-### 用户画像
-
-`profile` 暴露 GitLink 原生的用户画像统计（开发能力、角色定位、专业定位、近期活动、贡献热力图）。
-省略 `--user` 时默认使用当前认证用户。
+### 附件和元数据
 
 ```bash
-# 开发能力评分 + 语言分布
-gitlink-cli profile +ability --user zhangsan
+# 查询许可证模板
+gitlink-cli meta +licenses --name MIT
 
-# 角色定位 / 专业（学科）定位
-gitlink-cli profile +role --user zhangsan
-gitlink-cli profile +major --user zhangsan
+# 查询 .gitignore 模板
+gitlink-cli meta +ignores --name Go
 
-# 指定时间范围的开发能力（Unix 时间戳）
-gitlink-cli profile +ability --user zhangsan --start-time 1704067200 --end-time 1735689600
+# 预览附件上传，不修改线上数据
+gitlink-cli attachment +upload --file screenshot.png --description "issue screenshot" --dry-run
 
-# 当前用户的近期活动（每日 疑修 / 合并请求 / 提交）
-gitlink-cli profile +activity
+# 上传附件
+gitlink-cli attachment +upload --file screenshot.png --description "issue screenshot"
 
-# 指定年份的贡献热力图
-gitlink-cli profile +contribution --user zhangsan --year 2025
+# 预览删除附件
+gitlink-cli attachment +delete --uuid <uuid> --dry-run
 ```
 
-### 数据集
-
-`dataset` 管理并查询 GitLink 科研数据集（标题、描述、论文内容、许可证、所属项目）。
-
-```bash
-# 按数字项目 ID 列出一个或多个项目的数据集
-gitlink-cli dataset +list --ids 5988
-
-# 查看仓库的数据集及其附件
-gitlink-cli dataset +view --owner Gitlink --repo forgeplus
-
-# 创建 / 更新仓库数据集（先用 --dry-run 预览）
-gitlink-cli dataset +create --owner me --repo proj -t "我的数据集" -d "..." --license-id 359 --dry-run
-gitlink-cli dataset +update --owner me --repo proj -t "我的数据集" -d "更新"
-
-# 删除数据集附件（破坏性：先预览，再用 --yes 确认）
-gitlink-cli dataset +delete-attachment --owner me --repo proj --uuid <uuid> --dry-run
-gitlink-cli dataset +delete-attachment --owner me --repo proj --uuid <uuid> --yes
-```
-
-> 注意：`dataset +list`（平台数据集查询）已在生产 gitlink.org.cn 验证可用。按仓库的 `+view`/`+create`/`+update` 遵循已发布的 OpenAPI 契约，但生产环境尚未部署（当前返回 404），待平台上线后即可生效。

+# Meta and Attachment Shortcuts
+
+## Summary
+
+This change adds high-level shortcuts for GitLink OpenAPI endpoints that were previously only reachable through Raw API:
+
+- `meta +licenses` → `GET /api/licenses.json`
+- `meta +ignores` → `GET /api/ignores.json`
+- `attachment +upload` → `POST /api/attachments.json`
+- `attachment +delete` → `DELETE /api/attachments/{uuid}.json`
+
+## User Value
+
+- Maintainers can query license and `.gitignore` templates before creating repositories.
+- Agents can upload files once, capture the returned attachment UUID/URL, and reuse it in Issue/PR/comment workflows.
+- Destructive attachment deletion supports `--dry-run` to preview the request before remote mutation.
+
+## Validation
+
+- Unit tests cover query parameters, multipart upload fields, dry-run behavior, missing local files, and deletion.
+- README and Skill docs include command examples and Agent safety guidance.

+## Shortcuts
+
+| Shortcut | 说明 | 操作类型 |
+|----------|------|----------|
+| `attachment +upload` | 上传本地文件，返回附件 UUID/URL 等信息 | ⚠️ Write Operation |
+| `attachment +delete` | 按 UUID 删除附件 | 🔴 Destructive Operation |
+
+## 参数参考
+
+### attachment +upload
+
+| 参数 | 必填 | 说明 |
+|------|------|------|
+| `--file, -f` | 是 | 本地文件路径 |
+| `--description, -d` | 否 | 附件描述 |
+| `--container-id` | 否 | 归属模型 ID，例如 Issue/PR/数据集记录 ID |
+| `--container-type` | 否 | 归属模型类型 |
+| `--dry-run` | 否 | 只预览 multipart 字段，不上传文件 |
+| `--format` | 否 | 输出格式：`json`/`table`/`yaml` |
+
+### attachment +delete
+
+| 参数 | 必填 | 说明 |
+|------|------|------|
+| `--uuid, -u` | 是 | 附件 UUID |
+| `--dry-run` | 否 | 只预览删除请求，不删除附件 |
+| `--format` | 否 | 输出格式：`json`/`table`/`yaml` |
+
+## 使用示例
+
+```bash
+# 预览上传，不修改线上数据
+gitlink-cli attachment +upload --file screenshot.png --description "复现截图" --dry-run
+
+# 上传附件
+gitlink-cli attachment +upload --file screenshot.png --description "复现截图"
+
+# 上传并绑定到业务对象
+gitlink-cli attachment +upload --file design.pdf \
+  --description "设计文档" \
+  --container-id 123 \
+  --container-type Issue
+
+# 预览删除
+gitlink-cli attachment +delete --uuid f5838d8f-451b-4793-a0f2-0278430e8207 --dry-run
+
+# 删除附件
+gitlink-cli attachment +delete --uuid f5838d8f-451b-4793-a0f2-0278430e8207
+```
+
+## Agent 工作流建议
+
+1. 确认用户要上传或删除的文件/附件 UUID。
+2. 写操作先执行 `--dry-run --format json`，展示将要调用的方法、路径和字段。
+3. 用户确认后再执行真实命令。
+4. 对上传结果，保存返回的 `id`/`url`，后续可作为 Issue、评论或数据集附件引用。

+
+**CRITICAL — 开始前建议阅读 [`../gitlink-shared/SKILL.md`](../gitlink-shared/SKILL.md)，其中包含认证、全局参数和输出格式说明。**
+
+`meta` 命令只读取公开模板数据，不修改远端资源，适合创建仓库前查询可用的许可证和 `.gitignore` 模板。
+
+## Shortcuts
+
+| Shortcut | 说明 | 操作类型 |
+|----------|------|----------|
+| `meta +licenses` | 查询许可证模板列表 | Read |
+| `meta +ignores` | 查询 `.gitignore` 模板列表 | Read |
+
+## 参数参考
+
+| 命令 | 参数 | 必填 | 说明 |
+|------|------|------|------|
+| `meta +licenses` | `--name, -n` | 否 | 按许可证名称过滤，例如 `MIT` |
+| `meta +ignores` | `--name, -n` | 否 | 按模板名称过滤，例如 `Go` |
+| 两者 | `--format` | 否 | 输出格式：`json`/`table`/`yaml` |
+
+## 使用示例
+
+```bash
+# 查询许可证模板
+gitlink-cli meta +licenses --name MIT --format json
+
+# 查询 .gitignore 模板
+gitlink-cli meta +ignores --name Go --format json
+
+# 列出全部模板
+gitlink-cli meta +licenses
+gitlink-cli meta +ignores
+```
+
+## Agent 工作流建议
+
+1. 创建仓库前先用 `meta +licenses` / `meta +ignores` 查询模板名称或 ID。
+2. 将查询结果与用户需求对齐，例如开源许可证选择、语言模板选择。
+3. 后续再调用仓库创建或更新命令，减少用户手动查网页的成本。
