 # User Statistics Shortcuts
 
-## Background
+## Summary
 
-GitLink OpenAPI exposes user analytics endpoints, including activity, contribution heatmap, development capability, role distribution, and professional categories. gitlink-cli previously only exposed `user +me` and `user +info`.
-
-## What Changed
-
-Extended the `user` shortcut group with read-only statistics commands:
-
-- `user +activity`
-- `user +headmap`
-- `user +develop`
-- `user +role`
-- `user +major`
-
-The commands support `--login`, with fallback to `--owner` or `/users/me`. Range-based endpoints support `--start-time` and `--end-time`; heatmap supports `--year`.
-
-## OpenAPI Coverage
-
-- `GET /users/{owner}/statistics/activity`
-- `GET /users/{owner}/headmaps`
-- `GET /users/{owner}/statistics/develop`
-- `GET /users/{owner}/statistics/role`
-- `GET /users/{owner}/statistics/major`
-
-## Validation
+Adds user-centered statistics shortcuts for contributor analysis workflows:
 
 ```bash
-git diff --check
-GOPROXY=https://goproxy.cn,direct go test ./shortcuts/user ./shortcuts
-go vet ./shortcuts/user ./shortcuts
-go run . user --help
-GOPROXY=https://goproxy.cn,direct go test ./...
-go vet ./...
+gitlink-cli user +heatmap --user zhangsan --year 2026
+gitlink-cli user +statistics --user zhangsan
+gitlink-cli user +stats --user zhangsan
+gitlink-cli user +project-trends --user zhangsan
+gitlink-cli user +trends --user zhangsan
+```
+
+## Behavior
+
+- `user +heatmap` calls `GET /users/{user}/headmaps`.
+- `user +statistics` and alias `user +stats` call `GET /users/{user}/statistics`.
+- `user +project-trends` and alias `user +trends` call `GET /users/{user}/project_trends`.
+- `--user` is optional. When omitted, the shortcut resolves the current authenticated user via `/users/me`.
+- `--year` is supported by `user +heatmap`.
+- `--start-time` and `--end-time` are supported by statistics and project trend commands.
+
+## Why
+
+The `gitlink-user` Skill previously documented heatmaps, statistics, and project trends as Raw API calls. Contributor insight workflows also marked `user +heatmap`, `user +stats`, and `user +trends` as unavailable, forcing agents to approximate data from PR lists. These shortcuts expose the read-only user statistics endpoints directly and make contributor analysis more accurate.
+
+## Documentation
+
+- Updates README examples in English and Chinese.
+- Updates `skills/README.md`.
+- Updates `skills/gitlink-user/SKILL.md` to prefer shortcuts over Raw API.
+- Adds dedicated `gitlink-user` reference pages for heatmaps, statistics, and project trends.
+- Updates contributor insight guidance to use the new shortcuts when available.
+
+## Verification
+
+```bash
+go test ./shortcuts/user ./shortcuts
+go test ./...

-
-## 参数说明
-
-- `--login` 不传时优先使用全局 `--owner`，否则通过 `/users/me` 解析当前登录用户。
-- `--start-time` / `--end-time` 为 Unix 时间戳，必须是非负整数，且 `start-time <= end-time`。
-- `--year` 必须是四位年份。
-- 新增统计命令全部是只读 `GET` 操作，适合 Agent 做开源贡献画像、科研仓库成员分析和自动报告。

-# 用户贡献热力图
-gitlink-cli api GET /users/:user_id/headmaps

 # 用户统计

+
+## 注意事项
+
+- `user +heatmap`、`user +statistics`、`user +project-trends` 都是只读命令。
+- 省略 `--user` 时会先调用 `user +me` 等价的 `/users/me` 解析当前登录用户，因此需要已登录。
+- `user +stats` 和 `user +trends` 是为贡献者分析工作流保留的短别名。
