    status TEXT CHECK(status IN ('close', 'open')),
+    FOREIGN KEY (repo_id) REFERENCES repos(id),
+    FOREIGN KEY (creater_id) REFERENCES users(id),
+    FOREIGN KEY (processor_id) REFERENCES users(id)
+);
+```
+
+API 字段映射：`creater_id` ← `author.login`（detail）或 `author_login`（list），`status` ← `status.name`（detail）等于"关闭"→close。
+
+### pulls
+
+```sql
+CREATE TABLE pulls (
+    id INTEGER PRIMARY KEY,
+    repo_id INTEGER NOT NULL,
+    number INTEGER NOT NULL,    -- PR 编号
+    creater_id INTEGER,         -- 创建者 → users.id
+    status TEXT CHECK(status IN ('merged', 'closed', 'open')),
+    processor_id INTEGER,       -- 指派人 → users.id（nullable，来自 list 的 assign_user_login）
+    create_time TIMESTAMP,      -- 创建时间，ISO 格式

+    FOREIGN KEY (repo_id) REFERENCES repos(id),
+    FOREIGN KEY (creater_id) REFERENCES users(id),
+    FOREIGN KEY (processor_id) REFERENCES users(id)
+);
+```
+
+API 字段映射：`status` ← `pull_request_status`（0=open, 1=merged, 2=closed），`creater_id` ← `author_login`。
+
+## 1. 确定目标仓库
+
+数据库可能包含多个仓库的数据，查询前需先获取目标仓库的 `repo_id`：
+
+```bash
+# 列出所有仓库
+sqlite3 data/gitlink_health.db "SELECT r.id, u.user_name AS owner, r.repo_name FROM repos r JOIN users u ON r.owner_id = u.id;"
+
+# 根据 owner/repo 精确查找
+sqlite3 data/gitlink_health.db "SELECT r.id FROM repos r JOIN users u ON r.owner_id = u.id WHERE u.user_name = '<owner>' AND r.repo_name = '<repo>';"
+```
+
+## 2. Issue 解决时长

+**按以下顺序逐项执行查询、填入模板。每完成一项打勾，最终输出前核对所有 ✅ 是否齐全。**
+
+- [ ] **已关闭 Issue 数** → 执行 2.2，取 `closed_issues_count`
+- [ ] **平均天数** → 执行 2.2，取 `avg_days`（保留 1 位小数）
+- [ ] **中位数** → 执行 2.2，取 `median_days`（保留 1 位小数）
+- [ ] **最短 x 天** → 执行 2.2，取 `min_days`（保留 1 位小数）
+- [ ] **最长 x 天** → 执行 2.2，取 `max_days`（保留 1 位小数）
+- [ ] **解决时长分布** → 执行 2.3，汇总：1天内 = `'< 1天'` 数，1周内 = `1-3天 + 3-7天`，1个月内 = `7-30天`
+- [ ] **合并率 x%** → 执行 3.1，取 `merge_rate * 100`（整数）
+- [ ] **总数** → 执行 3.1，取 `total_prs`
+- [ ] **已合并** → 执行 3.1，取 `merged_count`
+- [ ] **开放** → 执行 3.1，取 `open_count`
+- [ ] **已关闭** → 执行 3.1，取 `closed_count`
+- [ ] **活跃贡献者（最近一个月）** → 执行 4.1，设 start_date = 30天前
+- [ ] **新增贡献者（最近一个月）** → 执行 4.2，设 start_date = 30天前
+- [ ] **TOP 贡献者** → 执行 4.3，取前 5~10 名

+**输出前核对：报告必须包含上述全部 14 个字段，不允许省略任何一个。**
